formative evaluation research

por

Rex Hartson, Pardha Pyla, in The UX Book (Second Edition), 2019. Formative evaluations are meant to steer the design on the correct path so that the final product has satisfactory user experience. Alternatively, user interfaces may be evaluated at the user’s place, e.g., in the noisy environment where CT data are analyzed or even in an operating room. Thus, it is known that formal summative evaluations are judged on a number of rigorous criteria, such as validity, and that formal summative evaluation contributes to our science base. assessment of efforts prior to their completion for the purpose of improving the efforts Please note that some file types are incompatible with some mobile and tablet devices. 21-2. Because informal summative evaluation is engineering, it comes with some very strict limitations, particularly on sharing informal summative results. This part of the evaluation focuses on the process. are essential [McGuinness and O’Connor, 2010]. Life is one big, long formative evaluation. The goal of formative assessment is to monitor student learning to provide ongoing feedback that can be used by instructors to improve their teaching and by students to improve their learning.

Summative evaluation involves making judgments about the efficacy of a program or course at its conclusion. Also, sometimes the term is used to refer to a more comprehensive team evaluation, more like a team-based UX inspection. Evaluation Types When to use What it shows Why it is useful Formative Evaluation Evaluability Assessment The selection of test persons is another serious aspect. The analysis compiled over 250 publications, both quantitative and qualitative, which were found to: Evaluation is the process of examining a program, procedure, or product to estimate its function, effect, and worth. Alpha and beta testing with selected users and/or customers are appropriate evaluation methods for pre-release versions of the near-final product. Thus, formative evaluations are basically done on the fly. CHAPTER 4 Guidelines for Formative Evaluation Research in Campaign Design 55 designer. Copy and paste the following HTML into your website. Calling on a previously used participant tells them you value their help and gives them a kind of empowerment, a feeling that they are helping to make a difference in your design. It is done early with simulations and early working prototypes of designs and explores whether usability objectives are obtainable or not. This method measures change in knowledge, attitudes and behaviors of the subject. From their own far-flung cultures in psychology, human factors engineering, systems engineering, software engineering, marketing, and management they arrived at the docks of HCI with their baggage containing their own perspectives and mind-sets. The “think aloud” technique, like in early task analysis, is helpful. Guglielmo Trentin, in Networked Collaborative Learning, 2010. Perhaps the most important basic distinction in evaluation types is that between formative and summativeevaluation. Such a comparison, of course, includes validation (recall § 4.7) where the accuracy of the results related to some ground truth is determined with various distance and volume overlap metrics.

In medical visualization, typical tasks include the description of the morphology and spatial surrounding of a pathology, its classification and the assessment of its operability. Thus the reason for iteration and refinement cycles, to which evaluation is central. In sum, formal summative evaluation is an important HCI research skill, but in our view it is not part of UX practice. Identify needs. Formative Assessment Writing Activities and Research Activities Formative Assessment Activities Definition Classroom Options Writing Break Stop in the middle of class and give students two minutes to write about the lesson or topic. Finally, you can continue to evaluate a system or product even after deployment in the field via remote surveys and/or questionnaires and remote UX evaluation, a method that has the advantage of operating within the context of real-world usage. Calling on a previously used participant tells them you value their help and gives them a kind of empowerment, a feeling that they are helping to make a difference in your design. The evaluation results need to be disseminated e.g. In a similar way, a user interface is analyzed in usability inspection with respect to conformance to styleguides and potential usability problems. FERA clients include foundations and their grantees, nonprofit organizations, strategic alliances and collaborative efforts, and networks/membership associations at the local, national, and international levels. At the end of each iteration for a product version, the informal summative evaluation is used as a kind of acceptance test to compare with our UX targets and ensure that we meet our UX and business goals with the product design. Formative evaluation may focus on attainment of intermediate goals and reveal whether a certain participant has acquired given knowledge/skills. To accomplish this goal, the brief defines formative assessment, examines the research, and outlines the components needed to develop a high-quality, research-based formative assessment plan in a state, district, or school . A usability expert with background in medicine instead may also suggest alternative solutions for special tasks based on his knowledge of competing products or related projects. In general, formative usability evaluation is done to find and fix problems with an existing product in order to make it more usable. Summative Evaluation often aims at a statistic analysis with a larger number of participants. In the following, we briefly explain different kinds of evaluation. At most minor problems may be addressed in this late stage. Ongoing formative evaluation is essential for research projects where a large design space is explored [Buxton, 2007]. Most, if not all, rapid UX evaluation methods (Chapter 13) have only a formative UX evaluation component and do not have a summative component. Qualitative data are non-numeric and descriptive data, usually describing a UX problem or issue observed or experienced during usage. The goal is to assess whether the product or service meets standards or requirements. But informal summative evaluation may be less known as an important engineering tool in the HCI bag and that the only criterion for judging this kind of summative evaluation method is whether it works as part of an engineering process. This way, you can get a reaction to design changes from the previous cycle, in addition to a new set of data on the modified design from the two new participants. In addition, it’s expensive and time consuming to do a proper summative evaluation. It can apply to a range of aspects such as the individual’s degree of participation in learning activities, something which is of particular relevance in NCL. Common Types of Formative Evaluation. The user experience-related factors are integrated in evaluations, e.g., it is relevant to understand very good or very bad experiences users had with a system. Because we wish to invite these volunteers to join our team and help us evaluate designs (i.e., we want them to participate), we use the term “participant” instead of “subject” (Section 21.1.3). Julie Carpenter, in Project Management in Libraries, Archives and Museums, 2011, Depending on the focus, the expected outcome of a formative evaluation (for instance, a mid-term evaluation) is a decision taken to. Such summative evaluations have rarely been accomplished in medical visualization. Both approaches can examine how an intervention was implemented, the barriers and facilitators to implementation, and the effects of the intervention on various outcomes. Formative evaluation assists individuals in enhancing their performance and producing successful outcomes. One of the most frequently cited works on formative assessment is the research review conducted by Black and Wiliam in 1998. So you have to do the “driving”; it is too early for anyone else in a user role to engage in real interaction. Also called ex-post research. Structured conceptualization helps stakeholders define the program, the target population, and the possible outcomes. It used to frame the outcome of an investigative process, done at the end of the project. Even early lab-based tests can include walkthroughs (Bias, 1991). Kathy Baxter, ... Kelly Caine, in Understanding your Users (Second Edition), 2015. formative assessment to accomplish this. By the time you have constructed a low-fidelity prototype, a paper prototype, for example, UX inspection methods and lightweight quasi-empirical testing are appropriate. Table 18-1. The most in-depth inspection method is the cognitive walkthrough, where the whole user interface is analyzed [Polson et al., 1992, Blackmon et al., 2003]. Formative research is integral in developing programs as well as improving existing and ongoing programs.”. Our friend and colleague, George Casaday calls it: “Waffle Wisdom” or “Pancake Philosophy”—like the first waffle or pancake, you expect from the start to throw away the first design, and maybe the next few. Formative evaluations are accomplished with a few users in an informal way. If the whole team agrees that the old button label was vague and confusing and the new button label is clear and easily understood, then the team probably should make that design change. 21-2). A cute, but apropos, way to look at the difference: “When the cook tastes the soup, that's formative; when the guests taste the soup, that's summative” (Stake, 2004, p. 17). The goal of the design refinement iteration is to make modifications, or adjust details of, the ecological, interaction, and emotional designs in response to findings from the formative evaluation (UX evaluation for the purpose of finding and fixing UX problems and thereby refining the design, Chapter 21) activity. The original research base on formative assessment is most typically traced back to the 1998 publication Assessm ent and Classroom Learning (Black & Wiliam, 1998), the first widely cited review of literature on formative assessment in the English language. Although both components can provide feedback on the effectiveness of an intervention and offer ways to improve it, they differ in frequency, aim, and focus. Evaluation is a systematic process to understand what a program does Quantitative data are numeric data, such as user performance metrics or opinion ratings. Please log in from an authenticated institution or log into your member profile to access the email feature. Sometimes empirical lab-based UX testing that includes quantitative metrics is the source of controversy with respect to “validity.” Sometimes we hear “If you do not include formal summative evaluation, are you not missing an opportunity to add some science?” “Since your informal summative evaluation was not controlled testing, why should we not dismiss your results as too ‘soft’?” “Your informal studies just are not good science. Some differences between formal and informal summative UX evaluation methods. For medical visualizations, both kinds of evaluations are essential. It's all very well in practice but it will never work in theory. Needs assessment determines who needs the program, how great the need is, and what might work to meet the need. Because of the lack of statistical rigor, these results especially cannot be used to make any claims inside or outside the team. Preparation includes the selection of tasks to be performed and the selection of questions to be answered. Figure 12-2. If new technologies or input devices should be compared against those that are familiar to users, a careful preparation is necessary to compensate for the missing experience with new technology. Besides subjective assessments of users, physiological measures, such as pulse rates, indicating workload, in particular mental workload are increasingly used to understand how much attention different variants of user interfaces require [Saleem and Russ, 2009]. Unlike summative, formative testing can and should be done multiple times in a prod… An informal summative UX evaluation method is a quantitative summative UX evaluation method that is not statistically rigorous and does not produce statistically significant results. In many ways, engineering is about judgment based on hunches and intuition that are, in turn, based on skill and experience. In particular: the appropriateness of feedback, and as a more quantitative measure. Another basic distinction is between inspection-based and empirical evaluation. Evaluations are, in a broad sense, concerned with the effectiveness of programs. It could also regard the impact that newly developed competencies have on the individual’s professional life and workplace. Empirical methods such as testing with user participants can also be limited to a formative evaluation component, especially in early stages, when we are defining and refining the design and are not yet interested in performance indicators. Logging protocols, which represent the actions taken by the user, are often an invaluable help. Formative evaluation is the use of data before and/or during instruction or the implementation of an intervention. Black and Wiliam (1998) found that summative assessments had a much less powerful positive effect on student learning than formative assessment. In lab-based UX testing sessions we also often use only … Usually at this point in a project, you have only scenarios, storyboards, screen sketches, or, at most, a low-fidelity (non-interactive) prototype. Both strategies have advantages and disadvantages. Summative evaluation is about collecting quantitative data for assessing a level of quality due to a design, especially for assessing improvement in the user experience due to formative evaluation. A user uttered the system “reacted well to local changes without causing too much global deformation” and another one likes that “small localized scribbles only have a local effect.” For other techniques they explained that “adding one scribble may completely change the segmentation.” Thus, in particular issues of feeling in control and algorithm responsiveness may be analyzed by means of such verbal comments. Explore the research methods terrain, ... Formative evaluation is the use of data before and/or during instruction or the implementation of an intervention. Formative Assessment occurs on an on-going basis, either monthly or quarterly. There are a variety of evaluation designs, and the type of evaluation should match the development level of the program or program activity appropriately. The program stage and scope will determine the level of effort and the methods to be used. In summative research, you can determine whether a product is usable by some standard measure, such as number of errors or time on task. Example : “How are people’s lives (or communities, or animals, or the… However, informal summative evaluation is done without experimental controls, with smaller numbers of user participants, and with only summary descriptive statistics (such as average values). This takes special training and skills, so don’t promise summative evaluation if you can’t deliver. But sometimes reusing a participant (maybe one out of three to five) can make sense. Perhaps more well known is the follow-up usage by Dick and Carey (1978) in the area of instructional design. Formative and summative evaluations correspond to different research goals. As a consequence, more insights usually result from formative or informal summative evaluations where a few users are carefully observed and interrogated. Formative evaluation is how you find out how to make the next ones better and better. In Chapter 4, we got to know a large variety of segmentation techniques, most of them are semi-automatic and depend on interactive initialization, steering of parameters and correction of initial results. Of course you would not use a repeat participant for tasks addressing an “initial use” UX attribute. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Users are more critical and discuss more intensively if they may select between a few alternatives instead of having to comment on the only one solution presented to them. The goal of formative evaluation is to meet the specific needs of students by identifying those objectives that have and have not been mastered by the student and determining what needs to be taught, individualizing educational programs for all students. It looks at. Inspection-based evaluations are performed by usability experts, that is by persons with substantial experience in the design, development and evaluation of user interfaces [Nielsen and Mack, 1994]. A formative evaluation covers up a wide range of diagnostics that are required by the students or individuals. Evaluation is the process where prototypes or completed systems are carefully checked and evaluated either by users or usability experts. Perhaps more well known is the follow-up usage by Dick and Carey (1978) in the area of instructional design. Summative UX evaluation includes both formal and informal methods. In UX engineering, formative UX evaluation includes any method that meets the definition of helping to form the design. This may be due, in part, to the fact that the fields of HCI and UX were formed as a melting pot of people from widely varying backgrounds. One general recommendation is to let users compare alternatives. is part of the instructional process. While some aspects, such as general medical visualization techniques, might be assessed even by students in a reliable way, specialized techniques, such as those for bloodflow visualization, require highly specialized medical doctors. Summative evaluations are conducted once a product or service is complete. The most popular UX inspection method (Chapter 13) is the heuristic evaluation (HE) method. The research team measured the effects of formative assessment on learning outcomes and found a mean effect size of 0.32 when exposed to the intervention. It has to be carefully thought how many test persons are actually needed (often a small number is sufficient to identify most of the problems), whether medical doctors are needed for all aspects of an evaluation, and what particular experience the users need to have. Formative Evaluations In early stages, sketches and mockups may be used. In lab-based UX testing sessions we also often use only formative evaluation, especially in early cycles of iteration when we are defining and refining the design and are not yet interested in performance numbers. A well-defined task analysis is essential, since workflows and scenarios determined in this stage provide a useful guidance for an evaluation. Evaluations might be applied in more artificial settings, e.g., in the office of a developer or even a user interface lab with dedicated facilities to record user actions. The feedback is the main parameter which enables students to reflect what they are learning and know the reason for the same. Although research has clearly shown that formative assessment can enhance student success, there is firm evidence of a research-practice divide. For industrial projects, it is mandatory to collect and analyze this kind of feedback. The following key issues should be considered to ensure good feedback and subsequent use and integration of evaluation findings in future project implementation, programming or policy change: Evaluation as a consultative process: ensuring the participation of relevant stakeholders, enhancing ownership of the evaluation and its results. HCI researchers make a basic distinction between formative and summative evaluations. They are a natural part of any iterative user-centered design process. The term “formal” is used because the process is statistically rigorous. Evaluation methods such as design reviews, heuristic methods, and other UX inspection methods are good examples of purely formative evaluation methods (without a summative component). Evaluations are useless unless they are used. Project managers are responsible for keeping the project board, partners and other closely involved stakeholders appropriately informed on progress at each key stage of the evaluation. These questions ignore the fundamental difference between formal and informal summative evaluation and the fact that they have completely different goals and methods. When incorporated into classroom practice, it provides the information needed to adjust teaching and learning while they are happening. Thus, usability experts without any experience in medical applications can only detect a subset of the real usability problems, based on their general know-how of menus, dialog and form design or web usability. Formative evaluations are carried out during the development and serve to receive feedback for guiding the further development. Formative evaluations are conducted during product development or as a product is still being formed. A comprehensive program evaluation ideally includes both formative and summative components. In formative research, you can figure out what participants think about a topic, determine when a feature is not working well and why, and suggest changes based on those findings. Formative evaluations improve a product's quality through the ongoing process of gathering data, making revisions, and then gathering data about the revisions (Beyer, 1995). Instead, both may be used complementarily, e.g., a heuristic evaluation prior to an empirical evaluation in order to remove obvious flaws. Summative evaluations characterize the final system with respect to: Moreover, other usability factors, e.g., related to user satisfaction, are essential. By continuing you agree to the use of cookies. Formative evaluations stress engagement with stakeholders when the interv… Formative Assessment is an assessment for learning, whereas summative Assessment is an assessment of learning. This discussion comprises evaluations carried out at different stages in the development process and evaluations, performed either by asking user interface experts or by testing with potential users. We call this combination “UX engineering evaluation” or just “UX evaluation,” as shown in Figure 12-2. Unlike most participants in lab-based testing, an expert will be broadly knowledgeable in the area of interaction design guidelines and will have extensive experience in evaluating a wide variety of interaction styles. They can be conducted during any phase of the ADDIEprocess. Medical applications have a lot of peculiarities. A formal summative (quantitative) UX evaluation method is an empirical method that produces statistically significant results. Summative assessment receives much less attention in literature and research than formative assessment. Formative assessment is different from summative assessment, the goal of which is to measure mastery. Many aspects of such an evaluation need to be carefully considered, such as the selection of test persons, the specific questionnaire design and the statistical methods used for evaluation. A participant, or user participant, is a user, potential, or user surrogate who helps evaluate UX designs for usability and user experience. What Is Formative Assessment? You cannot draw any conclusions.”. We address those questions and more in Chapter 17, evaluation reporting. For medical visualizations, both kinds of evaluations are carried out during the development implementation.

Summative evaluation involves making judgments about the efficacy of a program or course at its conclusion. Also, sometimes the term is used to refer to a more comprehensive team evaluation, more like a team-based UX inspection. Evaluation Types When to use What it shows Why it is useful Formative Evaluation Evaluability Assessment The selection of test persons is another serious aspect. The analysis compiled over 250 publications, both quantitative and qualitative, which were found to: Evaluation is the process of examining a program, procedure, or product to estimate its function, effect, and worth. Alpha and beta testing with selected users and/or customers are appropriate evaluation methods for pre-release versions of the near-final product. Thus, formative evaluations are basically done on the fly. CHAPTER 4 Guidelines for Formative Evaluation Research in Campaign Design 55 designer. Copy and paste the following HTML into your website. Calling on a previously used participant tells them you value their help and gives them a kind of empowerment, a feeling that they are helping to make a difference in your design. It is done early with simulations and early working prototypes of designs and explores whether usability objectives are obtainable or not. This method measures change in knowledge, attitudes and behaviors of the subject. From their own far-flung cultures in psychology, human factors engineering, systems engineering, software engineering, marketing, and management they arrived at the docks of HCI with their baggage containing their own perspectives and mind-sets. The “think aloud” technique, like in early task analysis, is helpful. Guglielmo Trentin, in Networked Collaborative Learning, 2010. Perhaps the most important basic distinction in evaluation types is that between formative and summativeevaluation. Such a comparison, of course, includes validation (recall § 4.7) where the accuracy of the results related to some ground truth is determined with various distance and volume overlap metrics.

In medical visualization, typical tasks include the description of the morphology and spatial surrounding of a pathology, its classification and the assessment of its operability. Thus the reason for iteration and refinement cycles, to which evaluation is central. In sum, formal summative evaluation is an important HCI research skill, but in our view it is not part of UX practice. Identify needs. Formative Assessment Writing Activities and Research Activities Formative Assessment Activities Definition Classroom Options Writing Break Stop in the middle of class and give students two minutes to write about the lesson or topic. Finally, you can continue to evaluate a system or product even after deployment in the field via remote surveys and/or questionnaires and remote UX evaluation, a method that has the advantage of operating within the context of real-world usage. Calling on a previously used participant tells them you value their help and gives them a kind of empowerment, a feeling that they are helping to make a difference in your design. The evaluation results need to be disseminated e.g. In a similar way, a user interface is analyzed in usability inspection with respect to conformance to styleguides and potential usability problems. FERA clients include foundations and their grantees, nonprofit organizations, strategic alliances and collaborative efforts, and networks/membership associations at the local, national, and international levels. At the end of each iteration for a product version, the informal summative evaluation is used as a kind of acceptance test to compare with our UX targets and ensure that we meet our UX and business goals with the product design. Formative evaluation may focus on attainment of intermediate goals and reveal whether a certain participant has acquired given knowledge/skills. To accomplish this goal, the brief defines formative assessment, examines the research, and outlines the components needed to develop a high-quality, research-based formative assessment plan in a state, district, or school . A usability expert with background in medicine instead may also suggest alternative solutions for special tasks based on his knowledge of competing products or related projects. In general, formative usability evaluation is done to find and fix problems with an existing product in order to make it more usable. Summative Evaluation often aims at a statistic analysis with a larger number of participants. In the following, we briefly explain different kinds of evaluation. At most minor problems may be addressed in this late stage. Ongoing formative evaluation is essential for research projects where a large design space is explored [Buxton, 2007]. Most, if not all, rapid UX evaluation methods (Chapter 13) have only a formative UX evaluation component and do not have a summative component. Qualitative data are non-numeric and descriptive data, usually describing a UX problem or issue observed or experienced during usage. The goal is to assess whether the product or service meets standards or requirements. But informal summative evaluation may be less known as an important engineering tool in the HCI bag and that the only criterion for judging this kind of summative evaluation method is whether it works as part of an engineering process. This way, you can get a reaction to design changes from the previous cycle, in addition to a new set of data on the modified design from the two new participants. In addition, it’s expensive and time consuming to do a proper summative evaluation. It can apply to a range of aspects such as the individual’s degree of participation in learning activities, something which is of particular relevance in NCL. Common Types of Formative Evaluation. The user experience-related factors are integrated in evaluations, e.g., it is relevant to understand very good or very bad experiences users had with a system. Because we wish to invite these volunteers to join our team and help us evaluate designs (i.e., we want them to participate), we use the term “participant” instead of “subject” (Section 21.1.3). Julie Carpenter, in Project Management in Libraries, Archives and Museums, 2011, Depending on the focus, the expected outcome of a formative evaluation (for instance, a mid-term evaluation) is a decision taken to. Such summative evaluations have rarely been accomplished in medical visualization. Both approaches can examine how an intervention was implemented, the barriers and facilitators to implementation, and the effects of the intervention on various outcomes. Formative evaluation assists individuals in enhancing their performance and producing successful outcomes. One of the most frequently cited works on formative assessment is the research review conducted by Black and Wiliam in 1998. So you have to do the “driving”; it is too early for anyone else in a user role to engage in real interaction. Also called ex-post research. Structured conceptualization helps stakeholders define the program, the target population, and the possible outcomes. It used to frame the outcome of an investigative process, done at the end of the project. Even early lab-based tests can include walkthroughs (Bias, 1991). Kathy Baxter, ... Kelly Caine, in Understanding your Users (Second Edition), 2015. formative assessment to accomplish this. By the time you have constructed a low-fidelity prototype, a paper prototype, for example, UX inspection methods and lightweight quasi-empirical testing are appropriate. Table 18-1. The most in-depth inspection method is the cognitive walkthrough, where the whole user interface is analyzed [Polson et al., 1992, Blackmon et al., 2003]. Formative research is integral in developing programs as well as improving existing and ongoing programs.”. Our friend and colleague, George Casaday calls it: “Waffle Wisdom” or “Pancake Philosophy”—like the first waffle or pancake, you expect from the start to throw away the first design, and maybe the next few. Formative evaluations are accomplished with a few users in an informal way. If the whole team agrees that the old button label was vague and confusing and the new button label is clear and easily understood, then the team probably should make that design change. 21-2). A cute, but apropos, way to look at the difference: “When the cook tastes the soup, that's formative; when the guests taste the soup, that's summative” (Stake, 2004, p. 17). The goal of the design refinement iteration is to make modifications, or adjust details of, the ecological, interaction, and emotional designs in response to findings from the formative evaluation (UX evaluation for the purpose of finding and fixing UX problems and thereby refining the design, Chapter 21) activity. The original research base on formative assessment is most typically traced back to the 1998 publication Assessm ent and Classroom Learning (Black & Wiliam, 1998), the first widely cited review of literature on formative assessment in the English language. Although both components can provide feedback on the effectiveness of an intervention and offer ways to improve it, they differ in frequency, aim, and focus. Evaluation is a systematic process to understand what a program does Quantitative data are numeric data, such as user performance metrics or opinion ratings. Please log in from an authenticated institution or log into your member profile to access the email feature. Sometimes empirical lab-based UX testing that includes quantitative metrics is the source of controversy with respect to “validity.” Sometimes we hear “If you do not include formal summative evaluation, are you not missing an opportunity to add some science?” “Since your informal summative evaluation was not controlled testing, why should we not dismiss your results as too ‘soft’?” “Your informal studies just are not good science. Some differences between formal and informal summative UX evaluation methods. For medical visualizations, both kinds of evaluations are essential. It's all very well in practice but it will never work in theory. Needs assessment determines who needs the program, how great the need is, and what might work to meet the need. Because of the lack of statistical rigor, these results especially cannot be used to make any claims inside or outside the team. Preparation includes the selection of tasks to be performed and the selection of questions to be answered. Figure 12-2. If new technologies or input devices should be compared against those that are familiar to users, a careful preparation is necessary to compensate for the missing experience with new technology. Besides subjective assessments of users, physiological measures, such as pulse rates, indicating workload, in particular mental workload are increasingly used to understand how much attention different variants of user interfaces require [Saleem and Russ, 2009]. Unlike summative, formative testing can and should be done multiple times in a prod… An informal summative UX evaluation method is a quantitative summative UX evaluation method that is not statistically rigorous and does not produce statistically significant results. In many ways, engineering is about judgment based on hunches and intuition that are, in turn, based on skill and experience. In particular: the appropriateness of feedback, and as a more quantitative measure. Another basic distinction is between inspection-based and empirical evaluation. Evaluations are, in a broad sense, concerned with the effectiveness of programs. It could also regard the impact that newly developed competencies have on the individual’s professional life and workplace. Empirical methods such as testing with user participants can also be limited to a formative evaluation component, especially in early stages, when we are defining and refining the design and are not yet interested in performance indicators. Logging protocols, which represent the actions taken by the user, are often an invaluable help. Formative evaluation is the use of data before and/or during instruction or the implementation of an intervention. Black and Wiliam (1998) found that summative assessments had a much less powerful positive effect on student learning than formative assessment. In lab-based UX testing sessions we also often use only … Usually at this point in a project, you have only scenarios, storyboards, screen sketches, or, at most, a low-fidelity (non-interactive) prototype. Both strategies have advantages and disadvantages. Summative evaluation is about collecting quantitative data for assessing a level of quality due to a design, especially for assessing improvement in the user experience due to formative evaluation. A user uttered the system “reacted well to local changes without causing too much global deformation” and another one likes that “small localized scribbles only have a local effect.” For other techniques they explained that “adding one scribble may completely change the segmentation.” Thus, in particular issues of feeling in control and algorithm responsiveness may be analyzed by means of such verbal comments. Explore the research methods terrain, ... Formative evaluation is the use of data before and/or during instruction or the implementation of an intervention. Formative Assessment occurs on an on-going basis, either monthly or quarterly. There are a variety of evaluation designs, and the type of evaluation should match the development level of the program or program activity appropriately. The program stage and scope will determine the level of effort and the methods to be used. In summative research, you can determine whether a product is usable by some standard measure, such as number of errors or time on task. Example : “How are people’s lives (or communities, or animals, or the… However, informal summative evaluation is done without experimental controls, with smaller numbers of user participants, and with only summary descriptive statistics (such as average values). This takes special training and skills, so don’t promise summative evaluation if you can’t deliver. But sometimes reusing a participant (maybe one out of three to five) can make sense. Perhaps more well known is the follow-up usage by Dick and Carey (1978) in the area of instructional design. Formative and summative evaluations correspond to different research goals. As a consequence, more insights usually result from formative or informal summative evaluations where a few users are carefully observed and interrogated. Formative evaluation is how you find out how to make the next ones better and better. In Chapter 4, we got to know a large variety of segmentation techniques, most of them are semi-automatic and depend on interactive initialization, steering of parameters and correction of initial results. Of course you would not use a repeat participant for tasks addressing an “initial use” UX attribute. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Users are more critical and discuss more intensively if they may select between a few alternatives instead of having to comment on the only one solution presented to them. The goal of formative evaluation is to meet the specific needs of students by identifying those objectives that have and have not been mastered by the student and determining what needs to be taught, individualizing educational programs for all students. It looks at. Inspection-based evaluations are performed by usability experts, that is by persons with substantial experience in the design, development and evaluation of user interfaces [Nielsen and Mack, 1994]. A formative evaluation covers up a wide range of diagnostics that are required by the students or individuals. Evaluation is the process where prototypes or completed systems are carefully checked and evaluated either by users or usability experts. Perhaps more well known is the follow-up usage by Dick and Carey (1978) in the area of instructional design. Summative UX evaluation includes both formal and informal methods. In UX engineering, formative UX evaluation includes any method that meets the definition of helping to form the design. This may be due, in part, to the fact that the fields of HCI and UX were formed as a melting pot of people from widely varying backgrounds. One general recommendation is to let users compare alternatives. is part of the instructional process. While some aspects, such as general medical visualization techniques, might be assessed even by students in a reliable way, specialized techniques, such as those for bloodflow visualization, require highly specialized medical doctors. Summative evaluations are conducted once a product or service is complete. The most popular UX inspection method (Chapter 13) is the heuristic evaluation (HE) method. The research team measured the effects of formative assessment on learning outcomes and found a mean effect size of 0.32 when exposed to the intervention. It has to be carefully thought how many test persons are actually needed (often a small number is sufficient to identify most of the problems), whether medical doctors are needed for all aspects of an evaluation, and what particular experience the users need to have. Formative Evaluations In early stages, sketches and mockups may be used. In lab-based UX testing sessions we also often use only formative evaluation, especially in early cycles of iteration when we are defining and refining the design and are not yet interested in performance numbers. A well-defined task analysis is essential, since workflows and scenarios determined in this stage provide a useful guidance for an evaluation. Evaluations might be applied in more artificial settings, e.g., in the office of a developer or even a user interface lab with dedicated facilities to record user actions. The feedback is the main parameter which enables students to reflect what they are learning and know the reason for the same. Although research has clearly shown that formative assessment can enhance student success, there is firm evidence of a research-practice divide. For industrial projects, it is mandatory to collect and analyze this kind of feedback. The following key issues should be considered to ensure good feedback and subsequent use and integration of evaluation findings in future project implementation, programming or policy change: Evaluation as a consultative process: ensuring the participation of relevant stakeholders, enhancing ownership of the evaluation and its results. HCI researchers make a basic distinction between formative and summative evaluations. They are a natural part of any iterative user-centered design process. The term “formal” is used because the process is statistically rigorous. Evaluation methods such as design reviews, heuristic methods, and other UX inspection methods are good examples of purely formative evaluation methods (without a summative component). Evaluations are useless unless they are used. Project managers are responsible for keeping the project board, partners and other closely involved stakeholders appropriately informed on progress at each key stage of the evaluation. These questions ignore the fundamental difference between formal and informal summative evaluation and the fact that they have completely different goals and methods. When incorporated into classroom practice, it provides the information needed to adjust teaching and learning while they are happening. Thus, usability experts without any experience in medical applications can only detect a subset of the real usability problems, based on their general know-how of menus, dialog and form design or web usability. Formative evaluations are carried out during the development and serve to receive feedback for guiding the further development. Formative evaluations are conducted during product development or as a product is still being formed. A comprehensive program evaluation ideally includes both formative and summative components. In formative research, you can figure out what participants think about a topic, determine when a feature is not working well and why, and suggest changes based on those findings. Formative evaluations improve a product's quality through the ongoing process of gathering data, making revisions, and then gathering data about the revisions (Beyer, 1995). Instead, both may be used complementarily, e.g., a heuristic evaluation prior to an empirical evaluation in order to remove obvious flaws. Summative evaluations characterize the final system with respect to: Moreover, other usability factors, e.g., related to user satisfaction, are essential. By continuing you agree to the use of cookies. Formative evaluations stress engagement with stakeholders when the interv… Formative Assessment is an assessment for learning, whereas summative Assessment is an assessment of learning. This discussion comprises evaluations carried out at different stages in the development process and evaluations, performed either by asking user interface experts or by testing with potential users. We call this combination “UX engineering evaluation” or just “UX evaluation,” as shown in Figure 12-2. Unlike most participants in lab-based testing, an expert will be broadly knowledgeable in the area of interaction design guidelines and will have extensive experience in evaluating a wide variety of interaction styles. They can be conducted during any phase of the ADDIEprocess. Medical applications have a lot of peculiarities. A formal summative (quantitative) UX evaluation method is an empirical method that produces statistically significant results. Summative assessment receives much less attention in literature and research than formative assessment. Formative assessment is different from summative assessment, the goal of which is to measure mastery. Many aspects of such an evaluation need to be carefully considered, such as the selection of test persons, the specific questionnaire design and the statistical methods used for evaluation. A participant, or user participant, is a user, potential, or user surrogate who helps evaluate UX designs for usability and user experience. What Is Formative Assessment? You cannot draw any conclusions.”. We address those questions and more in Chapter 17, evaluation reporting. For medical visualizations, both kinds of evaluations are carried out during the development implementation.
