Understanding and developing procedures for video-based assessment in medical education.

INTRODUCTION: Novel uses of video aim to enhance assessment in health-professionals education. Whilst these uses presume equivalence between video and live scoring, some research suggests that poorly understood variations could challenge validity. We aimed to understand examiners' and students' interaction with video whilst developing procedures to promote its optimal use. METHODS: Using design-based research we developed theory and procedures for video use in assessment, iteratively adapting conditions across simulated OSCE stations. We explored examiners' and students' perceptions using think-aloud, interviews and focus group. Data were analysed using constructivist grounded-theory methods. RESULTS: Video-based assessment produced detachment and reduced volitional control for examiners. Examiners ability to make valid video-based judgements was mediated by the interaction of station content and specifically selected filming parameters. Examiners displayed several judgemental tendencies which helped them manage videos' limitations but could also bias judgements in some circumstances. Students rarely found carefully-placed cameras intrusive and considered filming acceptable if adequately justified. DISCUSSION: Successful use of video-based assessment relies on balancing the need to ensure station-specific information adequacy; avoiding disruptive intrusion; and the degree of justification provided by video's educational purpose. Video has the potential to enhance assessment validity and students' learning when an appropriate balance is achieved.

Comparing the influence of 'describing findings to the examiner' or 'examining as in usual practice' on the students' performance and assessors' judgements during physical examination skills assessment.

This article was migrated. The article was marked as recommended. BACKGROUND: Within assessment of physical examination skills, two approaches are common: "Describing Findings" (students comment throughout); and examining as "Usual Practice" (students only report findings at the end). Despite numerous potential influences on both students' performances and assessors' judgements, no prior studies have investigated the influence of either approach on assessments. METHODS: Two group, randomised, crossover design. Within a 2-station simulated physical examination OSCE, we manipulated whether students "described findings" or examined as "usual practice", collecting 1/. performance scores; 2/. Students'/examiners' cognitive load ratings; ratings of the 3/. fluency and 4/. completeness of students' presentations and 5/. Students' task-finishing, comparing all 5 end-points across conditions. RESULTS: Neither students' performance scores nor examiners' cognitive load were influenced by experimental condition. Students reported higher cognitive load (7/9) when "describing findings" than "usual practice" (6/9, p=0.002), and were less likely to finish (4 vs 12, p=0.007). Presentation completeness was higher for "describing findings" (mean=2.40, (95CIs=2.05-2.74)) than "usual practice" (mean=1.92 (1.65-2.18),p=0.016), whilst fluency ratings showed a similar trend. CONCLUSIONS: The decision to "Describe Findings" or examine as "Usual Practice" does not appear neutral, potentially influencing students' efficiency, recall and (by inference) learning. Institutions should explicitly select one option based on assessment goals.

Utility of an app-based system to improve feedback following workplace-based assessment.

OBJECTIVES: To determine whether an app-based software system to support production and storage of assessment feedback summaries makes workplace-based assessment easier for clinical tutors and enhances the educational impact on medical students. METHODS: We monitored our workplace assessor app's usage by Year 3 to 5 medical students in 2014-15 and conducted focus groups with Year 4 medical students and interviews with clinical tutors who had used the apps. Analysis was by constant comparison using a framework based on elements of van der Vleuten's utility index. RESULTS: The app may enhance the content of feedback for students. Using a screen may be distracting if the app is used during feedback discussions.    Educational impact was reduced by students' perceptions that an easy-to-produce feedback summary is less valuable than one requiring more tutor time and effort. Tutors' typing, dictation skills and their familiarity with mobile devices varied. This influenced their willingness to use the assessment and feedback mobile app rather than the equivalent web app. Electronic feedback summaries had more real and perceived uses than anticipated both for tutors and students including perceptions that they were for the school rather than the student. CONCLUSIONS: Electronic workplace-based assessment systems can be acceptable to tutors and can make giving detailed written feedback more practical but can interrupt the social interaction required for the feedback conversation. Tutor training and flexible systems will be required to minimise unwanted consequences. The educational impact on both tutors and students of providing pre-formulated advice within the app is worth further study.

Does formal workplace based assessment add value to informal feedback?

This article was migrated. The article was marked as recommended. Feedback is a key component of learning but effective feedback is a complex process with many aspects. One aspect may be a written summary which is passed to the learner but this may not be valued by learners. We examined the role of written feedback in the feedback process to determine whether it does more than provide a simple summary of the interaction. We conducted a secondary analysis of data gathered for a study of formative workplace based assessment. Interview data from 24 interviews with students and written summaries of workplace based assessments for 23 of them were reanalysed by two researchers who were already immersed in the data and examined all references to verbal, informal feedback and written, formal feedback or the assessment tool used. We found that students valued the verbal feedback discussion highly and that they often considered the written summaries superfluous. We also found that the act of preparing written feedback augmented the feedback discussion and tutors had adopted the language of the formal instrument in the verbal feedback and free text written feedback. What this study adds to existing research is evidence that there may be a secondary faculty development effect of requiring the preparation of written feedback which has served to enhance the educational content of feedback. Although this is not proof of causality (the requirement to provide written feedback alone producing the positive effects), we consider that the likelihood is sufficiently strong to continue the practice.

Grades in formative workplace-based assessment: a study of what works for whom and why.

CONTEXT: Grades are commonly used in formative workplace-based assessment (WBA) in medical education and training, but may draw attention away from feedback about the task. A dilemma arises because the self-regulatory focus of a trainee must include self-awareness relative to agreed standards, which implies grading. OBJECTIVES: In this study we aimed to understand the meaning which medical students construct from WBA feedback with and without grades, and what influences this. METHODS: Year 3 students were invited to take part in a randomised crossover study in which each student served as his or her own control. Each student undertook one WBA with and one without grades, and then chose whether or not to be given grades in a third WBA. These preferences were explored in semi-structured interviews. A realist approach to analysis was used to gain understanding of student preferences and the impact of feedback with and without grades. RESULTS: Of 83 students who were given feedback with and without grades, 65 (78%) then chose to have feedback with grades and 18 (22%) without grades in their third WBA. A total of 24 students were interviewed. Students described how grades locate their performance and calibrate their self-assessment. For some, low grades focused attention and effort. Satisfactory and high grades enhanced self-efficacy. CONCLUSIONS: Grades are concrete, powerful and blunt, can be harmful and need to be explained to help students create helpful meaning from them. Low grades risk reducing self-efficacy in some and may encourage others to focus on proving their ability rather than on improvement. A metaphor of the semi-permeable membrane is introduced to elucidate how students reduced potential negative effects and enhanced the positive effects of feedback with grades by selective filtering and pumping. This study illuminates the complexity of the processing of feedback by its recipients, and informs the use of grading in the provision of more effective, tailored feedback.
