Medical students' cognitive load in volumetric image interpretation:Insights from human-computer interaction and eye movements

Medical image interpretation is moving from using 2D- to volumetric images, thereby changing the cognitive and perceptual processes involved. This is expected to affect medical students' experienced cognitive load, while learning image interpretation skills. With two studies this explorative research investigated whether measures inherent to image interpretation, i.e. human-computer interaction and eye tracking, relate to cognitive load. Subsequently, it investigated effects of volumetric image interpretation on second-year medical students' cognitive load. Study 1 measured human-computer interactions of participants during two volumetric image interpretation tasks. Using structural equation modelling, the latent variable 'volumetric image information' was identified from the data, which significantly predicted self-reported mental effort as a measure of cognitive load. Study 2 measured participants' eye movements during multiple 2D and volumetric image interpretation tasks. Multilevel analysis showed that time to locate a relevant structure in an image was significantly related to pupil dilation, as a proxy for cognitive load. It is discussed how combining human-computer interaction and eye tracking allows for comprehensive measurement of cognitive load. Combining such measures in a single model would allow for disentangling unique sources of cognitive load, leading to recommendations for implementation of volumetric image interpretation in the medical education curriculum

The development of research supervisors’ pedagogical content knowledge in a lesson study project

In this study, we aimed to identify how the learning activities elicited in a lesson study project contributed to self-perceived change in supervisors’ pedagogical content knowledge (PCK). Lesson study is a method which combines both professional and educational development. During a lesson study project, teachers collaborate in a team and develop, teach, evaluate, and redesign a research lesson. During the 4-month lesson study project described here, four supervisors designed a protocol for research supervision meetings aimed at enhancing undergraduate students’ learning. During the project, they experimented with open questioning and giving positive feedback instead of giving instruction and explanations. A mixed-methods design was used in this study. Data on the supervisors’ learning activities and PCK were gathered using learner reports, video-recordings of meetings, and exit interviews. The analyses of these data showed that the lesson study project contributed to the development of the supervisors’ PCK on instructional strategies and student understanding. The learning activity that contributed most to these changes was reflecting on their own practice and that of their students

Connecting academics’ disciplinary knowledge to their professional development as university teachers: a conceptual analysis of teacher expertise and teacher knowledge

Disciplinary knowledge lies at the heart of academic work. However, connecting academics’ disciplinary knowledge to their professional development as teachers has been a longstanding challenge for (research-intensive) universities. This is reflected in criticism of the practices that aim to support the professional development of university teachers. In order to create better connections, a deeper understanding is needed of how academics’ disciplinary knowledge relates to the development of their teaching. In this paper, we therefore aim to advance theoretical insights about how academics’ disciplinary knowledge connects to their professional development as university teachers. We do so by providing a conceptual analysis of teacher expertise and teacher knowledge perspectives. Literature discussed as part of the teacher expertise perspective provides insights into how knowledge is structured in order to perform teacher tasks. In our discussion of the teacher knowledge perspective, we include bodies of literature about teachers’ knowledge base to explore the role of disciplinary knowledge in how to teach and about powerful knowledge to explore the role of disciplinary knowledge in what to teach. Insights from these bodies of literature can, from a teacher knowledge perspective, offer theoretical underpinnings for connecting academics’ disciplinary knowledge to their professional development as university teachers. Adaptive expertise and practical knowledge are identified as concepts that include elements of both teacher expertise and teacher knowledge perspectives. Based on the conceptual analysis, we identify and discuss three aspects related to supporting the professional development of university teachers where attention to connection with teachers’ disciplinary knowledge is important

Between theory and practice: educators’ perceptions on assessment quality criteria and its impact on student learning

Introduction: The shift toward an assessment for learning culture includes assessment quality criteria that emphasise the learning process, such as transparency and learning impact, in addition to the traditional validity and reliability criteria. In practice, the quality of the assessment depends on how the criteria are interpreted and applied. We explored how educators perceive and achieve assessment quality, as well as how they perceive assessment impact upon student learning. Methods: We employed a qualitative research approach and conducted semi-structured interviews with 37 educators at one Dutch research university. The data were subsequently analysed using a template analysis. Results: The findings indicate that educators predominantly perceive and achieve assessment quality through traditional criteria. The sampled curricular stakeholders largely perceived assessment quality at the course level, whilst few specified programme-level quality criteria. Furthermore, educators perceived the impact of assessment on student learning in two distinct ways: as a source of information to monitor and direct student learning, and as a tool to prompt student learning. Discussion: The shift toward a culture of assessment for learning is not entirely reflected in educators’ current perceptions. The study’s findings set the stage for better assessment quality and alignment with an assessment for learning culture

For Your Eyes Only? The Use of Surgical Videos in Urological Residency Training: A European-wide Survey

Background and objective: Video-based learning may be beneficial in surgical education, both in the preparation for surgery and to evaluate surgical performance. The use of a video is not yet anchored in European urology residency programs, and it is unclear how frequently residents use videos. The purpose of this study is to investigate whether and how urology residents utilize videos to prepare for surgical procedures and evaluate their surgical performance. Methods: We conducted a European-wide, survey-based, needs assessment among urology residents. The survey was distributed electronically among the participants in the European Urology Residents Education Program 2022 and all the members of the European Society of Residents in Urology. Key findings and limitations: Seventy-two surveys were completed by the residents of 12 nationalities. Of the residents, 98.6% used videos in preparation, mainly for open, laparoscopic, and robotic procedures. YouTube was by far the most used source. Of the residents, 86% believed that a postsurgical video review would be helpful. In total, 39% of the residents actually had this possibility. Of them, 30% had the opportunity to do this together with a supervisor. Conclusions and clinical implications: This study demonstrated that European urology residents often use videos to prepare surgical procedures. Considering that the majority of the respondents use YouTube as the main source of videos, this seems not to be formalized within their training. Although most residents would value a postsurgical video review, preferably together with a supervisor, the latter is not available to the majority. We recommend the use of professional, and not public, video channels and easier access to postsurgical video review. Patient summary: Video-based learning may have an important role in surgical education. Videos often are a source of education for European urology residents to prepare for surgical procedures. Although most residents would appreciate a postsurgical video review or video-based coaching, this is not available to the majority of them

Medical Students' General Beliefs and Specific Perceptions about Patient Feedback Before and after Training in a Clinical Context

INTRODUCTION: Despite its high potential, patient feedback does not always result in learning. For feedback to be effective students must engage with it, which partly depends on their perceptions of feedback. To better understand student engagement with patient feedback in a clinical context, this study explored the following research questions: 1) What are medical students' general beliefs about patient feedback and what are their specific perceptions of feedback messages? 2) What is the difference between these general beliefs and feedback message perceptions before and after patient feedback training? METHODS: The study context was a 12-week clerkship combining Pediatrics and Gynecology, which included feedback training for students and asking for patient feedback. Ninety 4th-year medical students completed pre- and post-clerkship questionnaires. The questionnaires (Beliefs about Patient Feedback Questionnaire, Feedback Perception Questionnaire) were adapted from validated peer-feedback questionnaires. Questionnaires were quantitatively analyzed. RESULTS: Both pre- and post-clerkship, students had positive general beliefs about patient feedback and positive perceptions of the feedback messages they received. However, paired t-tests showed that students' general beliefs and feedback message perceptions became less positive after feedback training and experience. DISCUSSION: Patient feedback is not an easy means to learn and students do not become feedback literate in terms of patient feedback overnight. We suggest that future researchers further explore reasons for the decline in positive perceptions of patient feedback. We suggest implementing longitudinal feedback training in medical curricula, where students are guided and supported in the complex task of learning from patients through feedback

AIDS awareness and VCT behaviour: An application of the integrated model of behaviour prediction

In order to limit the expansion of the HIV and AIDS epidemic in South Africa, it is important to develop targeted prevention strategies. The voluntary HIV counselling and testing (VCT) programme appears to be effective for preventing the spread of the HI virus. This study adapted guidelines of the integrated model of behaviour prediction (IMBP) into a questionnaire and examined the extent to which it predicts behaviour. A sample of 92 sports team members from Limpopo ranging from 14 to 30 years of age completed the questionnaire. Results suggested that beliefs about the outcomes of behaviour and beliefs about the expectations of others had a direct influence on the intention to undergo HIV counselling and testing. Efficacy beliefs, namely beliefs that there are factors that can facilitate behaviour, can lead to actual testing behaviour if accompanied by self-efficacy. Knowledge, intention and stigma are not related to VCT behaviour. Findings show that some constructs influence intention and test behaviour, but in ways not predicted by the model. Thus, the adequacy of the IMBP to determine HIV and AIDS-preventative behavioural intentions is questioned

A scoping review on the notions of Assessment as Learning (AaL), Assessment for Learning (AfL), and Assessment of Learning (AoL)

Associations between assessment and learning are widely studied and often organized around the notions of Assessment as Learning (AaL), Assessment for Learning (AfL), and Assessment of Learning (AoL). Although these notions are appealing in theory, the notions are unclear constructs to comprehend, as both their definitions and their practice are used inconsistently in educational research. We present a synthesis of common characteristics among these notions, based on a scoping review on definitions and descriptions of AaL, AfL, and AoL (131 studies). The synthesis of common characteristics consists of nine themes that refer to how educational assessment relates to learning. The themes are grouped into: 1) Student-teacher roles and relationships within assessment; 2) Assessment learning environment; and 3) Educational outcomes of assessment. Then, we used the themes within the synthesis to analyze the results of the included empirical studies on their contributions to practice (84 studies). The synthesis provides stakeholders with a clear and integrative view of how educational assessment relates to learning and may be beneficial to educators to support and design their assessment practices. We argue that the notions of AaL, AfL, and AoL should be seen in coherence with one another in order to establish an assessment culture that facilitates students’ learning maximally
