Anatomy practical examinations: How does student performance on computerized evaluation compare with the traditional format?

Practical examinations in anatomy are usually conducted on specimens in the anatomy laboratory (referred to here as the “traditional” method). Recently, we have started to administer similar examinations online using the quiz facility in Moodle?. In this study, we compare student scores between two assessment environments viz. online and traditional environments. We hypothesized that regardless of the examination medium (traditional or online) overall student performance would not be significantly different. For the online medium, radiological images, prosected specimens, and short video clips demonstrating muscle action were first acquired from resources used for teaching during anatomy practical classes. These were optimized for online viewing and then uploaded onto Moodle learning management software. With regards to the traditional format, actual specimens were usually laid out in a circular stream. Identification tags were then attached to specific spots on the specimens and questions asked regarding those identified spots. A cohort of students taking practical examinations in six courses was studied. The courses were divided into three pairs with each pair credit‐weight matched. Each pair consisted of a course where the practical examination was conducted online and the other in the traditional format. There was no significant difference in the mean scores within each course pair. In addition, a significant positive correlation between score in traditional and online formats was found. We conclude that mean grades in anatomy practical examination conducted either online or in the traditional format were comparable. These findings should reassure teachers intending to use either format for their practical examinations. Anat Sci Educ. © 2011 American Association of Anatomists.

Conditions affecting the usefulness of pre- and post-tests for assessment purposes

Interest in measuring and evaluating student learning in higher education is growing. There are many tools available to assess student learning. However, the use of such tools may be more or less appropriate under various conditions. This study provides some evidence related to the appropriate use of pre/post‐tests. The question of whether graded tests elicit a higher level of performance (better representation of actual learning gains) than ungraded post‐tests is examined. We examine whether the difficulty level of the questions asked (knowledge/comprehension vs. analysis/application) affects this difference. We test whether the student’s level in the degree programme affects this difference. Results indicate that post‐tests may not demonstrate the full level of student mastery of learning objectives and that both the difficulty level of the questions asked and the level of students in their degree programme affect the difference between graded and ungraded assessments. Some of these differences may be due to causes other than grades on the assessments. Students may have benefited from the post‐test, as a review of the material, or from additional studying between the post‐test and the final examination. Results also indicate that pre‐tests can be useful in identifying appropriate changes in course materials over time.     

Team-based learning in anatomy: an efficient, effective, and economical strategy

Team-based learning (TBL) strategy is being adopted in medical education to implement interactive small group learning. We have modified classical TBL to fit our curricular needs and approach. Anatomy lectures were replaced with TBL that required preparation of assigned content specific discussion topics (in the text referred as discussion topics), an individual self-assessment quiz (IRAT), analysis of the discussion topics, and then the team retaking the same quiz (GRAT) for discussion and deeper learning. Embryology and clinical correlations were given as lectures. Unit examinations consisted of graded IRAT and GRAT. The National Board of Medical Examiners (NBME) Subject Examination was the comprehensive final examination. To evaluate the effect of TBL on student performance we compared the departmental and NBME subject examination scores between the traditional and TBL curricula. We collected five years of data on student performance in TBL-based anatomy and lecture-based preclinical courses. Our results show that departmental and NBME subject examination scores for TBL-based anatomy were higher than those for lecture-based anatomy. We subsequently compared average NBME scores for anatomy with those in other preclinical courses that were lecture-based. Average NBME anatomy scores were significantly higher than those for all the lecture-based preclinical courses. Since the introduction of TBL in anatomy, student performance has progressively improved in the NBME subject examination. Students perceived TBL as a motivator to be a responsible team member and to contribute to collective learning by the team. Further, it reinforced self-directed learning and fostered an appreciation for peer respect. Interestingly, these perceptions were uniform irrespective of student course performance.
