Exploring the feasibility of using very short answer questions (VSAQs) in team-based learning (TBL)

Twelve tips for introducing very short answer questions (VSAQs) into your medical curriculum

Most undergraduate written examinations use multiple-choice questions, such as single best answer questions (SBAQs) to assess medical knowledge. In recent years, a strong evidence base has emerged for the use of very short answer questions (VSAQs). VSAQs have been shown to be an acceptable, reliable, discriminatory, and cost-effective assessment tool in both formative and summative undergraduate assessments. VSAQs address many of the concerns raised by educators using SBAQs including inauthentic clinical scenarios, cueing and test-taking behaviours by students, as well as the limited feedback SBAQs provide for both students and teachers. The widespread use of VSAQs in medical assessment has yet to be adopted, possibly due to lack of familiarity and experience with this assessment method. The following twelve tips have been constructed using our own practical experience of VSAQs alongside supporting evidence from the literature to help medical educators successfully plan, construct and implement VSAQs within medical curricula.

Very Short Answer Questions in Team-Based Learning: Limited Effect on Peer Elaboration and Memory

INTRODUCTION

In team-based learning (TBL), single best answer questions (SBAQs) are traditionally used because immediate computer-assisted feedback facilitates team discussions. Recent improvements in digital marking systems and criticisms of non-analytical strategies in SBAQs have prompted the consideration of very short answer questions (VSAQs) as an alternative to SBAQs. We aim to compare the effect of VSAQs and SBAQs on peer elaboration and knowledge retention in TBL.

MATERIALS AND METHODS

Twenty-four second-year students from the Lee Kong Chian School of Medicine participated in a mixed-methods study that included a randomised controlled crossover trial with two intervention arms (TBL-VSAQs and TBL-SBAQs). Two TBL sessions were conducted, with one topic covered each. Students were randomly allocated into six teams of four members. Individual and team scores and completion times were measured, and students were surveyed on their TBL experience. A follow-up quiz on the same topics was administered two weeks later to assess knowledge retention.

RESULTS

Individuals scored lower for VSAQs than SBAQs in the second TBL topic (7.17 ± 1.52 versus 8.25 ± 1.48; p = 0.046), while findings in other metrics were non-significant. Follow-up quiz scores showed no significant difference in knowledge retention, although effect size and power were low. Students perceived VSAQs as more authentic and challenging, though most preferred the continued use of SBAQs for TBL.

DISCUSSION

VSAQs have a limited impact on peer elaboration and knowledge retention versus SBAQs in TBL.

CONCLUSIONS

We should be circumspect about implementing VSAQs in TBL especially for medical students at the pre-clinical level.
