Universities are under increasing pressure to equip graduates with a broader set of competencies, such as communication, teamwork and leadership skills, that go beyond subject-specific knowledge. This, alongside growing student numbers in higher education, creates pedagogic challenges, especially with regards to assessment design. Conventional assessment modalities, such as individual essay writing, are costly to scale up and poorly suited for the development of further desired competencies. To address these challenges in the context of a first-year economics module, we replaced a 1,000-word individual written assignment with a group video assignment, where students were required to work in small teams to create a three-minute video on a contemporary economic issue. Focus groups and module evaluation questionnaires were used to elicit students' perceptions of how the group video assessment contributed to their learning experience and skill development, how it compares with other modes of assessment, as well as suggestions for improved implementation. Our analysis generates insights on all these aspects. Students reported a preference for diversity in assessment methods, and found the video assignment to be a positive, engaging but also challenging experience, which provided the opportunity for collaboration and development of diverse skills.
