Enhancing learning outcomes through post-discussion homework: the role of collaboration and task type

This study investigates how post-discussion homework can be designed to sustain the inclusive, collaborative dynamics of seminar teaching. Through a 2 × 2 quasi-experimental design with 36 graduate students, we examined how social architecture (collaborative vs. individual homework) and task type (concept-oriented vs. case-oriented assignments) jointly relate to learning outcomes. Learning was assessed through rubric-based assignment performance, students' perceived learning ratings, and brief written open-ended interviews about collaborative homework. Across assignments, collaborative homework was associated with higher performance than individual homework, and this collaborative advantage was especially pronounced for the concept-oriented task, which required students to reorganize and articulate theoretical ideas, compared with case-oriented assignments that emphasized applying established concepts to specific organizational cases. These findings suggest that while a collaborative social architecture is broadly beneficial, its potential for fostering deep learning and inclusive engagement appears to be strongest when it is paired with conceptually demanding work. The study offers an evidence-based framework for designing post-discussion homework as an integral phase of a continuous, collaborative learning cycle rather than as an isolated individual task.
