Medical students' perception and academic performance after team-based and seminar-based learning in human anatomy.

Objectives: Student-centered educational strategies like problem-based learning (PBL), case-based learning (CBL), team-based learning (TBL), and seminars enhance group and self-learning. This study was carried out to evaluate students' achievements in anatomy topics delivered through TBL sessions and seminars and to survey student preferences regarding these two modalities in anatomy learning.

Methods: TBL was conducted through individual readiness assurance tests (IRATs), group readiness assurance tests (GRATs), mini-lectures, and application exercises.
