Supervised study involves individual or small group instruction led by a teacher to help students learn course material and study skills. It can take various forms, such as a teacher staying after class to help students or employing special teachers to work with students. Organizing periods to split time between theoretical lessons and practical work or assigning students tasks to complete during library periods are other methods. Supervised study aims to address the needs of heterogeneous classrooms and help weaker students by bringing students closer to teachers and the learning process.
