Micro-teaching is an effective strategy for teaching and improving specific skills, such as explaining concepts to students. In this method, a teacher practices teaching a small group (often just a few students) with a focus on a specific skill, such as explaining, questioning, or presenting information.
It allows the teacher to receive feedback and make adjustments in a controlled, low-risk environment. The key feature of micro-teaching is that it is focused on improving teaching skills through practice and reflection.
