What should a teacher do after noticing that students did not master a concept after differentiated lessons?

Providing additional small group instruction on the concept is an effective approach for helping students who did not master the material after differentiated lessons. This method allows the teacher to focus specifically on the needs of those students, creating a more targeted learning experience. In a small group setting, the teacher can adjust the pace and teaching strategies based on the students' understanding, provide multiple explanations or demonstrations, and encourage more interaction and questions. This personalized approach can help clarify misunderstandings and give students the support they need to grasp the concept effectively.

In contrast, while designing extra homework or allowing a retake of the assessment can be beneficial, these strategies may not address the root of the misunderstanding or provide the instructional support necessary for mastery. Peer reteaching could also be a valuable method, but it might not ensure that the struggling students receive the tailored instruction that they need from a qualified teacher who can assess their misconceptions directly. Small group instruction positions the teacher to be actively involved in the learning process, fostering a better chance for students to achieve understanding.
