When a teacher decides to re-teach certain concepts after disappointing exam results, what should she do?

The choice to group students with similar needs is a strategic and effective approach to re-teaching concepts after disappointing exam results. This method allows the teacher to tailor instruction to address specific gaps in understanding that different groups of students may have. By grouping students based on their needs, the teacher can provide targeted support and differentiate instruction, thereby enhancing the learning experience.

For instance, if some students struggled with a particular concept while others grasped it, the teacher can focus on re-teaching the difficult material to those who need it most, creating a more conducive learning environment. This approach recognizes that students learn at different paces and may require varied instructional strategies, thereby promoting better comprehension and ultimately improving their performance in future assessments.

In contrast, re-teaching the same way as before might not address the root causes of misunderstanding, while evaluating the exam for unclear questions is beneficial but does not directly impact students' learning without fostering new instruction. Choosing to only re-teach those who failed overlooks the opportunity to help all students consolidate their learning, as even students who passed could benefit from additional reinforcement.
