What change could Ms. Fischer make to improve her teaching based on her students' test scores?

The option that suggests asking for check-for-understanding questions as she goes through the problems is a highly effective instructional strategy. This approach allows Ms. Fischer to actively engage students in the learning process and assess their comprehension in real-time. By asking these types of questions, she can identify areas where students are struggling and adjust her teaching accordingly.

This method encourages participation and gives students the opportunity to clarify concepts while they are still fresh in their minds. It fosters a more interactive classroom environment and helps ensure that students grasp the material before moving on to new content. Additionally, regular checks for understanding can build student confidence and encourage a growth mindset, as they see their areas for improvement and understand that questions are welcomed.

In contrast, merely increasing homework assignments or reducing the number of examples used might not address the root of the problem. Also, providing answers during instruction can lead to rote learning rather than genuine understanding, as students may miss the opportunity to work through the problem-solving process themselves.
