A math teacher plans her instructional delivery around resolving students' difficulties distinguishing between mode and median. What concept does this plan demonstrate the teacher's understanding of?

The teacher's plan to focus on distinguishing between mode and median showcases a deep understanding of fostering mathematical discourse among students. By addressing specific difficulties students face, the teacher is likely to employ targeted questioning strategies that encourage students to articulate their thought processes, engage in discussions about their reasoning, and explore the differences between the two measures of central tendency. This approach not only aids in clarifying concepts but also develops critical thinking skills, allowing students to raise questions, share ideas, and correct misconceptions collaboratively.

This method emphasizes an interactive classroom environment, which is essential for student learning in mathematics, as it promotes active participation and collective problem-solving, contributing to a deeper understanding of mathematical concepts.
