Gathering Evidence

PART 1

Go To Gathering Evidence (Part 2)

Teachers can learn a great deal about their students' level of conceptual understanding and reasoning skills by monitoring small group and whole class discussion. The teacher who knows what to ask and when to listen can gather useful evidence about students' understanding, and can use that evidence to determine next steps in teaching. Consider the teacher's role in the whole class discussion described below, from a combined fifth and sixth grade classroom. The students are investigating the fractional relationships among cubes and rods of different size. Their explanations refer to the relationship among two cubes, where five of the small cubes fit along one side of the large cube.

Discussion Questions

  • Juan has the correct answer. What could you ask him to determine if he knows why 125 is correct?
  • What is David thinking? What might you have asked him if you had been the teacher?
  • David has made an error in counting the number of cubes on the surface. How would you help him correct this?
  • Based on this clip, do you agree that the teacher knows more about how well David understands the volume of a cube than about Juan?
