Reflection: Discourse and Questioning DC Electronics Exploration - Day 2 - Section 2: Defining Voltage and Current

 

While examining the results of the Ohm's Law activity in this lesson, I noticed that students struggled to identify the relationship between I and V as I had posed it. This despite the fact that I knew, from the previous class, that students had , indeed, uncovered Ohm's law from the data they collected.

In this video reflection I take a look at what I think was happening for my students. I think it's an interesting example of how a simple change in a question can unlock student responses.

DC Electronics Exploration - Day 2

Unit 3: Electricity and Energy Transfer
Lesson 4 of 13

Objective: Students will consolidate their learning about Ohm's law.

Big Idea: Ohm’s law relates current, voltage, and resistance in a very simple formula: V = IR.
