Facilitation guidance from the lesson plan — what to notice in student thinking and how to respond while teaching.
What to look / listen for
This is an opportunity for you to assess students’ ability to form hypotheses. They will develop two alternate hypotheses. Their hypotheses should be similar to the following:
- If the current from the computer is repeatedly switching from on to off (at a certain frequency), then when we hook the LED up to it, the LED will blink on and off and back again at a certain frequency but will remain the same color with each blink.
- If the current from the computer is repeatedly flipping something in the system, then when we hook the LED up to it the LED will blink from green to red and back again at a certain frequency.
What to do
One way to quickly assess students in this practice is to use a class checklist. This checklist would be for the teacher only--not for public display. More information about what this checklist would look like is provided in the assessment guidance within the lesson.
