## Reflection: Developing a Conceptual Understanding The Law of Inertia - Section 2: Explore

Students had many questions after watching these videos.

The types of questions students ask is a useful informal assessment.  Their ability to ask questions is completely dependent of their conceptual understanding.

I was surprised that students accepted that an object on a table is being acted on by a normal force pushing up against gravity.  They did not have questions about this.

7/22 students needed vocabulary support for vertical and horizontal. This is the legacy of teaching them “hot dog” and “hamburger” in kindergarten.

4/22 students said they still didn’t completely understand how objects can stay in motion because all the objects they see stop.

1 student didn’t understand why the block moving on the frictionless surface had balanced forces once it was away from the piston.

All of these questions demonstrated that students were thinking critically about the content and grappling with their developing understanding of the law of inertia.
