Scoring Guide and Sample Student Work

Select a score point in the table below to view the sample student response.

Score	Description
4	The response demonstrates a thorough understanding of the basic principles of reflection and refraction of waves. The response clearly describes an example of light being reflected in the room, and correctly draws a labeled diagram of a reflected light ray. The response also clearly describes one example of refraction in the room and describes what happens when light is refracted.
4
3	The response demonstrates a general understanding of the basic principles of reflection and refraction of waves.
2	The response demonstrates a limited understanding of the basic principles of reflection and refraction of waves.
1	The response demonstrates a minimal understanding of the basic principles of reflection and refraction of waves.
0	The response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.
