Nervous System Test

Objective: To check student understanding of all knowledge objectives listed inStudent Matrix.

Materials: Appropriate copies of student tests. Classroom sets are appropriate ifstudents are using their own paper.

Preparation:1. bserve students carefull! throughout the course of the unit to

determine which test level is the most appropriate for the class.2. "evel A#Most difficult$ geared toward %T and &onors classes3. "evel '#Moderate$ geared toward most students

4. "evel C#(asiest$ geared toward lower performing classes or (S"5. Students should receive their test review before being given the test.6. )ead each test version !ou will be using ver! carefull! before handing out$

making sure students have been taught all materials.. Scoring of the test with point values for each section is left to teacher

discretion.

Presentation:&and students copies of the tests$ emplo!ing classroom managementtechni*ues to avoid cheating.
