Nervous System Test Objective: To check student understanding of all knowledge objectives listed in Student Matrix. Materials: Appropriate copies of student tests. Classroom sets are appropriate if students are using their own paper. Preparation: 1. Observe students carefully throughout the course of the unit to determine which test level is the most appropriate for the class. 2. Level A—Most difficult, geared toward GT and Honors classes 3. Level B—Moderate, geared toward most students 4. Level C—Easiest, geared toward lower performing classes or ESL 5. Students should receive their test review before being given the test. 6. Read each test version you will be using very carefully before handing out, making sure students have been taught all materials. 7. Scoring of the test with point values for each section is left to teacher discretion. Presentation: Hand students copies of the tests, employing classroom management techniques to avoid cheating.
