Evaluation Guidelines:

Summative evaluation of students in Physics 2204 shall utilize a variety of evaluation instruments. Primarily, these are designed to test students’ basic knowledge of content, their understanding and ability to apply content, and ability to synthesize and problem solve (higher thinking skills) with respect to the content.

Summative evaluation of students in science courses must involve a variety of evaluation instruments. Midyear examinations, final examinations, and unit tests/quizzes, completed by students are traditional instruments which must be a part of any summative student evaluation scheme. As well, Performance Assessment instruments shall be used for a portion of the summative evaluation.

Unit Tests/Quizzes:

All unit tests are based on the learning outcomes of the course and the objectives. The tests include a variety of testing techniques such as multiple choice and essay items. There is at least one test after each unit and sometimes the unit can be broken into several sections for the purpose of testing if he teacher deems it necessary. Each test is designed for completion in a single class period.

Performance Assessment:

Performance assessment instruments shall be used for a portion of the summative evaluation. Examples of performance assessment instruments are assignments, written homework, science fair, class observations, science projects, laboratory reports, in-class presentation, in-class cooperative education, practical laboratory tests, observation checklist, computer assisted evaluation and teacher-student interviews, research reports, field trip reports, portfolios, etc.

Teachers can determine the performance assessment instruments used in Physics 2204. However, a variety of instruments shall be used to accurately assess students’ understanding of learning outcomes, with a focus on core labs and STSE topics.

Cumulative Midyear Examination:

The mid-year examination tests all course objectives to that point. It will include multiple choice, essay items and short answer questions on elective units. The test is designed to be completed in a 2 hour time period.

Final Examination:

The final examination is based on the course objectives for the entire year. It uses the same testing techniques used in the mid-year examination. The test is designed to be completed in a 2 hour time period.

Weighting of Evaluation Component:

Tests/Quizzes	25%
Performance Assessment	20%
Comprehensive Midyear Exam	20%
Final Examination	35%

Notes:

To parallel the evaluation for Chemistry 3202, performance assessments in Chemistry 2202 should primarily focus on STSE and core lab outcomes.
Student grades for the November reporting period comprised of results obtained from tests/quizzes (80%) and Performance Assessment (20%).

Table of Specifications:

A Table of Specifications is used for two main reasons. First, it guides the construction of examinations by outlining a percent value for each cognitive level and unit of study. Secondly, the total percentage for each unit directly corresponds to the suggested time for teaching that unit.

Unit	Cognitive Level %
Unit	Level 1	Level 2	Level 3	Level 4
Kinematics	5	13	5	23
Dynamics	5	17	5	27
Work and Energy	5	13	5	23
Waves	5	17	5	27
Total %	20	60	20	100

The evaluation instrument will contain 15-20% of core lab and STSE (Science, Technology, Society, and the environment) content.
