I. Course Description A. Course Organization - Course overview and goals: The course considers selected topics in general, organic, and biochemistry as these areas relate to the health sciences. It is the intent of the course to impart to the student an understanding of the attitudes, methods, and theories by which chemistry attempts to explain basic chemical phenomena within the body.
- Methodology: The course is structured to include 45 hours of lecture/recitation and 30 hours of laboratory experience. Utilization is made of in-house prepared materials, films, models, and demonstrations. Each lecture is designed to generate questions about how the concepts relate to the individual students and to health sciences.

IV. Measurement and Evaluation - Measurement
Lecture: Four 1 hour written examinations each containing 30-40 multiple choice questions. Laboratory: 13 graded laboratory reports, some requiring quantitative measurements and manipulations. A written or practical mid-term and/or final examination may also be given. - Evaluation: The evaluation mechanism is determined by the instructor. Currently, the following mechanisms are used.
1. The four lecture exams represent 80% of the final grade, and the remaining 20% is assigned to the laboratory work. 2. The three highest lecture exams represent 75% of the final grade with the laboratory work accounting for the remaining 25%. In either case, the grade is assigned on a criterion basis. |
