2 BRAZOSPORT COLLEGE SYLLABUS CHEM 1412 General Chemistry II II COURSE EVALUATION Student Evaluation One hour exams are designed to measure the student's mastery of the course objectives. Homework assignments and fifteen-minute pop tests are designed to indicate whether or not the student is doing the assigned reading carefully. Laboratory exams, if any, are intended to measure the student's laboratory techniques, understanding of experiments done, and how the student can apply concepts covered in lecture to practical situations. The laboratory grade will be the average of the experiment grades and exam grades. The course grade will be determined from the following: Quizzes 60% Lab 20% Final 20% TOTAL 100% Each instructor will announce the exact percentages to be used at the beginning of the course. Instructor Evaluation A. Students will be given an opportunity to evaluate their instructor and the course content. B. Instructor will review and evaluate in terms of withdrawal rate. C. Final grades given will be reviewed in an effort to determine if a pattern of high or low grades exists. Department Evaluation A.
