The course will be presented using lectures, problem sessions, and class discussion. Videos, other audio-visual aids, as well as on-line material will be used where appropriate. The laboratory will be used to illustrate the practical aspects of the course material.
Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:
Lecture Material (70%)
- Two or more in-class tests will be given during the semester (20-30%)
- Any, all, or none of the following evaluations, at the discretion of the Instructor: individual/group assignments, in-class/on-line assignments/quizzes, in-class presentations, class participation [5% maximum] (0-20%)
- A final exam covering the entire semester's work will be given during the final examination period (30-40%)
- Pre-lab work (typically evaluated with a notebook inspection and/or pre-lab quiz), written experiment reports (either formal reports or report sheets), qualitative/quantitative results of experiments performed on unknown samples
- Written quizzes in addition to the pre-lab work may be given, at the discretion of the instructor
- Final Lab Exam(s) (written and/or practical, at the discretion of the instructor)
A student who misses three or more laboratory experiments will earn a maximum P grade.
A student who achieves less than 50% in either the lecture or laboratory portion of the course will earn a maximum P grade.
