Learning Activities

The course will be presented using lecture, problem sessions and class discussions.  In-class demonstrations of computer-based educational materials and videos will be used where appropriate.  The laboratory consists of experiments performed by students, either individually or in pairs, which illustrate the lecture material, or encourage good experimental technique. Close coordination will be maintained between laboratory and classroom work whenever possible.  This will be accomplished by discussing laboratory experiments in class and, when necessary, by using the lab period for problem solving.

Means of Assessment

Lecture Material (75%)

  • Two or three in-class tests will be given during the semester (30% in total).
  • A final exam covering the entire semester’s work will be given during the final examination period (30%).
  • Any or all of the following evaluations, at the discretion of the instructor:  problem assignments, quizzes, class participation (5% maximum). (15% in total)

Laboratory (25%)

  • Written reports for each experiment will be handed in and graded.  These reports will either be complete reports, to be handed in in the laboratory notebook, or short reports, to be handed in on report sheets.  There will also be several written quizzes based on the procedure and theory of the various experiments. (16 - 18%).
  • Quantitative results of experiments performed on unknown samples will be graded (0 - 2%).
  • A practical laboratory exam will be given in the last lab period of the semester (5%).
