Lab Reports
All lab reports are due one week after the lab, and must be
turned in at the beginning of the lab session. Partners may
discuss the lab with each other, but lab reports should be
done individually. Extensions may be granted under
extenuating circumstances (please contact the TA). The late
submission policy for lab reports is as follows:
For each day -15%.maximum 3 days
There should be a few sections common to all lab reports.
These are a brief introduction, theoretical background,
procedures and methods, results and a short conclusion.
For all figures, axes must be titled and labeled properly.
Processed data should be included in the results section
along with a short discussion on how they were obtained.
The quality of writing and manner of presentation is
important, and grading will reflect this. Write concisely
without round-about wordiness and repetitive repetition,
and repetition. Please be sure to answer all of the questions
in the lab handouts.

Teaching & Learning Methods
-
-
Active learning, where students should be active and involved in the learning process inside the classroom,
will be emphasized in the delivery of this course.
Different active learning methods/approaches such as: Engaged Learning, Project-Based Learning,
Cooperative Learning, Problem-based Learning, Structured Problem-solving, will be used.
The teaching method that will be used in this course will be composed of a series of mini lectures
interrupted with frequent discussions and brainstorming exercises. PowerPoint presentations will be
prepared for the course materials.
A typical lecture would start with a short review (~ 5 minutes) using both PowerPoint presentations and
the blackboard. This review will also depend on discussions which will gauge the students’ digestion of the
previous material. Then, the students would have a lecture on new materials using PowerPoint
presentations and blackboard. The lecture presentation will be paused every 15 – 20 minutes with
brainstorming questions and discussions that will allow the students to reflect and think in more depth
about what they learned in that presentation. Then, some example problems will be presented and
discussed with the students to illustrate the appropriate problem solving skills that the students should
learn. The lecture will be continued for another 15 – 20 minutes, followed by examples and/or a quiz
covering the materials taught in the previous two weeks.

Attendance
Class attendance is required and applied according to the university regulations (student’s
guide page 43). Data support the idea that class attendance improves learning. It is very
difficult as well as uninspiring for me to help a student who does not attend lectures. What
is created in the classroom cannot be reenacted.
Make-up tests will be done according to the university regulations. Please see student’s
guide pages 44-45.
Student Conduct
All University regulations apply to this course. In particular, the policies concerning
academic dishonesty and withdrawal from a course apply. May 6th is the last day to
withdraw. I will sign drop slips without restriction.
