Assessment and Requirements
Assessment will be conducted as follows:
- Problem solving skills will be assessed in the classroom by the instructor as each student is guided in the assembly of information and strategies for its analysis and interpretation; and later as each submitted homework problem set is read.
- Cognitive skills will be assessed by the instructor as homework problem sets submitted by each student are read to see how the student has connect their method of solution with possible physical relationships suggested during lecture.
- Critical thinking skills will be assessed by the instructor during numerous problem sessions with the entire class, in which each student presents solutions to problems assigned in advance on the blackboard, while the instructor circulates about the classroom engaging students in discussion about various strategies involved in solving the problem under consideration. Later evaluation of related assigned homework problems, quizzes, and tests, allow the instructor to verify such assessment.
- Communication skills will be assessed by the instructor while interacting with students in the classroom, with follow-up questions during oral presentations on the blackboard, and with written comments made on submitted homework problem sets.
