The classroom’s main activity is lecture interspersed with discussion. Problems are assigned to be completed and checked by the students. Examinations are given to evaluate the student’s level of understanding the material. In addition, each student is required to participate in a weekly laboratory exercise related to the lecture topic being covered, and is graded according to a written report, experimental technique, quality of results, and participation. Students will also be performing several presentations.
The main emphasis of the course is to learn to analyze problems and to be able to apply the proper equations and mathematical procedures to obtain a suitable solution. Students will be assessed with (3) three major exams, a final, lab reports, industry projects, quizzes and other homework.Grading Criteria:
Industry Projects--testing & designing projects includes budget report, letters, memos, etc.
Citizenship--quizzes, homework, etc
Final--exam covering all material from the semester
