8. Representative Instructional Methods (Describe instructor-initiated teaching strategies that will assist students in meeting course objectives. Include examples of out-of-class assignments, required reading and writing assignments, and methods for teaching critical thinking skills.)

a. Out-of-class assignments: students will need to complete assigned problems and projects.
b. Reading assignments: Instructor will assign text readings for discussion of a topic in class.
c. Writing assignments:
1. Students will submit written homework assignments.
2. Students may be assigned papers including mathematical modeling.
d. Critical thinking:
1. Lecture/discussion to understand problem-solving process.
2. Students will practice critical thinking in small group problem solving.
3. Students will evaluate proposed solutions in light of constraints of the problem.
e. Resources available on CD and the Internet may be used to augment the text.

9. Representative Methods of Evaluation (Describe measurement of student progress toward course objectives. Courses with required writing component and/or problem-solving emphasis must reflect critical thinking component. If skills class, then applied skills.)

a. Written individual assignments and/or journal- to demonstrate individual student progress toward objectives.
b. Small group presentations- to demonstrate student participation in problem solving process.
c. Written exams/quizzes - to reflect student knowledge of vocabulary, concepts, and application of concepts to problem solving as presented in lectures and discussion, small group sessions, and text readings.
d. Final Examination - to reflect student knowledge of vocabulary, concepts, and applications of concepts to problem solving as presented in lectures and discussions, small group sessions, and text readings.
e. Participation - to reflect student involvement in class discussions, small group sessions and presentations, etc.
