VIII. Methods of Evaluation and Assignments: A. Methods of evaluation for degree-applicable courses: Essays [X] Problem-Solving Assignments (Examples: Math-like problems, diagnosis & repair) [X] Physical Skills Demonstrations (Examples: Performing arts, equipment ) [ ]

For any course, if "Essays" above is not checked, explain why.

B. Typical graded assignments (methods of evaluation): 1. Homework exercises involving demonstration of computational skills and demonstration of analytical problem solving skills. (Homework exercises typically involve several course objectives mentioned. For instance, the homework problem asking the student to sketch the graph of involves analyzing a function, solving a trigonometric equation, sketching the graph, and possibly simplifying a trigonometric expression - 4 objectives.) Graded credit/no credit based on completion 2. Writing exercises that probe the students’ understanding of lecture concepts and homework problems. These exercises typically involve the calculation and proof of numerical or algebraic statements and compare the result of the task to establish or reject a conjecture. If the student rejects the conjecture, he/she must state why and sometimes rephrase the conjecture to make it true. Graded on accuracy. 3. Individualized and customized special assignments that enlarge upon the homework assignments. In these assignments, all students are assigned the same problem with different numerical coefficients. These will usually involve several objectives. Example: Find the minimum distance from a point to a given line, analytically, graphically, and numerically. The student has to perform several of the course objectives to work this problem: Solve a , formulate a mathematical model that generates the distance from the point to the line, sketch the graph of the quadratic function, and generate a numerical table of values listing the volume. Graded on completion and accuracy of the assignment. 4. Midterm exams. Each midterm exam typically emphasizes several objectives. Exams that are devoted primarily to algebra test each student’s ability to analyze functions, solve equations, sketch graphs and simplify expressions. Other exams test the student’s ability to analyze and graph conic section or resolve triangles by using identities, as well as solve equations and simplify expressions. Graded on accuracy. 5. Final Exam. The final examination will test the students on all objectives. Graded on accuracy. C. Typical outside of classroom assignments: 1. Reading a. Critical reading and thinking in application homework problems. For example: "A rectangular package can have a maximum combined length and girth (perimeter of a cross section) of 108 inches. Find the dimensions of the package of maximum volume." 2. Writing a. Three or four sentence responses, for example: Use your own words to explain how to determine if two functions are inverses of each other. 3. Other a. Analytical problem computation or sketch sample, for example: "Determine the amplitude, period, and phase shift for the given function. Graph the function over an of two complete periods."
