Assignments students completed: All of the above mentioned students learning outcomes were examined. Questions and problems were given to students to apply physics knowledge and skills related to specific learning outcomes. The assessment tools consist of instructor assigned lecture tasks, lab tasks with department lab rubric. The tasks are lecture quizzes, lecture tests, lab performance and lab reports. a. Describe and analyze physical situations using graphical representations. This learning outcome was assessed 10 times during the semester. In addition to mid term and end of semester final exam, 8 different tasks were used to assess this learning outcome. Velocity versus time and distance versus time graphs assess students’ ability to create and interpret graphs when given the motion characteristics and to deduce information such as velocity, displacement, and acceleration of a moving object. b. Use vectors, calculus, algebra, geometry and trigonometry to describe physical situations and to solve physical problems in one and two dimensions. c. Compute physical quantities using scientific notation, significant figures as well as basic SI units and convert from one set of units to another. d. Analyze physical properties of motion including position, displacement, velocity, linear acceleration and time; use them to solve motion problems. e. Draw force diagrams, apply Newton's laws of motion and use them to solve force and motion problems. Just like the first learning outcome, 10 tasks including mid term and final examination were used to assess learning outcomes b to e. Assessment tasks used were quizzes, homework, class presentations and exams. f. Utilize energy, work, power and their relationship to solve problems; apply conservation of energy principle to solve problems. In addition to midterm and final exams, five other tasks that included quizzes, homework, presentations were used to assess this outcome. g. Utilize momentum, impulse and their relationship to solve problems; apply conservation of momentum principle to solve collision problems in one and two dimensions. Midterm and final exams and four other tasks throughout the semester were used to assess this outcome. h. Analyze physical properties of rotational motion including centripetal acceleration, torque, angular momentum, rotational energy; and use them to solve rotation problems. Midterm and final exams and two other tasks throughout the semester were used to assess this outcome. i. Utilize Newton's law of gravity to analyze and solve problems associated with Kepler's laws of planetary motion Six different tasks were used to assess this learning outcome. j. Perform experiments as described in the rubrics and draw meaningful conclusions from data and present them as part of a clear, well-organized lab report. Laboratory experiments were assessed separately. Throughout the semester students performed 14 experiments. For each experiment they are required to produce a report. These reports and their performance in the lab are used to assess their ability to perform experiments and draw conclusions based on the results. Specifically following guidelines were used to assess this outcome: Quality of the scientific content Content of the introduction Description of the experimental procedure Theoretical background Analysis of the data and results Error calculations Interpretation of the results and of their uncertainty; relation to the wider context Understanding of the limitations of the experiment; extent to which the conclusions accurately reflect the data and their limitations Written style and clarity Organization and logical flow Quality of the presentation (general presentation and, where applicable, presentation of the figures, tables, symbols and equations, and references) Lab performance was assessed on observations by the instructor and based on evidence of good laboratory practice 3. Evidence and instruments used Grades were given to students based on how they perform on each problem. The assignments are distributed throughout a semester and the gen ed objectives for each assignment are recorded on the department assessment grid in Excel which was designed with reference to ABET requirement. Student learning evidence as scores is used in the assessment model. The gen ed assessment data have been computed according to the percentage of students scoring Excellent, Good, Met Standard, and Unsatisfactory. Please see the attached Excel sheet for example. 4. Analysis and results A weight of 3 for E, 2 for G, 1 for M, 0 for U have been used. The data from spring 2013 is consistent with original findings we submitted earlier in March. 5.
