### Education research: SASS, ECCE and student learning outcomes assessment (Cuesta College, spring semester 2014)

Student achievement of course learning outcomes are assessed by administering an Student Assessment of Skills Survey (SASS), a five-point Likert scale questionnaire (Patrick M. Len, in development), and a shortened version (22 out of 45 questions) of the Electric Circuit Concept Evaluation (David Sokoloff, University of Oregon) to Physics 205B students at Cuesta College, San Luis Obispo, CA. This is the second semester of a two-semester introductory physics course (college physics, algebra-based, mandatory adjunct laboratory).

The SASS is administered online during the last week of instruction, to be completed before the final exam. The ECCE is administered in class during the last week of instruction.

The SASS results from this semester are compiled below. Values for the mean and standard deviations are given next to the modal response category for each question. Also listed is the percentage of students who have self-assessed themselves as having successfully achieving a learning outcome (responding "average," "above average," or "excellent") as opposed to not achieving success with a learning outcome (responding "very poor" or "below average").

Student learning outcomes 16, 17, 18, and 19 for this semester were also directly assessed using a shortened version of Electric Circuit Concept Evaluation.

As per the ACCJC (Accrediting Commission for Community and Junior Colleges), results from this indirect assessment SASS tool, along with the direct assessment ECCE tool will be used for course/program improvement by increasing emphasis on these lowest three learning outcomes in instruction in future semesters.
