### Education research: formative SASS student learning outcomes assessment (Cuesta College, fall semester 2013, second midterm)

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) to Physics 205A students at Cuesta College, San Luis Obispo, CA. This is the first semester of a two-semester introductory physics course (college physics, algebra-based, mandatory adjunct laboratory).

Different sections of the SASS are administered online just before each of two midterms, and the final exam.

The SASS results from the second midterm of the semester are compiled below. Values for the mean and standard deviations are given next to the modal response category for each question. Listed are the percentages 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").
