The SASS is administered online during the last week of instruction, to be completed before the final exam.
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").

Of the 24 student learning outcomes in the SASS, 21 were self-reported as being achieved by at least 85% of students, listed below in order of decreasing success:
23. Describe plausible requirements for life. (100%)
20. Describe key features of terrestrial planets. (98%)
10. Explain how stars produce energy. (98%)
18. Describe characteristics of the universe a long time ago. (96%)
22. Explain why Pluto is not currently categorized as a planet. (96%)
1. Predict positions and cycles of stars, using a starwheel. (94%)
2. Explain sun cycles and seasons. (94%)
3. Explain and predict lunar phases and times. (92%)
24. Explain difficulties in investigating the possibility for extraterrestial life. (92%)
11. Explain the relationship between star brightness and distances. (90%)
12. Predict the size of a star based on brightness and temperature. (90%)
14. Explain evidence for the shape/size/composition of our Milky Way galaxy. (90%)
15. Explain evidence for how our Milky Way galaxy came to be. (90%)
17. Explain evidence for the expansion of the universe. (90%)
13. Explain different stages a star will go through, based on its mass. (88%)
19. Explain evidence for how our solar system came to be. (88%)
21. Describe key features of jovian planets. (88%)
5. Explain differences between models of planetary motion. (86%)
9. Explain which telescopes should be funded based on relevant criteria. (86%)
6. Explain evidence for the heliocentric model of planetary motion. (86%)
16. Explain how the speed of light affects observations of distant objects. (86%)
As discussed in a previous post, student learning outcomes 10, 11, 12, and 13 for Cuesta College students were directly assessed using the Star Properties Concept Inventory (SPCI, Janelle M. Bailey, "Development of a Concept Inventory to Assess Students' Understanding and Reasoning Difficulties about the Properties and Formation of Stars," Astronomy Education Review, Vol. 6, No. 2, pp. 133–139, August 2007), and scores were found to be comparable to results from 1,100 large research university students that have completed introductory astronomy and earth sciences courses.
However, three student learning outcomes were self-reported as being achieved by less than 85% of students, listed below in order of decreasing success:
4. Relate planets in the sky to a solar system map. (80%)
8. Describe different powers of optical telescopes. (80%)
7. Describe how optical telescopes work. (78%)
As per the ACCJC (Accrediting Commission for Community and Junior Colleges), results from this indirect assessment SASS tool, along with the direct assessment SPCI tool will be used for course/program improvement by increasing emphasis on these lowest three learning outcomes in instruction in future semesters.
