Los Angeles Valley College Student Learning Outcomes Assessment Report Courses and Programs Discipline: Astronomy Program/Course: Astronomy 1 and 5 SLO Representative: Dr. Joan Hackeling I. Student Learning Outcome Assessed II. Description of Assessment Method a. Describe the assessment tool (e.g., student essay, performance, etc.) b. Describe how the data was analyzed (rubric elements, etc.). Attach rubric if applicable. *** Please keep all data for at least 3 years. Department: Earth Science Semester/Year: Spring 2013 Department Chair: Jacquelyn Hams For Astronomy 1: a. Demonstrate an understanding that astronomy is based on observation of the sky and how those observations explain some basic phenomena of nature. b. Explain how light is used by astronomers to learn about the universe. For Astronomy 5: a. Demonstrate how a telescope is used to interpret celestial objects. b. Demonstrate how astrophotography is used to record and interpret features of a celestial object. a. A multiple-choice test was developed for the Astronomy 1 and 5 classes. For Astronomy 1, questions dealt with how light is analyzed to learn about the universe, planetary motion and relative sizes of major astronomical systems. For Astronomy 5 (laboratory), questions dealt with functional parts of a telescope, sky chart interpretation, and astrophotography. Scantrons were used to record test responses from students. An item analysis of responses for each question were examined to gauge whether or not students were grasping the concepts; 70% was considered an “acceptable” pass rate. b. All students present in the classes at the end of the semester (May 2013) were given the tests. 131 Astronomy 1 students were surveyed, and 53 Astronomy 5 students were surveyed. Both Astronomy instructors (Falk and Jandorf) participated in the process, and Dr. Joan Hackeling and Vivian Mun were consulted. Both Astronomy instructors jointly developed the test and examined the survey results and agreed upon the interpretation of results. III. Description of Sampling Methodology a. 4 sections of Astronomy 1 were offered (all during the day), 2 sections a.

All of these were assessed. b. Faculty - How many faculty (part-time and d. All students in both Astronomy 1 and 5 were assessed. full-time) taught this course? How many faculty participated in the SLO assessment process? c. Students - How many students in total were enrolled? How many students were assessed? d. Sampling (If this course offered more than one section, at least 1/3 of the total # of students must be assessed) - How was the sampling process conducted? (e.g., chose every 3rd student from roster) IV. Collaborative Review Both instructors collaborated on making the assessment test and interpreting the results. V. Assessment Results Astronomy 1: 74% of students answered correctly questions dealing with motions of the night sky. Only 43% of students correctly remembered details on planets, but this could be because one of the questions (dealing with planetary rings) was very detailed. Results from questions dealing with understanding stellar characteristics ranged widely (91-18% answered a. Describe the norming process and how interrater reliability was achieved (if applicable). a. Describe the relevant findings according to the criteria set by the assessment tool. (e.g., report results according to rubric evaluation criteria) the question correctly), despite a great deal of class time spent on this topic. The faculty is discussing using different activities to more actively engage the students on this topic. Students are grasping the range of sizes of objects in the universe, scoring between 73% and 100% correctly on questions dealing with this topic, so they are apparently understanding the relative sizes of objects. Astronomy 5 (laboratory): Most students understood interpreting a sky atlas (correct answers ranged from 100% to 66%). Students are doing better with Moon motions and eclipses (100%-80% correct. Failure rates for questions dealing with astrophotography were high (80%-50% correct), but could be attributed to the brief amount of time spent on this topic. Students were apparently somewhat confused about telescope parts (80%-66% correct responses), but this could be because the illustration on the test was referring to a telescope of a different design than those used in the laboratory sessions. VI. How Results were Used for a. Results will be used to select a new textbook for courses (“Astronomy Course/Program Improvement Today” by Chaisson) and exercises will be assigned to students from a. Describe how the results are going to be used “Lecture-Tutorials for Introductory Astronomy” by Prather and Slater. for the improvement of teaching, learning, or b.

Comparison to last SLOAC Cycle The results of these surveys will be used to adjust the amount of time Results (if this is the first time the course spent on topics that gave students the most difficulty, and to search for was assessed, leave this section blank) more effective student activities that would engage the students more and enable greater understanding of the concepts. a. Please state the improvement plan that was included in the report from the previous SLOAC cycle. b. What changes were implemented from the previous SLOAC cycle’s improvement plan? What changes, if any, were made that were not included in the improvement plan? What changes, if any, were made to the assessment process? c. How are the results from this SLOAC cycle similar to or different from the results from the previous cycle? a. More time was spent in the lecture courses on stellar characteristics and evolution, with more “hands-on” exercises. More emphasis was spent during the lab courses on Moon phases. The textbook used in the Astronomy 1 lecture class was changed in response to student complaints regarding the book formerly used. b. Students are doing better with Moon motions and relative sizes of celestial objects than in the previous cycle, but are still struggling with stellar characteristics and evolution.
