The ALLS is administered as a pre-test on the first laboratory meeting, before any introduction/instruction took place; and as a post-test on the last laboratory meeting.
The results from the pre- and post-test questions follow below. Values for the mean and standard deviations are given next to the modal response category for each question, along with a Student t-test for the probability of null hypothesis rejection, and the class-wise Hake gain. (Matched-pair Hake gains were not calculated for each student, as pre-instruction values such as "5" would result in undefined values.) For statistical purposes, blank entries were treated as "3. Neutral," and multiply-circled entries such as "12," "23," "34," and "45" were treated as "1," "2," "4," and "5" respectively.

No statistically significant (p > 0.05) shifts were observed for relating astronomy to personal experience (question 2), interest in astronomy-related news (question 5), pondering astronomy-related questions (question 6), self-efficacy in use of calculators and math in astronomy (questions 7 and 8), individual/group learning habits (questions 9, 10, 11, and 12), and self-efficacy in math/science (questions 13 and 14).
Of note is a statistically significant (p < 0.05) downward shift in interest in using telescopes/binoculars in astronomy (question 1)!
However, there are statistically significant (p < 0.05) gains in being able to find astronomy-related news/information (question 3), finding night sky objects (question 4), and rating the expected/experience difficulty of this course (question 15). The first two of these positive self-reported shifts correlate well with two of the student learning outcomes for this course:
- Keep abreast of present-day discoveries and developments in astronomy (current events).
- Construct and use devices to measure locations and sizes on the celestial sphere (observational astronomy).
(For completeness, the remaining four student learning outcomes are listed below, and are measured primarily through grade-related assessment):
- Apply laws of spectroscopy and gravitation to remotely determine properties of satellites, planets, and stars (astronometry).
- Develop and test physical models of the properties of solar system bodies (planetology).
- Collect data, evaluate the data using error analysis, draw conclusions from the data.
- Explain the information in a laboratory report.
