Research Validation Summary
Based on Research Into:
- Student thinking
- Student interviews
- Expert review
- Appropriate statistical analysis
- At multiple institutions
- By multiple research groups
- Peer-reviewed publication
The multiple-choice questions on the LPCI were developed based on research into the dimensions and facets of students’ mental models of lunar phases. Questions and multiple-choice answers were written based on the concept domains outlined for the LPCI and reviewed by experts. An initial version of the LPCI was tested with over 400 introductory astronomy students and appropriate statistical analyses of reliability, difficulty, concentration and discrimination were conducted. The identified several items to be revised. The LPCI has been given to over 750 introductory astronomy students at several universities.
- R. Lindell, Measuring Conceptual Change in College Students' Understanding of Lunar Phases, presented at the Physics Education Research Conference 2004, Sacramento, California, 2004.
- R. Lindell and J. Olsen, Developing the Lunar Phases Concept Inventory, presented at the Physics Education Research Conference 2002, Boise, Idaho, 2002.
- R. Lindell and S. Sommer, Using the Lunar Phases Concept Inventory to Investigate College students' Pre-instructional Mental Models of Lunar Phases, presented at the Physics Education Research Conference 2003, Madison, WI, 2003.

Typical scores from Lindell 2004. These results are for a primarily non-science major introductory astronomy course at a large public American university. The normalized gain for this data is 0.54.
More typical results from Lindell and Sommer 2003 for introductory astronomy courses at eight institutions.
