Research Validation Summary

Based on Research Into:

  • Student thinking

Studied Using:

  • Student interviews
  • Expert review
  • Appropriate statistical analysis

Research Conducted:

  • At multiple institutions
  • By multiple research groups
  • Peer-reviewed publication

The multiple-choice and true/false questions on the AMS were developed from a list of 25 astronomy misconceptions which were based on previous research on misconceptions as well as the authors experience teaching introductory astronomy courses. This list of misconceptions was given to students as a true or false survey. The true/false questions were then converted to multiple-choice questions were the answer choices included the commonly help misconceptions. This multiple-choice version was given to over 400 students at one institution.

Typical Results

True-false version: The 217 students in sections not receiving any special treatment of the misconceptions during instruction increased their average score from 48% to 63% +/- 4% (std. error), g = 0.29 +/- 0.07. The 71 students who were given classroom-response questions increased their average to 68% +/- 4.2% (std. error), g = 0.36 +/- 0.09. 

Multiple-choice version: For the 285 students in sections with no special treatment of misconceptions, scores increased from 30% to 45% +/- 3% (std. error), g = 0.22 +/- 0.035. The 36 students who were told that all the answers were false averaged 52% on the multiple-choice posttest +/- 3.9% (std. error), g = 0.33 +/- 0.05, whereas the 72 students who were given classroom-response questions increased their average to 64% +/- 3.9% (std. error), g = 0.46 +/- 0.038.

The latest version of the AMS, released in 2011, is version 1. There is a true/false version or a multiple-choice version of this test. The true/false version is most useful for educating instructors on common misconceptions their students may have. The multiple-choice version can be given to students to assess their understanding of these common astronomy misconceptions, and assess the effectiveness of your instruction at improving students' understanding of these topics.
