Validity and reliability of the force and motion conceptual evaluation

Abstract

The assessment of learning has become a key component in program evaluation, grant proposals, and education research. Assessment requires valid and reliable instruments. The Force and Motion Conceptual Evaluation (FMCE) is one of several multiple-choice tests used to evaluate the learning of force and motion concepts. Although many physics education researchers accept its validity and reliability, validity and reliability estimates based on typical statistical analyses of data have not been established. This study used FMCE post-test results for approximately 150 students in a first-semester college physics course to estimate reliability and content validity. The results indicate that the FMCE is a valuable instrument for measuring student learning.
