Force Concept Inventory (FCI)

Purpose

The FCI assesses students understanding of basic concepts in Newtonian physics including one-dimensional kinematics, Newton’s laws, two-dimensional motion with constant acceleration, and vector sums.

Population

The FCI is commonly administered in introductory college mechanics courses (algebra-based and calculus-based) and high school physics courses.

Typical Performance

In our models, we have found that the FCI and the FMCE have very similar scores. The plot below contains pretest and posttest scores on the FCI and FMCE from 259 introductory physics courses that are either reported in the literature or collected with LASSO. The average effect size (Cohen’s d) is approximately 1.

Validity

The FCI is one of the original concept inventories and the most widely used. Since its development validation standards have improved and several limitations in the FCI exist around the fairness of the questions for men and women (Dietz et al., 2012; Traxler et al., 2018).
