ABSTRACT The use of statistical indexes for a standard concept inventory test is a standard tools for evaluation of the test reliability and discrimination power, whereas the Rasch analysis is a well-known calibration technique for these tests. Herein we harmonize both tools in a step-by-step procedure for a better assessment of the student’s conceptual knowledge in physics. Initially we conducted a standard Force Concept Inventory test in a sample of students and evaluated the reliability and discrimination indexes of the items. Next we requested that all items’ indexes measurement in a given test must fulfill reliability and discrimination prerequisites, before using them for further calculation. After adding data from the supplementary FCI test we realized the fulfillment of this ad-hoc criterion, and next those data are used for a better assessment of the CI in physics knowledge and evaluation of major factors that affect students’ knowledge. |
