Evaluation of a Chemistry Concept Inventory for general chemistry students at Finnish university

Abstract

A chemistry concept inventory (Chemical Concept Inventory 3.0/CCI 3.0), previously developed for use in Norwegian universities, was tested and evaluated for use in a Finnish university setting. The test, designed to evaluate student knowledge and learning of chemistry concepts, was administered as both pre- and posttest in first year general chemistry courses at the University of Jyväskylä. The results were evaluated using different statistical tests, focusing both on individual item analysis and the entire test. Some individual questions were found to be not discriminating or reliable enough or too difficult, yet the results, as a whole, indicate that the concept inventory is a reliable and discriminating tool that can be used in the Finnish university context.
