The Level of Mastery of Selected Classificatory Science Concepts.

The purpose of this study was to assess the potential use of A Schema for Testing the Level of Concept Mastery in measuring attainment of classificatory concepts in science. Classificatory concepts from the biological, earth, and physical sciences were included. For each of the 30 concepts included in the study a 12-item test was constructed to measure children's attainment of each of twelve schema tasks. The schema is useful in identifying and analyzing classificatory concepts and preparing related concept attainment tests. The tests have been administered to sixth-grade children to determine the level of concept attainment by concept and among science areas.
