Analysis of Hierarchy for High School Students' Concepts about Genetics Through the Knowledge State Analysis Method

Abstract

The purpose of this study was to analyze hierarchy for high school students' concepts about genetics. The assessment of genetics related concept was conducted for 10th and 11th grade students and a hierarchy map was schematized based on the evaluation result using Knowledge State Analysis Method. Some differences were found when comparing the result of whole students' hierarchy with hierarchy on 7th national science education curriculum. In analyzing hierarchy by grade, concepts of highest and lowest level turned out same but some concepts of middle level changed. In case of analysis of hierarchy for concepts about genetics by score, as score was higher, the number of concept in lower level became larger and the relationship among concepts became more structurized. Following studies are required to develop specific teaching strategies for having effective genetics concept and conduct case study of applying the concept hierarchy through this method to class in the field.
