유치원 , 초등 , 중등학교 과학 교재의 ' 물질의 성질 ' 관련 학습 내용 전개에 대한 특징 분석 = Reserch Article : An Analysis of the Characteristics of Learning Contents Structure related to ' Properties of Matter ' of K - 12 Science Textbooks

다국어 초록 (Multilingual Abstract)

The purpose of this study was to find out the characteristics of learning contents structure of K-12 science textbooks. The characteristics are related to 7 main concepts of matter properties; reaction rate, other reaction, density, solution, state change, absorption, and surface property. The contects are analyzed into 5 types of characteristics; type of concept extension, type of concept deepness, type of same level concept, type of confusion with other concepts, and type of concept interruption. First two types are positive content structures, but the others are negative structures. The findings are as follows. First, a lot of learning contents have the characteristic of `type of same level concept`. There are few which have the characteristic of `type of concept deepness`. Second, there are a lot of concepts related to `properties of matter` which are not represented any more in middle and high school science textbooks. Those concepts are importantly taught in early childhood education and elementary school science. Most of the learning contents don`t represent `type of concept deepness`. Therefore the science textbooks needs to be restructuring.
