고등학교 생물Ⅱ 교과서 5종의 세포호흡 관련 내용에 나타난 개념들의 정교화 = The Elaboration on Concepts Related to Cellular Respiration in Five High School BiologyⅡ Textbooks

다국어 초록 (Multilingual Abstract)

The content related to cellular respiration in current five school biologyⅡ textbooks was analyzed to describe what concepts are represented and how these concepts are elaborated.The uppermost principle concepts related to cellular respiration were identified as requirements, processes, and products. Concept mapping revealed that the presentation and organizational strategies as well as the number of concept presented had little difference among textbooks, except that respiration rate, and putrefaction was not included in textbook C, and A, respectively. All textbooks analyzed in this study elaborated on many of their concepts related to cellular respiration, but to different degrees. Among textbooks, textbook E presented the most amount of elaboration, whereas the least amount of elaboration was included in textbook D. The variation in the quantity of elaboration of each concept in a textbook was very wide.Elaborate analogy was not used for many concepts related to cellular respiration in the textbooks. A few of defects in elaboration on the concepts related to cellular respiration in each textbook was found, which should be corrected in the following edition.

국문 초록 (Abstract)

≫고등학교 생물Ⅱ 교과서 5종의 세포호흡 관련 내용을 범주별로 추론한 결과 최상위 주요 개념은 세포호흡 필요조건, 세포호흡 과정, 세포호흡 산물 등의 세 가지로 확인되었으며, 개념도 작성을 통해 분석한 결과 제시된 개념들의 수는 교과서별로 약간의 차이가 있었으나 개념들의 조직이나 위계에는 별 다른 차이가 없었다. 분석대상 교과서 5종 모두 다수의 세포호흡 관련 개념들에 대해 전반적인 정교화가 이루어져 있었으나 정교화의 정도에는 개념에 따라 상당한 차이가 있었다. 세포호흡 관련 세 가지 최상위 주요개념들 중 세포호흡과정에 대한 정교화 정도가 가장 높았고 세포호흡 산물에 대한 정교화 정도가 가장 낮았다. 교과서별로는 교과서 E에서 세포호흡 관련 개념들에 대한 전체적인 정교화 정도가 가장 높았고, 교과서 D에서 가장 낮게 나타났다. 한편, 분석대상 교과서 세포호흡 관련 내용 중 잘못된 정보의 기술, 불분명한 기술, 불충분한 설명 등으로 인해 부분적으로 부적절한 정교화가 이루어져 있는 것이 확인되었다. 세포호흡과 관련된 부적절한 정교화는 교과서를 읽는 많은 학생들이 세포호흡과 관련된 개념을 이해하는 데 있어 장애 요인으로 작용할 가능성이 많으므로 향후 교과서 편찬 시 수정, 보완되어야 할 것으로 사료된다.
