고등학교 생물 교과서에서의 진화내용분석 = Analysis of Evolutionary Content in High School Biology Textbook

다국어 초록 (Multilingual Abstract)

This study analyzed the evolutionary content in 13 textbooks developed from the first to the 6th high school biology curriculum. The content analysis of textbooks, which were delineated nine component, was performed on the 80 evolutionary categories. According to the result, the proportion of the total evolutionary content in textbook increased from the textbooks developed by the 1st curriculum to the textbooks developed by the 6th curriculum, but the proportion of `main narrative` in total evolutionary content was gradually decreased. It also showed that biology curriculum and points of view of textbook writer influenced on the proportion of evolutionary contents. On the whole, the topics of analysed textbooks exhibit insufficient diversity. Any categories- `group selection`, `gene selection`, `gaps in fossil record`, `co-evolution`, `punctuated equilibrium`, `mosaic evolution`, `place of labor in human evolution`, `human race differentiation`, `criticism of ontogeny recapitulates phylogeny ` and `human activities affecting evolution`- were not treated and others - `theory of neutralism`, `theories of major episodes(excepting extinctions) found in the geologic time scale`, `sympatric speciation`, `clinal and area-effect speciation`, `polyploidy and evolution`, `gradualism` and `evolution and origin of mammals` - were treated very lightly, the most emphasized topic was `phylogeny in general` and `formation of precells`, `miscellaneous` in the order of emphasis. `Theory of natural selection` was lightly treated as just one of evolutionary theory though it should be emphasized as major theme of evolution. Also, the law of recapitulation, of witch biologists doubt the validity, was discussed as an evidence of evolution in some textbooks. And the agents of genetic equilibrium disruption ike genetic drift and migration were treated as of little importance. On the basis of above result. it was suggested that the textbook writers introduced the more meaningful evolutionary topics focused the theory of natural selection in explanation of evolution and evolution theory.
