Abstract

This study aimed to investigate pre-service science teachers' perceptions of significance and usefulness of evolution and genetics. To this end, 82 pre-service biology teachers and 159 non-biology science teachers answered the items to measure the perceptions of significance and usefulness of evolution and genetics. The validity and reliability were examined using Cronbach alpha, two-dimensional rating scale model Rasch analysis, and factor analysis. The finding illustrated that the test items met the benchmark to be valid and reliable test items. Second, pre-service teachers' perception of significance and usefulness of evolution was independent to that of genetics. The level of pre-service teachers' perception of significance and usefulness of evolution was lower than the level of genetics. Lastly, the levels of pre-service teachers' perceptions of significance and usefulness of evolution and genetics were not significantly different across academic years and majors (biology and non-biology). The findings of this study stressed the importance of teaching significance and usefulness of evolution and genetics in pre-service science teacher education program.

이 연구는 예비과학교사들이 진화학과 유전학에 대한 학문적, 실용적 가치에 대한 인식을 조사하기 위하여 이루어졌다. 이 연구를 위하여 82명의 예비생물교사와 159명의 비생물전공 예비과학교사가 참여하였다. 5단계 리커트 척도로 된 진화와 유전에 대한 학문적 가치에 대한 4개 문항과 실용적 가치에 관한 5개 문항에 대한 응답을 수집하여 분석하였다. 문항의 타당도와 신뢰도는 내적일관성신뢰도, 이차원평정척도 라쉬모델 분석, 요인분석으로 이루어졌다. 연구 결과, 먼저 이 연구에 사용한 문항에 대한 라쉬모델 분석과 다양한 분석에서 문항의 타당도는 기준에 만족하는 것으로 확인되었다. 두 번째로 진화에 대한 학문적, 실용적 인식에 대한 차원은 유전학과 차별적인 것으로 확인되었다. 세 번째 예비생물교사가 가지는 인식의 수준은 비생물전공 예비과학교사와 차별성이 없었다. 예비생물 교사들은 진화와 유전학에 대한 학문적, 실용적 가치에 대한 이해를 높여야 함을 확인하였고, 이 연구에서 사용한 문항이 해당 구인을 조사하는데 적절하게 활용할 수 있음을 확인하였다.
