본 연구의 목적은 음악교사의 교사효능감을 측정할 수 있는 척도를 개발하고 그 타당성을 검증하는데 있다. 이를 위해 먼저 음악교사효능감을 구성하는 직무수행 영역과 구성요인을 탐색한 선행연구를 토대로 음악교사효능감 예비척도를 제작하고 463명의 초·중등 음악교사들의 자료를 수집하여 분석하였다. 그 결과, 최종적으로 5개 영역에서 9개 요인의 총 31문항에 대한 구인타당성이 확인되었고, 최종 척도에 대해 높은 수준의 신뢰도가 산출되었다. 또한 음악교사효능감 척도와 일반적 자기효능감 척도 간의 상관분석 결과는 상관이 높은 것으로 나타나 준거타당도가 입증되었으며, 음악교사효능감은 학교급과 성별에 따라 유의한 차이가 없는 것으로 나타났으나 학력과 경력에 따라서는 유의한 차이가 있는 것으로 나타났다.
The purpose of the study is to develop music teacher efficacy scale and verify its validation. In the process, music teacher efficacy preliminary scale was constructed based on the previous study that had been identified job-related areas that affect music teachers` efficacy and its components in each job-related area. The preliminary scale was administered to 463 elementary and secondary music teachers and the data was analyzed. As a result, a total of 31 items with 9 sub-constructs in the 5 areas was identified by the means of the exploratory factor analyses, thus clearly establishing the construct validity. The overall internal consistency was quite high(Cronbach a =95). In addition, the concurrent validity between this scale and the general self-efficacy scale was established. The overall level of music teacher efficacy was of no significance according to the variables of school and gender; however the overall music teacher efficacy level was of significance according to the variable of education level.
