Development and Evaluation of the Evidence-based Practice Instrument for Physical Educators Teaching Students with Disabilities

국문 초록 (Abstract)

본 연구의 목적은 범이론적 모델을 바탕으로, 장애 학생들에게 근거에 입각한 수업을 진행하기 위한 체육교사의 의 지와 교수법을 측정할 수 있는 측정도구를 개발하고 검증하는 데 있다. 미국 북서부 지역 초.중등학교에서 근무하는 148명의 체육교사들이 본 연구에 참여하였다. 범이론적 모델의 세 가지 개념(자기효능감, 의사결정균형, 변화과정)을 측정하는 문항들의 판별기능을 평가하기 위해 문항분석이 사용되었고, 그 이론적 구조는 확인요인분석을 통해 평가되 었다. 범이론적 모델의 핵심개념인 변화의 단계는 일원분산분석과 다변량분산분석을 사용하여 위의 세 개념들과 비교 되었다. 평가도구의 모든 항목들에 대한 문항판별값과 내적 일치도 값은 우수하거나 매우 우수하게 나타났고, 합당한 설명량(다중상관자승)과 요인적재치를 보였다. 범이론적 모델의 자기효능감, 의사결정균형, 변화과정 구조모형은 부분 적인 타당도가 수립되었다. 향후 본 측정도구의 타당도를 높이기 위해, 큰 표본을 이용한 교차검증법이 유망할 것이다.

The purpose of this study was to develop and validate an instrument based on the Transtheoretical Model (TTM) for assessing physical educators’ intentions and teaching behavior to implement evidence-based practice for students with disabilities. Study participants were 148 physical education teachers who were recruited from both elementary and secondary schools in Northwest regions of the U.S. Item analysis was conducted to evaluate appropriate discriminate functions for items measuring three TTM constructs (self-efficacy [SE], decisional balance [DB], and processes of change [POC]). Internal structures of the TTM items were examined by confirmatory factor analyses. The responses from stage of change were compared to the three TTM constructs. Separate one-way analyses of variance and multiple analyses of variance on each construct by stage were conducted to assess differences among the stages of change. Item discrimination values for all items were good to very good, except for two negative DB items that were deleted. Internal consistencies of SE, DB, and POC were found to be good to excellent. Confirmatory factor analyses showed reasonable squared multiple correlation and factor loading estimates. Three structural models were partially supported by goodness of fit indices. Cross-validation with a large sample size will be desirable to refine this measurement system in the future studies.
