초록
양적 연구의 테두리 안에서 장애에 대한 연구는 피험자의 수가 매우 제한되어 있고, 그들의 변이성이 매우 크고, 표준화된 검사가 부족하기 때문에 매우 도전적인 연구 분야이다. 적절한 연구 설계를 효과적으로 이용하기 위해서는 여러 가지 대안적이며 보완적인 방법을 고려해 볼 필요성이 있다. 본 원고는 이러한 내용들에 대해 고찰하였다. 즉, 양적 연구에 의해 노출되고 있는 여러 가지 문제점들을 해결하기 위해 양적 연구의 테두리 안에서 변화시킬 수 있는 변인들에 대해 살펴보았다. 양적 연구와 질적 연구가 패러다임이 되어서는 안 될 것이다. 양적 연구와 질적 연구는 단순히 연구방법을 의미하는 것이다. 우리는 지금 적어도 연구라는 세계에서는 포스트 패러다임의 시대로 접어들고 있다.
Abstract
Best practice in service delivery system of adapted physical activity should be informed by current research findings. However, traditional research methods are not always geared to address some of the complex and individuals questions that arise in adapted physical activity intervention because of small sample size, large variability, lack of standardized tests, and difficulty to generalize the study results. Based on criticisms of using the statistical significance tests as the sole criterion for evaluating the overall significance of research findings, the article explores several recommendations for evaluating and reporting research findings such as reporting effect size and establishing a larger alpha level.
