Abstract

We use a scale mainly for quantification when we study the psychological characteristics that we cannot observe. The utilization of a scale is frequent in scientific educational studies. The convenience offered by Likert scale, which is among the most frequently used, enable us to grasp characteristic attitude or recognition in students, and evaluate them against an affective domain. But a lot of errors occur, and has been noted as well in the case of utilizing Likert scale in the process. A central tendency in the utilization of Likert scale appears in this study, and the trend analyzes according to study objects and study contents, but we intend to find a way to utilize Likert scale. The results of study made on our countryside students show that the answers tend to get concentrated and a central tendency appears. Our countryside students were aware of the eyes surroundings them, have respect for elders through social experiences, and have had troubles with differentiated expression or personality in the group and cultural environments. According to the object of study, the central tendency appears more among older students than younger students, more among general students than gifted students. In the contents of study, the central tendency has been given more appearance in scope and their exposure has relatively been in large domain. Therefore when utilizing Likert scale in scientific education study, an error of central tendency appears as if they are results of the study. So, when applying the Likert scale to scientific study, we need to consider sociocultural environment, characteristics of an object and contexts of study. This enables avoiding dependence on numerical value of the utilization results, and interpret them correctly.

일반적으로 연구자들은 관찰할 수 없는 심리적인 특성들을 연구할 때 주로 척도를 이용하여 수량화한다. 과학교육 연구에서도 척도를 활용하는 사례가 자주 나타난다. 특히, 정의적 영역의 평가에서는 학생들의 태도나 인식 등의 특성을 파악하고 평가하기 위하여 척도를 많이 사용한다. 그 중에서 사용이 간편한 리커트 척도를 많이 활용한다. 하지만 리커트 척도의 경우 활용 과정에서 여러 오류들이 발생하여 이를 절대시하는 것은 유의해야 한다. 이에 본 연구에서는 흥미와 태도관련 과학교육 연구에서 리커트 척도의 활용에 따른 중심화 경향을 살펴보고 연구 대상 및 연구 내용에 따라 그 경향성이 어떠한지 분석하였다. 연구결과 연구 대상에 따라서는 대상 학교급 즉, 연령이 높아질수록 중심화 경향이 더 크게 나타났으며, 영재학생보다 일반학생의 경우 중심화 경향이 더 크게 나타났다. 연구 내용에서는 자기노출이 비교적 큰 영역에서 중심화 경향 더 나타났다. 그러므로 과학교육 연구에서도 리커트 척도를 활용할 때 중심화 경향의 오류가 발생하는 것을 알 수 있었다. 따라서 과학교육 연구에 리커트 척도를 활용할 때는 사회문화적 환경과 연구 대상 및 연구 내용의 특성을 고려할 필요가 있다. 또한 리커트 척도를 개선하여 적용해야 하며 나아가 조사 결과의 수치에만 의존하여 해석하는 것을 피해야 할 것이다.
