Abstract

The purpose of this study is to analyze the patterns and characteristics of changes in integrated process skills during the process of science high school students' inquiry by using group-based trajectory modeling. 59 students participated in this study. Three hypothetico-deductive inquiry tasks were used as an intervention activity. We asked science high school students to perform those three tasks sequentially and to generate reports of the process and results. We evaluated students' reports by four elements (designing inquiry, collecting data, analyzing data, and forming conclusion) of the integrated process skills according to the scoring rubric developed by Lee and Park (2017), and analyzed the level of changes in integrated process skills in those three inquiry tasks by using group-based trajectory modeling. In addition, we analyzed the characteristics of changes in integrated process skills from several perspectives. The findings are as follows: First, concerning the change patterns of students' integrated process skills, all of the four elements were classified into two groups, but the change patterns were very different by elements. Second, regarding the change characteristics of students' integrated process skills, we found the context-dependency of integrated process skills, variation of learning progression for integrated process skills, and jaggedness of integrated process skills level. Based on these findings, we suggested that a couple of ways be sought to improve the integrated process skills of science high school students.

이 연구의 목적은 집단중심 추세모형을 적용하여 과학고 학생들이 탐구를 수행하는 과정에서 나타난 통합 탐구 기능 변화의 양상과 특징을 분석하는 것이다. 이를 위해 3개의 가설-연역적 탐구 과제를 이용하였으며, 이를 59명의 과학고 학생들에게 순차적으로 수행하게 하고 그 과정을 보고서로 작성하게 하였다. 작성된 보고서는 Lee and Park(2017)에 의해 개발된 평가 준거틀에 따라 통합 탐구 기능 4개 요소별로 평가하였으며, 이를 집단중심 추세모형에 적용하여 탐구 과제를 수행한 3개 시점에 따른 탐구 기능 수준의 변화 양상을 요소별로 분석하였다. 또한, 탐구 기능 변화에서 나타난 특징을 몇 가지 관점에서 분석하였다. 연구 결과는 다음과 같다: 첫째, 집단중심 추세모형을 적용하여 학생들의 통합 탐구 기능 변화 양상을 분석한 결과, 4개 요소 모두에서 2개 집단으로 분류되었으나 그 변화 양상은 요소별로 많은 차이가 있었다. 둘째, 학생들의 통합 탐구 기능 변화에서 나타난 특징을 분석한 결과, 탐구 기능의 맥락의존성, 탐구 기능 발달 경로의 변이성, 탐구 기능 요소별 수준의 들쭉날쭉성을 발견할 수 있었다. 연구 결과를 토대로 과학고 학생들의 통합 탐구 기능 발달을 위한 제언을 하였다.
