Abstract

This study aims to investigate students' statistical thinking through statistical processes in different instructional settings: Teacher-centered instruction vs. student-centered learning. We first developed instructional materials that allowed students to experience all the processes of statistics, including data collection, data analysis, data representation, and interpretation of the results. Using the instructional materials for four classes, we collected and analyzed the data from 57 seventh graders' discourse and artifacts from two different instructional settings using the analytic framework generated on the basis of literature review. The results showed that students felt difficulty particularly in the process of data collection and graph representations. In addition, even though data description has been heavily emphasized for data analysis in statistics education, it is surprisingly discovered that students had a hard time to understand the relationship between data and representations. Also, there were relationships between students' statistical thinking and instructional settings. Even though both groups of students showed difficulty in data collection and graph representations of the data, there were significant differences between the groups in terms of their performance. Whereas students from student-centered learning class outperformed in making decisions considering verification and justification, students from teacher-centered lecture class did better in problems requiring accuracy than the counterpart. The results from the study provide meaningful implications on developing curriculum and instructional methods for statistics education.

본 연구는 실제 자료로 통계적 과정을 경험할 수 있는 교수 학습 자료를 개발하고 수업에 적용했을 때 나타나는 중학교 1학년생들의 통계적 사고를 단계별, 수업형태별로 비교분석하였다. 그 결과 통계적 사고와 수업 형태간의 연관성이 있으며 단계별, 수업 형태별 차이가 나타났다. 향후 통계교육을 위한 교수 학습 모델의 설계와 적용에 유용한 시사점을 제공하였다.
