Abstract

To learn statistics meaningfully, we must provide an opportunity to experience the process of solving statistical problems with actual data. In particular, exploration questions at the problem setting stage are important for students to successfully guide them from the beginning to the conclusion of the statistical problem solving process. Therefore, in this study, a mixed research method was carried out for the exploration questions of pre-service mathematics teachers during the problem setting stage. As a result, some pre-service mathematics teachers categorized incorrect statistical questions because they did not clearly define the meaning or variables of the questions in the process of categorizing them from possible questions. In addition, questions that cannot be solved statistically were categorized due to misconceptions about statistical knowledge. Second, only 50% of the pre-service mathematics teachers met all 6 conditions suitable for solving statistical problems, while there maining they met only a few conditions. Therefore, the conclusion of this study is as follows. First of all, they should be given the opportunity to experience all the statistical problem solving processes through teacher education because they do not have enough experience in statistical problem solving. Secondly, since the problem setting stage is very important in the statistical problem solving process, a series of subdivided processes are also required in the problem setting stage.

통계를 의미 있게 학습하기 위해서는 실제 데이터로 통계적 문제해결을 경험할 수 있는 기회를 제공해야 한다. 특히 문제 설정 단계에서의 탐구 질문은 학생들이 통계적 문제해결 과정의 시작부터 결론까지 성공적으로 안내하는 데에 중요하다. 이에 본 연구는 문제 설정 단계에서 예비 수학교사들의 탐구 질문에 대해 혼합연구방법을 실시하였다. 그 결과 일부 예비 수학교사들은 통계적 질문을 분류하는 과정에서 질문의 의미나 변수가 명확하지 않거나 통계 지식에 대한 오개념으로 인하여 통계적으로 해결할 수 없는 질문을 분류하였다. 또한 예비 수학교사들의 50%만이 통계적 문제해결에 적합한 6가지 조건을 모두 충족시켰으며, 나머지 50%는 일부 조건만 충족시켰다. 따라서 이러한 결과는 예비 수학교사들에게 교사 교육을 통해 통계적 문제해결 과정을 경험할 수 있는 기회를 제공해야하며, 그 중 문제 설정 단계는 매우 중요하므로 문제 설정 단계도 일련의 세분화된 과정이 필요하다는 점을 제안할 수 있다.
