Abstract

The purpose of this study is to understand the characteristics of the mathematical modeling tasks and lesson designs developed by pre-service teachers based on the inherent awareness of mathematical modeling, considering the importance of creating a task to perform mathematical modeling activity and designing a lesson. As a result, the mathematical modeling tasks developed by pre-service teachers mainly presents an appropriate amount of information using real life contexts for the purpose of learning using concepts, and it showed a tendency to develop to the level of cognitive demand that required procedures with connections to understanding, meaning, or concepts. And most of the developed modeling task-based lessons showed a tendency to design warm-up activity, model-eliciting activity, and model-exploration activity. This result is due to the lack of experience of pre-service teachers in creating mathematical modeling tasks. Therefore, it is necessary to continuously provide opportunities for pre-service teachers to learn concepts or create mathematical modeling tasks intended for exploration according to various mathematical contents, thereby actively cultivating their ability to create modeling tasks in the course of training pre-service teachers. Furthermore, it is necessary to strengthen the expertise in mathematical modeling teaching and learning by providing opportunities to actually perform the mathematical modeling-based classes designed by pre-service teachers and to experience the process of reflecting on the lessons.

본 연구는 수학적 모델링 활동을 수행할 수 있는 과제 개발과 이를 기반한 수업 설계의 중요성을 생각하여, 수학적 모델링에 대한 예비교사들의 내재된 인식을 바탕으로 그들이 설계한 수학적 모델링 기반 수업의 특징을 파악하는 데 목적이 있다. 그 결과 예비교사들이 개발한 수학적 모델링 과제는 주로 개념 활용 학습을 목적으로, 실생활 맥락의 소재를 활용한 적정량의 정보를 제시한 다소 구조화된 형태로, 이해, 의미, 개념과 연결이 있는 절차적 과정이 필요한 인지적 요구수준으로 개발된 경향을 보였다. 이를 바탕으로 설계한 수업은 대부분이 준비 활동, 모델 도출 활동, 모델 탐험 활동만을 유도한 경향이 있었다. 본 결과를 토대로 예비교사 교육에서의 시사점을 논의하였다.
