Abstract

The purpose of this study was to explore the possibility of digital simulation by which pre-service teachers (PSTs) can approximate the core teaching practice of eliciting student thinking. This study examined PSTs' questions to elicit student thinking, their use of "pause" session and peer feedback, and their reflections on doing a digital simulation. We analyzed a two-hour digital simulation session with 13 PSTs who enrolled in the elementary mathematics methods course. The results showed that PSTs shifted their general questions to more content-specific questions throughout the simulation and made a quick transition to comparing students' strategies. The number of lead PST-initiated "pause" ranged one to four times for various reasons. Their peer-coaches did not voluntarily "pause" the simulation session but actively shared what they noticed from the student work samples and suggested the next teaching moves. Without utilizing the pause session, the dramatic improvement of questioning was not observed. Even though the PSTs felt overwhelmed with interacting with the student-avatars in real-time, they highlighted the benefits of simulations, appreciated the opportunity to learn the core teaching practice, and viewed this digital simulation as "real" and "authentic" experience. The findings of this study provide implications for re-designing a practice-based teacher education program.

본 연구의 목적은 예비교사들이 학생 사고를 도출하는 핵심 교수 관행에 근접하도록 돕는 디지털 시뮬레이션의 활용 가능성을 탐색하는 것이었다. 초등 수학교육 방법론을 수강하는 13명의 예비교사들이 참여한 디지털 시뮬레이션을 분석한 결과, 예비교사들은 일반적인 질문에서 내용-특화된 질문을 제기하였으며, 학생들의 해결전략을 비교하였다. 예비교사들은 다양한 이유로 시뮬레이션의 '일시 정지' 기능을 활용하였다. 예비교사들은 학생-아바타와 실시간으로 상호작용하는데 부담을 느꼈지만, 디지털 시뮬레이션을 진정한 교수 경험으로 파악했으며, 그 유용성을 강조하였다.
