Abstract

The purpose of this study is to analyze the elementary pre-service teachers' preferred strategies while they solve problems which require number sense and to study a way to improve their number sense ability based on computational thinking. In a survey with 57 elementary pre-service teachers using the instrument consisting of two different number sense components, they preferred much more the rule-based strategies to the number sense-based strategies, which was consistent with the prior studies[13][14][20]. To change this situation, we present a way to improve their number sense ability by utilizing the analyzed results and the nine computational thinking components which were suggested by CSTA and ISTE(2011).

본 연구의 목적은 수감각이 요구되는 문제 해결과정에서 초등예비교사들이 선호하는 전략을 분석한 후, 컴퓨팅 사고력에 기반하여 수감각 능력을 향상시키는 방안을 연구함에 있다. 두 가지 다른 수감각 요소로 구성된 검사지를 이용하여 57명의 초등예비교사들이 선호하는 전략을 분석한 결과, 그들은 수감각 기반 전략보다 규칙기반 전략을 더 선호하였으며, 이러한 결과는 선행연구[13][14][20]과 일치하였다. 이러한 상황을 개선하기 위해, 분석된 결과와 CSTA와 ISTE(2011)의 9가지 컴퓨팅 사고력 요소를 활용하여 수감각 능력을 향상시킬 수 있는 방법을 제시한다.
