초록
이 연구에서는 화학 영역에서 수리 문제 해결과 개념 문제 해결이 서로 영향을 미치는지를 조사하였다. 서울 소재 고등학교에서 사전 화학 성적이 유사한 4학급(N=112)을 선정하여 AC(Algorithmic-Conceptual problem) 집단과 CA(Conceptual-Algorithmic problem) 집단으로 무선 할당하였다. AC 집단의 학생들은 수리 문제 해결에 대한 학습을 수행한 후 개념 문제를 해결하였으며, CA 집단의 학생들은 개념 문제 해결에 대한 학습을 수행한 후 수리 문제를 해결하였다. 연구 결과, 수리 문제 해결에 대한 학습은 관련된 개념 문제의 해결력을 향상시켰으나, 개념 문제 해결에 대한 학습은 관련된 수리 문제의 해결력에 도움이 되지 못하는 것으로 나타났다. 문제 해결에 대한 자신감에서는 수리 문제 해결에 대한 학습이 관련된 개념 문제에 큰 영향을 주지 못했으며, 개념 문제 해결에 대한 학습도 관련된 수리 문제 해결에 대한 자신감에 큰 영향을 주지 못했다.
Abstract
This study investigated whether algorithmic problem solving and conceptual problem solving influenced each other or not. Four classes of 12th grade (N=112) that are equal in prior achievement were randomly assigned to group AC (Algorithmic-Conceptual problem) and group CA (Conceptual-Algorithmic problem). Students of group AC solved the conceptual problems after learning the related algorithmic problems, and those of group CA solved the same problems in reverse order. The results revealed that learning the algorithmic problems improved students' ability to solve the related conceptual problems, but learning the conceptual problems did not help students solve the related algorithmic problems. Regarding the confidence on problem solving, learning the algorithmic problems had little effect on the related conceptual problems. Learning the conceptual problems also had little effect on students' confidence on solving of the related algorithmic problems.
