Abstract

We compared algorithmic problem solving and conceptual understanding of chemistry with three types (algorithmic, pictorial- and wordy-formatted conceptual) of problems. The familiarity, confidence, and preference to the three type of problems were also examined. The chemistry problem solving ability test was administered to 228 students from two top high schools in the province of Gyeonggi who were preparing the chemistry examination among the four optional subjects (biology, chemistry, earth science, physics) for enter university. After administrating the chemistry problem solving ability test, the degree of familiarity to some problems and the degree of confidence of their answers in a Likert scale were asked to the students. Besides, the students were asked to place preference to the type of problems in order. The students scored better on the algorithmic problems than on the conceptual problems (pictorial and wordy problems), and were also most familiar with the algorithmic problems. The students were more confident of their answers on both of types pictorial and algorithmic problems, and preferred pictorial problems rather than both of types algorithmic and wordy problems.

본 연구에서는 세 가지 유형의 문제(수리 문제, 그림 문제, 문장 문제)를 이용하여 화학 수리 문제 해결력(수리 문제)과 개념 이해도(그림 문제, 문장 문제)를 비교하고 문제 유형에 대한 친숙도와 자신의 답에 대한 자신감 및 선호하는 문제 유형을 조사하였다. 경기도에 위치한 두개의 비평준화 고등학교 3학년 학생들 중 대학수학능력시험의 선택 과목으로 화학을 선택한 학생들(N=228)을 선별하여 화학 문제 해결력 검사와 문제 유형에 대한 친숙도, 자신감, 선호도 검사를 실시하였다. 연구 결과, 학생들의 수리 문제 성공률이 개념 문제(그림 문제, 문장 문제) 보다 유의미하게 높은 것으로 나타났다. 또한, 학생들은 그림 문제나 문장 문제보다 수리 문제에 더 친숙하다고 응답했다. 자신감에서는 학생들이 문장 문제보다 수리 문제와 그림 문제에 대해 더 자신 있어 하는 것으로 나타났으며, 선호도에서는 그림 문제보다 수리 문제와 문장 문제를 더 선호하는 것으로 나타났다.
