Abstract
This study is to investigate the change of intelligent and affective domains through the student self-evaluation to identify causes of wrong answers. Through this evaluation, students could have opportunities to solve the given mathematical problems basically and to reflect their problem-solving process, and further to recognize which mathematical content(concepts or expressions, symbols, etc.) led them to solve the problems incorrectly or wrong. Through this process, they would correct their wrong process and answers and to reinforce the prerequisite knowledges relevant to the problems, and furthermore, to enhance problem-solving abilities. To accomplish this, this study was executed as a case study on the subject of four tenth graders. The subject consisted of two boys and two girls. In this study, three essay types of mathematical problems in tenth grade level were chosen from several domestic tests in Korea. Based on the original three essay type of problems, three types of similar problems, namely equivalent problem, similar problem, and isomorphic problems were reconstructed, respectively by the researchers. The subjects were guided to solve the original three problems, and they corrected their wrong parts of the first problem of the three problems. They solved an equivalent problem of the first problem and executed self evaluation and also corrected wrong parts. Next, they dealt with a similar problem of the first problem and executed self evaluation and also corrected wrong parts. Next, while dealing with an isomorphic problem of the first problem, the subjects did the same things. Thus, for the second and third original problems, the study was implemented in the same way. To explore their intelligent and affective domains through student self-evaluation in-depth, the subjects were interviewed formally before and after conducting the experiment and interviewed informally two times, and the recordings were audio-typed.
본 연구는 오답원인 자기평가와 유사 문제에 관련된 선행 연구를 바탕으로, 학생들이 자신의 학습 과정을 반성할 수 있는 하나의 방안으로 오답원인 자기평가를 실시하고 유사한 문제들을 해결하는 과정을 통해 학생들의 인지적, 정의적 영역의 변화를 살펴보고자 한다. 이를 위하여, 본 연구에서는 고등학교 1학년에 재학 중인 네 명의 학생들을 대상으로 근원 문항 3개를 제시하고 각각에 대한 유사 문항들을 유형별로 제시하여 오답원인 자기평가를 작성하게 하고, 이와 더불어 사전 면담과 사후 면담, 그리고 두 차례의 비공식 면담을 실시하였다. 한 마디로, 본 연구에서는 연구 대상자들로 하여금 오답원인 자기평가지를 이용하여 유사 문항들을 해결하고 오류 원인을 점검하는 반성 활동을 거치면서 자신의 문제점을 스스로 판단하며 문제 풀이 과정의 변화와 수학 학습 태도의 변화를 살펴보고자 한다.
