Abstract

This study investigated university students' conceptual understanding of mechanics and electromagnetism through three grades of students. From the analysis, we found that some students showed misconceptions and sometimes had difficulties in solving problem qualitatively without using mathematics. Also we could identify which test items showed low achievement. In the case of questions about electromagnetism, female students' achievement was lower than male students' achievement, and the freshmen students who have taken physics I or II in high school gained higher achievement. However, this effect was not found for the sophomore and the junior students. We also found which test item's achievement increased according to grade. Even though the questionnaire used in this study was not complete, we hope that the analysis technique could be utilized in further studies if more test items are developed and added to this questionnaire.

본 연구에서는 사범대학생 1,2,3학년생 87명을 대상으로 역학과 전자기 영역에서의 개념적 이해를 조사하였다. 조사결과, 특정 오개념을 보인 문항, 계산없이 개념적으로 해결할 수 있는 문항에서의 어려움, 전반적인 이해부족을 보인 문항들이 발견되었다. 역학정답률은 남학생과 여학생간 차이가 없었으나, 전자기 정답률은 여학생에 비해 남학생이 높게 나타났다. 그리고 고등학교 물리 I이나 II의 수강여부가 정답률에 영향을 준 것으로 나타났다. 그러나 물리 I이나 II의 수강여부에 의한 영향은 대학 1학년생에게만 나타났고, 2,3학년에게는 나타나지 않아, 대학에서의 교육이 고등학교에서의 부족한 부분을 해결할 수 있음을 알 수 있었다. 기본적인 개념문항임에도 불구하고 1학년에서 2,3학년으로 올라감에 따라 정답률이 상승하는 문항이 있어 1학년 과정에서 충분한 지도가 부족했던 개념이 무엇인지 알 수 있었다. 본 연구에서의 평가문항이 역학 및 전자기 개념 이해를 위한 완전한 도구일 수는 없지만, 분석과 해석방법은 앞으로의 관련연구에 널리 활용될 수 있을 것이다.
