현대물리 주요 개념에 대한 대학생들의 인지 경향

Abstract

본 연구는 현대물리학 분야에서 알아야 할 중요개념인 기본 힘과 입자, 강력과 결합에너지, 불확정성원리에 대한 학생들의 이해 수준과 인지 경향 을 조사함으로써 대학생들이 갖고 있는 오개념의 대한 경향성을 알아보는데 그 목적이 있다. 이를 위하여 서울 소재 3개의 대학교에서 물리와 물리교육을 전공하는 대학생을 대상으로 두 차례에 걸쳐 설문조사를 실시하였다. 연구 결과분석은 학교별, 학년별, 전공별, 이수 교과목별 현황 차이에 따라 중요한 현대물리 개념에 대해 학생들이 갖고 있는 오개념 유형과 인지 경향성을 찾는데 초점을 맞추었다.;The purpose of this study was to analyze university students' cognitive level and misconception tendency about the important conceptions related to modern physics: the fundamental forces and particles, the strong force and nuclear binding energy and the uncertainty principle. Therefore to do this study, university students who majored in physics and physics education in Seoul were sampled as the subjects of this questionnaire research. The primary questionnaire which consists of 10 response questions was executed to 135 students and the secondary questionnaire which consists of 22 multiple-choice questions inclusive of subordinate items was executed to 122 students. After collection, SPSS Win 13.0 program was adopted for the statistical analysis of questionnaire. The main misconception tendency about the important conceptions related to modern physics was found in this study were as follows: Students' cognitive level on the fundamental forces and particles showed low against expectation. And they have a great notion that all of the electron, proton and neutron in an atom is the fundamental particles or not. Students' cognitive level on the nuclear binding energy is good altogether but students have the misconception tendency on a mass defect as a result of nucleons packing effect. Students' cognitive level on the uncertainty principle is good altogether but students' cognitive level on a duration of events and conservation of energy is lower than other questions.
