본 연구는 뇌반구 이론에 입각해 뇌반구 우세성에 따라 학업성취, 자아개념 및 성취동기의 차이를 밝히고자 하였다. 연구대상은 대전광역시 소재 고등학교 1개교의 2학년 학생 189명이었다. 본 연구에서는 측정도구로 뇌반구 우세검사, 자아개념 검사, 성취동기검사를 사용하였다. 뇌반구 우세성은 좌뇌 우세형, 우뇌 우세형, 전뇌형 세집단으로 분류하였다. 주된 연구 결과는 다음과 같다. 우뇌 우세형이 좌뇌 우세형 및 전뇌형에 비해 학업 성취도 및 능력에 대한 자아개념이 낮게 나타났다. 우뇌 우세형이 좌뇌형에 비해 성취동기가 낮게 나타났다. 이런 결과는 현재 학교에서 수리, 논리 중심의 좌뇌형 주제, 과목에 초점을 맞춘 교육을 하기 때문인 것으로 생각된다.

The purpose of this study is to investigate affective factors that distinguish the high spoken English use group from the low spoken English use group among Korean EFL middle school students. This study focuses on the variables of communication strategy, willingness to communicate, self-concept, motivation, and anxiety. A questionnaire on communication strategy, willingness to communicate, self-concept, motivation, anxiety, and the use of spoken English was designed and administered to 112 students of eighth grade in a province. The findings of the study are as follows: (1) the middle school students’ levels of extrinsic motivation and speaking anxiety were high, while the levels of self-concept, intrinsic motivation, and the use of spoken English were low, (2) the highest positive relationship was found between willingness to communicate (WTC) and the use of spoken English, while the highest negative relationship was observed between speaking anxiety and the use of spoken English, (3) willingness to communicate (WTC), academic self-concept, and communication anxiety were statistically significant factors that distinguished the high spoken English use group from the low spoken English use group. Based on the findings, some suggestions were made in regard to helping students improve their use of spoken English.
