이 연구의 목적은 중학생과 고등학생의 사각형에 대한 개념 정의 이해 정도를 분석하고 개념 이미지에 대한 현상을 탐색하는 것이다. 이를 위해 검사 도구를 개발하고 중학교 2학년 60명, 중학교 3학년 63명, 고등학교 1학년 65명을 대상으로 검사하고, 일부의 학생을 면담하였다. 연구 결과는 다음과 같다. 첫째, 학년이 올라감에 따라 자연적으로 사각형의 개념 정의에 대한 이해도가 향상된다고 볼 수 없다. 특히, 모든 학년에서 다른 사각형과 비교하여 마름모 개념 정의에 대한 이해도가 가장 낮은 것으로 나타났다. 둘째, 정사각형에 대한 개념 정의는 여학생이 남학생보다 더 잘 이해하지만, 사다리꼴, 평행사변형, 마름모, 직사각형에 대한 개념 정의에 대한 이해 정도는 성별로 차이가 없는 것으로 나타났다. 셋째, 사각형 개념 정의를 이해하지 못하는 학생은 학년이 올라갈수록 개념 이미지의 영향을 점점 더 크게 받는 것으로 나타났다. 넷째, 학년이 올라갈수록 학생의 사각형에 대한 개념 이미지 형성에 개념 정의의 영향은 줄어들고 교과서나 교사의 영향이 증가하는 경향을 보여주었다.

본 연구는 다양한 홍보매체를 접하고 있는 우리나라 중학생을 대상으로 금연홍보노출정도와 흡연과의 관련성을 살펴보고자 한다. 연구의 대상은 2007년 청소년건강행태온라인조사에 응답한 중학생 38,820명으로서 이 중 설문에 대한 불충분한 응답으로 지난 일 년 동안 접한 금연홍보매체와 흡연율을 평가할 수 없는 1,106명을 제외한 37,714명을 최종 분석 대상자로 하였다. 통계 프로그램은 SPSS version 17.0을 이용하였다. 연구 결과 흡연율은 학년이 올라갈수록 증가하였고, 대상자의 특성에 따른 흡연율은 1학년에서 성별, 거주 지역, 학업성적, 경제상태, 부모와 동거여부, 스트레스 정도, 현재음주여부, 금연교육경험, 금연홍보매체노출 정도에 따라 유의한 차이가 있었다. 2학년에서는 거주 지역을 제외한 변수에서 유의한 차이를 보였고, 3학년에서는 거주 지역과 금연교육경험을 제외한 변수에서 유의한 차이를 보였다. 대상자의 금연홍보매체노출이 흡연과 관련된 제 변수를 통제한 상태에서 독립적으로 유의한 변수인지 파악하기 위하여 로지스틱 회귀분석을 실시한 결과 1학년의 경우 금연홍보매체노출이 전혀 안 된 군을 기준으로 하였을 때 5~6점이 교차비 0.49(95% CI=0.33-0.74)로 유의하게 낮았고, 3학년의 경우 5~6점이 교차비 0.57(95% CI=0.43-0.76)로 유의하게 낮았다. 결론적으로 우리나라 중학생에서 금연홍보매체 노출정도와 흡연과의 관련성을 파악할 수 있었고, 추후 선후 관계나 다양한 매체를 활용한 효과적인 메시지 전달을 위한 금연광고 개발에 있어 심도 있는 연구가 필요할 것이다.

The purpose of this study was to investigate the levels of the adolescents' self-concept, communication, and conflict with parents, and to examine relationship between adolescents' conflict and their communication. This study also investigated the effect of the conflict and the communication on their self-concept. 179 second graders of 3 middle schools and 182 6th graders of 2 elementary schools of East Jeonnam were selected as the subjects. The questionnaires for the communication and the conflict between the adolescents and the parents and the self-concept inventory were used. The data were analyzed by regression analysis, t-test, paired-t-test, one way ANOVA and Duncan analysis. First, mother was better than father in the communication with the adolescent. The conflicts with the parents were as shown below in order; the homework, school record, sibling relationship, playing computer games, etc.. The adolescents' self-concept was above the median. Second, the adolescents' conflicts and communications with parents were negatively correlated. Third, there was a difference in the adolescents' self-concept according to the conflict with the parents. Fourth, the adolescents' self-identity was influenced by the communication with the parents. Their self-acceptance was highly influenced by the conflict and the communication with the parents. Their self-behavior was influenced by the communication with the parents.

변화하는 시대에 잘 적응할 수 있고, 새로운 시대를 창조할 수 있는 교육이 이루어져야 한다. 이러한 교육의 필요성에 의해 중학생들의 과학창의력 신장을 위한 발문지를 개발하였다. 본 연구에서는 중학교 3학년 과학 7단원 태양계의 운동 중 14개의 주제를 추출하여 총 146개의 발문을 개발하였다. 중학교 3학년 142명을 실험집단과 통제집단으로 나누어 발문지를 약 5주간에 걸쳐서 투입하여 과학창의력과 학업성취도의 변화를 알아보았다. 과학창의력과 학업성취도 모두 유의미한 결과가 나왔다. 발문지 활용 수업이 학생들이 창의적으로 사고하는 학습 활동을 이끌어 내는데 용이하게 작용한 것으로 해석된다. 그러므로 발문지 활용 수업이 학생들의 창의력 신장을 위한 방법으로 사용될 수 있다.

학생들은 어떠한 과학 탐구 문제를 적절한 것으로 생각하는지 조사하기 위하여, 서울 소재 중학교 1학년 중 과학 성적이 상위 1/3 안에 해당하는 105명을 연구 대상으로 선정하고, 이 학생들에게 자신들이 수행할 탐구 문제를 스스로 설정하게 한 다음, 이를 모두 수집하여 제시하고 각각의 문제에 대하여 적절한지 여부를 5단계 리커트 척도를 사용하여 평가하도록 하였다. 탐구 수행전 평가에서는 탐구 문제에 과학적 용어나 주제가 포함되는가, 쉽게 경험하기 어려운 내용이나 소재가 포함되는가, 원인과 결과의 인과적 관계를 질문하는가 등을 적절한 탐구 문제라고 하였다. 탐구 수행 후 탐구 문제가 변경된 학생들에게 그 이유를 조사한 결과 '실행 가능성'을 또 다른 준거로 생각함을 알 수 있었다.

The main purpose of this thesis was to provide a basis to investigate the effectiveness of regular exercises on basic physical fitness for middle school students. 40 second graders from a middle school were chosen randomly and divided into 4 groups-wrestling group, basketball group, jogging group, and control group. The first three groups have been trained 4 times per week for 18 weeks after class to be compared with the comparison group. Pre and post measurements of physical fitness of the subjects were processed by means of the SPSS program. The average and the standard deviation of the measurements of each group were covered with the ANOVA test, according to the periods and the types of training. Duncan's Multiple Range Test was performed to identify the significance of the relationship between training period and improvement in basic sports ability. The conclusions as follows; 1. In the 50 meter sprint, only the wrestling group showed statistical significance, while the other groups showed gradual progress in general. 2. In the standing long jump, there is no group that showed any improvement. 3. In the forward flexion of the trunk, no significance was to be found. 4. In 30-second sit-ups, the wrestling group showed statistical significance. The wrestling group made greater progress than the other groups, and the basketball group and the jogging group also showed rather great progress. 5. In push-ups, statistical significance was found in the groups of wrestling, basketball, and jogging. And the wrestling group came in first, the basketball group second, and the jogging group third on the progress level. 6. In the distance run, the jogging group showed statistical significance and the jogging group made considerable progress. Steady improvement was to be found in the groups of wrestling and basketball.

The purpose of this research is to find out if it is possible to apply the Waldorf School's mathematics education method to Korean alternative schools which are run under the national curriculum. To achieve this, the researcher conducted class on geometry for three weeks with ten 7th graders(four girls and six boys) from Apple Tree Waldorf alternative school in Busan, which has adopted Valdorf education courses. For the first two weeks, the class was about 'fundamental geometrical construction', and then it was evaluated. On the third week, the lesson was on plane figures, followed by a test with 9 plane figure questions that are based on general middle school mathematics curriculum. The result shows that most of the students understood 'fundamental geometrical construction'. When it comes to the test on 'plane figures', seven students got 8 out of 9 right, two students got 6 out of 9 right, and one of them had difficulty solving the questions. According to the results of this research, it is thought that there will be no problem for students to understand mathematical concept even if the Waldorf School's mathematics education method is applied to Korean alternative schools. Also, the Waldorf School's mathematics education method is considered to be a good teaching model for the Korean mathematics curriculum which places emphasis on 'mathematical creativity' in regard to the curriculum and contents.

The purpose of this study was to find out the relationships among the eating behavior, the nutrition knowledge & the physical growth, and factors influencing each of them in middle school students. Eight hundred three boys and girls, who were sampled from the third graders of 6 middle schools located in Taejeon and Ahnmyeondo, were asked to fill out the questionaire. The statistics used for data analysis were Frequency, Percentage, Oneway, Crosstabs, Chi-square($X^2$), t-test, Pearson Correlation, Regression, and Path analyses. The results are summarized as follows: I. The asked students showed the significant difference in frequency intaking food and the eating attitude depending on sexual distinction and area. The girls got higher frequency score(intaking food) than the boys did and the students in Taejeon got better eating attitude score than those in Ahnmyeondo. Also, the girls got higher nutrition knowledge score than the boys did and the students in Taejeon got higher nutrition knowledge than those in Ahnmyeondo. 2. The higher the economic level was, the higher the frequency score(intaking food) was. Also, the students whose father had the occupation involved in the tertiary industry and better school ing made higher nutrition knowledge, eating attitude, and frequency intaking food than others. The students whose father had the occupation involved in the tertiary industry and better schooling were taller and heavier than others. 3. The variables influencing on the frequency intaking food were father's school ing, father's occupation, economic level, sexual distinction, eating attitude. The variables influencing on eating attitude significantly was only the birth order. The variables influencing on the height were sexual distinction, residential area, eating attitude, frequency intaking food, father's schooling. Also, the variables affecting the weight were sexual distinction, father's schooling, eating attitude, frequency intaking food.
