This research analyzed elementary pre-service teachers' perception on the importance and performance of major factors that constitute good instruction, and attempted to find ways to improve pre-service teacher education. A survey was conducted to 157 pre-service teachers who were senior students at a university. The questionnaire consisted of four main areas of good instruction and major factors for each area, and the importance and performance of each factor were answered on a 5-point scale. As the result of the t-test on the difference between importance and performance, significant differences were found between the importance and performance of all 24 factors. In addition, the importance-performance analysis showed that there were 3 factors to be concentrated for the improvement, 9 factors to be kept up because of their good work, 9 factors to have low priority, and 3 factors to avoid excessive effort. Based on the results, the research proposed issues to be considered in organizing and operating the elementary pre-service teacher education program.

본 연구의 목적은 수업의 효과를 측정할 때 수업평가 설문을 통하여 각 질문의 단순한 결과를 나열하여 비교하기보다, 수업평가 설문의 모든 질문에 대한 요인분석 (Factor Analysis)과 AHP (Analytic Hierarchy Process) 방법을 이용하여 수업효과의 측정을 보다 효과적으로 할수 있는 방법을 제시하고자 한다. 따라서 본 연구는 미국 경영학부 학생들의 수업평가 설문에 대한 요인분석 결과와 동일한 수업평가 설문을 이용하여 숭실대학교 경영학부 학생들의 요인분석 결과를 분석, 비교하였다. 또한 AHP를 이용하여 한국학생들의 수업효과에 대한 이들 요인들의 상대적 가중치를 조사함으로써, 수업효과 향상을 위한 주요한 요인들을 찾고자 하였다. 본 연구의 수업평가 측정에 사용된 설문지는 조지아 주립대학에서 사용하고 있는 UC-Berkely Instrument로 1(전혀 그렇지 않다)부터 5(매우 그러하다)의 5점 척도를 이용한 33개의 질문항목으로 이루어져 있다. 미국 조지아 주립대학 경영학부 학생들의 요인분석 결과는 다음과 같은 6개의 요인으로 나누어져 있다. (Appendix A): (1) Organization and Clarity, (2) Communication Ability, (3) Grading and Assignment, (4) Interaction with Student, (5) Intellectual/Scholarly, and (6) Student Motivation. 숭실대학 경영학부 학생들의 요인분석 결과는 미국의 경우와는 달리, (1) 수업준비 및 강의방법, (2) 시험 및 성적평가, (3) 비주입식 교육방법, (4) 교수-학생간의 인간적인 관계, (5) 숙제 및 과제물과 같은 5가지의 요인으로 구성되어진 것으로 분석되었다. 특히 한국학생을 대상으로 하여 AHP를 이용하여 각 요인들의 수업효과에 대한 상대적 가중치를 조사하였다. 특이한 결과는, 미국학생의 경우 수업준비 및 강의 방법이 상대적으로 중시된 반면, 한국학생들은 미국학생들이 비교적 덜 중시하는 교수-학생간의 인간적인 관계가 수업효과를 높이는데 가장 큰 기여를 하는 것으로 나타났다. 본 연구는 한국 문화의 특징이라 할 수 있는 교수-학생간의 인간적인 관계가 중시되는 교육환경하에서, 정보화 사회의 한 수업형태인 재택수업을 외국(특히 미국)의 방법을 그대로 따라 실시할 경우, 많은 부작용이 있을 수 있다는 것을 암시하며, 따라서 우리 교육문화에 맞는 재택수업 형태의 개발이 시급함을 제시한다고 하겠다.

Background: School is a primary health education setting for adolescents and the continuous support should be provided to renew school health education curriculum correspondent to cultural changes in Korean society. Objectives: This study was conducted to identify the principals and teachers' health education needs for their students and to analyze their conceptual map for health education curriculum at school. Methods: The sample size of the preliminary study was 321 of the teachers in elementary, middle, and high school, and that of the main study was 355 middle school principals and teachers over the country. The self-administered mailing survey was conducted to collect the available health education topics in the preliminary study, to identify the factor structure of the health education topics and to analyze the conceptual properties on health education with exploratory factor analysis and multidimensional scaling analysis in SPSS 12.0. Results: A total of 21 health education topics were collected from the preliminary survey and 31 topics were, comprehensively, generated for the main survey. In exploratory factor analysis, seven factors were generated in 1.0 or greater Eigen value standard. The seven factors were 'life health promotion,' 'disease prevention and drug control,' 'bulling and aggression prevention,' 'injury and sexual harassment prevention,' human-efficacy and regulation,' 'health protection for adolescence,' and 'alcohol and tobacco control.' The educational need scores were the highest in 'human-efficacy and regulation' and 'injury and sexual harassment prevention.' The two-dimensional cooperates were generated for the 31 health education topics and the two dimensional properties which divided the conceptual space were 'health-safety' for one and 'public/environmental-individual/personal' for the other. That is, middle school principals and teachers primarily, understand the health education curriculum in the sense of 'health vs. safety' and 'public/environmental vs individual/personal.' Conclusions: Health education curriculum and textbook should be developed based on teachers' needs and conditions for health education in school fields. The field-based health education programs or textbook would make more possible problem-solving health education for youth in real school fields.

This article presents new perspectives for classification of students' mathematical errors on the basis of experiential structuralism. Experiential structuralism's mechanism gives us new insights on mathematical errors. The hard core of mechanism is consist of 6 autonomous capacity spheres that are responsible for the representation and processing of different reality domains. There are specific forces that are responsible for this organization of mind. There are expressed in terms of a set of five organizational principles. Classification of mathematical errors is ascribed by the theory to the interaction between the 6 autonomous capacity spheres. Different types of classification require different autonomous capacity spheres. We can classify mathematical errors in the domain of linear function problem solving comparing cognitive psychological mechanism of experiential structuralism.

This paper investigates the teaching and learning of Linear function relating functional contexts and suggests the improved methods of representation-shift through this analysis. The methods emphasize the link between students' preacquired knowledge of mathematical representations and the way of using those. This methods are explanatory teaching, teaching and teaming based on modelling perspectives or tasks (interpretation, prediction, translation and scaling). We categorize the 8th grade middle school students' errors on the linear function relating real contexts and make a comparative study of the error-remedial effects and the teaching and teaming methods. We present the results of a study in which representation-shift methods based on modelling perspectives and tasks are more effective in terms of flexible connection of representations and error remediation. Also, We describe how students used modelling perspective-taking to explain and justify their conceptual models, to assess the quality of their models and to make connection to other mathematical representation during the problem solving focusing on the students' self-diagnosis.

In this paper, we analyzed the characteristics of the gender difference with the results of National Assessment of Educational Achievement(NAEA) from 2004 to 2006, which subjects are 3rd, 9th and 10th graders. First, we analyzed the characteristics of the achievement by the scale scores, according to years, achievement standards, grades. Second, we surveyed the number of items and ratio which male/female prevails and its characteristics according to grades, difference levels, content areas(i.e., numbers and operations, figures, measurement, probability and statistics, letters and formulas, patterns and function). Furthermore, we perform in-depth analysis of the items which gender difference in correct response proportion is more than 7% and analyze the cause of gender difference of achievement. This paper provides large valid data about gender difference by the results of NAEA. It can give suggestions with regard to policy making.
