본 연구는 수학 선행학습에 대한 초등학교 교사의 인식을 분석하고 그것이 수학 선행학습에 대처하는 초등교사의 수업 운영 방식에 어떤 영향을 주는지 조사하는데 그 목적이 있다. 본 연구를 위하여 204명의 서울특별시 공립 초등학교 교사를 대상으로 설문조사를 실시하였고, 양적연구를 보완하기 위하여 5명의 교사를 대상으로 심층 면담을 실시하여 질적 자료를 수집 및 분석하였다. 이를 통하여 초등학교 교사들은 수학 선행학습이 학교 수학 수업에 부정적인 영향을 미친다고 생각하고, 수학 선행학습은 수학 개념의 이해보다는 수학 공식의 암기와 문제 풀이에 있다고 보며, 학교 수학 수업에 대한 흥미에 미치는 영향에 대하여 부정적으로 인식하고 있음을 알 수 있었고, 수학 선행학습이 학생에게 미치는 영향에 대하여 교사들은 학생들의 전반적인 수학 수업 태도에 부정적인 영향을 미친다고 인식하고 있었다. 또한 초등학교 교사들은 수학 선행학습이 수학 수업에 대한 사기를 떨어뜨린다고 인식하며, 자신의 수학 수업 방식에도 영향을 미친다고 생각하고 있었다. 이런 결과를 토대로 학교현장교육에 대한 몇 가지 시사점을 제안하고자 한다.

The purpose of this study was to investigate the measurement equivalence and to suggest application ways in teaching aptitude and personality test results for pre-service mathematics teachers between a graduate school of education and a college of education. This study analyzed the scores of the teaching aptitude and personality test of 36 pre-service mathematics teachers enrolled in a graduate school of education and 111 pre-service mathematics teachers in a college of education by performing a multivariate generalizability analysis. The main results were as follows. First, graduate's pre-service mathematics teachers had a higher level of teaching aptitude and personality than that of college's pre-service mathematics teachers based on the total scores. In addition, graduate's pre-service mathematics teachers had higher levels of teaching aptitude and personality than those of college's pre-service mathematics teachers except for a creativity application domain based on the sub-domain scores. Second, cognitive domains were measured more precisely but affective domains were measured less precisely for graduate's pre-service mathematics teachers than for college's pre-service mathematics teachers. Third, regardless of school levels, Cronbach's ${\alpha}$ values, which might be overestimated by applying the classical test theory, were higher than dependability coefficients. Fourth, this study showed a somewhat negative result in ensuring the measurement equivalence for a problem solving exploration domain. However, regardless of school levels, this study indicated that the overall measurement was generally reliable on composite scores. Based on these results, it was confirmed that multivariate generalizability methodologies' approach can be useful for exploring the measurement equivalence issues. Finally, this study suggests how to utilize the results of the test, how to apply a multivariate generalizability analysis for detecting the measurement equivalence, and how to develop future research based on limitations.

The purpose of this study was to analyze pre-school teachers' observation experience and their pre and post degrees of preferences in observing underground and water living things, fungus, insects, flowerless plants and sea lives. Based on the analysis, their pre-observation experience in living things were insects, ocean creatures, underground living things, flowerless plants, fungus and water living things in order. The degree of preferences in flowerless plans based on their gender, the female pre-service teachers showed higher scores than the average in both pre and post test. The male, however, responded higher scores in underground living things in both tests. Their background such as liberal arts or science or arts and physical major affected their preferences scores in water living things, insects and flowerless plans in the post test, and the science major pre-service teachers showed the highest degree of preferences in insects among the liberal arts, science or arts and physical major pre-teachers in the post test. In conclusion, there were different degree of their preferences affected by the pre observation experience, gender difference, their present majors such as the liberal arts, science or arts and physical major, the categories of living things but not in their high school background such as liberal arts or science.

Based on the finite element method of traditional straight Euler-Bernoulli beams and the coupled relations between linear displacement and angular displacement of a pre-twisted Euler-Bernoulli beam, the shape functions and stiffness matrix are deduced. Firstly, the stiffness of pre-twisted Euler-Bernoulli beam is developed based on the traditional straight Euler-Bernoulli beam. Then, a new finite element model is proposed based on the displacement general solution of a pre-twisted Euler-Bernoulli beam. Finally, comparison analyses are made among the proposed Euler-Bernoulli model, the new numerical model based on displacement general solution and the ANSYS solution by Beam188 element based on infinite approach. The results show that developed numerical models are available for the pre-twisted Euler-Bernoulli beam, and which provide more accurate finite element model for the numerical analysis. The effects of pre-twisted angle and flexural stiffness ratio on the mechanical property are investigated.

This study aimed to identify ways to implement pre-parent education for adolescents in regular classes at school. This was achieved by investigating whether the contents of the 2015 revised curriculum high-school technology and home economics textbooks reflected the goals of pre-parent education. The main texts and activities of chapters with 'preparing for parenthood' in the title from 12 high-school technology and home economics education textbooks were analyzed with respect to the three pre-parent education goals of developing perceptions and attitudes toward parenthood, learning parenting knowledge and skills, and reinforcing parental capacity. The results were as follows. First, textbook contents and activities reflected the three goals of pre-parent education in a balanced manner. Second, both the contents and activities of textbooks tried to motivate students to perceive parenthood and parenting through reflection on their relationship with their own parents. Third, because the textbooks encouraged students to consider parenthood and parenting, they acknowledged the importance of undertaking pre-parent education to reinforce their parental capacities. Using such textbooks in regular technology and home economics classes is expected to provide students with an opportunity to consider parenthood and shape their perceptions and attitudes accordingly, thereby allowing adolescents to prepare themselves for parenthood and become good parents.

This study investigated pre-service elementary school teacher's perception of science curriculum use in Korea and Japan. Ninety four pre-service elementary teachers in Korea and fifty three pre-service elementary teachers in Japan are participated in this study. As the result, four patterns were revealed. First, science isn't perceived as an important or interesting subject by the pre-service elementary teachers in both countries. Second, the perception of Korean pre-service teachers about the objectives of science subject is relatively negative. Third, in the case of Korea, the perception about the effectiveness of science subject content and level, and the amount of learning is shown to be more negative than those of Japan. Finally, in both countries, the science majors and the non-science majors have negative perceptions about the inclusion of the perspectives and methods of assessment and the preparation of teaching and learning plan in curriculum.

Based on the coupled elastic bending deformation features and relationships between the internal force and deformation of pre-twisted Euler beam, the generalized strain, the equivalent constitutive equation and the equilibrium equation of pre-twisted Euler beam are developed. Based on the properties of the dual-antisymmetric matrix, the general solution of pre-twisted Euler beam is obtained. By comparison with ANSYS solution by using straight Beam-188 element based on infinite approach strategy, the results show that the developed method is available for pre-twisted Euler beam and also provide an accuracy displacement interpolation function for the subsequent finite element analysis. The effect of pre-twisted angle on the mechanical property has been investigated.
