It is often assumed by many people that science is male-oriented subject area. It is due to the fact that many examples and models dealt in the science teaming are male, and also there are more male scientists and female. Because the content of many science books are male-centered, it reinforces interest and self-confident for boys, whereas, it discourages the inspiration to develop the identity of scientists as a woman. In the West, in order to solve these issues, the educators have attempted to identify various factors in the science achievement, job description, and others which may contribute in developing gender difference in science learning and attitude towards science. It is also further attempted to develop girl-friendly science learning materials to facilitate education of woman scientists and also encourage their participation in the areas of science and technology. In this study, various strategies for female science education have been explored and suggested by examining science learning programs for female students, analyzing research literatures on the gender difference in science education.

Freudenthal의 수학화 이론에 대한 지금까지의 대부분의 연구는 이론의 탐색에 집중하고 이에 따른 학습 지도 방안과 자료개발에만 역점을 두었던 것이 그 한계점으로 지적되어져 왔다. 이에 본 연구자는 실제 이 이론이 어떻게 학습 현장에 적용될 수 있는지에 대해 첫째, Freudenthal의 수학화에 의한 도형 지도에서 학생이 어떻게 수학화를 이루어 가는지를 조사하였고, 둘째, 학습의 주체자인 학생들의 능동적인 활동을 강조한 수학화 과정에서 교수의 주체자인 교사는 학생들의 수학화가 원만히 이루어지게 하기 위하여 어떤 역할을 수행하게 되는지를 중학교 1학년 학생을 대상으로 사례연구를 실시하여 조사하였다.

This study is on the teaching-learning of parameter concept in secondary school mathematics. In our school mathematics curriculum, parameter concept is explicitly presented at high school mathematics textbook. But student have difficulty in understanding parameter concept because this concept is implicitly used in the textbook from 7-grade mathematics. Moreover, it is true that mathematics teacher give a little attention to student's understanding of parameter con- cept. In this study, we analyzed concept definition of parameter and the extension of parameter on the basis of preceding research, our mathematical curriculum, mathematical dictionaries. After that, we concluded that parameter is explicitly called in t where x= f(t), y= g(t) and parameter is implicitly treated in the learning of relation between quantities in our mathematical curriculum. We pointed to the importance of parameter concept in the successful learning of school algebra. Specially, when the level of algebra is in the learning of relation between quantities, parameter is the key concept for understanding and representing of families of equations or functions. In mathematics class, students have opportunity to reflect that what the role of each variable(parameter, dependent variable, independent variable etc.) is, and where the information which determines it comes from. It is for mathematical communications as well as learning school algebra. Therefore, mathematics teacher's didactical attention is more needed to student have a good concept image of parameter before they learn explicitly its concept definition.

In this study, we conducted classroom activities that are exploring and explaining visualized materials for problem solving of school mathematics with pre-service teachers in 2007~2009. After finishing these classroom activities, pre-service teachers recorded an afternote that includes changes of their thinking about mathematics and mathematics education through these activities in this study. We collected various opinions of pre-service mathematics teachers. From the analysis these data, we searched educational effects of our classroom activities. Through conducting the practice like these classroom activities of our study, pre-service mathematics teachers will have an opportunity of a practical training that supports the teaching of mathematical problem-solving. Moreover their PCK will be enhanced. Also, They will learn a good way to realize the aim of school mathematics curriculum.

Although students can make their questions to clarify their curiosity, there are variety of reasons why a student cannot ask a lecturer. For example, they are ashamed to ask questions. In particular, in case of the class to attend many students, the situation for the difficulty of the question will be caused even greater. Recently, in order to overcome this problem, the Audience Presentation Program (APS) to share students' questions and comments have been introduced, it has widely used. The APS system enables students to ask questions more easily and comfortably. In this paper, we have analyzed the effect of the APS system on the basis of questionnaires in terms of easy-to-use, preference, engagement, etc. According to the results of this paper, we found that all students were satisfied with the APS system.

프로그래밍 언어 교육은 컴퓨터 분야의 필수 과목으로 교육되고 있으나 교수자와 학습자에게 가장 어려운 과목으로 인식되고 있다. 본 연구에서는 명지전문대학에서 시행하고 있는 튜터링 제도를 프로그래밍 언어 수업에 적용하여 학습공동체(피어 튜터링)를 활용한 학습 지원 프로그램을 프로그래밍 언어 교육에 적용한 사례를 제시하고 학습자에 미치는 영향을 조사하였다. 학습 공동체 프로그램의 참여는 자발적으로 이루어졌으며. 활용 결과 학습자들의 성적이 단기간의 프로그램 참여로 많이 향상되지는 않았지만 튜터와 튜티 모두 프로그래밍 과목에 대한 흥미가 유발되고, 수업 참여도가 높아졌으며, 참여하지 않은 그룹과 비교하여 탈락자 감소에는 도움이 되었던 것으로 판단된다.

The purpose of this paper is aimed to derive suggestions for convergence technology for effective management of distance education by analyzing a long-term case. The experiment was designed with notebook, smartphone or tablet based robot controlled by a remote instructor and a learner, who have experience of distance learning including robot assisted learning. The tablet based robot has the display system of feedback to speakers. During five months, three types of experiments were conducted randomly and a participant was interviewed thoroughly. The result, like the previous research, demonstrates that the task performance of the learner in telepresence robot-assisted learning was better than that in the notebook, and smartphone based. However, it is believed to be necessary to adjust the system for eye-contact and voice transmission for the remote instructor. The instructor required an additional sight by supplementing an extra camera and automatic direction control to source of sound.

Even though identical science textbooks are used in elementary science classes, differences exist in teachers' teaching practices. The purpose of this study was to understand the relationships between elementary teachers' beliefs of science learning and their science teaching practices. An Likert-scale survey and interviews were performed on four elementary teachers to obtain information about the beliefs of teachers in science learning. In order to understand their teaching practices and the relationships between teachers' beliefs and their teaching practices, 2 classes per each teacher were recorded and instruction analyses were performed in the aspects of teaching contents, methods, and learning environments. The results showed that teacher A and B, who held traditional beliefs of science learning, taught their classes mainly based on teacher's explanation. While, teacher C and D, who held constructive beliefs of science learning, reorganized the contents of textbooks and applied various teaching methods and strategies in conducting their teaching practices. There were differences in teachers' beliefs of science learning and teaching practices. These differences in beliefs were related with their science teaching practices.

In this study, we examine the cases of instructors who conducted subject management by understanding the learning patterns of convergence major students taking programming courses Therefore, we intend to find implications for the operation of SW curriculum for convergence majors in the future. In the programming class of the convergence major, students of various grades and majors take the course, and a survey was conducted to understand their learning patterns in a non-face-to-face environment. The instructor studied whether it would be possible to induce learners' participation in class even when face-to-face communication was not possible, and tried to operate the class by understanding the learning propensity of the learners. As there are many students who have maintained successful experiences in self-directed learning amid COVID-19, weekly assignments were set so that they could solve their own problems independently, and almost all students submitted assignments. This study is meaningful in that it studied students' learning patterns, task performance, and programming achievement by operating 'Machine Learning' subject to students of the convergence major in a non-face-to-face situation due to COVID-19.
