The main purpose of this research is to search the effect of different types of advance organizers in elementary science classes, to the students in acquiring scientific concepts and its retentions. In order to proceed with the research, We have chosen 93 students of three different classes of fifth graders, studying in M elementary school in U metropolitan city. We have randomly chosen two classes as an experimental group and one class as a comparative group. In the first experimental group (Group1), advance organizer was put in a form of a sentence., and the second experimental group (Group2), advance organizer was put in a form of a picture. For the comparative group, We have not put any advance organizer, and the method of class was proceeded as it was before. The result of this research are as follows. Firstly, the result of 'One-way analysis of variance' on scientific concept grade, right after the experiment on three groups, has shown a meaningful difference that, the shape of advance organizer does affect the acquisition of elementary school students' scientific concept. Secondly, even though Group1, who was given with a sentence as an advance organizer, got higher scientific concept scores after the experiment than that of comparative group, However, there was not a meaningful difference between Group1 and comparative group. Thirdly, Group2, who was given with a picture as an advance organizer, has shown a meaningful difference from comparative group. Judging from the facts above, utilizing an advance organizer of a picture in elementary science class, will be very affective on students' acquiring scientific concept.

The purpose of this research is to find out the problem of plan composition by use the school building. The research was performed through the checking of 13 high schools which were built after 1997 in Busan. Followings are the result of the research. Presently, all the schools are divided classes into different levels and teach students, however, it is only limited to English and Mathematics and being carried on mostly for 1st graders. Moreover, although the plan is composed Department System plan which intended to ues new various learning method, schools have changed their plan into Usual with Variation type which is old educational program and renovated a few classes for certain subjects. Due to above reasons, the new kinds of space for Department System plan is used only as a study room by reform or even not used at all. Therefore, improvement of those problems are significant in schools.

This study investigated the perception and utilization about computer of beginning secondary mathematics teachers by utilization frequency of computer. To increase utilization frequency of computer in school mathematics, our finding shows that beginning secondary mathematics teachers should have an interest in computer utilization and perceive computers as an important tool for mathematics learning. In addition, they are likely to use more frequently computer under the condition that computers have sufficient class materials and supplement their shortcomings that have derived less usage in math classes. Therefore, future studies have to investigate not only how to develope textbooks and run after-school classes but also how to make creative discretional activities by computer, which makes computers more useful for teacher training. In sum, the results of case studies for computer usability should be released to motivate computer utilization and increase mathematical thinking ability.

Purpose: The purpose of this research is to enhance the effect of pictures on sexual education on primary school children which is one of the most crucial topics in health education and to evaluate how utilizing drawings can contribute to the development of school children's appropriate knowledge and attitude toward sexuality. Methods: This research followed the pre-test /post-test experimental and control group design. The selected school children of four classes at sixth grade in the H primary school in Gyeongi-do uijeongbu province had a pre-test about the knowledge and attitude toward sexuality. With the result of homogeneity data, three classes out of the four classes were chosen to be the subject of the post-test and these three groups took the "Sexual Education through Pictures." Results: After analyzing the data, average scores about the knowledge for class participants were higher than the non participants' (p =.000). Average scores about the knowledge of boys and girls who participated in class were higher than the non participants' (boys; p =.00, girls: p =.000). In addition, average scores about the attitude for class participants' were higher than the non participants' (p =.03), but there was not statistically significant among gender. Conclusion: From the results above, "Sexual Education through Pictures" proved to be a systematic and scientific method to develop a positive influence towards the knowledge and attitude of sexuality for primary school children of the sixth graders. These results show that the above teaching materials suggest an effective method to develop appropriate knowledge and attitude towards primary school children's sexual education.

The purpose of this study was to investigate the elementary school teachers' perceptions about the science subject exclusive system. For this study, we developed the questionnaire to investigate teachers' perceptions and 43 elementary school teachers participated in the questionnaire test. And we used participation observation method to investigate characteristics the exclusive elementary science teacher and the elementary school homeroom teacher's science classes. After participation observation, we had interviews with exclusive elementary school science teacher and elementary school homeroom teacher. The results showed that elementary school teachers thought the science subject exclusive system was very necessary. And elementary school teachers thought that the exclusive elementary science teacher had higher professionality about teaching science subject than the homeroom teacher. Then, they expected that the strong points of science subject exclusive system would be some solution to the weak points of homeroom teachers' science classes. We suggested that it must be to enlarge the science subject exclusive system and develope in-service teacher program for the exclusive elementary science teachers.

This study examines the employment conditions and labour experience of elementary after-school care teachers in South Korea. Based on the empirical data collected through in-depth interviews with after-school care teachers in Gwangju Metropolitan City, the study considers multifaceted problems faced by after-school care teachers in their workplace. The after-school care class is part of educational policies initiated and rapidly expanded by the Ministry of Education, resulting in the substantial increase of non-regular school workers. The irregularization of after-school care teachers illustrates that the common problems faced by female non-regular workers, such as social discrimination, exclusion and inequality, are also transplanted into the typical public sector. In the case of Gwangju Metropolitan City, during the past two years there have been evident increases both in under 15-hour short time contract care teachers and outsourcing of care classes. Temporary part-time contract care teachers suffer relentless job insecurity and experience poor working conditions, exclusion and discrimination within the workplace and labour alienation. In order to minimize the organized resistance of care teachers, school authorities implicitly individualize and isolate care teachers through hierarchization, the division of labour and the spatial division of classes between indefinite and temporary contract teachers.
