The status of facilities, management for the experiment, practices, teaching methods in middle schools have been investigated. The present status and reasonable management of the middle school science education have been grasped from the questionaires. To do this 125 secondary science teachers, 1,745 students and 70 principals of schools in Korea are administered questionaires of Science Education Reserch Institute of Kyungpook National University(1996). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the middle school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of middle school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of middle school science education were proposed in this paper

As a comprehensive study on the development of curriculum for environmental education based on the standpoint of ecology, the environmental issues within the science textbooks used in the elementary, middle and high school were analyzed with the special emphasis to four aspects; 1) the causes and 2) the examples of environmental pollution, 3) the principles of ecology, and 4) the endeavor to overcome environmental crises. The results confirm that the science textbooks were written on the basis of Environmentalism rather than Ecology, and the environmental issues were listed fragmentarily within the subjects related to science, and not systematically assembled between inter-subjects or-sciences. Therefore, the systematic and inter-scientific approaches based on the ecology will be needed for further and better environmental education.

We have analyzed affecting factors of boiling point measurement and proposed to improve these after identifying errors of boiling point experiment in 7th grade science textbooks of 2009 revised curriculum. In the result of analyzing affecting factor of boiling point measurement for nine kinds of science textbooks, we have identified six affecting factors like as types of thermometer, heating instrument, sealing or not of stopper, position of thermometer, shape of container, and volume ratio of material and container. When performing experiment of boiling point measurement, we identified the best results when heating with a hot plate, positioning thermo sensor of MBL near neck branch after filling and sopping 10% volumes of material in round bottom flask. Based on this result, we have compared nine kinds of 7th grade science textbooks and found many errors that must be corrected in most of textbooks. Therefore it should be improved the experiment of science textbooks to enhance the understanding of students and to prevent from misconceptions for boiling point measurement.

This retrospection of elementary science education is very carefully and only my opinions during about 40 years in my life. They are a few articles as follow, 1. My body put into science education about 30 years ago, and started college life at that time. 2. The author participated the SCIS programs from the Unites States. 3. He participated in the development of elementary science textbooks (units on earth science parts and photographs), observation note-books, and teachers guides from third period (1973) to sixth (2000), and also middle school textbooks in 1976. 4. He participated in the setup of science education center in Chenogju National University 1976, and science gift education center 1998. 5. He was the member of earth science Part in observation group to visit south Asia (Japan, Philippines, Malaysia and Thailand on 1-28 August, 1977. 6. He was the president of KOREAN ELEMENTARY SCIENCE EDUCATION SOCIETY in 1997-1998.

The primary purpose of the study was to determine the appropriateness o the inquiry processes and its activities as described in Science 8's which were written according to the 7th National Science Curriculum. It was found that the basic processes were well reflected on the textbooks analyzed for the research. However, only a few integrated processes and the inquiry activities could be read on the same textbooks. Furthermore, a large majority of the inquiry processes and activities were not agreed with what the tasks and titles say. Especially, the none of as many as 216 experiments were not coincided with their titles' intentions. Also suggested in the paper were the implications of the results for inquiry-based science education in the Korean middle schools.

Motivation is a generative power of making learning interesting and sustaining learning for students. Textbooks are important tools in carrying out lessons. And it is meaningful to analyze how textbooks motivate learning. This study is to analyze components of motivation in learning of the 7th grade middle school science textbooks. Keller's ARCS model was used for the analysis. The result of the study is as follows. First, the eight textbooks had various components from A1 to R3. Second, analyzing textbooks by parts of the textbooks, the body had the most motivation strategies and the next was the introduction, lastly the finishing part. Third, the most frequently used strategy on the attention factor is A1. And the most frequently used strategy in the relevance factor is R3.

The purpose of this research was to compare structural organization of North Korean English textbooks pre and post North Korean 2013 curriculum revision. 5 revised textbooks were selected and compared with old textbooks. First, revised textbooks are dramatically changed into colored printed edition. Second, there appears phrases related to Kim Jong Un for the very first time in the preface. Third, while old textbooks emphasized only reading and writing skills, new textbooks integrate 4 skills. Fourth, new textbooks follow united organization system according to the kinds of school; 7 sub skills of Reading, Listening, Speaking, Writing, Grammar, Vocabulary, Pronunciation for general high middle textbooks and 5 sub skills of Listening, Speaking, Reading, Writing, English in Use for the first high middle textbooks. Also, new textbooks integrate English and other subject contents such as science, geography or computer. Finally, the changed structure organization of new textbooks seems to be similar with the ones of English books in the reference which is presented for the first time in North Korean textbooks.

The purpose of this study was to find out the problems on the fractional distillation experiments in the middle school science textbooks based on the 6th curriculum and to suggest an efficient experiment method for the middle school students. The first step was the classification of the experiments in 8 science textbooks according to heating apparatus and liquid mixtures. The second step was doing each experiment 3 times followed by the experimental process in the textbooks. The third step was developing the alternative experiments for solving the problems found in the second step. The heating method used in the alternative experiments were direct heating, oil bath, and heating mantle. The results of the second step showed that the direct heating experiment of branched round flask was more close to the theoretical prediction than the experiment of water bath heating of branched test tube. Also the direct heating experiment of thermally insulated branched round flask was better than the result of the experiment which was not insulated. The results of the third step showed that the experiment using heating mantle regulated heating power by observing the temperature of distillate gave the closest result to the theoretical prediction. From the above results, it is concluded that the experiment using branched test-tube with water bath heating is not adequate for the fractional distillation and an alternative experiment using insulated branched round flask with heating mantle regulated heating power during experiment is recommended.
