This study is to suggest a method of constructing Informatics textbook considering the cognitive development level of middle school learners. We developed 3 types of learning content models according to the educational objectives and activities of learners and then suggested the methods of constructing textbook. For this, we reviewed the related research results on the development characteristics and cognitive development theories of middle school students. Second, we drew instructional schemes from the pedagogic theories. Then, we suggested 3 models: 'Learning Centered on Concept'. 'Learning Centered on Investigation', and ' learning Centered on Actual Training'. We suggested construction schemes to each model and verified the adequacy using questionnaire to 30 teachers and received the positive responses from most teachers.

This is a literature study about the concept of 'Division into Equal Parts' in middle school geometry. First, we notice that the concept of the division into equal parts in middle school geometry is given in four themes, which are those of line segments, angles, arches and areas. Second, we investigate and analyse the historical backgrounds of these four kinds of divisions into equal parts. Third, the possibility of extension in terms of method and concept was researched. Through the result of this study, we suggest that it is desirable to use effective utility of history in mathematical teaching and learning in middle school.

5 years are passed since the 7th National Curriculum of Education began. The curriculum didn't get successful outcomes, rather brought about several problems. Especially, the computer curriculum didn't effectively deal with fast developing computer technology. In present, the general and overall problems of middle school computer education suggested in many previous researches. After we investigate general computer education problems which computer teachers and students are felt, we must try to reflect the results in computer education policy. In this paper, on the basis of general computer education problems suggested by previous researches, we absolutely analyzed the teacher's and student's question results about correct situation of middle school, and suggested improvement methods of middle school computer education.

This study shows how to use effectively construction and solution of the quadratic equation developed by mathematicians such as Gyung Sun-jing, Hong Jung-ha, Hong Dae-yong, Lee Sang-hyuk, and Nam Byung-gil through mathematics history of Chosun Dynasty. Mathematics history of Chosun Dynasty can be used in order to enhance comprehension and increase interest in an introduction to the quadratic equation. It also can be used to help motivate middle school students to solve the quadratic equation with much interest during the development phase, and develope conceptual thinking and reflective thinking in the practical phase.

The purpose of this study was to investigate the middle science teachers' perceptions on science lessons with experiments. The study conducted a survey for 110 science teachers participating in inservice program. The middle school science teachers taught classes with lectures rather than with experimental activities. They had an experiment one to three times a semester in their lessons. They did an experiment to follow to what the textbook said, or to confirm it, like a cookbook style. The most teachers answered that they had over average ability to teach both lecture and experiment. Through the experiment, they expected students had interests and curiosity on science. Despite the advantages of experiments, there were many constraints to conduct experiments, such as teachers' excessive work, laboratory conditions, education environment, and others. It was demanded on continuous interest and investment in the variation of educational environment so that teachers can experiment more often.

The aims of this research were to analyze and compare verbs in the contents of the 7th, 2007, and 2009 revised national curriculum for elementary and middle school science. After the investigation of 1383 verbs in description of achievement standards and inquiry, we found that 'to know'(15.0 %) in elementary school and 'to understand'(24.2 %) in middle school were the most frequently used ones, totally in these three curriculums. In the 7th national curriculum, frequently used verbs in elementary school were ones related with inquiry such as observation, investigation and so on though 'to understand' had the most common verbs. Secondly, 'to explain' ranked top among verbs in the 2007 revised national curriculum. It showed some possibility of influences of the discussion-oriented situation at that time. Finally, however, in 2009 revised national curriculum, 'to know' and 'to understand' occupied the first and second portion of the verb distribution. In addition, 'to understand' and 'to observe' were used evenly through three curriculums but the portions of 'to know' increased through curriculum revisions. Some implications and discussions were also added with suggestions for further researches.

For the purposes of this research, a corpus of words was created from the English textbooks of the "First Middle School" for the gifted in North Korea, and using the corpus, their linguistic characteristics were analyzed. Although there have been many studies that identified the traits of English textbooks in the North Korea's general middle school, not much focus has been placed on the English textbooks used at North Korea's First Middle School. Initially, the structure of English textbooks of the first, second, fourth, and sixth grades that had been procured from the Information Center on North Korea was reviewed, after which their corpus was created. Then, by using Wordsmith Tools 7.0, linguistic properties and high frequency content words appeared in the English textbook of the first grade were analyzed specifically. Basic statistical data gathered indicated that while the number of vocabulary did not increase as students progress through the grades, the words used tended to diversify incrementally. In the mean time, a distribution of the high frequency content words by grade illustrated that a big difference was found between the content words used in the English texts of each grade, and it was a subject matter of the texts that determined such difference.

This paper has analyzed contents of copyright education in Informatics textbook in middle school curriculum and has proposed ways to enhance copyright education. In this paper, we have analyzed Informatics curriculum, authorized textbook, and teacher's guide book for middle school revised in 2007 and have extracted contents and systems of copyright education in Informatics course. We examined studies on the copyright education and analyzed on the basis of interest, understanding, usage, and practice of copyright. As a result, copyright education has turned out to be focused on 2nd level of information society and information technology. We found that copyright education was necessary both directly and indirectly in various parts and levels in that it is an optional subjects. This paper suggests the possibility of copyright education in Informatics curriculum for middle school and the copyright education is expected to be reinforced.

This study was to analyze the subject objectives of Middle school 7th grade Science textbooks based on the Korean 7th curriculum by using Klopfer’s taxonomic system and find out how much compatible they were with the requiring objectives of the curriculum. Particularly, this study makes educational objectives for textbooks coherent wit the requiring objectives of the curriculum, through the analysing the problems. The results are follows. The Middle school science educational objective of the 7th curriculum sets up almost of the objectives through all of the domains of the Klopfer’s taxonomy system, except the operational function (Category G.0), and emphasizes on emotionable domain (Category $H.0\~I.0$) more. However, comparing with an encouragement objective rate of NSTA, Middle school Science textbooks based on the 7th curriculum were published putting more importance in a cognitive domain, and the intention objective (Category I.0) was not mentioned.
