As the Learning Model (offered major course) of the connected program between high school and college, we conducted a customized education model for second grade high school students with regard to IT. Being based on the latest major trend and practical training within a given period this model has derived the high level of interest and participation from the students. First of all, the first program has focused on the theory and practice. In case of the theory lecture, the new knowledge and practical experiences attracted students' interests. Secondly, the second program mainly consisted of practical training. The basic knowledge through first learning program enabled the students to follow the second course for advanced experiences as well as the variety of new technology. Finally, the survey and evaluation were carried out on the students who finished programs. Most of the students gave answers that both the theory classes and customized practical training were helpful in finding their major and career exploration. The Learning Model of the connected program between high school and college showed that it can be useful not only to extract students' potential ability and good talent but also for university selection and career choices.

Inflammatory bowel disease (IBD) is an immune-mediated chronic inflammatory intestinal condition. With development of various treatment options for IBD, 5-aminosalicylic acid (5-ASA) agents became the drugs of choice due to high efficacy and low risk of complication, specifically effective at inducing and maintaining remission in ulcerative colitis(UC). Pancytopenia caused by 5-ASA agents, especially by mesalazine, has been rarely reported compared with azathioprine, which is commonly used for glucocorticoid-dependent IBD and known to have risk of bone marrow suppression. In the present report, we describe the case of a 57-year-old woman diagnosed with UC, who developed pancytopenia due to adverse effect of mesalazine after recovery from azathioprine-induced pancytopenia. After withdrawal of mesalazine, the laboratory values consistent with myelosuppression continued for 3 months while pancytopenia from azathioprine remained only for 2 weeks. Since pancytopenia can be fatal due to its risk of severe bleeding and infection, close monitoring of clinical presentation is important when starting mesalazine and laboratory data should be evaluated whenever the patients present related symptoms. Furthermore, we suggest that complete blood cell counts should be considered when resuming mesalazine following the development of pancytopenia from any cause, as routinely recommended for azathioprine use.

The purpose of this research is to estimate the chemistry teacher's perceptions of Chemistry I course based on the 7th national curriculum through actual class teaching situations and interviews and teaching guidance of an actual class through a lesson and an interview. For this research, four chemistry teachers who have had an experience teaching the chemistry I course were selected. As the results of the research show, chemistry teachers had the correct understanding of the purpose of the Chemistry I course, but they were teaching the concepts of Chemistry II . They thought the reason for the teaching was the national scholastic aptitude test. But according to analysis, the contents of the previous tests were hardly beyond the limit of Chemistry I course. For this research, the chemistry teachers looked for the purpose of Chemistry I course based on the 7th curriculum only at the superficial views, and the teacher's wrong understanding about the tests disturbed the revelation of the spirit of Chemistry I course of the 7th national curriculum.

The purpose of this study is to analyze the perceptions, demands, operation problems of teacher librarians for the implementation of the high school credit system. 153 teacher librarians working in high schools participated in the online survey, and statistical analysis was conducted Teacher librarians had a high understanding of the high school credit system, and the demand for elective courses management was high. In particular, teacher librarians working at research schools had a higher understanding of the high school credit system and the operating foundation than those in general schools. Lack of awareness of the educational role of students and teachers toward teacher librarians was recognized as the biggest problem in the elective course management and there was no difference according to the background variables of the teacher librarian as gender, region, experience. On the basis of this result, it is suggested and discussed that developing high school credit system training program for teacher librarians, opening of elective courses related to reading, media, and information literacy skills and developing textbook, and instituting mandatory completion courses related to reading, media, and information literacy skills in pre-teacher training course.

In this study, we analyzed the learning elements and achievement standards, and explored the appropriateness and hierarchy of content were analyzed related to the nine types of traditional astronomical instruments presented in the traditional science unit of the History of Science course to improve the problematic situation in which students show low selection rates for the History of Science, one of the elective courses in high school science. Based on the results of this analysis, we suggested ways to utilize each astronomical instrument for teaching and learning in science curriculum with different grade bands. Using the results of this study as a starting point, if a follow-up study that develops specific achievement standards or inquiry activities related to traditional astronomical instruments can be conducted, students' awareness of Korean traditional science culture can be improved, and furthermore it is expected to increase the student's selection rate for the History of Science course.

The purpose of this study investigates high school students' recognition and realities on the integrated science essay and is to suggest desirable direction of integrated science essay of how eduction. To this end, this paper was a questionnaire developed for use, it consists of the status, the writing skills and recognition of integrated science essay. Firstly, all grade students recognize the interest in integrated science essay class, but the need for third grade boys urgently was feeling. Second, STEAM class as a whole than average preference was. Third, integrated science essay was the most relevant, then was mathematics, languages, philosophy ethics, and social. Fourth, integrated science essay class with boys than girls in grade 1, science essay writing, reading science-related essay books, grammar, knowledge of the science and philosophy of science lessons, classes STEAM, read commentary essay reference all on the item, the higher affinity. Currently being implemented in integrated science essay test compared to the first, team teaching approach in schools project under one class teaches students how many teachers should be made. Second, it would require modifications of course content tailored to the preferences of female preference for science higher grade female students to disappear.

This study is focused on the main concepts of gravity and geomagnetics which are introduced in the earth science textbooks of high school in 7th curriculum. This study examines the validity and accuracy of the Earth Science textbooks and shows some effective teaching plans by using the latest materials. This study also illustrates the main concepts of gravity and geomagnetics through presenting some effective and practical teaching-learning methods. The results of the study were as follows: First of all, a number of main concepts of six textbooks of high school were selected; the field of gravity, the direction and dimension of gravity, the measurement of gravity, the main reason of gravity anomaly and geoid, earth terrestrial magnetic field, secular variation of goemagnetics. Secondly, most Earth Science textbooks of high school explains the main concepts of the gravity and geomagnetics in similar ways. Those textbooks, however, don't put an emphasis on the essential contents which has been regarded as important thing in terms of the current educational course of study. The high school textbooks also use the material which is too old-fashioned and has some problems of accuracy and validity. Especially, many main concepts of the textbooks and scientific data(such as the direction of gravity, the measurement of gravity, the main reason of gravity anomaly, the use of geoid, secular variation) are different with those of South Korea, In addition, some materials(graphs and diagrams) are very old ones and they don't have authentic information.Finally, Among the various main concepts, some important ideas (the direction of the gravity and the method of measuring gravity, the measurement and use of gravity anomaly, the definition of geoid and secular variation of geomagnetics) should be corrected by showing the latest and authentic materials.

The purpose of this study was to ascertain high school student ideas on the motion of the Earth and moon by cognitive level. For this study, five students determined to be of high, middle and low cognitive level selected from 73 10th-grade students at a high school located in Suwon, Gyeonggido. The results of this study were as follows: first, students at the high cognitive level had comparatively more logical and scientific conception on the revolution and rotation of the Earth and moon. second, students at the middle cognitive level, generally had a passive learning attitude to unconditionally memorize learned contents, so they were apt to forget learned contents, also their recognized conception was not enlarged. In addition, they had native theories, intuitive ideas and misconceptions as well as made logical errors in the course of explanation for the motion of the Earth and moon. In the course of explanation for the phases of the moon and the cause of change of season, because of their scientific conception, the students made more and more errors in conception. finally students at the low cognitive level were not willing to think logically and positively and were very passive in the attitude to recognize conception. In addition, they have learned helplessness on the grounds that they have low scholastic achievement specially in science.

Recently, the tendency for young people losing interest in science has accelerated. This tendency is remarkable for not only Japan but also some countries of Asia. It is thought that this tendency was brought from the decrease of the chance to watch the actual manufacturing activities, and the decrease of the real experience which children makes something in their childhood. In order to bring up the capable engineers on such a social background, making a product practice which promotes the understanding of the application of theory for manufacturing products is important in addition to study by the text book. In this study, some practical work materials for the lower grades in the college were developed. Integration of the developed materials and the course of study becomes an effective teaching method of the of subjects on a special field. Arranging this practical work on the learning process makes a high effect of the integrated practical work on the curriculum.

The purpose of this study is to identify students' alternative frameworks about tide concept, to investigate some characters of them and students' understanding types with increasing grade in secondary school earth science course. The objective questionnaire method was used, and the subjects of this study are 528 students selected randomly in secondary school. The results are as follow. 1) Thirteen alternative frameworks about tide concept, related to the phase change of the moon and the motion of the earth are identified. 2) The alternative frameworks needed mechanical and causal reasoning have the trend reinforced or sophisticated with increasing the grade. And alternative frameworks needed phenomenal and mechanical, phenomenal and causal reasoning are changed little but ones needed phenomenal, variative and basic reasoning change scientifically. The rates of the alternative frameworks needed definitional, empirical, phenomenal reasoning decrease at the learning grade of that concept but increase after that grade. 3) Middle school students have the definitional, phenomenal, empirical and qualitative understanding types but high school students have the causal, analytic, quantitative and mechanical ones on tide concept.
