This study aimed to introduce a case study of a basic engineering design course using the ENACT model for fostering social responsibility of engineers, and to investigate the educational effects of the course. Since the ENACT model was designed to encourage STEM college students to pursue responsible problem solving based on their understanding of socioscientific issues, we assumed that it would be beneficial for engineering students to foster their social responsibility as well as their understanding of science/engineering-related issues. A total of 49 engineering students who enrolled in the course participated in the study. Data included students' course artifacts, reflection papers, and responses to survey questionnaires. Results indicated that the students became more aware of nature of science and technology after the program, and began to solve the problems while considering the views of multiple stakeholders. They highly valued the experience of communicating with others as engaging in the civic activities. They also expressed high satisfaction and feeling of achievement on the course learning. We expect the ENACT model to be an effective teaching guideline that fosters the social responsibility of engineering students and furthermore, engineering ethics.

The purpose of this study is to identify the basic scientific knowledge of in- and pre-service elementary school teachers, specific areas having insufficient knowledge and the reason for the lack of understanding. For the study, we analyzed the survey asking basic scientific knowledge to in-service elementary school teachers within an urban communities and pre-service elementary school teachers enrolling the first, the second and the third year in National University of Education. The results shows that there is the lack of understanding about scientific knowledge such as boiling points, perihelion, substances, and elements, which elementary school teachers should have exactly known. With regard to the age, an effort is required to increase scientific knowledge of the in-service teachers in 50's, compared to those in 20s' and 30s'. In the pre-service teachers, the average in the third year was significantly higher than that in the first and second year. Regarding the major background in high school, both of in- and pre-service teachers who completed the science course showed significantly higher average than those who completed the liberal arts course. In addition, regarding the major in the university, the average of the group with science and engineering major was higher than that of the group with other majors.

This study was attempted to offer the basic data required for composing a systemic education contents for health by analyzing the contents related to health education shown in the guidebook for teachers and the schoolbook for students of all grades in the current 7th education course for elementary school. The objectives and data were totally 162 copies which were 90 copies of national schoolbook for 1~6 grades and 72 copies of guidebook for teachers used in elementary schools in the 7th educational course. The standards of selection for the contents related to health education including in each schoolbook were divided into 11 themes using the health care model suggested by Kim, Hwa Joong(1995) in the guidebook for health curriculum for elementary middle high schools. The results of this study are as follows: Firstly, the total hours of health education suggested in the 7th educational course for elementary school were 274 hours and it was 6.2% of the total class of 4,442 hours. Secondly, the contents about health education were distributed into 9 subjects of The right livelihood, The wise livelihood, The cheerful livelihood, Korean, Morals, Society, Science, Physical education, and Practical course etc. Physical education had the most contents about health education and there was nothing in Mathematics, Music and Arts. Thirdly, contents about health of regional society and environmental health were the most of 53 hours(19.3%), and contents about understanding of health were the least of 4 hours(1.4%). Fourthly, contents included equally in every grades were those about safety and emergency response, health of home and society, health of regional society and environmental health.

The field is a good learning environment that offers many opportunities. Status of conducting field trip in the middle and high school was investigated As a result, there was few teachers who disagree that a course in science should include learning in the field. Yet, on practical side, teachers who used to conduct the field trip over once a year in science class appeared to be about 23% only. Most of schools conducting field trips hadn't well-planned program for instructional activities. Many of teachers appealed that they should not get release time for conducting an extended field experiences, and that they could not obtained good information in relation to the contents, the methods and strategies of field activities. It says that a good field trip needs administrative and financial surport, many informations, and the teacher's exertion.

This study was designed to 10 questions as development of GAP program for ninety high school students(each student of 30 with achievement as high, medium, and low categories), it was analyzed the perception of Earth scientist. High school students have a positive perception about a course in Earth science, but they have lack of knowledge about Earth scientist as a career man, and they can't recognize Earth scientist as a career. A failure of learning of Earth science for Students with low level achievement leads to a negative perception about Earth scientist and disconnection to future career. School education should provide an opportunity to encounter Earth scientist for students and it is badly in need of effort to connect to the job training program.

Special educations for gifted students have not been given enough attention in Japan with a little exception. Indeed, such educations were sometimes despised in Japan by teachers and parents as well as by boards of education, because one of the features of postwar education system in Japan was an excessive egalitarianism. The other is cramming of knowledge in school education, which is necessary for high school graduates to pass entrance examinations for famous universities such as University of Tokyo, or Kyoko University. However, in 1997, some trials of special educations for gifted students started. The Ministry of Education, Sports, Culture, Science and Technology admitted 'skipping a year to enter universities.' In this paper, the following three topics would be discussed. 1. Enrollment of high school students aged 17 into Chiba University. 2. Summer seminars conducted by Japan Mathematics Foundation of Olympiad. 3. Super Science High School Program funded by the Ministry of Education.

The purpose of this study is 1) to survey to identify how high school students think about career guidance and job and 2) to pursue effective career guidance. According to the survey result, first, most students have thought about their career. They chose friends as a counselor for their future. Among respondents, 39.84% of them said they did not consult with teachers. They said academic record is a stumbling block in choosing career. Second, many students responded career guidance should start at 'Junior High school'. 76.56% of respondents said they were lack of career guidance resources. With respect to career, an important subject was shown as the following order: social study, English, Korean, Science and Math. Third, students recognized the face that aptitude and ability should be the utmost important factors in choosing career. They chose mass media as a main source to gain information relative to career, which accounted for 52.34% and 20.31% for teachers. In the case of students who have rather 'poor'home background, teachers were the main sources for career information, whose proportion was relatively high. Forth, parents were the most influential people who helped students choose which high school to go(40.69%). In terms of scope of higher education, 65.63% said they wanted to graduate university. Students who has good academic records and good home environment wanted to pursue Master's or Doctor's degrees. 70.31% of respondents said they attended a high school just because they wanted to have a desired job.

Even though there are extracurricular mathematics classes for gifted students in all levels of schools in Korea, teachers cannot conduct the classes properly because the contents of the textbook are not adequate for the purpose of the classes. So, what they tend to do in the classes is just drilling with many problems which have already shown up at university entrance examinations and various mathematics competitions. The purpose of this paper is to give an example of what the content should be in "Mathematics III" (an elective subject for the science high school students according to the fifth and sixth amendment of national curriculum) and to suggest how to design the extracurricular classes for gifted students. Extracurricular classes of the ordinary secondary school as well as the elective course for the science high school can be suitably designed with choices of topics in the contents of Mathematics III.

Microinterface of W/Omicroemulsion prepared by phosphatidylcholine was used as reaction media of hydrolysis of phosphatidylcholine by phospholipaseA$_2$. Phosphatidylcholine was used as an amphiphile and was acted as a substrate. Organic phase of W/Omicroemulsion in this study was prepared by mixed organic solvents i.e. 2,2,4-trimethylpentane (isooctane) as a main solvent and 1-butanol as a co-solvent. The effect of added 1-butanol was remarkable not only on reaction beginning but also on high reaction rate. The hydrolysis reaction was dramatically initiated when 1-butanol was injected into the running isooctane/PC system. The enhancement by 1-butanol addition into single organic solvent was our original finding compare with previous conventional organic solvent. The reaction rate was elevated by the added amount of 1-butanol. The enhanced reaction rate was about 150-folds. This enhancement was speculated as 1-butanol adsorption on the microinterface. The adsorbed 1-butanol improved the properties of microinterface, especially its mobility was increased by difference of the chain length between phosphatidylcholine and 1-butanol. PhospholipaseA$_2$ molecules were located on the microinterface due to modified mobility of microinterface. Located phospholipaseA$_2$ on the microinterface reacted easily with phosphatidylcholine molecule. As a result high reaction rate was obtained. Microinterfacial properties were successfully improved by adsorbed 1-butanol molecule, and were favorable to appear higher reactivity of phospholipaseA$_2$.

The purpose of this study is to explore high school students' perception of the relationship among science, history, and history of science which is one of the career elective subjects in the 2015 revised science curriculum. This study compares students' perception before and after experiencing history of science course. To do this, data in the format of Venn diagram that students draw to represent their perception on relationship between the history of science, science, and history were collected. The collected data were inductively categorized. As a result of analyzing the Venn Diagram data, there are five different kinds of categories: 'History of science as an intersection of science and history,' 'History of science as an independent domain,' 'History of science as part of history,' 'History of science as part of science,' and 'History of science encompassing both science and history.' And there were 27 different sub-categories within the 5 categories. In addition, before taking the course on history of science, many students tended to regard science history as the intersection of science and history. However, after the course, students' perception changed and differed according to their affiliated academic track. For the humanities, history of science is perceived as part of history, and for the students in science track it is perceived as a part of science. Based on these findings, we suggest that history of science teaching-learning should be conducted that help high school students to experience a new perspective that is different from the curriculum in affiliated academic track.
