The purpose of this study is to investigate the perception about STEAM education of primary teachers who have developed and applied STEAM education to their students through teacher training program. For this study, 101 among 172 attendance are responded to questionnaire of three categories consisting of development and application teaching material for STEAM instruction, and spreading STEAM education. The major findings are as follows: First, when primary teachers develop materials for STEAM education, they consider applicabilities in real classes. Second, they feel the burden of time when they develop STEAM material. Third, they think that their own program has significant educational effectiveness and that students enjoyed the program. Especially, they think that STEAM education program can raise students' interest about learning. Fourth, primary teachers point out the constraints for application of STEAM education program, which are lack of expertise and difficulty acquiring class time. Fifth, primary teachers evaluate the effect of STEAM education program on primary education is positive, and they answer that we need many teaching materials for STEAM education, operating as a regular curriculum, and securing budget. In order to spread STEAM education in field of primary education successfully, administrators have to consider and reflect the voice of teachers.

Researchers have been attending to the potential of curriculum materials as resources for professional development. In order for a curriculum material to fulfil such purpose, curriculum authors should intentionally attend to educativeness of the material. A feature of educative material is that its voice speaks to teachers. In this study, I explore educativeness of Algebra teacher guides by attending to their voice. In particular, I focused on the use of pronouns, modality, and imperatives. Findings indicate that some teacher guides have more educative voice than the others and that the amount each guide talk to teachers were less than sufficient. Implications for future research and practice are discussed.

The objective of this study is to find the most effective educational method on Sex and AIDS/HIV among young people in Korea. The number of people with HIV amounts to 1,224 as of Sep. 2000, and is increasing continuously, especially among young people(National Institute of Health, 2000). In setting up the policy of health education on Sex and AIDS, the criteria should be the effectiveness. By two-stage cluster sampling, 4,713 students were selected from among the 19,093 students from 44 middle and high schools and divided into three groups and taken the education with three different methods( 〈lecture with slides show〉, 〈lecture without any material〉 and 〈lecture through broadcasting system〉) by the same lecturer with the same contents for about 50 minutes. To compare the effects of education by methods, the tests on the AIDS knowledge, AIDS attitude on AIDS and Sexuality attitudes with self-administered questionnaire were implemented three times, that is, ‘before’, ‘right after’ and ‘2 weeks later’ of the education. As to the degrees of change of AIDS knowledge, AIDS attitudes, Sexuality attitudes and subjective evaluation of the education, 〈lecture with slides show〉 was the most effective, 〈lecture without any material〉 was the second and 〈lecture through broadcasting system〉 was the least effective, respectively. In the cost-effectiveness analysis using the results of this study, 〈lecture with slides show〉 turned out to be the most effective, and 〈lecture through broadcasting system〉 was the second and 〈lecture without any material〉 was least effective. From these results, it is suggested that 〈lecture with slides show〉 is more effective health educational methods on Sex and AIDS than 〈lecture without any material〉 or 〈lecture through broadcasting system〉.

디자인교육에서의 표현 재료와 방법은 다양한 양상으로 변하고 이에 의한 미적 효과에 주목하고 있다. 과학 기술이 발달하면서 디자인의 표현 영역도 넓혀지고 과학 기술 발달은 디자인에 새로운 재료와 표현의 방법으로 영향을 미치고 있다. 또한 우리 인간의 오감각에 대한 심리적 요인도 표현의 재료와 구현 방법에 감각적 체험이란 요인으로 현 디자인에서 주목받고 있다. 디자인은 사회적, 역사적, 문화적, 과학-기술적 상황 변화에 따라 급속한 발달을 해 왔다. 디자인의 표현 재료와 방법에 대한 연구를 통하여 창의성 계발과 심미안을 키우는 효과가 기대된다.

In 2004, a department of engineering education was established at Virginia Tech and Purdue university in the United States. Innovation of engineering education for improving the quality of engineering college education has been progressing. Content of subject of engineering exploration was developed newly for engineering college freshmen. And, effect of a sustainable energy design project on academic achievement for engineering freshmen at Virginia Tech in 2006 was researched. The project was performed throughout a 6 weeks period with one by 50 minutes lecture by professor and one 90 minutes workshop by TAs (Teaching Assistants) every week. To analyze the data, statistical package SPSS (ver. 15.0) was used. In responses to an open-ended question about freshmen students' perceptions of their improvement in design skills, the 3 most identified skills were teamwork, design process, knowledge. In, Korea, an innovation relating to engineering curriculum, facility, instructional strategy and so on will be required.

Colleges of technology in Japan are characterized by specialized education starting from the first grades aged fifteen, making it particularly important to provide motivation for specialized subjects. The most difficult thing for teachers in the technical college is giving the motivation to a professional education to the lower grades who don't know the technology and engineering. Teachers tried to use and make a suitable example or an education material for their lecture. The generation gap with students makes it difficult for teachers to use examples of objects that students are actually familiar with in their daily life. To compensate for the generation gap with students, we asserted that education for lower grades should adopt the perspectives of students in higher grades. The relative closeness in age of lower and higher grades helps reduce the generation gap with students, which is advantageous in that teachers can share the perspectives of students.

The second-order scattering (SOS) phenomenon of the interaction of Pd nanoparticles with protein was reported and a simple, sensitive, palladium nanoparticle-based assay for trace amount of protein with SOS technique was developed. The SOS intensities were significantly enhanced due to the interaction of Pd nanoparticles with bovine serum albumin (BSA) or human serum albumin (HSA) at pH 3.5 or 4.0, respectively. The maximum SOS peak appeared at 260/520 nm (λex/λem). The optimal experiment conditions, affecting factors and the influence of some coexisting substances were checked. The SOS intensity increased proportionally with the increase of Pd concentration below 3.0 × 10?5 mol·L?1, while declined gradually above 4.0 × 10?5 mol·L?1. BSA within the range of 0.01-2.6 μg·mL?1 and HSA of 0.01-1.7 μg·mL?1 can be detected with this method and the detection limits were 2.3 and 11.2 ng·mL?1, respectively. The method was successfully applied to the quantitative detection of total protein content in human serum samples with the maximum relative standard deviation (RSD) lower than 2.6% and the recoveries over the range of 99.5-100.5%.
