  • The purpose of this study was to investigate the effects of science instruction using integrative educational model on academic achievement and scientific attitude in gifted classes on elementary science. Integrative educational model (hereafter referred as IEM) was developed by synthesizing the findings from brain research, the new physics, general systems theory, and educational psychology. 77 6th graders of B Metropolitan City's Elementary Gifted Education Center were took part in this study. The experimental group, consisting of 39 students, was applied to the instruction using IEM, while the comparison group, 38 students, was applied to instructor- led instruction. The results of this study were as follows: First, the science instruction using IEM had a positive effect on improving achievement in gifted classes on elementary science. Second, the science instruction using IEM had an influence on inquisitiveness and openness of the lower domains of learners' scientific attitude. Third, the science instruction using IEM had a positive response to learners' interest, comprehensibility about lesson contents, and ability to concentrate on classes.

  • A wavelength-independent optical sensor based on an asymmetric Mach-Zehnder interferometer (AMZI) is proposed. The optical sensor based on an AMZI is very sensitive to wavelength, and wavelength drift will lead to measurement error. The optical sensor is compensated to reduce its dependence on wavelength. The insensitivity of the optical sensor to wavelength mainly depends on the compensation structure, which is composed of an AMZI cascaded with another AMZI and can compensate the wavelength drift. The influence of wavelength drift on the optical sensor can be counteracted by carefully designing the size parameters of the compensation structure. When the wavelength changes from 1549.9 nm to 1550.1 nm, the error after compensation can be lower than 0.066%. Furthermore, the effect of fabrication tolerance on compensation results is analyzed. The proposed compensation method can also be used to compensate the drift of other parameters such as temperature, and can be applied to the compensation of other interference-based optical devices.

  • Korea has the potential to lead the era of the Fourth Industrial Revolution, which succeeded in the information and communication revolution, including the establishment of an e-government. The Go match between humans and computers has led to the realization that humans are starting to live in a new era that they have never experienced before. In 2018, the Federation of Science and Technology Organizations conducted a recognition survey on "what is the most urgent thing?" in the era of the Fourth Industrial Revolution. As a result, it has been shown that the readjustment of the laws of science and technology is most urgent, so it is necessary to analyze the laws of science and technology. According to the research, more than 400 laws are diagnosed, and laws that serve as basic laws cannot lead the Fourth Industrial Revolution. The Framework Act on Science and Technology provides an emphasis on the promotion and management of R&D projects. When analyzing the regulations on 'Development of Science and Technology Innovation System', 'Basic Plan of Science and Technology', and 'Comprehensive Plan for Promotion of Local Science and Technology', there is no suggestion of the Fourth Industrial Revolution. After all, a comprehensive analysis of the current Framework Act on Science and Technology indicates that it is in effect the R&D and Management Act. The "Regulations on the Establishment and Operation of the Fourth Industrial Revolution Committee" poses the problem of defining parliamentary legislation as administrative legislation. 'In addition, if we analyze the Smart City Act, the lack of logical links with the Framework Act on Science and Technology and the Regulations on the Establishment and Operation of the Fourth Industrial Revolution Committee is a major problem. In conclusion, in order to platform the Fourth Industrial Revolution, two improvements can be put forward. First, the Framework Act on Science and Technology shall be abolished to enact the National Research and Development Administration Act, and secondly, the Framework Act on the Fourth Industrial Revolution shall be enacted to absorb the contents of the Regulations on the Establishment and Operation of the Fourth Industrial Revolution Committee.

  • This study sets out to assess the scientific literacy of secondary school students and to describe their differences according to gender, grade, course. This study involved 112 middle school students and 213 high school students. Their scientific literacy was measured by the Scientific Literacy Test designed by Manhart (1997). A 70-item multiple-choice test was used to assess their scientific literacy. The constructs of science factor included 36 items making up physical science, life science, and earth science subtests. The social aspects of science factor consisted of 34 items in nature of scientific inquiry/knowledge, science as a human endeavor, science and technology, and societal perspectives. A two-way analysis of variance (ANOVA) and t-test were conducted using the SPSS program. The scientific literacy score of the middle school students was 45.17. There was no significant difference according to gender but boys tended to perform better than girls on both the constructs of science factor and the social aspects of science factor. The scientific literacy score of the high school students was 51.79. There was no significant difference according to gender. But, boys tended to perform better than girls on the constructs of science factor. Girls tended to perform better than boys on the social aspects of science factor. The students taking a course on natural science got statistically higher scores than the students taking a course on humanities. The high school students got statistically higher scores than the middle school students.

  • The purpose of this study is to investigate the relationships between elementary school teachers' points of view about the organization of the science curriculum and their views on the nature of science (NOS). We surveyed 132 elementary school teachers' view points about these two kinds of views, analyzed the data by their variables, and compared the two viewpoints with their personal details. The elementary school teachers thought the science curriculum should be emphasized through the process more than contents. They thought the contents of the science curriculum should be integrated rather than separated. As teachers' career progressed, they focused on the contents more than the process. On the other hands, because elementary school teachers showed the NOS views as relativism, deductivism, decontextualism, content, and instrumentalism, when we plotted sub-viewpoints of NOS in process-content dimension, we thought it would be similar distributions with point of views on the organization of science curriculum. However, there was no meaningful relation. This showed that teachers' views on the organization of the curriculum and the NOS are totally different. These findings suggest further research is needed to find how factors influence elementary school teachers' views on the organization of the science curriculum and what inclinations can occur in science classes with their different views.
