This study analyzed the frequency and level of scientific practices presented in secondary science textbooks. A total of 1,378 student activities presented in 14 middle school science textbooks and 5 high school integrated science textbooks were analyzed, using the definition and level of scientific practice suggested in the NGSS. Findings show that most student activities focus on three practices. Compared to the textbooks for the previous science curriculum, the practice of 'obtaining, evaluating, and communicating information' was more emphasized, reflecting societal changes due to ICT development. However, the practice of 'asking a question', which can be an important element of student-led science learning, was still rarely found in textbooks, and 'developing and using models', 'using math and computational thinking' and 'arguing based on evidence' were not addressed much. The practices were mostly elementary school level except for the practice of 'constructing explanations'. Such repeated exposures to a few and low level of practices mean that many future citizens would be led to a naïve understanding of science. The findings imply that it is necessary to emphasize various practices tailored to the level of students. In the upcoming revision of the science curriculum, it is necessary to provide the definition of practices that are not currently specified and the expected level of each practice so that the curriculum can provide sufficient guidance for textbook writing. These efforts should be supported by benchmarking of overseas science curriculum and research that explore students' ability and teachers' understanding of scientific practices.

In this study, we explored the meaning of science education in an inclusive education setting tram the view of the epistemological approach, and discussed the principles and theories for constructing an educational program. Also, we explored the possibility of inclusive education in science education by suggesting principles for practice: accommodating science curriculum macroscopically, adapting science curriculum microscopically, considering diversity in science instruction, sharing the differences in science teaching and learning, and restructuring the assessment system in science education. We also reviewed the case on learning basic concepts in optics for the visually impaired according to the principles discussed. In conclusion, we discussed the considerations for the practice of inclusive education in science education and inferred further research problems.

The purpose of this study is to obtain basic data for constructing a modeling practice program integrated with meta-modeling knowledge by analyzing the cognition level for each meta-modeling knowledge components through modeling practice in the context of the chemistry discipline content. A chemistry teacher conducted inquiry-based modeling practice including anomalous phenomena for 16 students in the second year of a science gifted school, and in order to analyze the cognition level for each of the three meta-modeling knowledge components such as model variability, model multiplicity, and modeling process, the inquiry notes recorded by the students and observation note recorded by the researcher were used for analysis. The recognition level was classified from 0 to 3 levels. As a result of the analysis, it was found that the cognition level of the modeling process was the highest and the cognition level of the multiplicity of the model was the lowest. The cause of the low recognitive level of model variability is closely related to students' perception of conceptual models as objective facts. The cause of the low cognitive level of model multiplicity has to do with the belief that there can only be one correct model for a given phenomenon. Students elaborated conceptual models using symbolic models such as chemical symbols, but lacked recognition of the importance of data interpretation affecting the entire modeling process. It is necessary to introduce preliminary activities that can explicitly guide the nature of the model, and guide the importance of data interpretation through specific examples. Training to consider and verify the acceptability of the proposed model from a different point of view than mine should be done through a modeling practice program.

The goal of this study were to look into the elementary school teacher's experience in the self-review of science class and analyze the changes of reflection level revealed in it. This study was a qualitative example research where two elementary school teachers participated and performed self-review via reflective writings regarding their science classes. Both teachers showed changes in aspect and frequency of review to a certain extend by reflective writings based on their class experience and the educational settings they are at. They all revealed a high level of changes on reflection by the feedback from the class reviews. Affirmative changes of cognition on science class and the perception of factors affecting the practice of the class such as understanding students, class observation of the peer teachers et al. contributed to the elevation of reflection level by continuously adjusting and complementing the practical knowledge through the reflection during or after the class.

Recently, ICT has emerged as an indispensable tool for teaching a variety of subjects in education systems. In this paper, we examine the effect of the instructional models for ICT on the practical ability in the application of information with relation to the levels of self-regulated learning strategies. Students were divided into 3 groups, according to the instructional model for ICT which were problem search learning, problem solution learning, and discussion learning. As an experimental tools, we did pretest using self-regulated learning strategies measurement questionnaire and did pretest and posttest using practical ability in the application of information measurement questionnaire. The results show that higher level of self-regulated teaming strategies group has high practical ability in the application of information than lower level group. Other interesting results are also provided.

This study aimed to assess the prevalence of weight control behaviors and their association with food and nutrient intake among Korean adults. Study subjects were 7,340 Koreans aged 20 years and older in the 1998 Korean Health and Nutrient Survey. Cross-sectional data were collected on weight control behavior and diet using structured questionnaire by interview. Analysis of variance following after Duncan's multiple range test was used to test the differences in food and nutrient intake among three different weight control behavior groups(weight reducing attempt, weight gaining attempt, none). Current weight control behaviors were reported by 32% of the study subjects. There were significant differences in weight control behaviors between male and female subjects; weight reducing practices were 7 times greater than weight gaining practices among female subjects while it was only 1.5 times among male subjects. Weight control behaviors were not consistently associated with food and nutrient intake among male and female subjects. Moreover, greater food and nutrient intake were observed among those who trying to reducing weight than those who did not try. Therefore, it Is necessary to educate the Korean adults that balanced food and nutrient intake with sustaind weight control effort is the ideal way to achieve healthy weight.

As one of the essential elements of social work practice, knowledge articulates what the social work profession is doing and ought to do. With an emphasis on building a body of knowledge for the profession, this study analyses the nature of social work knowledge. First, the study examines concepts of social work theories and models, which are built around separate clusters of concepts from a broad base of theoretical orientation. The study reviews epistemological and ideological debates over how to perceive and approach social issues and the role of the social work profession. In organizing a clear conceptual framework for social work practice, different frames of reference and selective and fragmentary knowledge from other disciplines are considered barriers. For the development of a clear identity as a unified profession and the prospects of a value-based profession, more attention needs to be given to specify practical knowledge that is contextual and appropriate to practice settings and more sensitive to social issues.

The aim of this article is to criticize the discourses and practices of the appropriate technology for international development cooperation in Korea which focus narrowly on the technologies and are oriented to the providers of technologies. To present an alternative, we will discuss the appropriate technology by the insights from 'socio-technical system' studies which underline not only technological side but also the social, institutional and user's side, and analyze the interactions between them. This research deals with several cases mainly regarding small scale's renewable energy from Laos, Thailand, Bangladesh, Mongolia and Nepal. We put out some suggestions to improve the discourse and practices of appropriate technology in field of international cooperation by Korea.

In this study, the trend of research and practice of science education for students with special educational needs was discussed in consideration of the aim of science education. Since the 1980s 'science for all' has been suggested as an important goal of science education and it has been pursued in the National Curriculum of Korea with differentiated teaching and learning approach. The meaning of 'science for all' should be expanded to science education for all students including minorities. However, comparing to 'normal' students, there have been relatively little researches and practices for those who need special educational supports as to meet their special talents or as to meet their special mental or physical challenges. Especially, the efforts for handicapped students or students with special educational needs (SEN) have been deficient in comparison to that of talented or gifted students. In this study the authors introduced the history and procedures of a 'Science Fair of Hope' with SEN students as an example of practice of science education for all, and then described the change among pre-service science teachers' attitudes towards disability and inclusive education, so as to discuss the practice and significance of science education for all students including SEN students.
