This study has been performed in order to achieve three objectives. They are as follows: To analyze, based on the research literatures, the nature of scientific inquiry ability and the characteristics of its constitutive elements. To identify inquiry skills and techniques essential to such areas as physics, chemistry, biology, and earth science. To develop instructional models and materials for enhancing inquiry ability on the part of high school students. It was found in the study that the scientific inquiry was interpreted in terms of different meanings according to the viewpoint of the person who are interested in the nature of science. The scientific inquiry has been viewed as the process of knowledge formation, scientific method, inquiry process or process skills depending on the epistemological, methodological, educational perspectives, respectively. It was also identified that certain kind of skills or techniques would be used for inquiry in only one specific area of the science. The skills and techniques are effectively learned when those are taught with specific knowledge in each area of the science. The model and materials for fostering scientific inquiry skills will be presented on the second part of the report.

The purpose of this study was to examine the effects of the We Start center visiting intervention program on the positive changes in the developmental areas and literacy interests of young children from low-income families. The subjects were 195 young children (109 in the experimental group, M=71.7 months; 86 in the control group, M=73.3 months) living in We Start areas (Ansan, Gwangmyeong, and Suwon cities) of Gyeonggi-do. The We Start center visiting intervention programs were conducted for 30-34 weeks in each city, and pre-tests and post-tests were conducted before and after the intervention programs. The instruments used were the developmental checklist and the literacy interests test The developmental checklist consisted of 7 domains (personality & sociality; language, reading, & writing; scientific thinking; mathematical thinking; arts; social learning; and physical development). The literacy interests test consisted of 2 factors (interest in literacy and interaction during activity). The scores on the developmental checklist showed positive changes in several domains (personality & social development; language, reading, & writing ability; scientific thinking; and social learning), but not in mathematical thinking, arts, and physical development. Second, the results of the literacy interests test showed positive effects on interaction during activity and the total score. In conclusion, the We Start center visiting program for young children from low-income families is an effective early intervention program to end the intergenerational transference of poverty in Korea.

In this paper I attempted to investigate the matters related with the clarification of the close relationship between writing system and pronunciation. On the way of pursuing the research on the subject I found the fact that the same topic has been the main academic target in Korea. There have been some remarks about English alphabets and pronunciation. Nevertheless, the relation between alphabet codes and pronunciation tokens wasn't considered as the main key to master the English pronunciation correctly and completely. As the main target of this paper I argue that it is necessary to comprehend the connection. Then, we can recognize the significant role of alphabetic structure for understanding the gist of pronunciation exercise. This paper is classified into four parts. Each part consists of the material to affirm the fact that writing system should be the inevitable equivalent of sound system, and vice versa. In the first section I show that the development of the way of pronouncing English words is closely related with the endeavors of the scholars. While performing the survey of the studies about the alphabetic structure of the age many scholars found that the spelling construction was recorded without any common denominator. Thus, they not only sought to stage the bedrock for the standard written form of words but also to associate the alphabet letters with phonetic features. Secondly I mention the negative aspect of the 'only spelling based English pronunciation education' for the educational goal of 'Phonics methodology.' In this part I suggest the essentiality of phonemic properties with the phonetic prospect: phonemic awareness. Thirdly I refer to the standardization of the spelling system of English. As the realm of application of the language is extended toward the various professional areas such as commercial, scientific, and cultural spheres, it is quite natural to assume that the usage of the language will be transformed according to the areas in the world. Fourthly I introduce the first English-Korean grammar book with the section of 'the introduction to English pronunciation.' At the chapter the author explained the sound features of English based on the regulation of 'Scientific Alphabet' of U.S.A. In the transcribing system all the symbols were postulated on the basis of the English alphabet form instead of the separate phonetic signs of IPA.

This study was to verify the effect of art-education-oriented integrated human resource education (STEAM) on scientific competence and job competence of middle school students. The theme of the program developed for this study is "food design" using a 3-D printer. The 5 mockup lectures were developed for 237 students in ninth and tenth grades of Y Middle School in Gyeonggi-do Province, and the pre-/post-results were analyzed. As a result of analyzing the competence of STEAM education before and after the program, the job competence of general, science, and food science of students was improved after the program in general. Especially among three sub-areas of scientific competence, the change in component of research shows the most significant change in test statistics. The result of test statistics of food science job competence showed the most significant change among three sub-areas: general, scientific, and food science. This program was developed for on-site to be used for a school lecture, and the program may be reformed or used for different themes.

This study examined pre-service secondary physics teachers' epistemological beliefs about scientific knowledge, science learning, and science teaching in two different science content topics, Lamarckism and the impetus theory. Two sets of open-ended questionnaires, for each of the topics respectively, were developed in the same format. The pre-service teachers completed the questionnaires at one month intervals. The beliefs were analyzed in two dimensions, knowledge justification and knowledge change for each belief area. The findings show that the majority of pre-service teachers held sophisticated epistemological beliefs about scientific knowledge regardless of content topics. On the other hand, more pre-service teachers exhibited sophisticated beliefs about science learning in the context impetus theory than Lamarckism. In the area of science teaching, the majority of pre-service teachers demonstrated a sophisticated view in knowledge justification but a naive view in knowledge change. When consistency across science topics and belief areas were examined, few pre-service teachers held consistent epistemological beliefs across all topics and areas. The difference in the levels of sophistication in belief areas showed that the pre-service teachers did not connect their epistemological beliefs about science knowledge to their ideas about science teaching and learning. This disconnection seems to make the consistency across topics and areas complicated. The difference in epistemological beliefs about science learning and teaching between two science topics need further inquiry. Implications for teacher education are offered.

In order to cultivate the talents needed in the 4th industrial revolution era, it is necessary to select gifted students and train them systematically. The affective characteristics of the gifted are self-concept, personality, sociality, motivation, morality, attitude and interest, and these are important factors that affect science achievement. In particular, computer scientific attitude is an important variable affecting computer science achievement. This study developed a computer scientific attitude test based on TOSRA developed by Fraser to measure the affective characteristics of information-gifted students. The computer scientific attitude test is composed of 7 areas: social implications of computer science, attitude to computer scientific inquiry, adoption of computer scientific attitudes, adoption of computer scientific attitudes, leisure interest in computer science, career interest in computer science, and normality of computer scientists. The relationship between computer scientific attitude and academic achievement of gifted students was analyzed using the developed test. To determine find out whether computer scientific attitude significantly predicts academic achievement, the results of a regression analysis showed that t = 2.543 and p = 0.025, indicating that the average of computer science attitude significantly predicted academic achievement.

In order to find out whether the traditional mass media in our society are sufficiently functioning as a vehicle of providing scientific information to the public outside the school education, public perception of science articles in mass media and scientific terms used in high frequency in science articles have been examined. To investigate the public perception on science articles, a questionnaire was constructed about the usefulness, importance, access frequency, and understanding of science articles. The questionnaires were conducted in areas with high flow populations such as train stations or subway stations. A total of 425 responses were used for analysis. In order to extract high frequency scientific terms used in science articles, two television companies and two newspapers were designated as target media, and their texts on science articles reported over the last 17 years were collected to investigate the frequency of scientific terms used. Based on the frequency, we conducted the self-report comprehension test for the top 100 scientific terms. The results of this study show that the public in our society has relatively high perception of the importance and usefulness of science articles, however, reading and understanding the articles seems to be somewhat difficult. In addition, the scientific terminology used in science articles has a high degree of comprehension for those of higher education, natural sciences majors, and men. In addition, scientific terms with high understanding degree were characterized according to gender, age, educational background, and field of major.

While scientific explanation is a fundamental component of science, teachers often lack familiarity with the formal structure of scientific explanations and the criteria for assessing their quality. Consequently, this study aims to clarify the concept of scientific explanation and proposes a tool for constructing scientific explanations. The primary objective is to explore the tool's impact on enhancing the explanatory skills of pre-service teachers when it comes to the phenomenon of condensation. The research findings indicate that many pre-service teachers initially operated at a description level during the pre-test. However, the implementation of the tool enabled them to advance their explanatory skills beyond the associative level. Notably, the tool was analyzed for its ability to provide pre-service teachers with a conceptual framework for explaining phenomena and guiding logical explanations and micro-level interpretations. This study holds significance in demonstrating that pre-service teachers can comprehend the formalities and criteria of scientific explanations and apply them to enhance their own explanatory abilities. Moving forward, efforts should be made to enhance the scientific explanation level among pre-service teachers across various topics and subject areas. Furthermore, pre-service teachers need classroom experiences that foster the construction of scientific explanations in authentic contexts.

This research is primarily intended to propose a new concept for aggregate control of impervious coverage using remote sensing and GIS. An empirical study for a case study site was conducted to demonstrate how a standard remote sensing and GIS technology can be used to assist in implementing the aggregate control for impervious coverage as intermediary between decision makers and scientists. Guidelines for a replicable methodology are presented to provide a strong theoretical basis for the standardization of factors involved in the aggregate control; the meaningful definition of land mosaic in terms of pervious areas, classification of pervious intensity, change detection for pervious areas. Detailed visual maps (e.g. estimation of impervious surface allowable) can be generated over large areas quickly and easily to increase the scientific and objective decision-making for the aggregate control. It is anticipated that this research output could be used as a valuable reference to confirm the potential of remote sensing and GIS in the aggregate control for impervious coverage.
