Elementary science textbooks are the major instructional materials which contain sceientific objectives to be acquired by students. The purpose of this study is to analyze the development system, to evaluate the inquiry activity in current elementary science testbooks, and to make suggestions for the improvement of them. The questionnaires were administered to 116 subjects that participated in development of the 5th elementary science textbooks, and 86 of the subjects responded. Based on the data gathered and analyzed in this study, the major findings are as follows. First, regarding the analysis and evaluation of elementary science textbooks. 1. The instructional objectives in elementary science textbooks are analyzed. The proportions of comprehension objectives is 38%, scientific inquiry process objectives 21%, experimental skills objectives 7%, scientific attitudes and interests objectives 4%. 2. The science concepts in elementary science textbooks of the 3rd grade required the preconcrete operational level(82%) and of the 6rd grade required the postconcrete operational level (73%) by J. Piaget 3. The inquiry activities in elementary science textbooks are emphasizing gathering and organizing results and evaluation, and hypothesizing and designing an experiment Inquiry index of the elementary science textbooks is 76. This is significantly higher than 35${\sim}$50 of America and U.K.. 4. The number of questions per class hour is mostly three, and most of them require the students to explain phenomena in nature or in experiment Second, regarding the development system of elementary science textbooks. 1. The budget for and the period of the development of elementary science textbook should be expanded. 2. For the improvement of elementary science textbooks, more abundant resources and time should be used for the basic study and the field trial of textbooks. 3. The elementary science textbook must include the affective objectives as well as the scientific knowledges and scientific inquiry skills. 4. It is not desirable to assign equal number of pages to the content of physics, chemistry, biology, and earth science. 5. Closer cooperation system is needed among the ministry of education, development research center and the field trial schools.

This study was carried out to develop a physics education program for foreign students of university in Korea to improve their ability to major in the field and to prevent them from becoming dropout. The subjects of the study are five Chinese students attending a natural science and engineering college. Prior to the development of the physics education program, the researchers developed basic physics textbooks for the foreign students and questionaries for diagnosis and summative evaluation, and utilized them to apply a total of seven classes. After the application of the classes, the results of the student's diagnosis and summative evaluation, the teacher's diaries, the observer's diaries, and the transcripts were analyzed by triangulation method. In addition, Nvivo12 was used for the analysis of the teacher's and observer's diaries to help with qualitative analysis. The results of the study are as follows: First, the oder and contents of physics education program for students of the natural science and engineering college were presented in detail, and basic physics textbooks and tools for diagnosis and summative assessment were developed. Second, as a result of the analysis of the diagnosis and summative assessment results of the program, the students' basic physics achievement improved by an average of 40 points due to the application of the developed program. Third, as a result of the application of the program using Nvivo12, meaningful node and actual cases were extracted. There were 10 types of nodes created such as understanding of the students, teaching method, rate of the participation, level differences, language problems, relevance to majors, curriculum and methods of education in the country of origin, cooperative learning, and interest inducement. The researcher provided suggestions on physics education methods for students of science and engineering colleges in Korea based on the related cases.

The purpose of this study was to examine the nature of inquiry activities proposed in high school physics textbooks that were developed based on the 2009 science curriculum in Korea. The inquiry activities were analyzed using the notion of scientific practices introduced in the Science Education Framework (NRC, 2012). The results showed that the inquiry activities in the textbooks emphasized two of eight types of scientific practices including "Analyzing and interpreting data" and "Constructing explanations". In contrast, the activities required students to "ask questions" only once in a total of 291 science inquiry activities. The other types of scientific practices appeared less than 10%. Also found was that the types of scientific practices were not relevant to the way inquiry activities were used for textbook content. Implications for the curriculum and science teacher education were discussed.

The purpose of this study was to investigate how many students understood the analogies for physics concepts used in middle school science textbooks, and which types of analogies they understood better than others. We classified the analogies into the following 4 types: verbal and simple analogy, verbal and enriched analogy, pictorial and simple analogy, and pictorial and enriched analogy. For the study, 46 students were sampled from a middle school in Ulsan city in Korea, and a tool for testing their understanding of analogies were developed. The tool is composed of 8 items, and its face validity about contents and difficulty was verified by 5 experts. It was found that in average only about 50% of the students understood the analogies in the middle school science textbooks averagely, and that the students understood pictorial and simple analogies better than the other types of analogies.

This study was intended to survey and analyze the illustrations of Chinese elementary science textbooks. The analysis criterion was composed of two categories, the kind of illustration and the role of illustration. The kind of illustration was divided into six subcategories categories such as photograph, picture, illustration, cartoon, diagram and recording sheet. The role of illustration was divided into four subcategories such as motive induction, guidance for learning, the supply of learning material, the presentation of learning result. The findings of this study were as follows. Chinese elementary science textbooks have about 3.55 illustrations per page. Compared with Korean ones, Chinese ones have more illustrations. From the analysis of the kinds of the illustrations on grade basis, it was found that the order of percentage of illustrations of Chinese elementary science textbooks is photograph, cartoon et al.. Photograph is prominent in entire grade. And From the analysis of the kinds of the illustrations on domain basis, the same results was founded. From the analysis of the roles of the illustrations on grade basis showed that both supply of learning material and guidance for learning are dominant in entire grade. The role of supply of learning material is a little more major than that of guidance for learning. From the analysis of the roles of the illustrations on domain basis, it was found that in domain of physics and chemistry the role of guidance for learning is major, and in domain of biology and earth science the role of supply of learning material is major.

The purpose of this study is to investigate the learning contents presented in high school science and in pre-service science textbooks of college of education, and to examine educational implications for pre-service science teachers by analysing their connection to each other. High school science is called as 'convergence science.' Seven high school science textbooks and eleven science textbooks related to physics, chemistry, biological science, and earth science for pre-service teachers were selected to analyse learning contents. The relationship between high school science with those of college-level science textbooks for pre-service science teachers was found when the learning contents were compared. Science textbooks for pre-service science teachers have the biggest number of learning contents on the chapter 'Energy and Environment' of high school science. About 86.6% of learning contents of high school science were introduced on textbooks on science, but pre-service teachers should learn the remainder. The part of learning contents presented in high school science textbooks was higher than the college-level for pre-service science teachers. Moreover, the part of learning contents was included in Engineering & Technology. And these required a special teacher education. Accordingly, the results suggested that learning contents for high school science should be optimized and reduced. Also, various educational programs should be developed and educational curriculum for pre-service science teachers should be revised.

Digital therapy has emerged as a novel treatment modality, propelled by advancements in information and communication technology. In the last five years, there has been a substantial surge in research publications addressing digital therapeutics (DTx) interventions, signaling a sustained upward trajectory in this field. The dynamic nature of computer science, marked by continuous innovation and development, underscores the need for agile adaptation to rapid changes. Consequently, computer science education is compelled to offer students insights into the latest trends. This research endeavors to contribute to the evolving landscape by developing textbooks that impart knowledge about DTx, an integration of information technology. The study focuses on the application of these textbooks to elementary and middle school students in South Korea. The instructional materials have been carefully organized to enable students to learn about the principle of Attention Deficit Hyperactivity Disorder (ADHD) DTx at the elementary level and the DTx that can prevent and address the digital drama at the middle school level. Based on the application of the textbook, students who received instruction using the textbook showed statistically significant improvements in all subcategories of creative problem-solving ability, including idea modification, visualization, task focus, analogy, idea generation, and elaboration (p<.01). Additionally, there were statistically significant changes in students' self-efficacy before and after using the textbook, with negative efficacy decreasing, and positive efficacy and social efficacy increasing (p<.001).

The purpose of this study is to develope and analyze a test for the assessment of physics inquiry experiment. To do this, three experiments about 'analysis of motion', 'the relation of force and acceleration', and 'free fall motion' in high school physics textbooks were chosen, and 5 scientific inquiry domains and 16 science process skills have been specified. For each experiments, test sheet of $29{\sim}44$ questions for assessing students' ability about physics inquiry experiment were developed on the basis of the scientific inquiry processes developed earlier. After instruction about 3 experiments mentioned above, a test was administered to the students who took experiment. After the adminstration of a test, the ratio of correct answers, discrimination index, and reliability were analyzed. Using the ratio of correct answers, we can determine item difficulty. Through the D.I(discrimination index), we can find which items can discriminate the students who took experiment well from those who took experiment badly, and we can also find the stability of a test result by the reliability analysis. The test developed in this study were also administered to the students who did not take experiments, and the results were compared with the those of the students who took experiments. With the comparison by chi-square method, we could find which items can discriminate the students who took experiments from those who did not take experiments.

The purpose of this study is to analyze the safety contents presented in high school science textbooks of the 2015 revised national science curriculum. For these, we found safety contents in the inquiries and appendices of 63 science textbooks: integrated science, science inquiry experiment, physics I, II, chemistry I, II, biology I, II, and earth science I, II. We analyzed these safety contents using six safety factors based on the seven standards for safety education. The main results are as follows: First, 81(46.0%) inquiries among 176 curriculum inquiries contain safety contents, and these contents are mainly found in chemistry textbooks, and the least in 'science inquiry experiment' textbooks. Second, safety contents are found the most in 'laboratory safety rule', followed by 'safety symbol' and 'usage of protection equipment'. Third, the safety contents of appendices are mainly in 'laboratory safety rule' and 'accident treatment'. Based on these results of this study, it is concluded that these textbooks have problems; that there is a big difference in describing safety contents in each textbook; that these safety contents are not presented in detail and that the educational effect is reduced. Furthermore, the safety symbol is not standardized. We also discussed ways to improve the safety contents of science textbooks.

In this study, we try to examine its features by using the methods of systematic infographics analysis for visualization materials that are used in Physics I textbooks. Thus, after developing the analytical framework infographics, visualization materials is described in the section "information and communication" and have been analyzed separately as "data visualization" and "Infographics." The results of this study are as follows. First, the analysis framework of infographics can be classified contents of the information, visual representation, and media method. Second, the visualization materials that are displayed in the section "information and communication" of Physics I textbook are of higher quality than most schematized data that are graphically, simple information. Third, the features of visualization materials in textbooks have many relations & functions on 'information content', text & metaphor on 'visual element', illustration & comparison on 'expression type', graphic on 'expression mode', printed matter on 'media method', and horizontal & vertical type on 'the flow of attention'. From the analysis results, in the section "information and communication" of Physics I textbook uses a lot of visualization materials, however it does not provide rich infographics but only simple graphical materials. By utilizing the results of the analysis of textbook and analysis framework of infographics, which has been developed through the this study, let us hope that the opportunity to be able to grasp the importance of infographics in science education be provided.
