This study aimed to investigate the current state and educational needs of risk education related to science and technology as perceived by secondary science teachers. A survey was conducted with a total of 366 secondary science teachers. The results are as follows. First, There were more teachers who had not provided education on risks arising from science and technology in terms of risk perception, risk assessment, and risk management than those who had not. Global warming was the most common risk taught by teachers, followed by earthquakes, artificial intelligence, and traffic accidents. Second, teachers recognized that they lacked understanding that the achievement standards of the 2022 revised science curriculum include risks that may occur due to science and technology, but they thought they were prepared to teach. Third, teachers recognized that their understanding of risk perception was higher than that of risk management and risk assessment. Fourth, the experience of teachers in training on risk was very limited, with fewer having training in risk assessment and risk management compared to risk perception. The most common training experienced was in laboratory safety. Fifth, teachers recognized that their capabilities for the 10 goals of risk education were not high. Middle school teachers or teachers majoring in integrated science education evaluated their capabilities relatively highly. Sixth, many teachers thought it was important to address risks in school science education. They prioritized 'information use', 'decision-making skills', and 'influence of mass media', in that order, for importance and called for urgent education in 'action skills', 'information use', and 'influence of risk perception'. Seventh, as a result of deriving the priorities of education needs for each of the 10 goals of risk education, 'action skills', 'influence of risk perception', and 'evaluate risk assessment' were ranked 1st, 2nd, and 3rd, respectively.

This study aims to develop and validate a home economics education program focused on the consumer life area to enhance artificial intelligence (AI) literacy. To achieve this objective, a 10-session AI-consumer life integration education program was developed by analyzing literature on AI Literacy, AI curriculum, consumer education, and the home economics curriculum for the middle school consumer life area. The program's validity was assessed by nine teachers using a four-point Likert scale. The average scores for each item and the content validity index (CVI) were calculated. Based on expert feedback, the program was revised and improved accordingly. The expert validity assessment of the lesson plans, teaching materials and learning resources resulted in an average score of 3.78 for all items and an average CVI of 0.96. For the overall program, the expert validity assessment yielded an average score of 3.72 for all items and an average CVI of 0.97. Since the content validity index for all questions was above 0.78, the program demonstrated high validity across achievement standards integration, learning objectives, content and teaching methods, motivation, and volume areas. This confirms its effectiveness as an educational program for enhancing AI literacy. This study is significant in terms of defining and identifying the components of AI literacy, developing an AI-integrated program encompassing the entire consumer life area and confirming the suitability of the home economics curriculum for enhancing digital consumer competencies and promoting sustainable consumption. Additionally, it highlights the potential to integrate AI into the home economics and consumer life area.

The efficiency of the regional fiscal policy implementation is based on the achievement of target criteria in the formation and distribution of own financial resources of local budgets, reducing their deficit and reducing dependence on transfers. It is also relevant to compare the development of financial autonomy of regions in the course of decentralisation of fiscal relations. The study consists in the cluster analysis of the effectiveness of fiscal policy implementation in the context of 24 regions and the capital city of Kyiv (except for temporarily occupied territories) under conditions of fiscal decentralisation. Clustering of the regions of Ukraine by 18 indicators of fiscal policy implementation efficiency was carried out using Ward's minimum variance method and k-means clustering algorithm. As a result, the regions of Ukraine are grouped into 5 homogeneous clusters. For each cluster measures were developed to increase own revenues and minimize dependence on official transfers to increase the level of financial autonomy of the regions. It has been proved that clustering algorithms are an effective tool in assessing the effectiveness of fiscal policy implementation at the regional level and stimulating further expansion of financial decentralisation of regions.

This study investigates science teachers' perceptions of science practices for science assessment. Science practices have information about students' ability to understand scientific knowledge and to perform scientific inquiry. For this study, seven science teachers, who have served for more than five years in secondary schools in Seoul, were chosen. A structured questionnaire consisting of twenty-seven items were used in National Assessment of Educational Achievement. And then, in-depth interviews followed. Co-workers analyzed and discussed the questionnaire and interviews. As results show, science teachers tend to determine science practices based on materials and way to present materials included in questions. Science teachers tend to recognize science practice as different, depending on information and thinking process, which is expected in solving them. In addition, they have a variety of the level of definition and understanding about science practices.

This paper estimates the peer effect of how improving the under-performing students can affect the academic performance of other students, focusing on the ratio of students more than proficient. We take advantage of the regression discontinuity design of the policy assignment rule of School-for-Improvement (SFI), which targeted the under-performing schools as an identification strategy. The estimation results from the 2009-2010 NAEA (National Assessment of Educational Achievement) reveal that the decrease of the ratio of under-performing students tends to increase the ratio of excellent or proficient students at around the policy cutoff. The finding turns out to be robust to various falsification tests.

The purpose of this study was to seek desirable direction of science teaching and to present meaningful ideas for implementing the science curriculum and teaching materials by measuring the degree of the students' understandings on science and comparing it with those of American students. The researcher comprised 790 primary and middle school students for the study and administered them questionnaires developed by Trowbridge, Bybee, and Sund. The questionnaires were analyzed along with three categories such as science method, science theory, and the achievement of scientists. The researcher used t-test and ANOVA in order to compare the difference of their understandings in accordance with grades and gender, and later compared Korean students' understandings with those of similar aged American students administered by the National Assessment of Educational Progress (NAEP) The research loathed to the overall conclusions as follows; Both primary and middle school students' understandings on science revealed positive and appeared no significant difference in gender. And it is thought that science education was being carried out hopefully to enhancing Korean students' scientific literacy, therefore, science teaching like what is implemented to the classrooms currently should be kept on in future. On the other hand, it is necessary to change primary school children's understandings on attitude and value of scientists while to change middle school students' understandings on scientific processes by experiment. Also primary school children need to understand that scientists are willing to change their ideas when new information becomes known.

This paper proposes a computer-based practical automatic scoring system for Korean short answers through student answer analysis and natural language processing techniques. The proposed system reduces the overall scoring time and budget, while improving the ease-of-use to write answer templates from student answers as well as the accuracy and reliability of automatic scoring system. To evaluate the application of the automatic scoring system and compare to the human scoring process, we performed an experiment using the student answers of social science subject in 2014 National Assessment of Educational Achievement.

In this study, we analyzed the PCK components in the materials units of the third and fourth grades of the Korean government-authorized teacher's guides for elementary school, developed in the 2015 revised national curriculum. The results showed that the PCK components were presented in a relatively balanced manner compared to the teacher's guides for middle school. Knowledge of the subject matter accounted for the highest proportion, and knowledge of instructional strategies in science accounted for a higher proportion than knowledge of the science curriculum. The knowledge of assessment in science showed the greatest deviation among publishers, and knowledge of students tended to show the lowest. By subcomponents, experiments and inquiries had a higher proportion than concepts and theories. The ratio of horizontal articulation was lower than that of vertical articulation or lesson objectives, and lesson objectives were presented in various ways, such as in core competencies and achievement standards for science. As questioning was emphasized, teaching strategies and questioning appeared at a similar rate. Motivation and interest, misconceptions were linked to teaching strategies and questioning. In some cases, assessment items and assessment criteria were presented at each level, and various PCK components were linked to these two components. Components with relatively large differences among publishers were supplementary or in-depth concepts, inquiry in textbooks, instruction sequence and method, subject-specific strategies, and assessment items. From the results, the implications for the development of teacher's guides were discussed.

This study analyzed the science assessment items that were conducted by the paper and the computer-based assessment in the TIMSS 2019 pre-test, which is an international academic achievement assessment. We examined whether the test mode influenced the percentage of items answered correctly by each graders. As a result, there was no significant difference in the correct answer rates of science items according to the test media in 4th and 8th graders. Looking at the each graders, the difference in the percentage of correct answers was relatively large in the fourth grader rather than the eighth grader. In terms of items, the difference in the percentage of correct answers was relatively larger for the constructed items than the multiple choice questions. As a result of analyzing the content of science and assessment items on the influence of the test media, the multiple choice items showed little difference between the paper and the computer-based assessment items, but the answer-type items tended to have a lower percentage of correct answers than the paper-based assessment. In addition, by grade, 4th graders showed lower percentages of correct answers in the constructed items than 8th graders. This study provides implications related to the development and introduction of computer-based assessment in Korea, and suggests an educational implications for computer-based assessment to be well established as school evaluation.
