The purpose of this study was to analyze the characteristics of students' academic achievement of middle school science curriculum achievement standards in the 2009 revised national curriculum and to generate implications for curriculum improvement. Based on the results of the 2015-2018 National Assessment of Educational Achievement (NAEA), we analyzed middle school students' mastery of 84 curriculum achievement standards. In the analysis, we used representative item information by achievement level and correct answer rate and checked the validity of the determination of mastery. According to the results of the analysis, 15 of the 84 achievement standards could not determine the degree of achievement. In science, many achievement standards could be mastered only by above-average group students. By achievement level, there were six achievement standards that advanced achievement-level students did not achieve, 38 achievement standards judged to represent mastery by advanced achievement-level students, 23 achievement standards judged to represent mastery by proficient achievement-level students, and two achievement standards judged to represent mastery by basic achievement-level students. By content area, the number of achievement standards corresponding to advanced and proficient levels was similar in the areas of motion and energy and earth and space domains. In the material and life domains, there were more achievement standards corresponding to advanced levels. Accordingly, it is necessary to reinforce customized teaching and learning activities in relation to achievement standards that were under-achieved.

The purpose of this study is to present the development direction of future reading education by examining the characteristics of reading materials within the high school textbook developed as the 2015 revised curriculum. For this purpose, reading materials of high school textbooks were analyzed in Korean language, mathematics, English, integrated science, and integrated social studies. The analysis criteria of reading materials were subject type, purpose, and student activities. As a result of the study, reading materials on various themes such as humanity, liberty, culture, environment, and district were presented in the integrated society and integrated science textbook of the 2015 revised curriculum. In particular, the Korean language curriculum was composed of a unit called "reading one book in one semester". However, most reading materials have no guidance on reading effective or reading direction, and lack of reading materials and information for extended reading. The reader's reading of the textbook was found to be simply supplementing the learning content of each unit or presenting fragmentary cues for conceptual purposes. This suggests that there is a lack of awareness of students' interest in reading, internalization of reading, and extension of reading. In this paper, we suggest supplementary materials of reading materials for expanding the high school textbooks, and explore the developmental relationship between textbooks and reading education through suggestions on aspects of textbook composition and teaching methods.

Online judge provides compilation, execution, and immediate feedback on the source submitted by the learner, and ensures the accuracy and reliability of the evaluation, but it's difficult to select the language according to the level of the learner because most of them provide only textual language. In this study, a block language for online judge was developed and applied to high school classes, and the difference in self-efficacy between the block language and the textual language group was confirmed. It was found that Block language group have more ability expectation to overcome disgust experience than textual language group and Textual language group have significant decrease in ability expectation to start activity and to continue activity. It implies that Block language has an effect on self-efficacy for afterward programming activities, and methods of teaching, learning and evaluation should be devised in the case of textual language so that student's self-efficacy does not deteriorate at the initial and ongoing stage of activity. The results of this study are meaningful in that it provide various implications of methods for enhancing self-efficacy in high school class of programming.

This study compares the perceptions of elementary gifted child and science teacher in a science class for the gifted. In order to explore the research problem, students and teachers answered a written semi-structured questionnaire and participated in interviews regarding the gifted science class. The data was collected and analyzed. Science teachers recognized the characteristics of a good science class, especially in terms of educational content and teaching methodology. First, they suggested promoting inquiry skills, presenting a challenging task in atypical topic selection, student-centered curriculum, and controlling the pace of learning to recognize individual differences. Second, in terms of the science class skills and attitudes category, teachers recommended raising mutual satisfaction through vigorous interaction within a permissible atmosphere. Finally, science teachers need to strive for continued professional growth. Gifted children, meanwhile, want to investigate a wide range of topics without time constraints. Additionally, they may have to explore challenging topics further. They prefer to act like scientists in that they enjoy group activities, communication and cooperation. In particular, they want to be evaluated by others in a totally embedded assessment. Gifted children also expect teachers to understand the life circumstances and needs of the students. In addition, they asked for teachers to respect individual experiments and to show them how to safely use new equipment or research methods. As a result, gifted children and science teachers have to recognize the differences of opinion concerning a good science class for the gifted. This study can help formulate strategies to establish quality management of materials in gifted science classes.

The 2022 revised science curriculum aims to develop the ability to solve scientific problems arising in daily life and society based on convergent thinking stimulated through participation in research activities using artificial intelligence (AI). Therefore, we developed a science-AI convergence education program that combines the science curriculum with artificial intelligence and employed it in convergence classes for high school students. The aim of the science-AI convergence class was for students to qualitatively understand the movement of a damped pendulum and build an AI model to predict the position of the pendulum using the block coding platform KNIME. Individual in-depth interviews were conducted to understand and interpret the learners' experiences. Based on Giorgi's phenomenological research methodology, we described the learners' learning processes and changes, challenges and limitations of the class. The students collected data and built the AI model. They expected to be able to predict the surrounding phenomena based on their experimental results and perceived the convergence class positively. On the other hand, they still perceived an with the unfamiliarity of platform, difficulty in understanding the principle of AI, and limitations of the teaching method that they had to follow, as well as limitations of the course content. Based on this, we discussed the strengths and limitations of the science-AI convergence class and made suggestions for science-AI convergence education. This study is expected to provide implications for developing science-AI convergence curricula and implementing them in the field.

Probabilistic reasoning and combinational reasoning are essential to build a logical thinking and a process of thinking dealing with everyday life as well as scientific knowledge. This research aims at finding the optimal period to teach reasoning to the students who haven't developed probabilistic reasoning and combinational reasoning. The treatment program was performed for 20 students from each grade who couldn't develop two parts of reasoning. The treatment program using baduk stones and cards was performed repeatedly, focusing on the specific activities. After four weeks of treatment program, the test to check the development of probabilistic reasoning and combinational reasoning was performed again and the changes of reasoning development were identified. After giving treatment program for reasoning development, 15.0%, 25.0% and 40.0% of improvement in the 4th, the 5th, the 6th graders respectively were shown. With regard to the combinational reasoning, the results showed the improvement of 20.0% in the 4th grades, 25.0% in the 5th graders and 63.2% in the 6th graders. As a result of research in the above, students, who were not formed probabilistic reasoning and combinational reasoning, could be known to be enhanced through learning, but to fail to be formed the qualitative change like the cognitive development. It is expected that this research can contribute to the improvement of students' cognitive level and there would be more active researches in different fields to improve the cognitive level of the 6th graders who are in their optimal periods to learn two parts of reasoning.

The purpose of the this study is to analyze consulting demands in vocational education and training (VET) high schools participating the apprenticeship system in Korea. The results of the study are as follows. Firstly, there are 9 sections of consulting that teachers in charge of apprenticeship program in VET high schools demanded. Especially, the demands for the consulting that related with 'student evaluation', 'apprenticeship program development and organization planning of schools' curriculum', 'selection and management of enterprises', 'organization of apprentices classes and student management', 'teaching & learning activities and textbook development' were relatively high. Secondly, there were differences in demands of consulting by VET high schools' current management status. By the type of organization, demands for consulting of both 'training center in main school' of organization and 'training center in common' of organization were higher than 'independent school' of organization generally. By the type of apprenticeship program hours, demands for consulting of both 'above 1400 hours' and '1200 ~ 1400 hours' were higher than 'less than 1200 hours' generally. By the type of OJT operation, demands for consulting of 'a type of OJT that is operated in long term(more than 2 weeks)' were higher than 'a type of OJT that is operated weekly' generally. As a result from above, there are some pre-requisites for the stable operations of VET high schools. 1) The apprenticeship program shall be developed not to interrupt school's regular curriculum. 2) For the smooth management between apprenticeship program and school curriculum, the academic calender has to be established so as the type of OJT operation. 3) The cooperation among the participating schools in part of the organization is unavoidable.
