The current elementary mathematics curriculum does not include intensive quantity. However, other subjects also deal with intensive quantity. In order to find a solution to this problem from a pedagogical point of view, the curriculum of mathematics, science, social studies, and elementary textbooks were compared and analyzed, focusing on intensive quantity. As a result of the analysis, the learning contents of intensive quantity were not explicitly presented or the term was not used in the elementary mathematics curriculum. However, intensive quantity was used as a material of activity and word problems in elementary mathematics textbooks. In science and social studies, it was also found that the learning order and content did not match, such as calculating the intensive quantity. For effective learning, it is necessary to consider presenting intensive quantity in elementary mathematics, and to be careful in the composition of learning order and content.

본 논문에서는 프로그래밍 교과에서 학습참여도가 성취도에 끼치는 영향을 규명하였다. 학습참여도는 예습참여도, 수업참여도, 복습참여도로서 학습활동별로 측정되었다. 중다회귀분석 결과, 세 개의 독립변수는 성취도를 설명하는 모형은 유의한 것으로 나타났다. 예습참여도는 성취도에 유의한 영향을 미치지 않았으며, 유의한 영향을 미치는 두 요인 중 상대적 기여도는 복습참여도, 수업참여도 순인 것으로 분석되었다. 이러한 연구결과에 기초하여 프로그래밍 교과의 성취도 향상을 위한 교수학습 전략을 제시하였다.

In this study, the vocabularies in elementary mathematics textbooks for grade 1-2 were analyzed according to 9-degree of semantic system. Also, the types of vocabulary were analyzed using general academic words, mathematics specific concept words, and mathematics general concept words. As a result, percentages of 1-degree and 2-degree vocabulary was the most in both grade 1 and 2 mathematics textbooks. It also shows that some of general academic words were 3-degree vocabulary and some of mathematics specific concept words were either unregistered or 1-degree vocabulary. In particular, general academic words, which are 3-degree vocabulary, may be unfamiliar to 1^st and 2^nd grade students. Therefore, students should be given the opportunity to guess and understand the contextual meaning of general academic words from the given contexts in textbooks. The frequency of use of mathematics general concept words in grade 2 textbook increased significantly compared to grade 1 textbook. Since mathematics general concept words are academic and technical vocabulary they should be taught explicitly. Based on the results of this study, implications for vocabulary instruction in mathematics textbooks were discussed.

This study is aimed at analyzing the achievement criteria of cross-curricular Learning themes that can be linked to curriculums, and developing and applying the career reading programs focusing on the school library. For these purposes, first, a class model was designed in connection with reading education programs through cross-curricular Learning themes of 2015 revised curriculum. Second, the career reading classes in the areas of self-understanding, career exploration and career design have been held through a career reading class model for 137 middle school students in 5 classes for one semester. Third, the data to evaluate the career reading for the analysis of the study was constructed, and the qualitative study was conducted through of anecdotal records, multilateral observation on checklists and the analysis of action research. Lastly but not least, the materials regarding the list of books focusing on the career reading storytelling and the career mentor in a type of interests were presented, and the career reading education activities at the school field were suggested.

This study analyzed the problems of skin beauty textbooks used in high school based on the NCS ability unit, and was to improve them. By the NCS standard, it focuses on the contents which can be learned during the high school course. The main results are as follows. First, the revision of textbooks is to contain NCS competency unit, which is excluded in spite of being taught. Second, Replacement is required for NCS 5 level beyond the high school. Third, the illustrated and photographic materials is revised to improve the understanding by maintaining consistency and visibility. Fourth, the contents on the practical skill need specific explanations and instructional materials. Fifth, to revise terminology and the notation system is needed in skin care. The results of this study can be used as basic data to develop an NCS learning module in the skin care field and high school textbooks.

The purposes of the study were to analyze STEAM instructional materials to find research trends on STEAM instructional program and to develop mathematics-centered STEAM instructional program for middle school second graders. To conduct this study, the researcher collected total 123 research papers and thesis focused on the development of STEAM instructional material and deduced implications for the development of mathematics-centered STEAM instrucational materials from the findings. The researcher found that important components of such as 'context for learning', 'internalization-mmersion', 'new challenge', and 'self-assessment' in STEAM education were not reflected properly in 19 mathematics-centered STEAM instructional programs. Therefore, the researcher put more emphasis on those components in the process of developing mathematics-centered STEAM program.

This study examines the impact of modular robot programming education on middle school informatics curriculum learning motivation. For this purpose, the experiment was conducted with a experimental group of 25 people and a control group of 25 people, and modular robot programming education and learning motivation test were used as research tools. As a result of processing the results of the learning motivation test paper with the independent sample t-test and the paired t-test, the experimental group had 9.36 points higher learning motivation than the control group and 15.44 points higher than the pre-test. In particular, it significantly affected the improvement of all the sub-components of the learning motivation, and among them, it greatly affected the enhancement of attention, relevance and satisfaction. In conclusion, it can be seen that modular robot programming education has a positive effect on improving students' motivation to learn the informatics curriculum.

This study aims to explore how Korean middle-school mathematics textbooks on functions provide students an opportunity-to-learn [OTL]. For this purpose, we investigate 3 textbooks in terms of mathematics content and practice, the level of cognitive demands of mathematical tasks, types of student responses, types of context-based tasks, and connections among the tasks. The findings from the data analysis suggest as follows: a) an opportunity-to-learn to connect procedures to functional concepts and new ideas of functions to the existing one is very limited; b) the textbooks seem to provide students an OTL to understand functions as definitions, rules and conventions and to experience repeatedly procedural executions through worked examples and mathematics tasks; c) students may not experience to explain their own ideas/thinking by using mathematical sentence or justify their own cognitive processes; and d) students can be exposed to get a sense of mathematics as a set of fragmented and isolated facts or procedures, rather than to encourage to expand and deepen their understanding of functions.
