이 연구에서는 과학사적 관점을 토대로 온도와 열의 개념 유형을 구분하고, 초등 중등학교 과학 교과서에서 열과 온도에 대해 진술하는 개념을 분석하여 학생들이 가질 수 있는 오개념의 원인을 파악하고자 하였다. 분석 결과, 초등학교부터 고등학교까지 과학 및 화학, 물리 교과서에서 제시하는 열과 온도의 개념이 현대적인 관점을 제시하지 못하고, 과학사적으로 변천해온 개념들이 뒤섞여서 제시되고 있다. 이러한 문제점은 학생들이 열과 온도에 대한 정확한 개념을 호기득하는데 방해가 될 수 있을 것이다.

본 연구는 우리나라 초등학교 교과서와 지도서를 '수 세기 이론'의 관점에서 고찰하였다. 먼저 여러 선행연구를 통해 수 세기가 초등학교 수학에서 어떠한 의미가 있는지 검토하였다. 이를 바탕으로 우리나라 교과서와 지도서, 이어서 미국, 싱가포르, 중국 교과서를 조사하였다. 그 결과, 이들 교과서는 우리나라에 비해 수 세기 이론의 관점을 전반적으로 적극적으로 반영하고 있었다. 특히 연산의 중요한 기초로서 수 세기를 명시적으로 활용하고 있는 점이 우리나라와 큰 차이를 보였다. 지도서는 수 세기 이론을 몇 차례 소개하지만 내용이 제한적이고 이론의 전후 맥락이 선명하지 않았다. 이러한 고찰을 바탕으로 수 세기 이론의 초등학교 교과서 반영에 대해 논의하였다.

Background and objective: This study was conducted to find out the status of plant utilization in the current textbooks by analyzing the plants by grade and subject in the national textbooks for all elementary school grades in the 2015 revised curriculum in Korea. Methods: The data collected was analyzed using Microsoft Office Excel to obtain the frequency and ratio of collected plant data and SPSS for Windows 26.0 to determine learning content areas by grade and the R program was used to visualize the learning content areas. Results: A total of 232 species of plants were presented 1,047 times in the national textbooks. Based on an analysis of the plants presented by grade, the species that continued to increase in the lower grades tended to decrease in the fifth and sixth grades, the upper grades of elementary school. As for the number and frequency of plant species by subject, Korean Language had the highest number and frequency of plant species. The types of presentation of plants in textbooks were mainly text, followed by illustrations and photos of plants, which were largely used in first grade textbooks. In addition, as for the area of learning contents in which plants are used, in the lower grades, plants were used in the linguistic domain, and in the upper grades, in the botanical and environmental domains of the natural sciences. Herbaceous plants were presented more than woody plants, and according to an analysis of the plants based on the classification of crops, horticultural crops were presented the most, followed by food crops. Out of horticultural crops, flowering plants were found the most diversity with 63 species, but the plants that appeared most frequently were fruit trees that are commonly encountered in real life. Conclusion: As a result of this study, various plant species were included in elementary school textbooks, but most of them were horticultural crops encountered in real life depending on their use. Nevertheless, plant species with high frequency have continued a similar trend of frequency from the previous curriculums. Therefore, in the next curriculum, plant learning materials should be reflected according to social changes and students' preference for plants.

The purpose of this study was to analysis natural disasters which can be applied environmental education for elementary students. For this study, the elementary society and science textbooks were selected. The results of this study are as follows. the society textbooks contain 2 units of the natural disaster in the 4th and 5th grades. In the science textbooks, 5 units of the natural disaster were showed in 3rd, 5th and 6th grades. The learning quantities were 4 hours in society textbooks and 7 hours in science textbooks. In society textbooks, the contents relating meteorological disasters were dominance. But the science textbooks were showed both meteorological and geological disasters. In aims of learning, while the society textbooks were focused as damages, prevention, counter-plan and restoring plan of the natural disaster, the science textbooks were emphasized damages. the photos in society textbooks, meteorological disasters were superiority in number; especially the flood and heavy rain were 76%. In science textbooks, the photos about earthquake were prominent as 40%. For activating environmental education in elementary school based on these results, it can be suggested that the effects of natural damage as tsunami and global warming should add to elementary textbooks. And the elementary teachers need to understand contents and photos relating environment problem in the elementary textbooks.

Whether textbooks faithfully reflect the curriculum contents is an important educational issue. The previous studies on the textbooks did not analyze the relationship described in the textbooks or the structure. In this regard, this study aims to analyze how the concept of life science area in the elementary school science textbooks developed on the basis of the 2009 revised curriculum is linked. In addition, it seeks to analyze how the concept presented in the learning content achievement standards of the curriculum is connected to other concepts. Towards this end, the conceptual linkage of eight units in the life science domain of elementary school science textbooks based on the 2009 revised curriculum was analyzed. The contents of the life science domain in the science textbooks were analyzed through a semantic network analysis, and the semantic network on the concept linked to the one described in curriculum's learning objectives was also analyzed. The results are as follows: 1) It will be difficult for students to understand the concept due to the complexity of the semantic network resulting from a number of concepts. 2) The curriculum's learning objectives presented in the curriculum are not faithfully reflected in the textbooks. 3) The textbooks are described on the basis of specific curriculum's learning objectives. Based on the findings of this study, the number of concepts described in the elementary school science textbooks needs to be significantly reduced so that the concepts can be meaningfully linked to each other.

This paper investigated the teaching and teaming of contents-related graphing in Korean secondary textbooks and suggested the improved methods of graph instruction through this analysis. reification-the case of function, In Harel, G., Dubinsky(Eds.), The Concept of Function : Aspects of Epistemology and Pedagogy Textbooks are analyzed from the viewpoint of the proportion of graphing contents, their sequencing, the proportion of each domain in graphing activities (interpretation vs. construction, quantitative vs. qualitative aspect, local vs. global aspect) and tasks (prediction, translation, scaling), and the difference in the graphing contents between the sixth and the seventh curriculum. This analysis demonstrates that graphing contents are increasing in textbooks, therefore the high school textbooks appear in almost every content area. The graphing activities concentrate on the construction, the quantitative aspects, and the local aspects, and are gradually focusing on the interpretation and global aspects of high school textbooks. Furthermore, most of graphing tasks favor translation. In contrast, the current seventh curriculum includes a balance of interpretation and construction activities and has more global aspects than the sixth curriculum based textbooks; however, the qualitative approach still rarely appears. For the graphing tasks, translation is still prevalent, but the importances of prediction tasks based on graph have increased in comparison with the sixth curriculum textbooks. Further, the seventh curriculum based textbooks are designed to stimulate more dynamic graphing instruction by introducing new tools such as graphing calculators and computer software. We suggest that the qualitative and global aspects should be emphasized in early graph instruction, a variety of graph activities in realistic contexts should be performed, and educational technology such as graphing calculator and computer can be efficient to implement these ideas.

Investigation on the appendices was carried out to acquire teaching materials about improvement of a appendices and development of teaching-learning activities for science textbooks in Korean middle schools. We analysed the appendices for 30 kinds of science textbooks used in Korean middle schools during $1969{\sim}1994$ years. In the results there were three kinds of pattern for the appendices, such as appendix, non-appendix, and similar appendix without appendix title. The content of appendices were summarized as six categories. such as list of science and scientist history, SI unit-constants and symbols, handling methods of instruments for basic experiments, measuring methods and inquiry activity, safety and precautions, and supplementary data with figures and tables. The appendices of six categories were mostly a content of general and integrated science, and were concentrated in the first grader's textbooks. There were many appendices about the methods for basic experiments such as 'How to Use of Experimental Appliances' in the first grader's science textbooks, but there was no or lack of them in the second and the third grader's science textbooks in the middle school. By the ratio to the pages of appendices which were included according to curriculum changes. the ratio was found to be 4.47% which was the highest in middle school science textbooks at the second curriculum and to be 3.47% which was the highest in high school biology textbooks at the second curriculum. The results of this study indicated that the science textbooks should include as many appendices as possible, because teachers could utilize them in teaching activities and students should be able to be given much help in self-learning.
