Although methods about teaching basic principles and skills of addition and subtraction is long traditional, view points of interpreting those algorithms and ways of introducing those calculating skills are various according to textbooks at each historical stage of elementary mathematics curriculum development in Korea. The 1st and 2nd stage shows didactic transpositions less systemic. In the 3rd and 4th stage, didactic devices, which were influenced by the new math, for help of understanding the principles of addition and subtraction muchly depends on mathematical and logical mechanism rather than psychological and intellectual structure of students who learn those algorithms. Relatively compromising and stable forms appear in the 5th and 6th stages. Didactic transpositions in the 7th stage focus on the formation of mathematical concepts by exploration activities rather than on the presentation of mathematical contents by text. Anyone who wishes to design an elementary mathematics textbooks based upon the constructive view should consider the suggestions derived from such transition.

The purpose of this study was to investigate explanations of high school chemistry II textbooks and the diversity of chemistry major teachers' thinking types related to dilute solution properties for finding the sources of students' difficulties. Eight kinds of textbooks were analyzed, and the teachers' thoughts were searched by a questionnaire developed for inquiring teachers' preference of explanation types. We analyzed teachers' responses from individual interviews after the questionnaire to discern their deeper thoughts. From the results, it was found that the explanations of the textbooks were not clear enough to have scientific conceptions. The figures and explanations of the textbooks do not match either. It was also found that chemistry major teachers' thoughts were not solid when they suffered cognitive confliction by different situation with their thoughts.

As the main mathematical concepts are presented and expressed in various ways through textbooks during the teaching and learning process, it is necessary to look at the representations used in elementary math textbooks to find effective guidance. This study analyzed sentences used in the definition of mathematical terms and unit assessments of current elementary mathematics textbooks according to word depth (Yngve, 1960) from a syntactic perspective. As a result of the analysis, it could be seen that the sentences in textbook were generally concise, the word depth was lower, and the sentence structure and form were different depending on the individual characteristics of each term. Also, the sentences in the lower grade textbooks were more easily constructed, and the sentences of the term definition were more complex than the sentences of the unit assessments. Efforts should be made to help learners learn mathematical concepts, such as clarifying sentences in textbooks, presenting visual materials together, and providing additional explanations to suit the level of individual learners.

This study aims to investigate how secondary mathematics teachers use mathematics curriculum materials such as textbooks and teachers' guide in planning lessons and for their learning. 24 in-service mathematics teachers participated in surveys and two among them were interviewed. The findings from the data analysis suggest that: a) the teachers actively engaged in decision-making processes of the transition from written curriculum to intended curriculum; and b) the teachers showed a tendency of consulting to the ideas suggested in the curriculum materials for selecting objectives and contents for lessons and the what to assess, not ideas for selecting teaching methods and how to assess. Also, various factors such as students' achievement, participation, interest in mathematics, family environment, and college entrance were identified to influence the teachers' use of the curriculum materials.

The purpose of this study is to analyze the influence of digital textbook use for potential risk group of internet addiction and average group. For this, I selected two samples. One was a group to use digital textbook at school, the other was a group not to use that. Then each potential risk group of internet addiction were sort out in two groups by a test of internet addiction. I firstly compared a average user group and a potential risk group of internet addiction in group to use digital textbook. Also, I too did that in group not to use digital textbook. Then I analyzed the relevance of using digital textbook and internet addiction. As a result, I found that using digital textbook have not the relevance with internet addiction. But in this paper, I proposed a way to teach ICT ethical training before students use the digital textbook, because most of potential risk students of internet addiction tend to think they was influenced by digital textbook.

The purpose of this paper is to examine how European textbooks reflect Seoul nowadays. The study focuses on the trend of textbooks in main European countries, such as England, France, Spain, Italy, and Germany. They tend to describe Seoul as one of the mega cities with urban problems, and introduces the city as an economic center which is responsible for interaction with other mega cities. Besides, Seoul is also described as less competitive city compared to others, and its history and cultural resources are not paid attention. Despite everything, it is fortunate that there are very few errors in descriptions of Seoul. In future I expect that descriptions of Seoul in European textbooks are enhanced in not only economic aspects of Seoul but also historic and cultural aspects of Seoul and then European textbooks get more reliable contents to inform Korea.

The purpose of this study is to construct contents of elementary and secondary education which will be included in the information literacy education and to obtain basic information and implications necessary for developing new textbooks. For this study, three types of previously developed textbooks for information literacy education were analyzed, and curriculum content structure, and textbook structure of the draft version of the textbook 'Media and Information Life' developed in 2019-2020 were analyzed. The analysis results are as follows. the information literacy education textbook applied the information problem solving process model and contained the contents of print, and digital media and the media literacy necessary for democratic citizens, but it was necessary to add the types of libraries and media in sequence. Second, library, media, information, and reading literacy were major learning elements that made up the contents of the information literacy curriculum. Third, the "media and information life" textbook needed to present subject competencies, generalized knowledge, content system, and achievement standards in accordance with the system of the 2015 revised curriculum. In addition, social discussion was needed to derive the name of the information literacy curriculum.

New mathematics textbooks for elementary school students are under development according to the 2015 national revised curriculum. Not only contents but also framework of textbooks may be interesting to the mathematics educators and researchers. Considering the high dependency on textbooks in elementary classrooms, the influence of the framework of textbooks in mathematics learning cannot be overlooked. The unit and lesson frameworks of the textbook are important because they are directly related to the quality of mathematic lessons, especially when teachers make a lesson plan based on the unit and lesson frameworks of the textbook. This study is to analyse the unit and lesson frameworks of elementary school mathematics textbooks and to find out elementary school teachers' preference about its analysed key points. For longitudinal analysis, we selected 3rd-grade mathematics textbooks of 5th, 6th, 7th, the 2007, and the 2009 national revised curriculums. For horizontal analysis, we selected 3rd-grade mathematics textbooks of Korea, Japan, United States and Finland. We compared unit and lesson frameworks of various textbooks, and abstracted key elements of the textbook frameworks, and constructed survey questions. Looking at results from survey questions based on analysed key points, we were able to grasp the teachers' preference for unit and lesson frameworks for mathematics textbook. Based on the results of this study, some implications for the development of framework for new mathematics textbooks are suggested.

The contents of 'Nutrition and Diet for Adolescents' in the 12 technology and home economics middle school 1st grade textbooks are analyzed based on the elaboration theory. The elaboration theory is the lecture strategy with 7 essential elements, proposed by Reigeluth. The elaboration strategies shown in 'Nutrition of Adolescents' and 'Diet for Adolescents' are all the same in 12 books, the conceptual elaboration, and the process elaboration, respectively. On the other hand, the elaboration strategies shown in 'Diet and Dietary Habit for Adolescents Nutrition Issues' and 'Proper Eating Habit and Nutrition Issues' are different depend upon the textbooks, all 3 conceptual, theoretical, and process elaborations strategies are shown. The element of pro study is presented by study objective, opening the thinking, and looking back. The summarizer is presented in all 11 but 1 textbooks by various activities and data. On the other hand, the element of analogy has the lowest implementation rate, only 3 among the 12 textbooks implement the analogy. The cognitive-strategy activator and learner control are shown in all 12 textbooks, mostly by data. Implementation of more activities and more analogies might be helpful to the students' participation and understanding the contents of 'Nutrition and Diet for Adolescents'.

The 2009 revised curriculum emphasizes science writing as a way to foster scientific thinking, creative thinking and communicative abilities. This research attempted to find out the aspects of science writing in science textbooks by analyzing seven versions of the 2009 revised science textbooks. The results of the analysis are as follows. First, it was found that the proportion of science writing pages is small and the amount of science writing differs a lot depending on the kind of textbook. Also, science writing is generally located in the wrap-up part of each unit, and the amount and the number of science writing vary substantially from unit to unit depending on the textbook. Second, it was found that 'scientific knowledge-explanation' statements have the largest proportion and 'STS-assertion' statements have the second largest proportion in terms of topics and styles of science writing in science textbooks. Some 'scientific knowledge-explanation' statements are not appropriate to foster scientific ability because they evaluate reading comprehension of the suggested passage as nonliterary writing, not the writing itself as a method to learn science. Third, it was found that there are many predicates that do not indicate a clear purpose of the science writing contained in science textbooks.
