In order to improve the quality of textbooks, this study analyzed seven informatics textbooks published based on the 2015 revised curriculum. Content analysis was used to analyze the organization system of these textbooks. Learning objectives of the textbooks were also analyzed according to Anderson's taxonomy of educational objectives. Furthermore, a textbook satisfaction survey, in which textbook selection criteria were applied, was given out to preliminary teachers. The results showed that the textbooks were similarly organized, centered on practice, activities, differentiated learning, and small group learning. However, the number of pages varies considerably for each chapter. After analyzing learning objectives of the textbooks, it was found that in terms of cognitive processes, 'understanding' (53%) was the highest item and 'analyzing' (16%) the second highest; in terms of type of knowledge, 'conceptual' (42%) and 'procedural' (31%) accounted for the two highest categories; in terms of cognitive domains, there has been a significant increase in 'analyzing' and 'creating' facets for learning objectives of these new versions of textbooks as compared to those of previously existed textbooks. In the satisfaction survey on a 5-point Likert scale, 'the accuracy and fairness of the content' had the highest points at 4.21 among four scale items. In this study, the improvement of the textbook is proposed based on the findings from this analysis.

The purpose of this study is to examine the issues of digital textbook policy in Korea, using the four dimensional model of Cooper, Fusarelli, & Randall(2004). Building upon systematic review of the policy documents, journals, and articles, I found some issues and implications for the betterment of the policy: From normative dimension, it is important to overcome widespread view of textbook based on positivist epistemology. From structural dimension, we need to move to curriculum-based textbook system and stabilize the organization in authority within the Ministry of Education. From constituentive dimension, much more consideration and support within the authority are to be provided to teachers and students. Lastly, it is critical to develop and disseminate an effective instructional model and build capacity of teachers' ICT from technical dimension. Building upon the results, clarification of policy objectives, establishment of priorities for school grades and subjects in the mid- to long-term perspective, and the establishment of communicative venue for the gathering of opinions of teachers and students who are key participants and activation of operations.

The purpose of this study is to improve the experiment of dihydrogen production which was newly added to the 7th curriculum of the elementary science education. For this study, the teachers who had taught 6th grade students were asked about the difficulties they ever had in the dihydrogen production experiment by questionnaire. And the contents of the science textbook and teachers' guide book were analyzed. According to this investigation, the following controversial points were found. First, they didn't have exact explanations about the concentration of hydrochloric acid and the quantity of hydrochloric acid and magnesium in the science textbook and teachers' guide book. Second, the experiment which can show well the nature of dihydrogen was not included because of the safety problem. So this paper presents the ideal condition for the production of dihydrogen and an experimental method to show the nature of dihydrogen. The most ideal condition of dihydrogen production includes 40 mL of 2 molarity hydrochloric acid and 1 g of magnesium. It took 5' 42＆apos; on average to gather two bottles (250 mL) of dihydrogen. In this condition it was possible to reduce the risk of accidents and to economize the materials. This paper proposes the experiment of dihydrogen explosion with a test tube and a film box which is not included in the 7th scince textbook. If teachers show the experiment of dihydrogen explosion with a test tube or film box to students at a class, it will be more interesting for students. And they will be able to help students to understand that dihydrogen can be gathered.

This study is to review the content organization and developmental ways of the unit on the mixed calculations and explore the alternatives on the basis of students' responsive examples and error patterns with relation to the mixed calculations, mnemonics of PEMDAS and historical context with relation to the order of operations. Then I analyzed the textbook and manual for teachers of the unit of mixed calculations of fourth grade and improvement about teaching the mixed calculations. First, I pointed out illogical connection between practical problem and rules of order of operations. Second, I suggested constructing a textbook by considering conventional character of order of operations. Third, I pointed out the importance of structural understanding of an expression of mixed calculations and various strategies with relation to teaching and learning. This study is suggestive for textbook development of the mixed calculations.

Mathematics is the subject that requires high mental function such as the ability of logically thinking and investigating. Because of the reason there exists much greater difference in students' individual scholastic abilities in mathematics class than in other classes. Recently many schools organize students into two or three level-based mathematics classes according to each student's level to solve the problem. But in spite of its many merits the new system of class organization has some problems. The problem which is pointed out as the most serious thing frequently is that many teachers still use the same textbook and the same teaching method for all students, not considering student's level. Obviously it causes the reduction of students' interest and motivation. In this point of view, I tried to solve such a problem by development and application of level learning materials reconstructed text book according to students' abilities and levels through this research. As the result of the research to examine the changes of students' emotional factors such as the recognition, interest, and attitude which influence on improving self-educability in learning mathematics has occurred, the following conclusion comes out. 1. Through the mathematics class utilizing level learning materials reconstructed textbook, students come to recognize that level learning materials are more effective than uniformed contents of the same textbook and get more active learning attitude. 2 The application of level learning materials in a level-based class has contributed to increasing students' interest in mathematics. Furthermore it was also effective in the positive changes of students' emotional factors such as the recognition, interest, and attitude which influence on improving self-educability in learning mathematics.

Due to frequent international exchanges, there has been much emphasis on communication proficiency in foreign language education. However, when we look back upon teaching English in Korea over past years, we find that English teaching has been dominated mainly by Grammar-Translation Method, which makes teachers and students pay little attention to listening skill that is regarded as the basis of communication proficiency. Recently many English teachers have shown their interest in listening skill, so they come to use the textbook record tapes to improve listening skill. But listening training by textbook record tapes seems to make students feel bored. So the purpose of this study is to suggest an effective way of improving listening skill by means of Pop Songs that the students are indulged in. The processes of this study consist of three stages : 1) listening to songs, 2) explanation about structures and vocabularies in songs, 3) filling in blanks while listening. The subjects in this study are freshmen 88 students in girls' High School They are grouped into two : one is experimental group and the other control group. Among the subjects, the former have been taught by the lesson plan using pop songs, while the latter by the lesson plan using textbook record tapes. The experiment lasts about 9 months (from March to November, l994) The data for analyzing the study results have been collected from two kinds of tests : one is listening test and the other comprehensive test. The hypothesises of this study areas follows : 1) Depending on hearing materials (experimental material vs traditional material), there will be a difference in scores of listening skills between EG (experimental group) and CG (control group), 2) Depending on the interest on pop songs, there will be a difference in scores of hearing skills in CG, 3) Depending on hearing material. there will be a difference in scores of overall English skills between EG and CG, 4) Improvement in listening skill will give influence on the overall English scores. The findings of this study indicate that pop songs are effective to improve students' listening skill, that students' interest in the hearing material is important, and that listening skill is closely related to other skills, especially reading skill. It can be concluded that English teachers should make efforts to find the suitable listening materials which will help students to improve their listening proficiency effectively.

The fraction concept consists of various meanings and is one of the abstract and difficult in elementary school mathematics. This study intends to find out the implication for introducing the fraction concept by comparing mathematics textbooks of Korea and Singapore. Both countries' students peformed well in recent TIMMSs. Some implications are as follows; The term 'equal' is not defined and the results of various 'equal partitioning' activities can not easily examined in Korea's mathematics textbook. And contexts of introducing fractions as a quotient and a ratio are unnatural in Korea's mathematics textbook in comparison with Singapore's mathematics textbook. So these ideas should be reconsidered in order to seek the direction for improvement of it. And Korea's textbooks need the emphasis on the fraction as a measure and on constructing fraction concept by unit fraction.

In recent elementary school mathematics a word 'stipulation' newly appears. The word is used instead of definition. However, there seems to be some differences between definition and stipulation. So, in this paper we investigate those differences through the concept 'function of definition'. In school mathematics textbooks there are definitions which carry out special functions In mathematical contexts or situations. We can say that we understand those definitions, only if we also understand the functions of definitions in those contexts or situations. Functions of definition are classified as, stipulation-function, discrimination-function, analysis-function, demonstration-function, improvement-function. With these analyses we made a frame for investigating the characteristics of the definitions in recent elementary school mathematics textbooks. As a result of analysing functions of definition we found that generally speaking, stipulation-function is excessively emphasized and the other functions of definition are not explained adequately in school mathematics textbooks. So it is required that the textbook authors should be careful not to miss an opportunity for the functional understanding and the mathematics teachers should be aware of the functions of definitions. Finally, we comment that textbook author, teacher, and researcher should be careful in using the word 'stipulation' instead of definition, because, although there are various functions of definitions, students might ream only stipulation-function.
