Even and odd numbers are taught in elementary school mathematics, but the introductory activities, definitions, and properties of sum on even and odd numbers vary depending on which grade they are presented. The purpose of this study was to compare and analyze the activities related to even and odd numbers presented in Korean mathematics textbooks developed under the different curriculum revisions, and to further analyze the related activities in foreign textbooks to draw implications for the teaching of even and odd numbers. In Korean textbooks, from the time of the fourth mathematics curriculum until the 2007 revision, even and odd numbers were covered in the multiples and divisors unit of the fifth grade textbook, while since the 2009 revision, the first grade textbook has covered the topic along with teaching numbers up to 50 or 100. In addition, the definitions of even and odd numbers varied depending on the grade level and the nature of the unit being taught, and activities addressing the properties of sum were only presented in the mathematics textbook under the third curriculum along with a few mathematics workbooks. In foreign textbooks, even and odd numbers were introduced in Grades 1, 2, or 5, and their related activities varied accordingly. Based on these findings, this study discusses the implications for the teaching of even and odd numbers.

Learning objectives is used to be a good guidance of a class evaluation and activity design for an effective teaching and learning activities in class. Anderson's taxonomy of Educational Objectives that was a revision of Bloom's taxonomy has presented in research field of other subject matters and used as a better guideline for analyzing learning objectives in textbook and achievement levels in test recently. This study has behaved some questionnaires for that Anderson's taxonomy is suitable for a guideline of stating learning objective in Informatics subject matter, and analyzed the learning objectives in 6 Informatics textbooks by Anderson's taxonomy. It has proposed that Anderson's taxonomy is satisfactory for expressing learning objective of Informatics subject matter in class and some dimensions, such as conceptual and procedural knowledge, understand, and apply, are much more used in learning objectives in 6 Informatics textbooks. This results will be a good case study in research about taxonomy of educational objectives and development of Informatics textbooks.

This study was conducted to provide standards for the development of contents and systems for digital textbooks by examining the learners' satisfaction from digital textbooks, which are now being distributed to schools, in terms of ubiquitous learning, and by verifying the moderation effect of learners' computer self efficacy and digital textbook usage. SPSS win 13.0 was used for technical statistics, Cronbach's $\alpha$ coefficient calculation and correlation analysis for empirical analysis, and the MMR (moderated multiple regression) analysis was conducted for the hypothesis test. The following principal results were obtained from the hypothesis tests. First, the ubiquitous learning features had direct effects on the learning satisfaction from the digital textbooks. Second, when the ubiquitous learning features had positive effects on the learning satisfaction from digital textbooks, both the computer self efficacy and digital textbook usage reacted with the ubiquitous learning feature and showed moderation effects. These results were statistically significant.

The purpose of this study was to analyze the democratic civic competencies of the activity tasks in 'the Family Life' part in Middle School Technology Home Economics textbooks according to the 2015 revised national curriculum. In order to achieve the purpose of this study, the activity tasks of six types of middle school Home Economics textbooks (for a total 12 of volumes) were analyzed. As a result, the use of the citizenship competency group was the most often recorded out of the three democratic civic competency groups and the subset of trust and value competencies also were frequently observed. Additionally, democratic civic competency was the seen most within the 'human development and family' area by the national curriculum, and showed the highest frequency in big idea, 'the relationship'. Activity tasks in the 'KH' textbooks were dealing with democratic civic competency the most. Based on the relationship between Home Economics education and democratic civic competencies, it is necessary to study the practice of classroom instruction so that students can develop democratic civic competence in 'the Family Life' by means of a Home Economics curriculum.

As the informal graph was introduced newly in the area of function in middle school mathematics curriculum revised in 2015, ten publishing company became to have a concern on how to represent the graph content uniquely and newly. At this time, it may be meaningful and useful to compare and analyze the content of the graph unit shown on each textbook published by publishing companies. To accomplish this, on fundamentally the basis of diverse prior researches this study tried to select the elements of expression and interpretation of the graph and establish an analytic frameworks of expression and interpretation of the graph respectively. This study executed the frequency analysis and cross analysis by textbook system, textbook, and the number of the graph drawn on a coordinate plane on the representation and interpretation of the graph. As a result, the textbook contains more items on interpretation than the representation of the graph, and students showed a learning effect on the graph unit but showed a neutral response to the impact of learning. This basic and essential paper shed light on developing the practical and more creative textbook which has diversity and characteristic respectively, while adjusting the scope of the elements of the graph's representations and interpretations and providing proper level and quality content.

This study examines how East Asia is represented in US World Geography textbooks and what kind of cultural and political epistemological frameworks are embedded in those representation focused on China and Japan. For this, four World Geography textbooks that widely used in public middle school throughout the State of Connecticut are selected as the major units of analysis and analyzed using content analysis. The results are as follows. First, The textbooks have the cultural epistemological framework that East Asia are portrayed not only as homegenous and static world but also as exotic world whose mode of life is quite different from that the West. Second, China are represented as having more traditional and negative images, whereas Japan are portrayed as receiving more modern and positive images in the textbooks. This difference is caused by the relationship between the U.S. and them and imply that the epistemological framework on East Asia of American can change according to the relationship between the U.S. and East Asia. Third, the textbooks seem to be dominated by colonialism epistemological framework that emphasize hierarchical order between the U.S. and East Asia and omit East Asian countries' contribution to global cultures and economies as political epistemological framework. These findings suggest the need to investigate the epistemological frameworks underlying World Geography textbooks used Korean classroom about neighbor Asia or non-Western societies.

An analysis was done on the “inquiry sections” of Earth Science chapters of 10th grade science textbooks. The Inquiry sections were classified into different types and the frequencies of basic process skills, integrated process skills, and inquiry activities were measured in section to find out whether they sufficiently satisfy the requirements based on the 7th National Curriculum. The number of selected science textbooks that have been used in high school for this study were eleven. The number of inquiry tasks were on an average of 24.0. The types of inquiry sections and the elements of basic and integrated process skills were different in every textbooks. The number of inquiry activities were also different and analyzed more than those presented. They were not integrated activities but presented as scientific process skills. The basic process skills and integrated process skills presented in textbooks were $16\%\;and\;77.2\%$, respectively. However, the distribution of two kinds of process skills were analyzed to be $45.6\%\;and\;55.4\%$, respectively. In the process skills, the frequencies of inferring $(49.5\%)$ and data interpretation (68.7%) were the highest; however, the other process skills including recognizing problem, formulating hypothesis and generalization were not even presented in any of the text books. Due to the lack of the definitions of Science process skills and inquiry activities in the 7th National Curriculum, each text book defined these terms differently. It suggests that the meaning of inquiry, science process skills, and inquiry activities should be operationally defined in the national curriculum and the criteria for construction of inquiry activities are required.

Although mixed calculation of natural numbers is important in that it completes arithmetic calculation of natural numbers in elementary school, few studies have been conducted regarding its instruction methods. Given this, this study analyzed Korean mathematics textbooks (from the fifth textbooks to the 2009 revised textbooks) along with Japanese and Singaporean textbooks in terms of the parentheses and the order of operations regarding mixed calculation of natural numbers. The results of this study showed that there were differences in introducing the parentheses and representing them in an explicit way per textbooks. In the Korean textbooks, the order of operations was presented mostly with the real-life contexts but it was not always in a diagrammatic representation. In contrast, in the Singaporean textbooks, the order of operations was presented without the real-life contexts and the use of calculators was emphasized. In the Japanese textbooks, the order of operations was presented with the real-life contexts and a hierarchy of operations was emphasized. Based on these results, this study suggested several implications of textbook development and instructional methods regarding mixed calculations of natural numbers.

This study was performed the analysis of seven kinds of the hight school chemistry II textbooks based on the 6th curriculum. Particularly, inquiry activity part was analyzed by the three dimension framework which consists of inquiry content dimension, inquiry process dimension and inquiry context dimension. In the analysis of the inquiry content dimension of inquiry activities, the total number of themes in seven kinds of textbook was 212. And the number of inquiry activities in seven kinds of textbook was diverse: A textbook had 28, B textbook 25, C textbook 31, D textbook 35, E textbook 31, F textbook 29 and G textbook 33. As for the avaerage number of inquiry activities of each chapter, chapter I "Material Science" is 3.00(9.91${\%}$), chapter II "Atomic Structure and Periodic Table" 4.57(15.1${\%}$), chapter III "Chemical Bonding and Compound" 6.86(22.6${\%}$), chapter IV "State of Matter and Solution" 7.00(23.1${\%}$), chapter V "Chemical Reaction" 8.86(29.2${\%}$). For the analysis of inquiry process dimension, it follows in the order of 'observation and measuring (66.7${\%}$)', 'Interpreting data and formulating generalizations (26.5${\%}$)', 'seeing a problem and seeking ways to solve it (4.1%)', and 'building, testing and revising the theoretical model (2.7${\%}$)'. As for the analysis of the inquiry context dimension, the scientific context occupied 90.5${\%}$, the individual context 4.3${\%}$, the social context 0.9${\%}$, and the technical context 4.3${\%}$. It shows that the proportion of STS(Science-Technology-Society) related contents in inquiry activities was only 9.5${\%}$.

This study examined how practical reasoning processes were reflected in the revised consumer education of technology & home economics textbooks in secondary schools. Twenty-four textbooks from secondary schools for 7th to 10th grades were analyzed. Areas of textbooks analyzed were introduction, body content, learning activity, and evaluation. Analysis criteria were extracted from the previous literature regarding contents and questions dealing with practical reasoning processes and revised by a researcher of this paper. The results and conclusions of this study are as follows. The results of the analysis of the practical reasoning processes showed that, across all grades, "contexts" was the most common element, and "alternatives and means" was the second most common elements. The elements of "consequences", "action and reflection" were less represented in the textbooks, with the exception of the learning activity part. The types of practical reasoning process reflected were classified either as the entire process of reasoning being reflected or some of the process being reflected, or included in the body content. Most of these were some of the process being reflected. Since there were a lot of concept-oriented statements rather than questions, more practical reasoning questions should be developed to increase the reasoning process. In addition, a need exists to develop a variety of ways to utilize the entire practical reasoning processes in the textbooks to help teachers apply the practical reasoning processes to their lessons.
