According to the 2007 national curriculum amendment, new 'informatics' textbooks have been used since 2010 as a textbook for middle school first graders and will eventually be used in other grades. However, only a few studies that have evaluated the 'informatics' textbooks, have been performed. What is worse is the fact that none of the evaluating tools even exist. Therefore, we propose the criteria of selecting 'informatics' textbooks in middle school. Its contents can be summarized as follows: First, this paper classifies previous studies on textbook evaluation into general criteria of selecting textbooks, method of textbook analysis based on how inquisitively students can learn and previous studies which analyzed existing secondary school 'informatics' textbooks and propose the criteria of selecting 'informatics' textbooks in middle school. Second, using the proposed selection criteria for 'informatics' textbooks and other evaluation criteria, five kinds of informatics textbooks were analyzed. Furthermore, it is expected that we can use the selection criteria as a material to choose the new 'Information science' textbooks, and to suggest alternative directions of future studies in the area of evaluating 'Information science' textbooks.

The purpose of this study was to explore what a science lesson using a digital textbook looked like and what kinds of implications could be drawn from the lesson. The study qualitatively described a 4th grade science lesson in the unit of Earth and Moon, analyzed the structure of the lesson, and critically interpreted the meaning of it. It was revealed that the introduction of a digital science textbook did not bring about changes in the already patternized structure of elementary science instruction as well as in the manner of classroom interaction. The result was followed by discussion concerning the ways the use of a digital textbook could change elementary science instruction and enable new types of classroom interaction. It was suggested that negotiations should be reached about the nature of digital science textbooks and their developments and that the teacher's own pedagogical roles in the science classroom should be improved.

The purpose of this study was to analyze effect of nutrition education after executing education nutrition with the nutrition education textbook, reconstructed 12 units, focused on older elementary school children and to evaluate interest and understanding of textbook. The subjects were 4th grade children. The results were as follows. The most interesting lesson contents was 'obesity(16.3%)', and the next were 'food poisoning' (13.3%), 'kimchi'(13.3%), and 'Korean table manners'(10.2%) in the 12 unit. Children who attended education nutrition answered 'interesting'(94.1%), 'understand easily'(97.1%) about the developed textbook. With regard to change in nutrition knowledge after education, the percentage of correct answers was increased in most of question except 'reason of snack' and 'weight-control'. And the total score of nutrition knowledge was risen(p<0.01), because the ratio of correct answer of 'importance of breakfast'(p<0.05) and 'nutrition labeling'(p<0.01) was improved especially. The ratio of desirable snack time 'between lunch and dinner' was higher after education(91.2%) than before(55.2%)(p<0.01). After education, the choice of 'Fruit and vegetable' of which desirable snack food was increased. Both the choice of 'bread' and 'fast food', a factor of oversupply calorie, was decreased. And after education, the percentage of sound snack place 'home' was improved. In regard of a meal environment, the percentage of 'every wash hand before eating' is 65.1% and there is scarcely change after education. Before education, children answered 'use it rightly'(82.4%) about 'how to eat with spoon and chopsticks', but it is lower after education. The ratio of 'leave food sometimes or always' is 47.1% before education, and the ratio of leftover food tend to decreased in school lunch. Relate to reason of leftover, the percentage of 'because of hate food' tend to decrease. This results suggests that the activity-centered nutrition education can help to change food behaviors and increase nutrition knowledge level of school children.

This study was conducted as a learning project for 20 pre-third graders in high school by means of math textbooks, G+, and sample questions from previous CSAT as learning tools for 9 weeks from Dec. 24, 2015. The purpose of the study was to develop 'math textbook project learning(MtPL)', a mixed learning method combined on-line with off-line, and analyze the effects of MtPL on the affective domain of high school students. As a result of the study, it was found that MtPL had positive effects on self-efficacy and self-confidence of students, while the collaborative learning using a textbook and teacher's role worked as instrumental motivation in mathematics learning. The result also implies that the perception of high school students, who think to resolve more difficult math problems to succeed in CSAT, about mathematics learning method has to be modified. Furthermore, it is shown that the preparation of CSAT by utilizing textbook and the use of textbook in math learning have been worked positively for the students.

This study focuses on cuisenaire rods that can be used when teaching fractions to elementary school students. First of all, this study critically examines the use of cuisenaire rods in learning of fraction proposed by various researches. Then, based on this review, this study explores in detail the use of cuisenaire rods in teachers' manuals developed from the revised curriculum by 2009 and in lessons related to fraction. The results of this study show that there are subtle differences in how to use cuisenaire rods in learning fractions and these subtle differences have a significant impact on students' understanding of the fractions. Therefore, the teachers should be able to accurately grasp the differences and utilize appropriate methods for teaching purpose. The followings are some of the implications for teachers or textbook developers when using cuisenaire rods in fraction learning: First, we should use cuisenaire rods in ways that can fully exploit the interpretations of the fraction as a part-whole and the fraction as a ratio. Second, we should focus on quantitative reasoning with unit to determine what each cuisenaire rod refers to. Third, it is necessary to take a more careful and sensitive approach to the use of cuisenaire rods. Teachers and textbook developers should constantly explore ways to make good use of mathematical manipulatives to help students understand conceptually in fractional learning. Furthermore, when teaching various mathematical topics using different manipulatives, I expect that there will be sufficient discussions and specific studies on how to use each of these manipulatives.

The main purpose of this study is to examine the use of 'a gente' in Portuguese, and to discuss what to consider educationally. We examined the origin and style of 'a gente', grammaticalization process phase, personalization level, and variations in use in terms of linguistic and social aspects, and confirmed that 'a gente' is showing an increasingly high frequency of use in Brazil. And in order to find educational considerations, we observed how 'a gente' was handled in Portuguese textbooks for foreigners, and analyzed data obtained through interviews with three Korean students studying Portuguese in Brazil. Considering the importance and frequency of use of 'a gente', which is used in the third-person singular form, the section about 'a gente' in grammar and textbooks seems to be very insufficient. Therefore, the contents of textbooks that do not correspond to the actual use of language should be actively revised according to changes in the reality of language use. In addition, the instructor should not be bound by traditional use, but must include 'a gente' in the personal pronoun section of the textbook for efficient education, and actively reflect the more practical usage to educate.

The 4th industrial revolution is coming. In order to prepare for the new learning environment with it, we may need digital mathematics textbooks that fully utilize all possible technologies. So various attempts have been made in elementary and middle school mathematics education. However, despite the importance of higher mathematics, we haven't seen a best possible math digital textbooks yet in Korea. In this paper, we introduce our new model of interactive math digital textbook about Linear Algebra/ Calculus/ Differential Equations/ Statistics/ Engineering Math. Especially, this manuscript focuses on our experience of using digital contents and interactive labs for developing a new model for linear algebra digital textbook. We introduce our works on linear algebra digital textbooks which include pdf e-book, web contents, video clips of lectures, interactive lab. Using this linear algebra digital textbook, students can freely use any mobile devices to access diverse learning materials, lessons, and hands-on exercises without any limitations. Also, times saved in the computation, coding, and typing process can be used to have more discussions for deeper understanding of mathematical concepts. This type of linear algebra digital textbook, which contains all interactive free cyber-lab with codes and all lectures for each sections, can be considered as a new model for the next generation of math digital textbook.
