It is important for student to participate in classroom actively in order to raise effeciveness of education. In this study, we have considered the science textbooks as major factor which influence to participation in the science class, and aimed to find the problems of current sicence textbooks as tool to promote students' participation, and the improvement method. The questionnaire which include the questions to ask requirements for and problems of science textbooks for learner-centered instruction was developed, and then 99 science teachers and 821 students answered the questionnaire. As a result, students responded that current science textbooks lacked explanation, had many of difficult words and complex sentences, and were uninteresting. Teachers responded that current science textbooks had large in quantity, were written knowledge centered, and lacked of link with real life, and of story. To conclude, science textbooks revitalizing the students' participation had to strengthen the link with real life, increase students' activities, use words and sentences appropriate level for students, strengthen storyline, and provide sufficient chances to check the students' understanding by themselves.

The major purposes of this study were 1) to present a desirable guideline for writers who would develop the new Introduction-to-Industry textbook through the comparative analysis of 4 different kinds of current Introduction-to-Industry textbooks, 2) to help educators, who make national college entrance exam in the vocational inquiry area, make good exam items with the results of the study, and 3) to offer effective methods of teaching and learning in the field of industrial education with them. Research method used in this study was mainly literature review with the scrutinization of the literature related to the Introduction-to-Industry textbooks. Results of this study showed that all textbooks compared do mostly comply with the national writer's specific guidelines for the Introduction-to-Industry textbooks. However there were varieties for the all textbooks in a sense of deployment balance for the contents of the textbook chapters. There were also considerable differences for the deployment of supplementary materials, evaluative materials, visual materials and etc. according to the characteristics of each textbook. The degree of the connectivity between the textbooks and the national college entrance exam in the area of the vocational inquiry was similar for the each textbook. However, it was not good enough for the students to study one textbook for the preparation of the exam in the vocational inquiry area because the problems in the exam were set in the range of covering the all different kinds of textbooks by the examiners.

With a significant role of textbooks in shaping students' opportunities to learn, textbook analysis is essential to reveal these opportunities to learn the concept of area and volume. This research aims to show how the Korean textbooks pace students' learning of area and volume across grades by scrutinizing the textbooks with students' developmental sequences, called learning trajectories. Tasks about area and volume in all Korean elementary textbooks (grade 1 to 6) are coded with the specific developmental stages suggested in learning trajectories. As a result, we find considerable misalignment between the textbooks and the learning trajectories. The textbooks provide opportunities to experience developmental progressions of area and volume later than ages suggested in the learning trajectories. In addition, learning opportunities are significantly concentrated in grade 5 for area and grade 6 for volume with heavy emphases on applying formulas of area or volume. The findings from this research provides important implications concerning design of textbooks as well as improving students' opportunities in the mathematics classrooms.

Understanding decimal numbers is important in mathematics as well as real-life contexts. However, lots of students focus on procedures or algorithms of decimal numbers without understanding its meanings. This study analyzed teaching method related to decimal numbers in a series of mathematics textbooks of Korea, Japan, Singapore and the US. The results showed that three countries except Japan introduced the decimal numbers as another name of fraction, which highlights the relation between the concept of decimal numbers and fractions. And limited meanings of decimal numbers were shown such as 'equal parts of a whole' and 'measurement'. Especially in the korean textbooks, relationships between the decimals were dealt instrumentally and small number of models such as number lines or $10{\times}10$ grids were used repeatedly. Based these results, this study provides implications on what and how to deal with decimal numbers in teaching and learning decimal numbers with textbooks.

The declination is an important concept because it is the underlying concept to understand the plate tectonics and also is used to decide one's location by using the compass and the map in real life. So this study surveys the description of declination being used in six of the seventh curriculum earth science II textbooks followed by the investigation of the possible of misconceptions that the highschool students might have. Utilizing an inventory of key concept, this study examines the actual misconceptions of highschool students, and investigates the relationship between misconceptions and textbooks. As a result, highschool students possess some misconceptions particularly with respect to the magnetic north pole which is caused by a lack of explanation about declination and by a wrong illustration. Therefore we suggest that detailed explanations of declination with non-dipole effect and precise illustrations be provided in the textbook for students th have a better understanding about declination.
