The aims of mathematical education are to improve uniformity and rigidity, and to apply to an information age which our society demands. One of the educational aims in the 6th educational curriculum emphasizes on the expansion of mathematical thought and utility, But, The change of contents in the text appears little. This means that mathematical teachers must actively develop the new types of problems. That the interests and concerns about mathematics lose the popularity and students recognize mathematics burdensome is the problems of not only teaching method, unrealistically given problems but abstractiveness and conceptions. Mathematical Modeling is classified exact model, almost exact theory based model and impressive model in accordance with the realistic situation and its equivalent degree of mathematical modeling. Mathematical Modeling is divided into normative model and descriptive model according to contributed roles of mathematics. The Modeling Applied Problems in the present text are exact model and stereotyped problems. That the expansion of mathematical thought in mathematics teaching fell into insignificance appears well in the result of evaluating students. For example, regardless of easy or hard problems, students tend to dislike the new types of mathematical problems which students can solve with simple thought and calculation. The ratings of the right answer tend to remarkably go down. If mathematical teachers entirely treat present situation, and social and scientific situation, students can expand the systematic thought and use the knowledge which is taught in the class. Through these abilities of solving problems, students can cultivate their general thought and systematic thought. So it is absolutely necessary for students to learn the Modeling Applied Problems.

The purpose of this study is to discuss about the role of the visualization as an effective method of teaching abstracted mathematics, to analyze visual materials in middle and high school mathematics and to suggest various visualized materials for teaching mathematics effectively. Though formal, symbolic and analytical teaching method is a major characteristic of mathematics, the students should be taught to understand through intuition and insight, and formalize the mathematical concepts progressively. Especially the sight is one of the most important basics of cognition for intuition and insight. Therefore, suggesting mathematical contents through the visual method makes the students understand and formalize the mathematical concepts more easily. In this study, we tried to investigate the meaning and role of visualization in mathematics teaching. And, we discussed about the four roles of visualization in the process of mathematics teaching and learning confirmation and memorization of the mathematical truth, proving theorem and solving problems which is one of the most important purposes of teaching mathematics, According to the roles of visualization, we analyzed visual materials currently taught in middle and high school, and suggested various visual materials useful in teaching mathematics. The investigated fields are algebra where visual materials are little used, and geometry where they are use the most. The paper-made-textbook can't show moving animation vigorously. Hence we suggested visual materials made by GSP and applets in IES .

This study proposed task-based teaming strategies as a means of fulfilling the demands and goals of the 7th national science curriculum. Task-based learning is based on the use of a series of activities whereby a teacher presents students with tasks related to daily lift and the students solve the tasks by themselves using various methods and thought processes and then present and discuss their results with each other. The tasks are selected from the 6-grade science textbook, are reconstructed and are then given to the classes. The tasks include whole class activities as well as individual activities related to the interests, abilities, and concerns of the students. The purpose of this study was to verify the effects of task-based learning classes on the science process skills and the scientific attitudes of elementary school students, when applied to 6th grade students. For this, the task-based learning activities were applied to an experimental group and expository teaching was applied to the comparison group. Both groups were given a pre-post test on science process skills and scientific attitudes. The results indicate that task-based loaming is very effective in the development of science process skills and scientific attitudes.

In this study, we investigated elementary school teachers' and students' perceptions of the reading materials in science textbooks. Participants were 181 teachers from 23 elementary schools who were teaching science and 643 third- to sixth-grade students from 12 elementary schools. A questionnaire for teachers consisted of 18 items and a questionnaire for students consisted of 11 items about their perceptions of the reading materials in science textbooks. Nine to twelve items, according to grades, examining the actual uses of each reading material in science textbooks were also included to both questionnaires. The results indicated that teachers have positive perceptions about reading materials and frequently use them in case of needs for supplement and/or enrichment of science learning. Novice teachers were found to have less positive perceptions about reading materials than expert teachers. Over 70 percent of students responded that they read all reading materials. Fifth- and sixth-grade students were tended to have less positive perceptions about reading materials than third-grade students. Finally, students tended to have more positive perceptions about reading materials than their teachers.

This paper describes the types of models that biology majors use and how they go about making their models in learning key concepts in biology such as the cell membrane, cytoskeleton and cell structure. Initially, a total of 44 biology students from all year levels enrolled in the second semester of calendar year 2008-2009 were asked to make their respective models of the cell membrane, cytoskeleton and cell structure. They were also asked to answer an open-ended questionnaire. Of the 44, only 20 (five from each year level) were randomly selected for a one-on-one interview. Results showed that the student-generated models from all year levels were mostly analogies, some textbook definitions and occasional drawings. In making their model, students first read the text; second, outline similarities in structure and function or both; and third, make the model. Data suggest that models are good diagnostic tools for identifying critical thinking skills of students. In this case, students mostly demonstrate the ability to recognize similarities in structure and function between the concept and their model. Some senior students demonstrated integration and reflective thinking in making their models. Thus, more opportunities for student-generated models must be available if students were to develop integration and reflective thinking in their models.

As new technologies change a society, librarians need to understand and adapt to technology innovations. However, most innovations that librarians are supposed to adopt are government-driven or top-down changes; and there have been very few studies conducted to identify any patterns or consistencies in librarians' perceptions of innovation. This paper, therefore, has two research purposes. First, it introduces the Concern Based Adoption Model (CBAM) as one method to gain a deeper understanding of how librarians see such changes. Second, this study identifies school librarians' concerns regarding digital textbooks in South Korea applying the CBAM theory. The test signifies that school librarians present a typical non-user profile, and the pattern anticipates a potential resistance to digital textbooks. Also, it discovers the less experienced and innovator librarians had higher concerns across every stage. The findings underscore a need of various interventions. The CBAM theory suggests, in terms of intense Stage 0 and 1, it is required for school librarians to have events to gain information about digital textbook implementation. Regarding targeted interventions, since the biggest gaps occurs in Stage 4, Consequence and Stage 5, Collaboration, according to school librarians' experience and adoption style, new school librarians need stronger engagement with the community, which including associations, mentors or peer support, and collaborating with public libraries; innovator school librarians require opportunities to test and present their use of digital textbooks (Hall and Hord 1987).

This study is intended to develop a CAI program on the topic of flowing rivers and to investigate how 4th grade students' concepts of it change through this program. The CAI program is made using the GREAT II copyright tool based on a typical 4th grade science Korean textbook. This program consists of 5 sections, which are introduction, rain waters, running waters, river waters, and activity. All contents are animated. Students are 30 4th grade students. One instrument is used how to investigate the concept change of the flowing rivers. The instrument is called the Identification of Flowing River Concept Test(IFRCT, Appendix), which is of a two-tier type and has 8 items. Data are collected before and after the instruction using this program. Data are classified as a scientific model, a naive model, or a "no" model, based on criteria used by Vosniadou(1989). Data are compared. The results show that 4th grade students after the instruction using this program hold a more scientific model on the flowing rivers, than before the instruction using this program. Therefore, the author urges science teachers to use the CAI program to teach students about the flowing rivers.
