The purpose of this study is to investigate secondary science teacher's concepts of good science teaching. To do these, I have developed a questionnaire composed of 32 good teachings on education content, instructional method, instructional environment and atmosphere and assessment categories. 136 secondary science teachers have participated in the questionnaire and were requested to show agreement. Additionally, they were requested to describe the best science teachings that they have experienced. Results are as follows: First, the best science teaching that science teachers thought is a teaching that is in full accord with students' level in education content category, a teaching with an energetic interaction in instructional method category, a teaching in a trustful atmosphere in instructional environment and atmosphere category, a teaching in which students could learn something through a teaching-related assessment in assessment category. Second, secondary science teachers thought that a self-directed learning, a differentiated instruction and a teaching with diverse materials are not important factors in good science teaching. Third, there is a difference between good teaching that secondary science teachers have conceived and good teaching that they have experienced. It shows that science teachers did not precisely understand what good science teaching is. Additionally, I discussed the need of finding a case on good science teachings and a support of an interaction-focused teaching.

The information represented by graphic is preferred more than by text to the game generation familiar to computer games in the cognitive style. The learning to solve the math problems represented by graphic is significantly effective to improve learner's problem-solving power in math education. In this paper, we proposed a method of graphic representation of mathematical sentences for effective learning of the game generation. The proposed method arranges the unit informations in the logical structure and represent the logical interrelation between the informations by symbols, line segments, or arrows using the graphic elements with good visibility for the game generation to recognize easily and to understand accurately the logical meaning. The proposed method is able to represent accurately the math sentences until the detail level that appears the tense and the voice of the sentences differently from the previous graphic representation method's ability. The proposed method could be used as learning tools and used widely to represent graphically mathematical informations for the instructional scaffolding of an educational game in oder that the game generation could learn effectively.

The purpose of this study was to investigate the current status of information and communications technology(ICT) uses of the faculty members at national universities of education and to provide guidelines for ICT in education. The survey was conducted to examine factors related to the use of ICT, including faculty members' abilities to use ICT with respect to gender, age, and previous experiences with computers and to analyze their relevance to instructional methods. The results of the survey showed that female faculty members and male faculty members in their sixties and those with less years of teaching career were more likely to need support for using ICT than the others. The direct instructional method and discussion were the most frequently used; discussion was positively correlated with ICT uses. It was also found that faculty members anticipated more difficulties in using ICT in class and needed to work in a collaborative way and learn more effective use of ICT in the teaching and learning process.

The purposes of this study were to inform the exemplary models of integrated science and mathematics and to analyze and discuss their similarities and differences of the models. There were two steps to select the exemplary models of integrated science and mathematics. First, the second volume (Berlin & Lee, 2003) of the bibliography of integrated science and mathematics was analyzed to identify the models. As a second step, we selected the models that are dealt with in the School Science Mathematics journal and were cited more than three times. The findings showed that the following four exemplary theoretical models were identified and published in the SSM journal: the Berlin-White Integrated Science and Mathematics (BWISM) Model, the Mathematics/Science Continuum Model, the Continuum Model of Integration, and the Five Types of Science and Mathematics Integration. The Berlin-White Integrated Science and Mathematics (BWISM) Model focused an interpretive or framework theory for integrated science and mathematics teaching and learning. BWISM focused on a conceptual base and a common language for integrated science and mathematics teaching and learning. The Mathematics/Science Continuum Model provided five categories and ways to clarify the extent of overlap or coordination between science and mathematics during instructional practice. The Continuum Model of Integration included five categories and clarified the nature of the relationship between the mathematics and science being taught and the curricular goals for the disciplines. These five types of science and mathematics integrations described the method, type, and instructional implications of five different approaches to integration. The five categories focused on clarifying various forms of integrated science and mathematics education. Several differences and similarities among the models were identified on the basis of the analysis of the content and characteristics of the models. Theoretically, there is strong support for the integration of science and mathematics education as a way to enhance science and mathematics learning experiences. It is expected that these instructional models for integration of science and mathematics could be used to develop and evaluate integration programs and to disseminate integration approaches to curriculum and instruction.

Circuit theory is a systematic study that analyzes and designs the most basic circuits in the field of electrical and electronic engineering. Circuit theory courses are organized as major courses for one or two semesters in the second year of university, so that electrical and electronic engineering students must learn. Experimental courses are being together organized for students to enhance understanding of circuit theory and cultivate the skills and the abilities of circuit design through experiments with actual circuits. This paper is a case study on the teaching method applied in electric circuit design and experiment courses to enhance the learning effect on the experimental education that supports circuit theory. To do this, we propose a 15-week instructional model consisting of theory study, simulation, experiments, and design projects. In the proposed model, the simulation and preliminary experiment preparation process are reinforced to complement the theoretical concept and the design project is introduced to acquire practical circuit design skills as engineers. The results of five-year operation demonstrate the effectiveness of the proposed model.

The purpose of this study was to design an interactive multimedia nutrition education program for preschoolers. Computer technology provides the opportunity to explore new and creative methods of delivering nutrition education to pre-schoolers. If this method is effective, more preschoolers can be reached with accurate and consistent nutrition education with less time and teaching staff. This program is a computer-based multimedia nutrition education program for pre-schoolers based on the Dick and Carey (Dick & Carey 2001) model of instructional design which includes analysis, design, development, and evaluation. The overall instructional goal was based on the needs of the target population. The needs assessment was a self-administered survey distributed to 1,426 parents of preschoolers, focusing on the need for preschoolers' nutrition education. The results of the survey indicated that parents wanted their children to learn reasons for eating nutritious food. Therefore, a program titled 'Nutrition Exploration' was developed with the instructional goal of teaching preschoolers the 5 Food Groups. To achieve this goal, the preschoolers were engaged in a game. They could earn colored jewels by completing the game in five sessions. The story line was that people living in a peaceful kingdom become sick after they lose the jewels. The learner takes an adventurous journey through five different countries to retrieve the jewels. These countries are 'Giwoon nahrah' (foods containing carbohydrates, such as rice and potatoes), 'Sangsang nahrah' (foods that are rich in vitamins and minerals, such as vegetables and fruits), 'Sooksook nahrah' (calcium-con-taming products such as milk), 'Teunteun nahrah' (protein-containing foods such as meat and fish) , and 'Gakeum nahrah' (products with high sugar and fat content, such as instant foods and soda). The learner who obtains five jewels in five different countries can save the kingdom. For the program to be effective and efficient, the multimedia had to be easy for the preschooler to enter, use, and exit. The verbal instructions enhanced child autonomy, and the program was developmentally appropriate so that the young child could easily manipulate the software. This research provides the basis for the continued development of computer-based nutrition education materials.

This paper analyzed the main contents of multiplication and division of fractions in elementary mathematics textbooks and workbooks aligned to the national mathematics curriculum. This paper first explored the adequacy of when to teach the contents, the connection of instructional flow across grades, and the method of constructing a unit to teach multiplication or division of fractions. This paper then analyzed in detail the contents with regard to the types and frequency of word problems, the types of visual models and frequency, and the process of formalizing the calculation methods and principles. It is expected that the issues and suggestions stemming from this analysis of current textbooks and workbooks are informative in developing new instructional materials aligned to the recently revised mathematics curriculum.
