The purpose of the study was to produce resources to help develop instructional methods and programs for school science to reduce gender differences in science achievement by analyzing TIMSS-R results according to item type, benchmark, and content category. Korean male students performed higher than Korean female students and gender differences of Korean students were higher than international means in all item types including multiple-choice, short answer, and extended response type. GDI(Gender Difference Index) of Korean students was lower than international mean in top 10% benchmark but higher than international means in other benchmarks. Korean male students also exhibited higher performance than Korean female students in all content categories except scientific inquiry and the nature of science category. Regarding items that GDIs were higher than 10, the number of items belonged to life science and earth science category was relatively larger and a high percentage of them was not included in school science curriculum. In addition, the items were equally distributed in each performance category. In sum, the study showed various gender differences according to item type, benchmark, and content category. The results could be used to find appropriate instructional methods to reduce gender differences in science achievement.

Elementary science textbooks are the major instructional materials which contain sceientific objectives to be acquired by students. The purpose of this study is to analyze the development system, to evaluate the inquiry activity in current elementary science testbooks, and to make suggestions for the improvement of them. The questionnaires were administered to 116 subjects that participated in development of the 5th elementary science textbooks, and 86 of the subjects responded. Based on the data gathered and analyzed in this study, the major findings are as follows. First, regarding the analysis and evaluation of elementary science textbooks. 1. The instructional objectives in elementary science textbooks are analyzed. The proportions of comprehension objectives is 38%, scientific inquiry process objectives 21%, experimental skills objectives 7%, scientific attitudes and interests objectives 4%. 2. The science concepts in elementary science textbooks of the 3rd grade required the preconcrete operational level(82%) and of the 6rd grade required the postconcrete operational level (73%) by J. Piaget 3. The inquiry activities in elementary science textbooks are emphasizing gathering and organizing results and evaluation, and hypothesizing and designing an experiment Inquiry index of the elementary science textbooks is 76. This is significantly higher than 35${\sim}$50 of America and U.K.. 4. The number of questions per class hour is mostly three, and most of them require the students to explain phenomena in nature or in experiment Second, regarding the development system of elementary science textbooks. 1. The budget for and the period of the development of elementary science textbook should be expanded. 2. For the improvement of elementary science textbooks, more abundant resources and time should be used for the basic study and the field trial of textbooks. 3. The elementary science textbook must include the affective objectives as well as the scientific knowledges and scientific inquiry skills. 4. It is not desirable to assign equal number of pages to the content of physics, chemistry, biology, and earth science. 5. Closer cooperation system is needed among the ministry of education, development research center and the field trial schools.
This study presents the process and outcomes of developing mathematical-informatics linkage·convergence class materials, based on previous research findings that indicate a lack of such materials in high schools despite the increasing need for development of interdisciplinary linkage·convergence class materials In particular, this research provides insights into the discussions of six teachers who participated in the same professional learning community program, aiming to create materials that are suitable for linkage·convergence class materials and highly practical for classroom implementation. Following the material development process, a theme-based design model was applied to create the materials. In alignment with prior research and consensus among teacher learning community members, mathematics and informatics teachers developed instructional materials that can be utilized together during a 100-minute block lesson. The developed materials utilize societal issue contexts to establish links between the two subjects, enabling students to engage in problem-solving through mathematical modeling and coding. To increase the validity and practicality of the developed resources during their field application, CVR verification was conducted involving field teachers. Incorporating the results of the CVR verification, the finalized instructional materials were presented in the form of a teaching guide. Furthermore, we aimed to provide insights into the trial-and-error experiences and deliberations of the developers throughout the material development process, with the intention of offering valuable information that can serve as a foundation for conducting related research by field researchers. These research findings hold value as empirical evidence that can explore the applicability of teaching material development models in fields. The accumulation of such materials is expected to facilitate a cyclical relationship between theoretical teaching models and practical classroom applications.
The purpose of this study was to analyze the differences in the understanding level of the Korean traditional seasonal customs during summer (i.e. Buddha's birthday, Dano festival, Yudu festival and Chilseok) before and after the execution of a educational program concerning seasonal customs and determine if elementary school teachers recognize a need for this kind of educational program. The subjects of this study were 168 students in the 4th grade at two elementary schools (84 students each for the experiment group and the control group) and 249 teachers at the elementary schools in Yangju city. The major results of this study are as follows : First, it was shown that there is no significant difference in the understanding level of seasonal customs between the experiment group and the control group in the pre-test, but after carrying out the educational program, it was indicated that there is a statistically significant difference between the experiment group and the control group in the post-test. Second, in addition to strongly pointing out the necessity of seasonal customs education, the teachers recognized that it is desirable to teach seasonal customs to students through the discretionary activity class corresponding to the seasonal divisions in the year and that it is especially important to perform the educational activity through traditional plays and to utilize audio-visual media. Also, teachers hoped that a seasonal customs program suitable for elementary school students would be required, along with the development of instructional materials, and finally that the schools need to further develop teacher training through field inspections and practice.
The development of personal computers and the Internet led to changes of instructor-student and student-student relationships in design education. New resources of design education with proper materials and tools have to be offered for teaching and learning. The purpose of this research is to develop Basic Graphic Tools(BGTs) on screen that help students to practice the design principles, and to evaluate the BGTs' usability to enhance the credibility of extra tools for online design learning. The BGTs has to be developed to minimize the gap between the online and traditional classroom settings and to maximize the diverse advantage of lecture content driven from technology. Students were given certain design requirements to explore BGTs and a learning guide/performance test after the lecture to evaluate the tools. The test was performed under the e-learning program serviced by C college. This research has presented some encouraging results and raises questions toward future work: how do BGTs impact the feasibility of an online design lecture.
Within a context of rapid technological change and shifting market conditions, the education environment requires new paradigm of education delivery. In accordance of such a technological progress, distance education system, which makes the learning take place at anytime anywhere, overcoming barriers of time, or distance, is emerging as a mainstream of education delivery replacing the convectional one way delivery system from instructor to learners. This paper aims to introduce the development principle and algorithm about Instructional System Desgin(ISD) module, a part of a total solution for distance education services. It was developed on Linux, a free Unix-type operating system. Linux supports so various network protocols, sharing the network resources in a smooth way, that it is able to integrate with other operating system very easily, especially with Windows NT or Windows 2000 servers. In terms of quality, it never falls behind the windows products which are commercially available only. It is a right operating system for the such a school environment that is usually limited in budgets. The development environment of the distance education solution to which ISD module belongs is composing of Apache server for web server, lava bean based on components for ISD module, PHP, server-side scripting language, for HTML documents and MySQL for DBMS.

As the recent demand for human resources in science, technology, engineering, and mathematics (STEM), the development of professional STEM teacher is called worldwide. It is becoming a critical need in teacher education in order to educate student teachers, and prepare pre-service and beginning teachers for high quality of teaching competency. To promote the competency for $21^{st}$ century STEM teachers, the epistemology of technological pedagogical content knowledge (TPACK) is currently considered as the essential qualities of knowledge for highly qualified teachers. The aim of this study is explore the effect of case-based learning approach on TPACK competency of pre-service STEM teachers. In order to develop the pre-service teachers' competency regarding effective integration of technologies into teaching specific content areas, a series of innovative case study teaching in science and mathematics was presented to 43 participants of pre-service physics, chemistry, biology, mathematics, and computer teachers during a course of information and communication technology (ICT) in Education at Khon Kaen University, Thailand. After finishing a case presentation, the pre-service teachers were encouraged into a forum of critical open discussion by considering the potential impact of the case and the TPACK framework. They were investigated instructional design competency of using ICT tools into student learning process and their personal beliefs about ICT in educational process both before and after. The participant's reactions and learning was evaluated by using a self-reported questionnaire and an implementation log of content-specific learning process design, respectively. Results showed a change of their beliefs and the transformation of their TPACK competency in STEM teaching. In an effort to better serve the needs of high quality STEM teachers, the results of this study illustrated that the competency of TPACK could be particularly considered as a core attributes for future STEM teachers. By the way, case-based learning approach can play an effective part in preparing and professing the TPACK competency for STEM teachers.

This study analyzed the statistics contents in elementary mathematics textbooks in terms of an information-processing capacity, which is one of the math competencies emphasized by the 2015 revised mathematics curriculum. The findings of this study showed that the activities of 'summarizing and analyzing data or information' far outnumbered 'collecting data or information', 'interpreting and utilizing information', and 'using technological instruments or manipulative materials'. Lessons of collecting data or information were mostly present in the textbooks of lower grade-levels, where the range of data collection was narrow, and lacked adequate exploration of data collecting methods. Some lessons on utilizing information were not based on the interpretation of data, and using technological instruments or manipulative materials was merely introduced in teachers' manual and hardly introduced in the actual textbooks. Based on these findings, this study sought to suggest implications regarding the development of statistics contents in elementary mathematics textbooks in a manner to improve students' information processing capabilities.
