This study explores how an elementary school homeroom teacher who continued to lecture, can use diversified science teaching methods for learner-centered instruction. Using an auto-ethnographic approach over the course of a year, self-memory data, facebook diaries, class diaries, and interview data of an elementary teacher's day-to-day preparations and practice of elementary science, in the context of a Korean elementary school, were collected. The data was analyzed through cultural historical activity theory, examining how the interplay of key elements (i.e., the subject as a homeroom teacher with instructional expertise, norms, community, division of labor, tools, and goals) was characterized within and across distinct two-activity systems, and how these elements shaped the teacher's teaching methods into either lecture format or diversified teaching. The study revealed that a non-cooperative community, lack of division of labor, and norms that neglect preparation for science class were the elements that perpetuated the lecture format, and that a contradiction between goals and tools occurred in the activity system. However, these elements were able to be transformed into a cooperative community, shared labor, and norms that saved preparation time for both science class and diversified teaching methods, and those changed elements facilitated the teacher in using diversified teaching methods (e.g., experiments, subject-integrated classes, field work), thereby mitigating the contradiction. This study also discusses that diversified teaching methods can be facilitated when dealing with norms, community, and division of labor elements in an elementary school context as well as improving individual teachers' instructional expertise.

The environmental education with ideal teaching tools (e.g., a small-scaled experimental kit) is essential for raising the public's, especially student's, awareness of many environmental issues. This study was undertaken to develop a do-it-yourself model instrument of acid rain and estimating its applicability to the environmental education. Our novel model tool consists of a body (17 cm width, 6 cm depth, and 17 cm height), an acid gas injector, acid four rain reservoirs, and a drop supply pump. An alternative model instrument that can be more readily assembled was also suggested. Based on our novel approach, we carried out several model experiments with educatees (i.e., high school and college students, and adults). The results of questionnaires indicated that educatees achieved a very deep understanding of acid rain through an experienced model experiment. A 77 to 89% of educatees experienced the reappearance experiment of acid rain by our model instrument felt that it was very useful as a teaching tool of environmental education.

Quantum chemistry has many concepts that are either abstract or counterintuitive, giving students difficulties in understanding them. Fortunately, the advancement of web technologies provides us with hordes of powerful tools to produce rich multimedia web applications that supplement traditional classroom teaching. In this paper we present an approach to address this issue that combines interactive simulations and visualization on the web browser using Shockwave technology. With several examples, we show how to take advantage of the features of the Shockwave technology in developing web-based course material with ease.

This study examined what questions posed, and for arranging the matters, what decisions made, what practices put into by elementary preservice teachers during his or her enacting and reflecting mathematics teaching. Analysis of the study focused on the mathematics instructions practiced by four participants in practicum for senior students. Their own questions raised by each one in the instructional designs, performances, and reflections were picked out and categorized by five dimensions of mathematics instruction; the nature of classroom tasks, the role of the teacher, the social culture of the classroom, mathematical tools as learning supports, and equity and accessibility. Their instructional decision-makings and action-takings for answering to these questions were analised.

This paper is concerned with education courses operating practices for basic computer literacy training. In this study, we propose an example for students to effectively measure and evaluate the achievement of defined ability in the performance measurement and analysis, learning objectives and learning outcomes set in operation throughout the course. Through research and development use case presents the tools for teaching method and effective and objective measurement of the related subjects. And based on the results, we propose the possibility of utilizing NCS-based course operation and education certification. In this study, the measurement process is based on the association with the objective of the development and operation, and measurement tools, measuring tools for measuring learning outcomes associated with the curriculum design methods for the measurement and evaluation of the case of the operation of the course units of learning outcomes and the method proposed.

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.

The purpose of this study is to suggest didactical principles for using mathematical teaching aids and to applicate didactical principles in a relation with curriculum. First, we meta-analyzed related literature to suggest didactical principles for using mathematical teaching aids. And we suggested didactical principles as follows: principle of activities, principle of instruments, principle of learning. Using mathematical teaching aids with didactical principles in mind would help avoiding situations in which mathematical teaching aids are only used as interesting tools. Second, we concretized the meaning to applicate didactical principles and use mathematical teaching aids in a relation with curriculum. We considered domain, key concept, function, achievement standard, which were presented in the curriculum of mathematics, and suggested concrete activities. Third, we produced two designs for lessons on incenter and circumcenter of triangle and linear function's graph using mathematical teaching aids.

In children education, it takes a much time for teachers to prepare teaching materials and tools. Most teaching materials and tools consist of pictures so that children may easily understand the contents of a study. If instructors free from laborious work for preparing these materials, they can provide children with better education by focusing more creative works. In this study, we manufactured many picture data which are used in children education, and developed a program that is used by teachers for the purpose of utilizing these pictures according to study topics. This program provides a feature that easily search more than 3700 pictures according to subjects and areas, and also provides various editing facilities such as expanding, reducing pictures and writing statements.
