JOURNAL FREE ACCESSProgress in our highly information-oriented society is accelerating every day as we approach the new century. Socially, great importance is attached to education, particularly mathematical education, to meet future needs. In this paper, we describes Japanese social background first, and try to forecast the situation in the near future around the next five years. A plan to make an efficient use of computer is introduced. It is based on the consideration about the entire curriculum and the integration of the existing uncoordinated attempts. Furthermore, we discuss about more abvauced use which includes the integrated learning environment and idea to apply the computer communication to mathematical education.View full abstractDownload PDF (800K) -

JOURNAL FREE ACCESSIn school education in Japan, astronomy education has been incorporated into the new curricula at elementary and lower secondary level. Students will be given a chance to observe heavenly bodies is the course of extra-curricular activities, and teachers will study teaching methods and develop related teaching materials on in-service training courses at teachers' centers. The Science Promotion Education Law aims at substantial improvement of the equipment and facilities for astronomy education. In terms of adult education, museums and science museums have many astronomy-related activities and the mass media also have a useful role to play. This report deals with the above points.View full abstractDownload PDF (1597K) -

JOURNAL FREE ACCESSWe have studied the possibility of introducing the high-temperature superconductivity into student experiments of general physics at (university) general education courses in an attempt to modernize them. In this paper, we describe the results of the following experiments : 1. Preparation of bulk samples, confirmation of Meissner effect, and measurement of critical temperature, T_c. 2. Measurement of temperature-dependence of electrical resistivity of a wire made by rolling Ag-sheath filled with a superconductor. The resistivity of such a wire is shown to decrease rapidly near T_c. 3. Superconductivity experiments usually require considerable time. In order to remedy such shortcoming a method of experiment was developed by which a superconductive sample is prepared and the phenomenon can be confirmed within about 50 minutes. Though this method is not suited for quantitative analysis, it provides an effective way in understanding the essence of the phonomena. Applicability of the high-temperature superconductivity in physics education can be expanded significantly by such a "quick experiment". 4. By heat-treating YBCO type superconductive substance at around 1OOO℃, a superconductive magnet was prepared. By combining the above experiments properly, the high-temperature superconductivity can be a modern and attractive experimental theme with versatile physics content.View full abstractDownload PDF (1345K)
