In this study, we develop a capacitive rotating angle sensing system using a hand-made 1 kHz oscillator, field-effect transistor (FET) amplifier, and tester through a physics experiment conducted in Ryukoku University. Physics majors of the university can study the fundamentals of electronics through this system because it uses electronic…

This study focuses on students' understandings of a liquid-gas system with liquid-vapor equilibrium in a closed system using a pressure-temperature ("P-T") diagram. By administrating three assessment questions concerning the "P-T" diagrams of liquid-gas systems to students at the beginning of undergraduate general chemistry…

A high-school third-year or undergraduate first-semester general chemistry laboratory experiment introducing simple-cubic, face-centered cubic, body-centered cubic, and hexagonal closest packing unit cells is presented. Latex balls and acrylic resin plates are employed to make each atomic arrangement. The volume of the vacant space in each cell is…

This research revealed that metal ions with different charges could significantly affect the viscosity of aqueous sodium carboxylmethylcellulose (CMC) solution. On the basis of an Ostwald viscometer, an improvised apparatus using a dropping ball for examining the viscosity of liquids/solutions has been developed. The results indicate that the…

Compares the university training of scientific personnel in each country to see how strengths are nurtured. Discusses curriculum content as well as the societal and cultural factors which determine the educational environment. Describes entrance examinations, undergraduate programs, curricula, and societal views. (CW)

This document describes some of the variables influencing the education of science teachers in Japan. One consideration involving the preservice education of science teachers relates to the type of undergraduate program. Both the Teacher Training System (TTS), in which the undergraduate students are based within the college of education, and the…

Japan's postwar research and development (R&D) efforts have passed through several phases to bring the nation to what may be called "relative parity" with the United States. This document examines the characteristics of Japanese and U.S. R&D efforts. Topics compared include: national science resource patterns; science and…
