    Symbolic distance effect (SDE) in macroscopic time concept was investigated. Subjects were six university and high-school teachers and fifteen university students. They was presented with pairs of printed names of animals; an ameba, a jellyfish, a killi-fish, a lizard, a dog, a gorilla and a mankind. They were instructed to choose the member whose appearance is older on the earth. The reaction time (RT) to choose the older member varies inversely with the steps between their order on the evolution. This finding shows that the judgments are based on some kind long-term memory representation. The data suggest that Ss have made macroscopic time concepts along the evolution.

    We report our experience of the special course which was organized so that all the students should participate in it actively. Each student chose for himself a theme related to physics from the field of medical sciences and life sciences. After working over the theme through various literatures, each student presented a report together with a short abstract to which about 10 keywords of the theme were also attached. Making use of word-processing software on microcomputers the students typed these materials in Japanese. A collection of the abstracts into one floppy disk allowed us to form a small-size database by which one can search a necessary information of the relevant field rather easily. We published a booklet, a collection of the abstracts, and used it as a material for a mini : conference where selected students from each field gave short talks. The main feature of the present course is an introduction of information-science concepts and techniques, such as keywords, abstracts, database and so on, into the educational course. We organized the main content of the subject on the basis of research activities of the students themselves, who could experience various working processes through the course. In this article we discuss the educational meanings of such a lecture form, its consequences and reactions from students as well as problems for further considerations. As show-case an example is given to demonstrate how to use the software developed by us in constructing the database.

    A reflectometer was manufactured by the use of cheap materials such as solar cells, an electric bulb, a drawing paper, a sheet of acrylic resin, and a pipe of polyvinyl chloride resin. The capability of it was similar to that of the commercially available reflectometer. This was used to the determination of black-and-white ratio in figure, the estimation of line width, thd measurement of the starch-iodine reaction rate, and the determination of carbon dioxide reacted with a BTB testpaper. A favorable result was obtained to use it as teaching materials in each case.

    The purpose of this paper is to develop an effective diagnostic system which asseses individual differences of the learners and give useful suggestions for mathematics teaching. The individual differences are assesed in the following aspects; attitude toward mathematics, studying method, basic competence and achievement score of mathematics. The questionnaire was used to evaluate the attitude and the studying methods of students. Also, the basic competence test which measures how well the students are prepared for high school mathematics was developed. These tests were administered to over 1500 high school students. Next, we extracted three factors from the "attitude" questionnaire, which are "valuation","weakness" and "accomplishment", and also three factors from "studying-method" questionnaire, which are "active attitude", "strategy" and "skills". We found out that basic competence is neccesary and useful to predict progress in mathematics. A diagnostic system should be constructed based on these findings.
