JOURNAL FREE ACCESSThe purpose of this study is to make clear the trend of educational studies especially in relation to "earth science". The data analyzed in the present study are bibliographical data from Current Index to Journals in Education (CIJE). The educational research paper in 'earth science' is defined as the study which has at least one of the following 9 keywords: "earth science", "geology", "geophysics", "meteorology", "oceanography", "seismology", "soil science", "physical geography", "paleontology". This is because the other 8 terms in the list are narrower definition of "earth science" in ERIC's thesaurus. CIJE has data from 1969 to the present, and 1644 literature which had been published from 1969 to 1984 were taken in this study. The number of papers in 'earth science' was significantly greated for the year from 1977 to 1980 than for the other years taken in this study. Next the co-appeared keywords in those literature were analyzed by factor analysis and cluster analysis. The results of two analyses show that the total of 16 years is divided into three periods; 1969-1972, 1973-1980, 1981-1984. Lastly by using the factorscores of each keyword, the causes of the two factors, "new" "old", were specified. And to specify the essential keywords which caused the changes between first period and second period and between second and third, chi-square values were examined.View full abstractDownload PDF (1019K) -

JOURNAL FREE ACCESSMelanophore movement in teleost fish scales is a typical phenomenon in cell mobility and many reports concerning this mechanism have been compiled. In this paper an application of this physiological phenomenon to science education was studied. On natural science in junior and senior high schools, fish color changes are useful for an instructive observation as an example of the corporal responce against changes of enviroment or some external stimulus. In junior high school science, the movement of fish scale melanophores can be utilized for teaching material as an example of living animal cells. In senior high school biology, the melanophore movement can be utilized for a simple model or an experimental material demonstrating some functions of nervous systems and hormones. Further, the isolated scale from the teleost fish may be utilized as an experimental material for a model of nerve-effector in a training course of science teachers.View full abstractDownload PDF (1607K) -

JOURNAL FREE ACCESSIn this report, the term "amount of information" is used to put together knowledge, skills and so on through which each student can obtain correct answers to given tests. In order to measure the output of the amount of information from the input of that which the teacher gave the students during the lessons and which students got by studying mathematics by themselves, the author made a model in which the amount of information is likened to water, and found the transfer function and the response function in this model. Several of various coefficients are determined by using (1) a pre-fest for the amount of preliminaly knowledge and so on, (2) a post-test for that of each student's motivation and his memory and so on, (3) the rate between lesson hours and the average of the total hours when each student studied by himself in the period during a unit study. The results are discussed by using the average of a class for each response function values, and the correlation coefficient between the pre-test or post-test and the response function value.View full abstractDownload PDF (731K)
