JOURNAL FREE ACCESSRegeneration of the caudal fin of killifish or its fin formation in the fry involves many basic phenomena of the morphogenes in vertebrates and presents an available teaching material for the in service program of science teachers. The present works are summarized as follows : 1) After amputation of caudal soft fin rays of killifish, Medaka (an orange red variety), the killifish was reared in water containing 0.001% chlorinated lime solution for 60min resulted in the abnormal regeneration or the retardation of regeneration. 2) The regeneration potency of the caudal fin of killifish appears to be associated with the density of the mesenchymal cells in the early stage of the blastema. 3) A simplified method for a preparation without using microtome, which was described in this paper, is useful for the observation of animal cells in biology education of junior and senior high school.View full abstractDownload PDF (656K) -

JOURNAL FREE ACCESSThe advancement of biotechnology, including gene-technology, and life science in recent years is remarkable. Bacteria such as Escherichia coli (E.coli) contributed enormously to that advancement and are essential for research in those fields. We have developed simple handling methods for E.coli and for the observation of the chemotaxis of that bacteria for biological education in high schools. For sterilization, an autoclave was not neccessary; the incubation of the culture medium in boiling water bath for one hour and the clean-up of equipment by use of 70% ethanol were enough. For the growth of E.coli, shaking bath was not neccessary; non-shaking incubation of the culture medium with shallow depth was sufficient. For harvesting E.coli, centrifugation was not neccessary, we could harvest through filteration of the medium by use of ordinary filter paper. The chemotaxis of E.coli was easily observed as follows: (1) Uniformly spread E.coli on a semi-solid agar plate came together at the circumference of the small filter paper containing the attractant during the incubation at 30℃ for several hours and we could recognize a muddy ring formed by the attracted bacteria. (2) For the observation of attracted E.coli under a microscope by Adler's method, a U-shaped glass tube, which is very difficult to make by oneself, is neccessary. Through our improvement, we could very easily observe bacterial chemotaxis by use of hole-side glass. We shall describe quantitative assays of the bacterial chemotaxis in the following paper.View full abstractDownload PDF (797K) -

JOURNAL FREE ACCESSDevelopment of the environmental education in the United States is on a higher stage than that in Japan. In this study, we examin the trend of environmental education on teacher education in the United States. Namely, the following subjects are considered. 1. Teaching systems for Environmental Education. 2. Curriculum of environmental education for undergraduates. 3. Curriculum of environmental education for graduates and inservice teachers. 4. Environmental Education Intern. 5. Practice of using local expert. In conclusion, we suggest a way for improving the environmental education on teacher education in Japan. 1. Introduction of interdisiplinary curriculum of environmental education to graduate level. 2. Establishment of council which coordinate the curriculum of environmental education in colleges and universities. 3. Introduction of environmental education intern as presservice teacher education.View full abstractDownload PDF (765K) -

JOURNAL FREE ACCESSResearch on the actual conditions for soil education and teachers consciousness for soil education was carried out by questionairing on 580 teachers of primary and junior high-schools. From the answers to the questionaire, following conclusions were obtained. 1. The method of education on soil is not reasonably oriented. 2. Over 60% of answered teachers have the opinions that the education on soil in the school should be improved. 3. The methods of improvemeat are rather complicated. The suggested most reasonable method was to give the lessons on soil science systematically in the course of Science and Civics. 4. Considerable numbers of teachers did not have the chance to get enough experience in education on soil in teacher-training colledges.View full abstractDownload PDF (939K)
