JOURNAL FREE ACCESSThe teaching materials for plant sciences should be efficient and convenient, providing maximum information with minimal requirements for labour, facilities and expenditures. A tachyplant, Arabidopsis thaliana (L) Heynh. (Cruciferae) may meet above qualifications; its short life-cycle, its small size and therefore its ability to grow large populations under laboratory conditions and to grow normally on the artificial media, its fecundity of seeds, its low chromosome number (2n=10), and the existence of numerous mutant strains. In the present study, we have examined the capacity and efficiency of this plant for teaching the plant life-cycle, various developmental phenomena through its process and its regulation by environment in the courses on experimental botany. In this article we will describet he simplest method of the aseptic culture in a test tube, and demonstrate some experiments (effects on growth and development of nutrients, light, temperature and gibberellin, a plant hormone) practicable in classroom.View full abstractDownload PDF (932K) -

JOURNAL FREE ACCESSThis paper deals with the bioluminescence of Cypridina hilgendofii as a teaching material in upper secondary school biology education. In the experiments of the bioluminescence using C.hilgendofii, usually luciferin is extracted with hot water from the dried material to inactivate luciferase. However, in the present study it was found that the luminescence activity of luciferin was extremely decreased by heating. In fact, luciferin extracts which were prepared after the method described in the textbook of biology showed only weak luminescence on mixing luciferase solution. In order to obtain active luciferin extracts some attempts were made using various organic solvents. As a result, extraction with methanol from the dried powder of material was found to be most effective for preparing luciferin. On the basis of the results obtained, the authors presented a typical experiment system for the study of luciferin-luciferase reaction. In the experiment students will be able to observe strong bioluminescence in a test tube and examine the reaction being catalysed by the enzyme luciferase.View full abstractDownload PDF (448K) -

JOURNAL FREE ACCESSIt was in the latter half of 19th century that science began to be introduced into school education in Britain. There was, however, a strong tendency to neglect science as not having the intellectual value. Therefore, it took a good deal of effort for a lot of people to have it accepted as a school subject. Among those, H.Spencer, T.Huxley, H.E.Armstrong played an important role, and especially the work of Armstrong is worthy of notice. This article compares the views on science education by Spedcer and Huxley with the view by Armstrong and clarifies the role which Armstrong's view played. The greatest contribution by Armstrong was to bring both the modern education, established by Rousseau and Pestalozzi, which was based on self-activities by children and the modern scientific method based on the experimental research in the laboratory into the unified form of 'Laboratory Teaching' and to establish the contemporary structure of science teaching in Britain.View full abstractDownload PDF (845K) -
