高等學校 生物 實驗實習敎材의 開發硏究 Ⅰ = Studies on the Development of Laboratory Teaching Materials for High School Biological Course Ⅰ

다국어 초록 (Multilingual Abstract)

Teaching materials available for the effective performance of laboratory experimental work in high school biology were developed, laying emphasis on the following items : environmental pollution and natural conservations, biological concepts that the degree of difficulty is high, applications of teaching materials which are developed in foreign conturies, productions of teaching materials and models.
The measuring methods of size of micrography without micrometer or with a
hand-made glass micrometer were developed.
By observing the morphological characters of liverwort, the methods of telling its sex, distingshing its life cycle into sexual reproduction and asexual reproduction, and comparing its life cycle with those of other plants were presented.
By observing the morphological characters of moss, the methods of telling its sex and comparing its life cycle with those of liverwork, ferns and flowering plants were presented.
A convenient observing method of cartilaginous and bony tissues in animals was
developed using the easily available material in our surrounding The observing method of extension and contraction of chromatophores induced by environmental changes on freshwater fishes was developed.
The methods of sorting and identifying the higher plants by observing their leaves and flowers were presented.
The improved analytical method of plant community structure was presented by using the artificial plant community within laboratory.
The assesing method of harmful effects on plant tissues by sulfur dioxide was
improved.
