For high school students, evolution of animal behavior seems to be the most difficult concept to understand due to unavailable examples off ered by text books. In the present study, we developed teaching materials for the evolution of animal behavior and proposed the methodology.　In the Japanese sulfur butterfl y Colias erate, polyandrous alba females are the dominant morph in the female population, though mated females do not easily re-accept males courting.　The wings of mated alba captured in the field were closed by glue, and they were tethered in the grassland where males were searching for mates.　We observed 1,830 entries of males into the imaginary hemisphere of 1 m radius around each female.　A half of the males noticed and visited our females.　Due to the closed wings, every female was unable to show the mate refusal posture, so the males continued their courtship behavior.　However, the duration of hovering around the females was short in the morning, and most males left the females without touching them.　Because newly emerged females promptly accept copulation with males in the early morning, males might prefer virgin females to mated ones.　On the other hand, males that visited the females around noon prolonged the duration of hovering and tried to copulate persistently.　The adaptive significance on the behavioral sequence was easily observed due to the closing femalesʼ wings.　Manipulation of the butterfl y wings in the field observation was discussed in the viewpoint of the teaching materials for high school education on evolutionary biology.

It is important for students to study the skeletal structure for understanding morphology, function, classification and development of vertebrate.　However, almost all junior high schools have few skeletal specimens and there are few guides to make them for junior high school teachers.　In this study, I tried to show the effective methods to make the skeletal specimens.　Animals were classified into three groups of “small” (less than 500 g body weight), “medium” (between 500 g and 1.0 kg) and “large” (more than 1.0 kg) for convenience.　The protease method (PM) and the detergent for pipe drainage method (DPDM) were applied to each group.　Although PM was able to remove soft tissues within a short period (2-9 hours) in “large”, the bones tended to be deteriorated.　It should be noted that the preparation of specimens with PM was difficult in “small”. However, ultimately, soft tissue could not be completely removed from “small” and “large” with DPDM.　In consequence, it was suggested that PM was useful for “large”, whereas DPDM was suitable for “small”.　For “medium”, the parallel method, in which the vertebral and extremities parts were treated with PM, and the costal and foot parts were treated with DPDM, was suitable.

本研究の目的は，①中学校理科教科書に掲載されている身近な計16種類の野草の写真を提示しながら，野草に対する小中学校教員志望学生の関わり（“実際に見たことがあるか”や“触ったことがあるか”）について調査すること，及び②中学校理科教科書中に掲載されている身近な野草の名を正確に記すことができるか否かを明らかにすることにある．得られた知見は，以下の４点である．１）計16種類のうち５種類の野草について，見た経験を有する学生は50％未満であったこと，２）同じく，計16種類のうち９種類の野草について，触った経験があると回答した学生は50％未満であったこと，３）計16種類の野草の名を，すべて正確に記すことができた学生は皆無であったこと，及び４）計16種類のうち５種類の野草について，その名を記すことができた学生は皆無であったこと．さらに，上記１）～４）の問題点を改善するための方策についても言及した．

It is thought that the experiments on human genome/gene analysis with PCR, elecrophoresis and so on, for educational purposes using studentsʼ own genome in schools are good for attracting their interests, studying about the essence of human genome, and thinking about the concerned problem themselves.　But these kinds of experiments need expensive reagents and instruments, the teachersʼ deep knowledge and experience of molecular biology experiments.　So it is not easy to become popular in schools.　On the other hand, there are many teachers who want to do these experiments but feel uneasy about bioethics and the control of personal genetic information because there are no guidelines of the human genome/gene analysis for education.　To make a suitable environment where teachers can do the experiments more easily, we investigated what was needed to it.　We concluded that setting guidelines similar to DNA transformation experiments is needed for education.　Therefore, we propose human genome/gene analysis guidelines for education, especially at high school, with consideration of bioethical issues, social issues, including control of genomic information, and experimental consideration for teachers.
