| Research Abstract |
The purpose of the present research is to select some suitable living materials for teaching a variety of reproductive strategies of plants to primary and secondary school students and to develop some appropriate methods for teaching them by means of trials in some schools. Our results are as follows.
(1) Both the terms and the contents of laboratory exercises relating to reproduction and propagation and the living materials used in teaching these topics, with reference to plants, were surveyed in the present and previous science textbooks for the primary and secondary levels. After that, these living materials were examined to see how suitable they are for teaching these topics.
(2) Some plants which seem to be useful for the observation of sexual or asexual reproduction and for studying the propagation of plants in the primary and secondary levels were chosen and examined further to find the best experimental conditions for observing these phenomena.
(3) A text for laboratory exercises on the reproduction and propagation of plants using these selected plants was made. A teacher's manual for these laboratory exercises was also prepared.
(4) Some typical phenomena of sexual and asexual reproduction and a variety of reproductive strategies of plants were recorded as audio-visual materials which can help students understand reproduction and propagation of plants.
(5) Laboratory exercises and audio-visual materials were tested at the science classes in some elementary and junior high school and the responses of pupils, students and teachers to these exercises, teaching materials and teaching methods were examined.
