项目摘要

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.

本研究的目的是选择适合中小学生植物繁殖策略教学的活体材料，并在部分学校进行实验，探索适合中小学生植物繁殖策略教学的方法。我们的结果如下。(1)有关生殖和繁殖的实验练习的术语和内容，以及在这些主题的教学中使用的生物材料（涉及植物），已在目前和以前的小学和中学科学教科书中进行了调查。之后，这些生活材料进行了检查，看看他们是否适合这些主题的教学。(2)选择了一些似乎对观察有性或无性繁殖以及研究植物初级和次级繁殖有用的植物，并进一步进行了研究，以找到观察这些现象的最佳实验条件。(3)使用这些选定的植物进行植物繁殖和繁殖的实验室练习的文本。还为这些实验室练习编写了教师手册。(4)记录了植物有性繁殖和无性繁殖的一些典型现象以及植物的各种繁殖策略，作为视听材料，帮助学生了解植物的繁殖和繁殖。(5)在一些小学和初中的科学课上测试了实验练习和视听材料，并检查了学生、学生和教师对这些练习、教材和教学方法的反应。
