目前,我国中、小学生物教学中,实验课是一个很薄弱的环节。其原因之一是缺少适宜的、多用途的生物学实验材料。国内如此,日本也是这样。在日本东京都中等学校生物教育研究会之下,设立了“家蚕教材化研究委员会”,并于1970年出版了“以家蚕为实验材料的新生物实验”一书。该书根据小学、中学及中等专业学校生物学教育的总则,编写了各类型的实验指 At present, experimental teaching in primary and secondary school biology teaching in China is a very weak link. One of the reasons is the lack of suitable, versatile biological experimental materials. The same is true in Japan. Under the Tokyo Metropolitan Secondary School Biology Education Research Society, a “Silkworm Textbook Research Committee” was established and in 1970 a book entitled “The New Biology Experiment with Silkworms as Experimental Materials” was published. The book according to the general principles of biology education in primary, secondary and secondary vocational schools, the preparation of various types of experimental finger
