我们为了使学生对书本知识有更深刻更彻底的了解,我校大力提倡直观教学,发动师生创造直观教具。我们在课余组织了以学生为成员的“生物学社”。学生通过自己的脑子和手制造出来许多件动植物及生理卫生的标本模型。同学们在制做过程中不但提高了自己的科学知识,而且培养了钻研生物学的浓厚兴趣,从而也巩固了课堂教学。在这样的基础上为了进一步使学生对生物发展过程认识的更清楚,必须做生物发育过程的实验,必须随时培养种子、培养细菌、培养动物胚胎。不过要做这些实验没有保温箱是做不到的,到市
In order to make students have a deeper and thorough understanding of the book knowledge, our school vigorously promotes visual teaching and mobilizes teachers and students to create visual aids. We organized student-affiliated “Biology Society” after school. Students through their own brain and hand to create a number of animal and plant specimens and physical health model. Students in the process of making not only improve their own scientific knowledge, but also cultivate a strong interest in studying biology, which also consolidated classroom teaching. On this basis, in order to further clarify the students’ understanding of the process of biological development, experiments on the process of biological development must be done. At any time, it is necessary to cultivate seeds, cultivate bacteria and culture animal embryos. However, there is no incubator to do these experiments can not do, to the city
