我校在苏联专家谢孔同志和北京师大生物系教学法组同志的指导之下,自建立生物实验园地以来,就根据苏联学校的经验,努力改进我们的教学工作。谢孔专家教导我们,在中学生物实验园地上可以进行下列各种类型的工作:(1)上课;(2)参观;(3)实习;(4)试验研究工作;(5)长期的生物学观察;(6)米丘林生物学家小组的工作。现在以“冬小麦”这一课为例,介绍一下我们是怎样在生物实验园地上讲课的。一.准备工作根据教学大纲(草案)的精神,在讲“栽培植物”一章时,应广泛地利用实验园地,着重贯彻理论与实际一致的原则。我们在开学后即着手准备这章的教学,其中有关“冬小麦”一节的准备工作,做了下列几项: 1.了解到当地农民播种冬小麦的情况是:用耧播种,行距一般在55厘米以上,播种量是每亩12—15斤,品种以杂种较多;有的农业生产合作社播种优良品种“七二麦”,有的由农场用双轮双铧犂和马拉播种
Under the guidance of Comrade Hsieh and Soviet Union expert Comrade Xie Kong of Beijing Normal University Department of Biology, we have tried our best to improve our teaching work based on the experiences of Soviet schools since the establishment of a biological experimental field. Dr. Xie Kong taught us that the following types of work can be carried out on the Bio-Experimental Park in middle school: (1) class; (2) visit; (3) internship; (4) experimental research; (5) Observation; (6) The work of the Michurin Biologist team. Now take the lesson “Winter Wheat” as an example to explain how we lecture in the biological experiment field. I. Preparation According to the spirit of the Syllabus (Draft), when it comes to the chapter on “Planting Plants,” we should make extensive use of experimental parks and focus on implementing the principle of unanimity of theory and practice. We started the teaching of this chapter immediately after the start of the school. Among them, the preparations for the “winter wheat” section were as follows: 1. It is understood that the situation of local farmers sowing winter wheat is: Above, seeding rate is 12-15 kg per acre, more varieties to hybrids; some agricultural cooperatives sowing fine varieties “Qiermai”, and some by the farm with double round plow and Mara sowing
