在自然科学发展的同时,建立了各部门知识如数学、化学、物理、生物学等之间的密切联系。显然,这种联系也应反映在普通中学各门学科基本知识的教学上。这种联系将促进学生在普通知识与综合技术上获得发展。中学生物课中一系列的问题如植物的无机养料,光合作用,新陈代谢等,在化学教学过程中获得了进一步的发展与确定。化学在现代农业中获得如此巨大的实际应用,致使在化学与生物学教学中建立联系一事,对综合技术教育说来,具有重大意义。本文叙述作者对这两门课程建立联系的经验。它 At the same time of the development of the natural sciences, a close connection was established between knowledge of various departments such as mathematics, chemistry, physics and biology. Obviously, this connection should also be reflected in the teaching of the basic knowledge of all subjects in ordinary secondary schools. This connection will facilitate students’ development in general knowledge and in general techniques. A series of problems in middle school biology class, such as the inorganic nutrients of plants, photosynthesis, metabolism, etc., have been further developed and determined in chemistry teaching. The enormous practical application of chemistry in modern agriculture has led to the establishment of links in chemistry and biology teaching, which is of great significance to comprehensive technical education. This article describes the author’s experience in establishing contact between these two courses. it
