给树贴应变片—交叉学科实验教学实践

Application of Strain Gauges to Trees-Experimental Teaching Practice of Cross-disciplinary Subjects

学科交叉现已成为普遍现象。本文以树木中"生长应变"的测量实验为例,讨论教师应如何开展交叉学科的实验教学。首先,在教学时应打破以往的课程界限,利用一切可能的机会让学生接触交叉学科新概念;其次,可利用正在进行的科研项目,为学生提供学习和实践机会;再次,通过学生参与,可促进科研项目的研究。在教学过程中,应注重引出问题,引发思考,激发学生创造力,从而能够有建设性地解决问题。

Subject crossing has become a common phenomenon.In this paper,＂growth strain＂measurement experiment in trees is taking as an example,and how teachers should carry out the experimental teaching of inter-discipline is discussed.First of all,the former curriculum boundaries should be broken in teaching.Advantage of all possible opportunities to expose students to new concepts of inter-discipline should be taken;Second,make use of ongoing scientific research projects to provide students with opportunities to learn and practice.Through student participation,the research of scientific research projects can also be promoted. In the process of teaching,attention should be paid to eliciting problems and thinking,so as to stimulate students＇creativity and solve problems constructively.
