Abstract:University physics demonstration experiment teaching plays an important role in college physics teaching, and there are many kinds of demonstration experiment teaching model,so how to select the appropriate teaching model to let the demonstration experiment achieve better teaching results,we should take full account of the demonstration instruments’features,the levels of students and other factors.This paper combined with years of teaching experience, on the basis of combining variety of teaching models,extends the demonstration experiment to students’activities and strengthens the teaching effect of demonstration experiment.
Key Words:Demonstration Experiment;Teaching Mode;Teaching Effect
物理學本質(zhì)是一門實驗科學。實驗使得理論直觀形象、有據(jù)可依;理論使得實驗科學嚴謹、有理可循。所以大學物理教學離不開實驗教學,而演示實驗教學更是大學物理教學過程中不可缺少的一環(huán)[1-2]。演示實驗以其原理易懂、操作簡單、現(xiàn)象生動,深受學生的歡迎。但由于大學物理課程內(nèi)容較多而學時較少使得一些教學工作者對演示實驗重視度不夠,再加上學校經(jīng)費有限等因素往往使演示資源沒有充分利用。
1 演示實驗的特點
物理演示實驗的目的就是把要研究的物理現(xiàn)象清晰地展示給學生,引導(dǎo)學生觀察思考和理解物理規(guī)律[3]。通過觀察物理現(xiàn)象,思考物理規(guī)律,學生得出的認知是符合人類的認知規(guī)律的,這種教學勢必更加科學。演示實驗教學要么隸屬于大學物理教學,要么獨立成課,無論選用哪種教學模式都應(yīng)充分考慮到演示實驗的特點。
用于演示實驗的儀器,結(jié)構(gòu)簡單、容易操作,對操作者的實驗水平要求不高。……
