无机化学实验课增加提问环节的探索

An Investigation of Question-and-answer Model in Inorganic Chemistry Experiment

为了强化学生的问题意识培养,提高学生的口头与书面表达能力,我们在无机化学实验课中增加了提问环节,包括三个层面:一是教师提问式的讲解,二是教师提问、学生回答,三是学生提出问题。教师讲授实验时,不断设问,不需学生回答,只是引起学生思考,让学生跟住教师的思路,学会分析问题、抓住重点、掌握本质。教师提问和学生回答的方式能够加强学生对实验细节与关键点的掌握。教学中鼓励学生主动回答问题,尤其鼓励学生提出问题。

In order to strengthen students＇ problem consciousness,to improve their ability of oral and written expression,question-and-answer model is introduced into inorganic chemistry experiment course.This model includes three aspects,the first one is that teacher explains the chemical phenomena by question-asking;the second one is students are required to answer questions provided by the teacher;and the last one is to encourage students to ask questions based on their observation.Asking questions without answering by students will inspire them to think deeply;to keep up with teacher＇s train of thought.This will also make them learn how to analyze,how to grasp the spirit,and how to understand the essence of chemical phenomena.The way of asking-and-answering will deepen students＇ understanding of the details and keys of the experiment.Answering questions actively is encouraged,putting forward questions is particularly done.
