基于翻转课堂的分析化学实验教学改革实践

Reform and Practice of Analytical Chemistry Experiment TeachingBased on FlippedClassroom

分析化学实验是化学学科的基础课程之一,但在传统的实验教学中,无论是学生方面、课程方面还是考核方面都存在着诸多问题。本文分析了目前分析化学实验课程的现状,并以“硫代硫酸钠标准溶液的配制和标定”为例,将翻转课堂的教学理念应用到本实验的教学改革中,从课前、课上和课后三个方面进行了改革设计。通过本次教学实践探索,增加了学生对实验课程的学习兴趣,也提高了学生的语言表达、分析问题及实际动手能力。

Analytical chemistry experiment is one of the basic courses of chemistry,but in the traditional experiment teaching,there are many problems in terms of students,courses and assessment.This paper analyzes the current status of analytical chemistry experimental courses,and takes"preparation and calibration of sodium thiosulfate standard solution"as an example to apply the teaching concept of flipped classroom to the teaching reform of this experiment,and carries out reform design from three aspects:before,during and after class.Through this teaching practice exploration,the students'interest in the experimental course is increased,and their language expression,problem analysis and practical ability are also improved.
