摘要：

伴随着信息化技术的发展及不可抗力因素的影响等，传统的课堂教学模式已不能满足分析化学的现代化教学。微课是一种新兴的、依托于互联网的优良数字化教学资源。本文以分析化学滴定分析中的滴定突跃为主题，阐述了微课的设计、构思、内容和形式等，展示了微课在分析化学教学中的应用，为传统教学提供了新思路。

关键词: 分析化学, 微课构建, 滴定突跃

Abstract:

With the development of the internet technologies as well as the influence of force majeure factors, the traditional classroom teaching can no longer meet the needs of modern teaching of analytical chemistry. Micro-lecture is a newly rising and online-based premium digital teaching resource. This paper takes titration jump as the representative subject in analytical chemistry course, and illustrates the construction, contents, and exhibition of the micro-lecture. The application of online micro-lecture in the teaching of analytical chemistry provides a novel idea for traditional classroom teaching.

Key words: Analytical chemistry, Micro-lecture construction, Titration jump
