基于多元外在表征理论的酸碱中和滴定概念教学设计

Teaching Design of Acid-Base Neutralization Titration Based on Theory of MERs

在多元外在表征教学理论的基础上，提出了酸碱中和滴定的教学设计，主要包括创设酸碱中和滴定实验情境、引入酸碱中和滴定概念与原理、介绍滴定管、选择指示剂、演示实验、使用Netlogo解释酸碱中和滴定等内容。研究结果表明该教学设计能帮助高职生更好地理解“酸碱中和滴定”知识。

This paper put forward the teaching design of acid-base neutralization titration based on the theory of MERs, setting experimental situation for acid-base neutralization titration, introducing the concept and principle of acid-base neutralization titration and burettes, selectingindicator, demonstrating the experiment and explaining acid-base neutralization titration with NetLogo. The results showed that it could help higher vocational students better understand the knowledge of acid-base neutralization titration.
