素养为本的线上虚拟化学实验教学——以《探究补铁剂的变质情况》为例

Literacy-riented online virtual chemical experiment teaching——Take“exploring the deterioration of iron supplements”as an example

“素养为本”的教学强调真实问题情境的创设、实验教学功能的挖掘。疫情期间,受制于线上教学的客观条件,化学教师难以实现“素养为本”的教学。以“探究补铁剂的变质情况”为主题,围绕Fe^(2+)和Fe^(3+)之间的转化与检验,向化学教师介绍如何基于NOBOOK虚拟实验室进行虚拟化学实验教学,以期实现“素养为本”的线上教学。

Literacy-oriented teaching puts emphasis on the set-up of real problem situations and the exploration of functions of experiment teaching.During the pandemic of Covid-19,literacy-oriented chemical teaching is confined to these objective limitations of online teaching.This passage is based on,revolving around the transformation and verification between Fe^(3+)and Fe^(2+),aiming to introduce the procedures of virtual chemical experiment teaching to chemical teachers in the NOBOOK virtual laboratory,which is expected to accomplish the literacy-oriented online teaching.
