基于5E模式的化学探究性教学设计——以“茶垢清洁剂成分探究”为例

Design of Inquiry Teaching of Chemistry Based on the 5E Model:Take“Exploration of Ingredients of Tea Scale Cleaner”as an Example

基于5E教学模式,开展了“茶垢清洁剂成分探究”的教学设计。通过提出问题、作出猜想、设计方案、实验探究、归纳总结等步骤,利用手持技术数字化实验,设计了以茶垢清洁剂为主题的中学化学探究性教学,将5E教学模式在教学中开展了实践。

Based on the 5E teaching mode,the teaching design of“exploration of ingredients of tea scale cleaner”was carried out.Through the steps such as raising a question,guessing,designing a scheme,experimental inquiry,and summarization,by using digital experiment of handheld technology,the inquiry teaching of chemistry in middle school was designed with the theme of tea scale cleaner and the 5E teaching mode was applied in teaching.
