摘　　要：循证理论注重决策的有证可循,可以为教师的教学提供新的思路,强调教学决策的证据支撑。厘清循证理论指导下化学探究性实验教学中的四大证据要素及其关系,结合化学探究性实验的特征,探讨了在循证理论指导下化学探究性实验的教学模式。以“乙烯与溴的加成反应”探究实验教学为例,阐述教学模式的具体应用,即教师合理整合各类证据,明确教学目标,体现探究规律,充分预设课堂诊断性证据,设计可动态调整的教学方案。学生自主设置实验探究方案,推理事实现象,优化实验设计,内化实验探究规律。Evidence-based theory focuses on evidence-based decision-making,which can provide new ideas for teachers’teaching and emphasize the evidence support of teaching decision-making.This paper clarifies the four evidence elements and their relations in chemical inquiry experiment teaching under the guidance of evidence-based theory,and discusses the teaching mode of chemical inquiry experiment under the guidance of evidence-based theory combined with the characteristics of chemical inquiry experiment.Taking the inquiry experimental teaching of“addition reaction of ethylene with bromine”as an example,this paper expounds the specific application of the teaching mode,that is,teachers reasonably integrate all kinds of evidence,clarify the teaching objectives,reflect the inquiry law,fully preset the classroom diagnostic evidence,and design the dynamically adjustable teaching scheme.Students independently set up experimental exploration schemes,infer facts and phenomena,optimize experimental design,and internalize experimental exploration laws.
