HPS模式在中学化学教学中的融合——以“电解质”的教学设计为例

The Fusion of HPS Model in Chemistry Teaching in Middle School——Taking the Instructional Design of“Electrolyte”as an Example

以“电解质”概念的教学为例,引入法拉第、阿伦尼乌斯等科学家的探索故事,有效将HPS教学模式融入课堂,带领学生体会化学史路径,使学生在学习中体验化学的奇妙,树立正确的科学观。通过三个环节逐步让学生认识电解质,引导学生自发总结出电解质的概念,从而深度理解这一抽象概念,培养归纳总结的能力,提高化学学科核心素养。

Taking the teaching of the concept of electrolyte as an example,this paper introduces the exploration stories of Faraday,Arrhenius and other scientists,effectively integrates the HPS teaching model into the classroom,leads students to experience the path of chemistry history,and enables students to experience the wonder of chemistry in learning and establish a correct view of science.Through the three steps,students are gradually made aware of electrolytes,guided to spontaneously summarize the concept of dielectric,so as to deeply understand this abstract concept,cultivate the ability of induction and summary,and improve the core quality of chemistry.
