Research On Deep Learning Of Chemistry In High School Based On Theme Teaching

"Ordinary high school chemistry curriculum standard(2017 edition)" advocates the creation of real problem situations and proposes to change students’ learning methods and implement the cultivation of students’ core literacy.Deep learning,as a new teaching concept to tap learners’ potential,improve students’ advanced thinking and promote ability development,is one of the important ways to cultivate students’ core literacy.Based on the characteristics of chemistry and the idea of thematic teaching,this paper puts forward the use of thematic teaching to promote students’ chemical deep learning,and tries to study from the perspective of the integration of thematic teaching and chemical deep learning,in order to promote the transformation of students’ learning methods,and then implement the cultivation of students’ core literacy.In this study,first of all,through literature research method to sort out the domestic and foreign research on topic-based teaching and deep learning,the existing research has been effectively integrated to determine the core concepts and theoretical basis.After that,the current situation of subject-based teaching and deep learning in high school chemistry is investigated and analyzed through the investigation method.According to the survey results,the ability level of students is determined.Taking this as the starting point,combined with the general route of deep learning,this paper puts forward the route of deep learning based on topic teaching.At the same time,the specific route is expounded,and the teaching methods that can help realize this route are proposed.Three teaching cases of "sulfur dioxide in wine","acid rain" and "chlorine in swimming pool" were selected.Two parallel classes were selected for teaching practice in a middle school in Linxia.The experimental class was taught by deep learning route based on topic-based teaching,and the control class was taught by traditional way.After practice,the feasibility and effect of the study were obtained by questionnaire survey and classroom observation combined with paper and pencil test.The results show that the deep learning based on topic-based teaching has a certain effect on promoting the transformation of students’ learning methods.After the deep learning based on topic-based teaching,students’ interest in chemical learning,knowledge construction and processing ability,criticism and questioning ability,metacognitive capability,reflection and summary ability are improved,and it is also helpful to improve the overall quality of students.It shows that the deep learning based on topic-based teaching proposed in this study has certain practical value in high school chemistry teaching.
