| The high school chemistry curriculum standards clearly require that chemistry education and teaching must focus on the cultivation of core chemical literacy.Adapting to this requirement,chemistry classroom teaching should practice the principle of teacher led and student centered,and encourage the use of diverse classroom teaching models.The core of exploration and improvement of classroom teaching mode is to follow the basic content and requirements of cultivating chemical core literacy,take chemical knowledge as the carrier,and implement the cultivation of core literacy in the process of chemical classroom teaching activities.This study integrates core literacy into the design of teaching activity sheets.Through the basic process of activity sheet guidance mode scenario creation,autonomous learning,cooperative exploration,display and communication,evaluation and improvement,and self improvement,it achieves and completes the penetration of core literacy in teaching,achieving the goal of improving students’ learning ability and cultivating students’ core chemistry literacy.This study is divided into three parts.1.The research background and research status of this subject are understood by using the literature method,and the concepts of activity single guide model and chemical core literacy are sorted out.At the same time,the relevant analysis of the two shows that activity single guide model is conducive to the cultivation of core literacy.2.Through questionnaire survey of all students in Grade one and interview of chemistry teachers in grade one,this paper studies the transformation of traditional teaching methods and learning methods and the improvement of students’ quality and ability based on the activity guided learning model.Based on the analysis of chemistry curriculum standards,teaching materials and learning situation,the teaching objectives oriented by core literacy were established,and the teaching design based on activity guided learning mode was completed.Based on the teaching cases of "Ferric Salt and ferrite" and "Nitrogen and Nitrogen Oxides",the design process and ideas of implementing core literacy in the design of activity list are analyzed,and relevant teaching strategies are used to apply activity list into teaching practice.3.Conduct teaching practice and analyze the research results to draw basic conclusions.The experimental teaching method is used to select two classes with the same situation to carry out practical teaching.The experimental class adopts the activity single guidance mode for teaching,while the control class adopts the traditional method for teaching.After the practice,the implementation effectiveness of the activity single guidance model was analyzed and evaluated through performance testing in the experimental and control classes,student questionnaires,and interviews with teachers and students.The practice results show that both teachers’ teaching and students’ learning have given positive feedback to the activity single guidance model,achieving significant teaching and learning effects.The activity single guidance model has a significant promoting effect on mobilizing students’ enthusiasm for learning,improving their academic performance,and improving their academic literacy and learning ability.At the same time,the problems faced in the process of research and practice were considered and further prospects were made. |
