Desing Of Chemical Skill Knowledge Problem Sheet And Its Optimization Strategy Teaching Reserch

Chemical skill knowledge is an important part of chemical knowledge content,and it is the basis for students to master and apply chemistry.If students cannot expertly use chemical terms and do not have the necessary chemistry experiment skills and chemistry calculation skills,it will inevitably cause difficulties in chemistry learning and affect the effectiveness of solving chemistry problems.Problem solving is the basic way for students to learn knowledge and explore science.Guided by the psychological mechanism of problem solving and skill knowledge learning,and based on the theory of the nature of skill knowledge,this paper takes the problem sheet as a model of problem solving and combines it with the learning of chemical skill knowledge to build a model of skill knowledge problem sheet.On the basis of theoretical research,this model is applied to practice.In practice,in addition to using the problem form for teaching,students are guided to use the problem form to review knowledge and solve problems.And will issue the form teaching mode compared with the traditional teaching mode,using the interview method and case method to the research object of knowledge construction after implementation of the teaching practice research and analysis,from the research conclusion shows the problem form teaching mode for students to build skills,knowledge and problem solving has certain help,and the student to knowledge construction is more stable,effective and more comprehensive and in-depth knowledge.On the basis of empirical research,the author puts forward corresponding optimization strategies to provide reference for teaching.It can be seen from the literature that the research on problem form model in the problem solving field is relatively new,while the research on the teaching of chemical skill knowledge is more rarely reported.In this paper,the author organically combines the problem form with the teaching of skill knowledge,establishes the problem form model of the content of skill knowledge,and probes into the feasibility of the problem form teaching and the effective way to solve students' problems.To provide students with new methods of knowledge learning and problem solving,it helps students clarifythe conceptual elements,fill in the thinking holes,strengthen the conceptual logic,so as to deepen the levels of conceptual connotation,improve the construction of knowledge system,and improve students' problem solving ability.
