Study On Theoretical Knowledge Of High School Chemistry Based On Problem Solving Teaching Model

As the society has come to give more priority to education at school,education goal of subject core quality has been put forward in 2017 new curriculum standard.It is found that students cannot apply theoretical knowledge to solve practical problems,therefore,the author believes that teaching students how to think,how to solve problems,and how to turn the thinking mode of problem solving into the ability of solving problems of students are the problems we need to study and examine at present.In order to improve the comprehensive quality of students,facilitate the subject core quality,improve the study efficiency of students and make a break through in the difficulties and key points in teaching,the author have taken the study on teaching to solve problems at home and abroad as reference to apply the resolution to questions into the teaching of chemical theoretical knowledge under the guidance of high school chemical curriculum standard.Integrated with the characteristics of chemical theoretical knowledge and analysis of psychological mechanism when high school students are learning chemical theoretical knowledge,the author put forward a teaching model in line with the teaching in senior high school in Qinghe Forest Region,to help students to build a theoretical knowledge system.The teaching model focuses on questions,and it is carried out in the order of putting forward,analyzing and solving questions,which allows students to combine their thinking method with scientific approaches in the process of independent learning.Through the communication and cooperation among students and teachers,students can optimize their knowledge structure,thus improving their ability to solve problems.The author chose two classes as samples to make study,in where Science 1 Grade 2 is the control class and Science 2 Grade 2 is the experimental class.In the control class,traditional teaching is carried out,while problem solving teaching is delivered in experimental class.Before practice,the author made an in-depth understanding about the teaching status quo of high school chemical theoretical knowledge through questionnaire survey and interview,which was then taken as the basis for practical study.Through one term of teaching,the results indicated that the scores of experimental class are obviously higher than those of control class,which testified that the teaching method of problem solving is effective and it can accomplish the goal of teaching.Moreover,the author have made certain adjustment to the previous problem solving teaching model,which prioritizes the feature of chemical theoretical knowledge.With the combination of teaching experience in this subject,the author put forward the teaching model in conformity of high school situation,thus enriching the dimension and breadth of this teaching model.The study in senior high school in Qinghe Forest Region provided theoretical guidance to the theoretical knowledge teaching in this region,it will also help to improve the current situation of chemical courses.Thus,it can advance the teaching level of chemistry in this region.
