The Problem Situation Creation Of High School Geography Class Based On Comprehensive Thinking Of Geography

Geography core accomplishment is the necessary geography accomplishment extracted from the core concept of geography,which embodies the educational value of geography and is an important part of geography curriculum reform.As one of the core qualities of geography,comprehensive thinking is the basic thought and method reflecting the comprehensive characteristics of geography,which plays an important role in people's comprehensive,systematic and dialectical understanding of the geographical environment and its relationship with human activities.The cultivation of comprehensive thinking is placed in the actual problem situation,and the practical background of knowledge generation is revealed through the interaction between the subject and the environment,so that students can improve the comprehensive thinking in the process of solving the situation problem,and be able to transfer and apply it in the future study and life.Starting from reading literature,concludes the background and significance of the research,the research status,the research ideas and methods,defines the relevant concepts,and determines the theoretical support.The third part investigates the current situation of front-line geography teachers through the application of the classroom observation scale and interviews,and finds that teachers still have some problems in the classroom problem situation creation of cultivating students' comprehensive thinking.Such as:teachers have low awareness of cultivating students' comprehensive thinking;There are few ways to create problem situation,and the dimension of comprehensive thinking cannot be fully reflected in the situation creation;The problem situation creation lacks completeness and interest;Do not pay attention to guide students to ask questions from the perspective of comprehensive thinking;The presentation of problems does not reflect the thinking process and hierarchy of comprehensive thinking;The problem expression lacks the characteristic of comprehensive thinking and so on.The fourth part points out the strategies of problem situation creation from the two aspects of situation creation and problem design: Taking compulsory course 1 as an example,this paper analyzes the content of teaching material which is beneficial to the cultivation of comprehensive thinking and its corresponding cultivation dimensions and levels;According to the dimension of comprehensive thinking which is suitable to be cultivated in each way,the method of problem situation creation is given from image system,case,experiment,multimedia,etc;To guide students to raise questions from the perspective of comprehensive thinking by constructing a model of cognition;The presentation of problem chain reflects the thinking process of each dimension and the level of each dimension of comprehensive thinking;The key words,cognitive operations,learning content and other components of the problem are described around the characteristics of comprehensive thinking.Taking the water cycle in nature as an example,the problem situation is created to demonstrate the applicability of the proposed strategies.The fifth part summarizes the conclusions,shortcomings and prospects of this paper.The conclusions are as follows: the necessary classroom observation scale is constructed,the existing problems of problem situation creation based on comprehensive thinking in classroom teaching are found,and the strategies of problem situation creation are proposed.
