Research On The Application Of Geography Documentary In Geographical Problem-based Teaching In Senior Middle Schools

With the comprehensive advancement of the new geography curriculum reform,the new geography curriculum standard clearly states that it is necessary to continuously innovate the methods of cultivating students’ core literacy in geography.Therefore,the importance of strengthening the integration of information technology and curriculum implementation and conducting problem-based teaching development has become increasingly prominent.Based on the problem-based teaching method of geography,it is a useful attempt to explore geography documentary for cultivating students’ core literacy of geography and constructing new and efficient classroom methods.Problem-based teaching takes problems as clues,creates real problem situations,finds problems around the situation,analyzes and solves problems,and finally achieves the teaching goal.This thesis takes the application of geographic documentaries in high school geography problem-based teaching as the research object.It uses the scenes shown in geographic documentaries to create situations and raise questions,and analyzes the problems by describing phenomena and explaining principles.The measures provided are used to solve the problems.Questions,and put forward a corresponding summary evaluation of the part of the summary and sublimation.This research takes learning motivation theory and constructivism theory as the theoretical basis of this research,using research methods such as questionnaires and case methods to collect,classify,build a resource bank and the application of geographic documentaries in high school geography problem-based teaching The status quo was studied.Through questionnaire surveys and interviews,it is concluded that the application of geographic documentaries to problem-based teaching mainly has problems such as limited class time,time-consuming documentary resource selection,difficulty in problem design,and poor concentration of students.Based on this,this research focuses on the methods of collecting geographic documentaries and building a resource library.Collect geography documentaries through the methods of "finding points by surface","finding points by point method" and "multiple approaches",sort them according to different topics,and use the new and old geography textbooks published by the People’s Education as the baseline to construct The geography documentary resource library.Finally,a model case of the application of geographic documentary to the teaching of geographic problems is constructed,and the teaching content of the section "Desertification Prevention and Control" constructed is presented as a case.This thesis applies geography documentaries to geography problem-based teaching,creates problem situations through geography documentaries,and sets up problem chain integration content,which is conducive to cultivating students’ core geography literacy and problem awareness through contextual learning.The resource library and design of geography documentaries are built The case provides an example for geography teachers in the combination of geography documentary and geography problem-based teaching.
