| Geography has the characteristics of comprehensiveness and regionality,and has the nature of both natural and social sciences.The " core literacy of Chinese students ’development " proposes to take " all-round development of people " as the core,including "cultural foundation,independent development,and social participation." The " International Charter for Geography Education 2016 " proposes that geography learning should enable students to solve the problems and challenges of the current era from a geographical perspective.In recent years,the practice of combining project-based teaching with basic education has gradually increased,but there are not many cases in the current high school geography teaching.Interdisciplinary project-based teaching is an effective way to break the boundaries of disciplines and promote the all-round development of students.In order to cultivate students to become fully developed people and promote students ’ ability to solve practical problems,it is a trend of geography education to carry out interdisciplinary projectbased teaching in high school geography teaching.This paper takes interdisciplinary project-based teaching as the research object,adopts literature research method,case analysis method and action research method,and constructs the theoretical model of research based on constructivism theory,multiple intelligence theory,pragmatism theory and developmental teaching theory.This paper expounds the concept of project-based teaching and interdisciplinary subject project-based teaching,demonstrates the feasibility of high school geography project-based teaching based on interdisciplinary subject,puts forward the principle and overall framework of high school geography project-based teaching based on interdisciplinary subject,and carries out the demonstration and improvement of high school geography project-based teaching based on interdisciplinary subject.The conclusions of this paper are as follows :(1)From the perspective of the compatibility of curriculum concepts,consistent training goals,and common problem nature,the close relationship between interdisciplinary themes and project-based learning was analyzed,and the feasibility of project-based teaching of high school geography based on interdisciplinary themes was demonstrated.(2)The principle of project-based teaching of high school geography based on interdisciplinary themes is proposed,and the overall framework of interdisciplinary projectbased teaching is constructed,which is divided into three stages: "project development stage-project implementation stage-project summary stage",and six links of "design project name-design-driven problems-student cooperative inquiry-production of project results-display of project results-evaluation summary and reflection",and put forward specific steps in different links.(3)Taking the compulsory high school geography course 1 "Vegetation" and optional compulsory 2 "" The Belt and Road " and international cooperation" as teaching cases,carry out project-based teaching empirical research on interdisciplinary themes,and evaluate the teaching effect through project implementation process evaluation and paper-and-pencil test.Studies have shown that project-based teaching on interdisciplinary themes can stimulate students’ interest in learning geography,facilitate and implement and create learning methods that cultivate core competencies,and improve students’ comprehensive thinking ability and interdisciplinary learning ability. |
