Research On The Teaching Design Of The Big Concept Unit Of "Resources, Environment And National Security"

Geography Curriculum Standard for Ordinary Senior High Schools(2017 edition,revised in 2020)emphasizes big ideas,emphasizes transfer teaching,and attaches importance to cultivating students' core accomplishment and real problem solving ability.Geography core literacy calls for the transformation of teaching design,from knowledge point design to knowledge logical structure design,from class hour design to unit design.Through the questionnaire survey,it is found that most front-line teachers encounter difficulties in organizing logic and reorganizing unit contents,and lack theoretical guidance and referable design schemes.The basic education reform attaches great importance to national security education,and the new curriculum standard adds the module of Resources,Environment and National Security,and attaches great importance to the cultivation of the overall national security concept.This paper takes the module of Resources,Environment and National Security as an example,takes the big concept as the starting point,and reconstructs the unit content from the unit logic.The main research process and results are as follows:First of all,the key elements of this module are determined based on the detailed analysis of the course standard and textbook,and the structure and connection of the elements are visually analyzed by using the interpretive structure model method,so as to build a big concept network with clear structure and hierarchy.From this,three big concepts of geography and one big concept of course ideological and political philosophy are extracted.They are "man-land relationship is the unity of opposites","human activities can only be sustainable within the limits allowed by natural environment","harmonious man-land relationship is the guarantee of national security" and "overall national security concept".Second,the comprehensive analysis of the four editions textbook chapters structure and large network of commonness and individuality,the commonness as the basic logic and restructuring of the unit is to construct the unit skeleton,to split reorganization of personality part combined with the specific content,eventually to build "natural resources and national security" and "environmental issues and national security" two interconnected units.Finally,unit reverse design is carried out for the constructed large concept unit.In "phase one" determine unit objectives and big ideas,design basic clues to lead unit,in the "phase 2" design is given priority to with expressive task unit evaluation,including unit final task,popular science video production and homework,news analysis,in the "three stages" according to the unit design objectives and evaluation unit learning activities,and refine the class design,In order to enhance the operability of teaching practice,to provide reference for teachers.Due to the limited theoretical knowledge and lack of teaching experience,the unit and class teaching plan designed in this paper may have some deviation from the actual demand,and there is still room for improvement and improvement.
