Research On The Teaching Strategies Of Science Popularization Micro-Video In Developing Geographic Comprehensive Thinking Of High School Student

“ The High School Geography Curriculum Standards(2017 Edition)” emphasize the cultivation of students’ comprehensive thinking skills.Comprehensive thinking is a prominent feature of geography,it is also an important quality of thinking and ability for students to analyze and understand geographic processes,geographic regularity,and systems of human-territory relations.In teaching process,therefore,teachers need to provide a variety of materials and create visual teaching situations to cultivate students’ comprehensive thinking skills.As the continuous development of science and technology drives the mode of “Internet+Education”,science micro-videos with educational and popular science significance are emerging,the way of geography knowledge learning and presentation is also changing.Teachers can take advantage of such popular science micro-videos and apply them to geography classroom teaching,so as to achieve the purpose of cultivating students’ core literacy and promoting students’ all-round development which is the requirement of new curriculum reform and new curriculum standards.The literature research method was used to sort out the current situation of domestic and international research about “science popularization micro-video” and“comprehensive thinking”.On the basis of the questionnaire and classroom observation methods,teaching principles and teaching strategies for cultivating comprehensive thinking through popular science micro-video was proposed.This paper summarized access channels for popular science micro videos and sorted out the applicable chapters in Selective Compulsory 1 of the Humanities Edition of high school geography which adopt to cultivate comprehensive thinking by using science popularization micro-video,and the “El Ni?o and La Ni?a phenomena” in “Sea-Air Interaction” which belong to this book was used as a case study for teaching practice.The main contents of the study are as follows:Analysis of the current situation of using science micro-videos to develop students’ comprehensive thinking.The analysis of teachers’ questionnaires and classroom observation results reveals that some front-line geography teachers don’t have profound understanding of comprehensive thinking,the phenomenon of neglecting geographical comprehensive thinking cultivation still exists,and the overall level of comprehensive thinking among high school students is low.Most teachers agree with the effect of science popularization micro-video resources in students’ comprehensive thinking cultivation,but there is a phenomenon that difficult to find science popularization micro-video resources and lack relevant teaching strategy guidance and case references.To address the problems in the current situation,teaching principles and strategies were proposed.In the specific cultivation process,the principles of science popularization micro-video including scientific,purposefulness and appropriateness should be followed,and cultivate comprehensive thinking should from different dimensions,i.e.using science popularization micro-video to cultivate elemental comprehensive thinking by holistic analysis,spatial and temporal integrated thinking by process analysis,and local integrated thinking by regional analysis.In the actual teaching process,different teaching sessions use different teaching strategies,as using the popular science micro-video to create a context in the introduction session,analyzing and reproducing geographical events in the knowledge explanation session to break through important and difficult points,consolidating and expanding in the classroom conclusion session.Teaching practice with the aid of teaching strategies.Taking “El Ni?o and La Ni?a”as an example to construct and implement a teaching design for teachers,so as to provide some reference for teachers’ teaching application,a test was also developed to verify the effectiveness of the science micro-video in developing comprehensive thinking.The result shows that the appropriate use of science micro-video in teaching helps to promote and improve students’ comprehensive thinking and standards.
