Based On 3D Holographic Projection,this Paper Explores The Classroom Practice Of Atmospheric Movement

The New Geography Curriculum emphasizes making full use of modem information technology to create a teaching environment conducive to students'formation of geographical information consciousness and ability,and to improve students'ability to use information technology to solve geographical problems;it cultivates students'essential geography core literacy as well as improves students'ability of geography learning and survival.In the face of the new requirements of new curriculum standards and the development of Time,traditional teaching methods and teaching modes cannot meet their demands.3D holographic projection,with its own unique advantages,optimizes the teaching environment,stimulates students'learning interest and thirst for knowledge and improves the effectiveness of classroom teaching and learning,promoting the teachers'and students'comprehensive quality by changing the presentation of teaching material and the organization of content.This Paper,which is based on the application of teaching practice connected to 3D holographic projection in "The unevenly heated air causes the movement of the atmosphere",is to explore the advantages,feasibility and the necessity of 3D holographic projection in the application of high school geography teaching,and in view of its corresponding insufficiency,the corrective measures are put forward.First of all,we use 3D holographic projection to create a virtual geographical environment for immersive and three-dimensional advantages to stimulate students'interest and enthusiasm in learning.Secondly,using the 3D holographic projection to change the presentation mode of the geographical phenomena such as the atmospheric layer structure and the thermal circulation,create the virtual simulation geographical environment to make the students explore the geographical phenomenon,thus the perceptual knowledge of the 3D is raised to the rational understanding,and the students'comprehensive analysis ability is cultivated.Through the classroom practice in this lesson,we can see that 3D holographic projection has the following advantages in geography teaching:expand the teaching capacity;deepen understanding and enhance teaching effectiveness with three dimensional demonstration of the occurrence and development of geographical phenomena;create a virtual geographical environment with immersive feeling,promoting students'autonomy and cooperation,and cultivating students'ability of independent learning and cooperative inquiry;use their interactivity to operate geographic phenomena in virtual environment,and observe their development and change,cultivating their core literacy.Finally,the soft environment of 3D holographic projection with spatial sense,immersion and sense of science and technology helps to cultivate and enhance the students'innovative consciousness and ability,and to enhance the students'necessary ability to adapt to the needs of the future development.At the same time,because the application of 3D holographic projection in teaching is still in its infancy,there are some deficiencies:3D teaching resource repository is still not perfect and interaction needs to be strengthened,in particular,interaction applications with other teaching devices need to be strengthened.With the continuous development and perfection of 3D holographic projection technology,through developing the cooperation mechanism between colleges and improving 3D database resources of the interaction and immersion,teachers can cross the limit of time,space and teaching conditions,to show students geographic principle and geographic phenomena with the feature of abstraction and spanning space-time by presenting them tridimensionally in order to satisfy the future need of teaching practice,enhancing the effectiveness of teachers'teaching and students'learning.As one of the advanced technologies,with the continuous development and perfection of the 3D holographic projection technology as well as the development of the school enterprise cooperation mechanism and the improvement of the teaching resources,it will be the same as the previous teaching equipment,such as multimedia and electronic whiteboard,becoming an important tool to promote teaching reform,innovate teaching mode and teaching means as well as do good to teachers'growth.This Paper,which has significance in scientific research,will provide theoretical and practical reference for the application of 3D holographic projection in geography teaching and even in other subjects.
