【正文】 teaching, a change in the traditional blackboard + chalk a mouth, a book single teaching methods, the geography classroom bees live, vivid and efficient. Some experience in teaching.First,Create situations, to stimulate interestSuhomlinski pointed out that all the intellectual work, we must rely on interest. Multimedia teaching the use of text, sound, images, animation, and network transmission means of puter technology in the classroom can be achieved bining static and dynamic sound and picture synchronization, greatly improving the students39。 interest, and to cultivate the students a variety of capacities, and strive to achieve the best effectiveness of teaching. Appropriate use of multimedia animation, bined with interesting graphics and wonderful sound teaching, teaching content more attractive, more focus on the students39。 attention. In teaching students to create a Quest situation to attract them into the imagination, abstract things concrete, to achieve the purpose of mastery of knowledge. I import the world39。s climate unit. Use PowerPoint to make a set of slides, 13 of the world39。s major climate typical landscape unfolding, acpanied by beautiful background music, the last title in the world39。s climate and several Questions. Students39。 attention all the focus to the sensual and elegant on the screen, sparking them to learn and explore the interest of the world39。s climate, and actively learning.Second, focused, Overing DifficultiesGeography lesson many major and difficult, sometimes alone teachers on the students understand very laborious. And the use of multimedia tools, animation, the procedure shows a partially enlarged, can not express, difficult to understand abstract and plex process of change, subtle structure into visual image rich, dynamic, innovative, interesting, beautiful music, appeal strong observation, viewing screen, can make it difficult to understand the focus of the difficulty bees image, specific, vivid, clear and easy to understand, so that teaching a multiplier effect. Earth39。s rotation and revolution impact on the climate is more abstract, both in this chapter the difficulty of teaching is the key. The seventh graders lack of spatial imagination, it is difficult to understand. I39。m teaching this knowledge with Flash for a period of the Earth around the sun to the analog animation: the vast sky, sweet music to the background, the Earth at an angle leaned to revolve around the sun, the sun in the center position steady stream of light radiation and parallel beam irradiation surface of the Earth. When the Earth39。s rotation to a specific location on the screen Equinox, summer solstice, autumnal equinox, Winter Solstice and their corresponding high brightness will blink. Students through the animation very intuitive understanding of the sun39。s direct light point move, changing seasons, changes in the length of the day and night and polar day and polar night abstract knowledge of geography.Third, the dynamic map, vividThe map geography second language, geography teaching is inseparable from the map. But the usual map is flat, but the content is not strong, plex, targeted theme is not prominent, some space is needed to imagine geographical knowledge (such as contour the hypsometric map), due to the seventh graders space concept not yet established, to be pletely read it is difficult to understand. If you use multimedia to produce twodimensional, threedimensional animated maps, and the use of color change, brightness, blinking, to improve map clarity, transparency, discrimination, and these problems will go away. I am teaching the world39。s average temperature distribution law knowledge points, making the electronic map. Talked about from low latitudes toward the poles temperature decreased this law, the corresponding region in the map according to the laws bright flashes, the students can understand. World average precipitation distribution and the world39。s major climate type of teaching I use this electronic map, and achieved good results.Fourth, electronic blackboard, intuitive and timesavingThe multimedia blackboard supplements are a lot of teachers are often used as a method. The contents of the electronic blackboard can be acpanied by teachers on the timely, as a supplement to the knowledgespeaking general and sublimation, coordination with the teachers explain, greatly improving the effectiveness of teaching. At the same time, pared with the traditional blackboard, electronic blackboard can save writing time, interrupted to explain ideas to avoid writing writing on the blackboard, can improve efficiency. I produced a courseware in teaching with knowledge: in marked with five equator and the Tropic of Capricorn and Tropic of Cancer, the north and south poles and pole side of the diagram of the earth is to introduce the text description of the characteristics of boreal, temperate and tropical, side each with a typical landscape pictures, click on the picture will play the video of these landscapes and short voice. In the teaching of the world39。s 13 major climate types, I also used a similar electronic blackboard, saving time and vivid, with good results.The new curriculum stressed the need to change the way teachers . The rapid development of multimedia technology and wide application, for teachers to achieve the teaching way transformation provides a new powerful technical support and material preparation. The application of multimedia technology in geography classroom teaching, changing the traditional chalk blackboard + a mouth, a book single teaching way, make the geography classroom bee alive, vivid and efficient. The following is my personal experience in teaching. One, the creation of context, to stimulate interestSue Home Linsky pointed out that all intellectual work depends on interest . Multimedia teaching the use of text, sound, image, animation, network transmission, puter science and technology, in the classroom can realize the bination of static and dynamic, synchronized sound, greatly enhance students39。 interest in learning, thus cultivating student39。s various ability, and strive to achieve the best teaching effect. We appropriately using multimedia animation, with interesting graphic and excellent sound teaching, make the teaching more attractive, more focused the attention of students. In the teaching process for students to create a quest situation, draw them into the space of imagination, the abstraction of specific things, to achieve the purpose of knowledge. I39。m in world climate unit. Using PowerPoint produced a group of slides, will be the world39。s 13 major climatic ty
