【正文】 第一篇：合理利用信息化資源提高小學(xué)數(shù)學(xué)課堂教學(xué)效率，培養(yǎng)了學(xué)生舉一反三的靈活解題能力。由于有了多媒體的幫助，使課堂教學(xué)時間顯得很充裕，不但可以較快完成教學(xué)任務(wù)，還能對教材作適當(dāng)補充。如：小明有11本漫畫書，5本數(shù)學(xué)書，語文書比漫畫書和數(shù)學(xué)書的總數(shù)多2本，小明共有多少本書？（1）11+5=16本，162=14本；（2）11+5=16本，162=32本；（3）11+5=16本，16+2=18本。先讓學(xué)生選擇正確算式，接著問：要選第一組算式條件該怎樣改？要選第二組算式題里的條件該怎樣改？最后，讓學(xué)生親手操作電腦，選擇不同的條件和問題拼出完整的應(yīng)用題，自己解答出來，鼓勵學(xué)生編出不同的應(yīng)用題。學(xué)生在動手拼應(yīng)用題的活動中，不知不覺地掌握了應(yīng)用題的結(jié)構(gòu)。這樣利用電教媒體進行變式練習(xí)教學(xué)，既節(jié)省了時間，又豐富了教學(xué)內(nèi)容；既加大了練習(xí)密度，又變換了練習(xí)形式，提高了課堂教學(xué)效率?！?Two step teaching application questions ”, after the end of examples, and “ think ”: change one condition in the analysis, how to solve? If according to traditional methods of one one questions, draw line graph, analyzing the relationship between the number last column solution, a lesson will be very nervous, the consolidation of practice is also very difficult to use of multimedia presentation can quickly change third conditions on the base in 1 cases, draw line graph, let the students do and line segment to try to answer according to the flexible problem solving ability, cultivate students infer other things from one of the multimedia help, make the classroom teaching time is very abundant, not only can quickly plete the task of teaching, but also make appropriate supplement to the as: Xiaoming 11 ic book, 5 math books, Chinese book than the number of ic book and math book more than 2 of the total number of book, Bob?(1)11+5=16, 162=14。(2)11+5=16, 16 2=32。(3)11+5=16, 16+2= the students choose the correct formula, then ask: should choose the first group of expression condition of the how? To select second groups of formula problems in conditions of the how? Finally, let the students personally operate the puter, select the conditions and problems of different spell application plete, answer out of their own, to encourage students to make use of in handson spell application activities, imperceptibly to master the application use of audiovisual media variant practice teaching, not only save time, but also enrich the teaching content。not only increased the density of exercise, and transform the practice, improve the efficiency of classroom 、利用信息技術(shù)共享資源，協(xié)作發(fā)展。Three, the use of information technology resources sharing, collaborative ，可以提供形式生動活潑、內(nèi)容豐富、信息量大、具有交互功能的學(xué)習(xí)資源。教師可以不必把大量的時間和精力用在組織和，而只需把時間和精力放在為學(xué)生提供學(xué)習(xí)所需要的各種資源上，在幫助學(xué)生確定某一學(xué)習(xí)主題時，引導(dǎo)學(xué)生從何處獲取有關(guān)的學(xué)習(xí)資源，如何獲取，以及如何有效利用這些學(xué)習(xí)資源等。For primary school mathematics teaching application in network environment, can be lively and vivid, rich in content, form a large amount of information, interactive learning can do not have a lot of time and energy use in the organization and preparation of lesson plans, but only need to put time and energy in providing various learning resources needed for students, to help students learn in a certain theme, guide students to get the relevant learning resources, how to get from where, and how the effective use of the learning ，教師只是處于引導(dǎo)、點撥的主導(dǎo)地位，而真正體現(xiàn)了以學(xué)生為主體的學(xué)習(xí)模式，它強
