你好，其实 历史的车轮已驶入了一个全新的信息时代，网络已经成为人类最重要的工具，它对学校教育的影响是巨大而且深远的，有人在对教育发展史进行了深入分析后，得出一个结论：教育技术的每一次进步，都会带来教育方法和学习方式的革命性的变革。应用现代教育技术是现代科学技术和社会发展对教育的要求,是教育改革的需要。 近年来，我校一直在积极推动和促进现代教育技术在学校工作中的开发和应用，在教育教学改革的实践中，对运用现代教育理论和现代教育技术优化教学过程，高效益地造就出一大批适应社会需求的现代化人才进行探索。在我校，运用网络技术优化教学过程，提高教学质量的意识不断增强，在常规教学活动中广泛使用网络技术，这已经成为课堂教学不可或缺的主要手段，同时也为教学改革开辟了新的天地。网络运用于教育教学，促进学生自主化的学习已成为一种课堂教学改革的必然选择。研究如何有效地利用网络提高教学效益，促进学生发展是广大教师实践的需要。 在实践中，我们体会到：新课改要在全新的理念指导下进行实践才会取得良好的效果；运用现代手段构建现代化的课堂教学，可以帮助学生更好地学习，提高学生的学习能力；教师队伍建设是取得良好教育教学效果的命脉。 一、利用网络资源优势开展理论学习，树立新观念，指导新实践。 当前新形势下的我们清醒地认识到：教育和帮助教师树立新的教育观念是全面推进素质教育的前提，也是适应新课改的要求。《基础教育课程改革纲要》明确指出：充分发挥信息技术的优势，为学生的发展提供丰富多彩的教育环境和有利的学习工具。因此，我们加大了信息技术资源的投入，进行了信息技术与学习活动的整合，扩充了学习资源。 从2000年以来，我校充分发挥"侨牌"作用，多次争取华侨对学校信息技术教育设备的投入。华侨先后慷慨捐资100余万元，建起了具有前瞻性的、现代化信息技术设备和网络平台。我们充分利用现代化网络平台开展教师理论与业务学习，学校制定了教职工的教育理论学习计划，建立了教师学习网页，开辟了理论前沿、校长信息、教海探幽、科研培训、校内示范、一试身手等栏目。"理论前沿"栏目汇集了新课程通识学习的理论文章供教师学习；"校长信息"栏目汇集了由校长推荐的学习信息；"一试身手"为互动栏目，即将你学习后的感受及疑问以论坛的形式进行交流……促进了教师教育观念转变，有助于在教育实践中教育应面向全体学生转变，教育方法上应向学生为主体的转变。教育观念转变教师才会有全新的教育实践行为。 二、运用现代化教学手段，开展课堂教学研究，以促进教学质量提高。 高信息时代的来临，使以计算机网络与多媒体为核心的信息技术与教育的结合越来越密切，信息科技教育已成为学科教育的一个重要组成部分；

Information TechnologyInformation technology, as defined by the Information Technology Association of America(ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." Encompassing the computer and information systems industries, information technology is the capability to electronically input, process, store, output, transmit, and receive data and information, including text, graphics, sound, and video, as well as the ability to control machines of all kinds electronically.Information technology is comprised of computers, networks, satellite communications, robotics, videotext, cable television, electronic mail ("e-mail"), electronic games, and automated office equipment. The information industry consists of all computer, communications, and electronics-related organizations, including hardware, software, and services. Completing tasks using information technology results in rapid processing and information mobility, as well as improved reliability and integrity of processed information.Information Technology's Role TodayEvery day, people use computers in new ways. Computers are increasingly affordable; they continue to be more powerful as information-processing tools as well as easier to use.Computers in Business One of the first and largest applications of computers is keeping and managing business and financial records. Most large companies keep the employment records of all their workers in large databases that are managed by computer programs. Similar programs and databases are used in such business functions as billing customers; tracking payments received and payments to be made; and tracking supplies needed and items produced, stored, shipped, and sold. In fact, practically all the information companies need to do business involves the use of computers and information technology.On a smaller scale, many businesses have replaced cash registers with point-of-sale (POS) terminals. These POS terminals not only print a sales receipt for the customer but also send information to a computer database when each item is sold to maintain an inventory of items on hand and items to be ordered. Computers have also become very important in modern factories. Computer-controlled robots now do tasks that are hot, heavy, or hazardous. Robots are also used to do routine, repetitive tasks in which boredom or fatigue can lead to poor quality work.Computers in Medicine Information technology plays an important role in medicine. For example, a scanner takes a series of pictures of the body by means of computerized axial tomography (CAT) or magnetic resonance imaging (MRI). A computer then combines the pictures to produce detailed three-dimensional images of the body's organs. In addition, the MRI produces images that show changes in body chemistry and blood flow.Computers in Science and Engineering Using supercomputers, meteorologists predict future weather by using a combination of observations of weather conditions from many sources, a mathematical representation of the behavior of the atmosphere, and geographic data.Computer-aided design and computer-aided manufacturing programs, often called CAD/CAM, have led to improved products in many fields, especially where designs tend to be very detailed. Computer programs make it possible for engineers to analyze designs of complex structures such as power plants and space stations.Integrated Information Systems With today's sophisticated hardware, software, and communications technologies, it is often difficult to classify a system as belonging uniquely to one specific application program. Organizations increasingly are consolidating their information needs into a single, integrated information system. One example is SAP, a German software package that runs on mainframe computers and provides an enterprise-wide solution for information technologies. It is a powerful database that enables companies to organize all their data into a single database, then choose only the program modules or tables they want. The freestanding modules are customized to fit each customer's needs.
