History of Education Technology Do we still teach in the same way as in 50 or60 years ago? Why? Why not? Upto what extent do the technologicaladvances influence our teaching practice?
Some important concepts...Some important concepts...o Technology can refer to material objects of use to humanity, such asmachines or hardware, but it can also encompass broader themes,including systems, methods of organization, and techniques.o Educational technology refers to technology that is employed in theclassroom for the purpose of student instruction (Buck, 1994). It is allabout computer-based technology including computer hardware,software, CD-Rom, videodisc player and the Internet. These forms oftechnology provide teachers and students with vast quantities ofinformation in an easily accessible, non-sequential format that can beused as teaching tool.
Aiding the teaching practicesince 1800... Teaching has changed throughout time. The teaching tools that educatorsused to aid their practice had changed as time went by... One of the very first elements used in the classroom by teachers to aidtheir teaching practice was the blackboardblackboard. In 1801, the blackboard had a lasting impact on the way instructors taught.Not only did blackboards become very popular very quickly, they requiredfewer writing materials for schools and students who could not alwaysafford paper and pencils. Prior to the ingenious invention, teachers had no way of visuallypresenting spelling!
What´s on...? Commercially available since the late 1920s, the television sethas become commonplace... Television can be a powerful educational tool, but if we wantour students to absorb specific content from what they see, weneed to give them a model for viewing that is active and critical.(interactive view) The t.v. helps teachers when they need to demonstratesomething they cant show in any other way. It makes studentspractice skills such as note taking, problem solving, predicting,listening, etc.
Computers The first electronic digital computers were developed between 1940and 1945 in the United Kingdom and United States. Originally theywere the size of a large room, consuming as much power as severalhundred modern personal computers (PCs). In this era mechanicalcomputers were used for military applications. Computer technology has had a deep impact on the education sector.Thanks to computers, imparting education has become easier andmuch more interesting than before. Owing to memory capacities ofcomputers, large chunks of data can be stored in them. They enablequick processing of data with very less or no chances of errors inprocessing.
Connecting the world...@ The Internet has revolutionized the computer and communicationsworld like nothing before. It is at once a world-wide broadcastingcapability, a mechanism for information dissemination, and a mediumfor collaboration and interaction between individuals and theircomputers without regard for geographic location.@ Teachers seem to use it for just about everything: development,updating language skills, finding materials, learning about computerapplications, keeping in touch with friends and colleagues, teaching,working on class projects and activities, and just having fun.
Who wants to come to the front?o Interactive whiteboards are used inmany schools as replacements fortraditional whiteboards orflipcharts. They provide ways toshow students any thing which canbe presented on a computersdesktop (educational software, websites, etc.)o They allow teachers to record theirinstruction and post the material forreview by students at a later time.This can be a very effectiveinstructional strategy for studentswho benefit from repetition, forstudents who are absent fromschool, for struggling learners, etc.
Call me...o Smartphones provide us withinstant connectivity to ourfamily and friends and access tothe Internet at G-denotedspeeds.o A student with a smartphone inthe classroom that uses itresponsibly can become a moreindependent and resourcefullearner, not only inside theclassroom, but outside of theclassroom as well.
To summarize... We live in the age of the computer,and there are growing demands onalmost everyone, includingteachers, to becometechnologically literate. Computer-aided teaching adds afun element to education. Teachershardly use chalk and board today.They bring presentations on a flashdrive, plug it in to a computer inthe classroom, and the teachingbegins. Theres color, theres sound,theres movement - the same oldinformation comes forth in adifferent way and learning becomesfun.
