1、1STRATEGIES FOR WEB BASED INSTRUCTION IN DISTANCE EDUCATION IntroductionDistance Education has come a long way from its humble beginnings in correspondence courses to an era when we speak of learner centred virtual universities. Over a period of one century, print has been supplemented first by radi
2、o; later by television, and more recently by the Internet and the World Wide Web.Such growth was made possible by an exponential growth in electronics. Technological inputs into distance education started with the simple radio and the transistor which formed the basis for very successful distance pr
3、ogrammes in agriculture ( Radio rural forums in Canada and India; School on the air in Latin America). A later development of television enriched distance education by opening the possibilities of incorporating the audio and visual medium and televisions use in education, at least in India received
4、a boost with the Satellite Instructional Television Experiment in 1975. Distance education institutions did not lag behind in their use of the latest media technology available in their efforts to reach out to students irrespective of time and distance, whether in the U.K. Open University or in simi
5、lar institutions in Germany ( Feruniversitat) ; NHK in Japan; or the Chinese Television University. Broadcast of educational television became more flexible with the use of audio and video cassette recorders enabling anytime study for the learner. The computer and the satellite converging together p
6、aved the way for the Internet and the World Wide Web. Coupled with findings from research into the cognitive and learning sciences, we have now come to an age where web based instruction is an immediate precursor to the virtual university, with Internet as its platform. The technological possibiliti
7、es have made collaboration and cooperation a must. It is the purpose of this paper to explore strategies in crucial areas and various mechanisms for collaboration. Strategies for Pedagogical inputs for Web based instructionThe Internet and the World Wide Web were the outcomes of developments in the
8、Information Technology industry. Pioneering academicians saw the potential of the Internet and World Wide Web, as a rich resource of information to supplement 2classroom teaching. The more enterprising academics went ahead and began to offer programmes or courses of study on the Internet i.e. web ba
9、sed instruction. However if instruction can be defined as a purposeful interaction to increase learners knowledge or skills in specific, pre-determined ways ( Critchie Hoffman- 1997), then, simply publishing a World Wide Web Page with links to other digital resources does not constitute instruction.
10、 Instructional sequences typically embrace seven common elements: motivating the learner, specifying what is to be learned, prompting the learner to recall and applying previous knowledge, providing new information and offering guidance and feedback, testing comprehension and supplying enrichment or
11、 remediation (Dick Reiser 1989). With forethought, each of these elements can be incorporated in instruction designed for delivery on the World Wide Web, to ensure that the pedagogical strategies are met. Self learning materials in Distance education typify a scientific effort at incorporating these
12、 seven elements. The pedagogy of self learning materials has to be enlarged and adapted keeping the delivery systems ( in this case, the WWW) in constant focus. With pedagogical strategies being met, online courses or web- based instruction is bound to grow in popularity and provide the means for gr
13、eater access.Prof. S.W. Tam, in his paper entitled Managing Learner Centredness: The role of effective student support in ODL presented at the recently concluded Asian Regional Conference of The ICDE ( Nov. 2000) observed that one of the hallmarks of distance education and indeed what has made it su
14、perior to face- to- face education is the emphasis placed on making instructional design and development an integrated aspect of ODL. He laments the fact that with the advent of new modern technologies and the way they have become pervasive in distance education many people erroneously think that th
15、e design of instruction does not matter as long as there is the medium to convey the facts that we wish to provide the students. In distance education, as in any other form of education, the aim of education is not just to convey facts but to convey knowledge in such a way that the student can synth
16、esise it. Also, efforts are made in the ODL system to make students Learn how to learn. Prof. Tam refers to the analysis of 25 years research in ODL done by Clark ( 1983) and quotes Clarks opinion that the primary active ingredient in studies in instructional methods were the strategies and not the media employed by course designers and instructors. At OUHK, this is just as true today as Clark found it in 19
