Education is intimately associated with communication, and so may utilize any technology that is able to support a process that enables information to be transferred from one location to another. This paper describes the meaning of the term multi-media data base and presents a model of its potential role in aiding message creation for the purposes of communicating educational material using many parallel channels. Some of the problems associated with the implementation of such systems are outlined.  相似文献

A cowse‐integrated programme of library instruction has been developed for the School of Civil Engineering at the Queensland University of Technology, Australia; library instruction being one of the means selected to improve the research efforts of fourth year project students. The programme has been developed through consultation between the Civil Engineering Research Project Coordinator and the Civil Engineering Reference Librarian. Its aims are derived from those established for the fourth year research projects. Attention is focussed on the nature of the programme and the impact of instruction on fourth year research project students. Students who had received extended library instruction were compared with students from the previous year. Evidence suggests that the instruction has improved the information seeking behaviour of the students and their literature reviews.  相似文献

This study employed a qualitative research design to investigate how instructional designers use evaluation in everyday design practice. While past research has examined how designers spend their time, how they generally make decisions, and expert-novice differences, little attention has been paid to use of context, input, process, or product evaluation, from the perspective of practicing designers. Based on interviews of practitioners, our findings included ten themes regarding how designers use evaluation to improve their products. While these results substantiate to some degree the claim that practitioners believe clients will not pay for formal evaluations, they also suggest that practitioners use evaluation in important but less formal ways. Other conclusions regarding the role of evaluation in design are provided and future directions for training and research are discussed.  相似文献
