Multimedia represents a radical change in how information can be presented or communicated and, more importantly, in how learners can access and retrieve information. Multimedia CD-ROM technology enables learners actively to engage more of their senses in the learning process as well as to develop their information searching skills and strategies.The information age-with its subsequent philosophical changes in teaching and learning-has caused information professionals to redefine the processes of information access and delivery. Educators face the challenge of preparing learners to make decisions about and make sense of the vast amounts of information that they will face as independent learners.Information skills-such as sifting data, seeking relationships relevant to a task and finding coherent ways to present conclusions-are forming the basis of many schools' curricula and programmes. With the advent of multimedia CD-ROM information resources it is being recognised that different skills are required for searching and effectively utilising material from such mass-storage media. CD-ROM (Compact Disc Read-only Memory) is a digital optical medium for storing vast amounts of computer data. Each disc can hold around 600 megabytes or the equivalent of about 250,000 typed A 4 pages (Steadman, Nash and Eraut 1992, 5).Hedberg and Harper (1 9 9 2 , 2 19) outline the major growth in the application of hyperand multimedia resources for teaching and learning. Chen (1990, 267) states that 'multimedia technologies have changed how we demand information, and for the first time, a learner is learning how to learn and an information seeker is learning how to ask for information'. Because of the multimedia nature of such software, students, teacher librarians and teachers are not only confronted with text and graphics but must now deal with sound, animations and video delivered by hypertext.For teachers and teacher librarians then, the challenge is not 'can multimedia improve our understanding of information?' but, instead 'how can we use this technology to
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
