Ans: Many computer games with focus on education are now available. A simple example, in this case is an educational game, which plays various rhymes for little kids. Similarly many other edutainment packages, which provide a lot of detailed information to kids, are available. Now this time several dictionaries and large reference books have been converted from a traditional paper form to a hypertext format. Printed dictionaries for deaf users portray hand and facial gestures through line drawings with arrows to show movement, so multimedia dictionaries are clearly a superior format for communicating this dynamic language. One of the essential components of the learning process is social interaction. The informal peer learning is as important as formal teaching. Today, multimedia – learning materials are available on various platforms. Just like multimedia a collaborative learning environment integrates text, graphs, audio and video. The main elements of such kind of environment of learning are: Collaboration : The traditional CBTs require the student to work in self-study mode. But work without a tutor may be ineffective. Communication should be possible in any direction, learners can ask their tutors or talk to other learners. Distance Cooperation: The collaboration of such kind has no geographical boundaries. It has availability of telecommunication or Internet facility. It must for any collaborative environment. Deferred or Real Time Communication : This system will provide possibility to communicate with the colleagues and tutors in a time frame which is not immediate. Student can learn in a group situation not in real time but later, thus allowing more contemplation and depth. Distributed Data: Learning data, such as learning material, videos, graphics, text files etc. are no longer needed to be stored on the same information, which can be modified at a common place. However, a student should not be allowed to modify the data. Thus, proper data security measures need to be incorporated for such learning. Multimedia Interface: This natural way of interfacing may be provided by multimedia environment using audio and video communication technology. Question 2: (a) Explain basic features of ImageQ. Ans: ImageQ ImageQ is a windows 3.1 application but it can also play back on Windows 95, create slide show presentations well and provides a way to distribute them easily. ImageQ presentations comprise a series of background images and associated control scripts that add user interface controls, overlay images, and underlying programming to each slide. The slide strip window for each presentation contains either thumb nails or file information for each slide image and provide the means of navigating through the presentation at design time. The user must create these through code, which ImageQ will interpret only at runtime a major deficiency that other authoring system (such as Icon Author and Director) avoid by offering design tools to arrange interface controls visually without code. Once the images have been imported into an ImageQ presentation, they can then kept in their native formats or saved as .BMP or .HKF files. ImageQ’s programming language is difficult to work with, because it uses unconventional syntax and event handlers. Though ImageQ lacks design and programming tools, it does well with distribution. It is easy to build portable presentations as stand alone. Its real strength lies in ability to create traditional slide shows with prebuilt images and distribute them with no royalty. ( b).
