In recent years, educators have witnessed the rapid development of computer networks, dramatic improvements in the processing power of personal computers, and striking advances in magnetic storage technology. These developments have made a computer a self contained teaching in distance education, providing a new and interactive means of overcoming time and distance to reach learners. Online continuing education brings this learning into your office or home so you are able to learn at your own pace, at your own time and at your convenience. With a wide range of courses, tests and exams offered online, you can develop your skills and gain your certifications quickly and easily. Many local, regional and national professional organizations offer training and exams online, you save time and money, while getting the necessary qualifications and increasing your knowledge in your field.
Distance education is a standard form of instruction for many colleges and universities nowadays. Online colleges make their own self contained teaching materials for learning outside the campus. Nationally accredited online universities work out a self contained teaching program for homeschoolers, based on a unique self contained teaching methodology.
It is hard to undervalue the impact of Computer Assisted Instruction on the explosion of distance learning programs. The CAI blends the very best of traditional learning with all of the advantages of E-learning.
Computer Assisted Instruction (CAI) - uses the computer as a self contained teaching machine to present discrete lessons to achieve specific but limited educational objectives. There are several CAI modes, including: drill and practice, tutorial, simulations and games and problem-solving.
It is a well-known fact that computers facilitate self paced learning. In the CAI mode, for instance, computers individualize learning, while giving immediate reinforcement and feedback. What is more, computers are a multimedia tool. With integrated graphic, print, audio and video capabilities, computers can effectively link various technologies. Interactive video and CD-ROM technologies can be incorporated into computer-based instructional units, lessons and learning environments. Computers are also interactive. Microcomputer systems, incorporating various software packages, are extremely flexible and maximize the learner control. As computer technology is rapidly advancing and innovations are constantly emerging- related costs drop. By understanding their present needs and future technical requirements, a cost-conscious educator can effectively navigate the volatile computer hardware and software market. Local, regional, and national networks link resources and individuals, wherever they might be. In fact, many institutions now offer complete undergraduate and graduate programs, relying almost exclusively on computer-based resources.
The use of CAI is commonly associated with the other beneficial outcomes, containing a greater internal locus of control, school attendance, a motivation/time-on-task and a student-student cooperation and collaboration than the use of conventional instruction alone.
