The Internet is becoming one of the most important tools in the educator's or trainer's toolbox. Internet-based education and training have been experimented within many countries. Already, materials and courses, ranging from a simple syllabus to highly structured courses developed by instructional design experts, are available.
Some courses are free, while others require a high fee.
Some courses are well designed, and while other are not. Some online courses are offered as an extension to conventional courses, and others are created just for the Internet environment. There are also few dedicated institutions that only provide Internet-based courses. Internet-based education is a form of distance education in which the course contents are delivered and the interactions are provided by the technologies and methodologies of the Internet. Moreover, the independent time and distance of the Internet allows learners to enroll in a course from anywhere in the world at any time.
