When it comes to distance learning, many people find it to be a convenient and efficient way to earn a degree or certificate, or to expand their knowledge in a particular field. Distance learning, which typically takes place on the internet, allows individuals to access learning materials from any location, at anytime. Though many online courses are offered as part of distance learning, the process actually encompasses a number of forms of academic learning. For example, correspondence courses and telecourses are also distance learning methods by which individuals gain knowledge. The quality of distance learning varies depending on the nature of the course or program, the school, and the mode of delivery. In some cases, such as university courses, the quality of the program can be equal to that of an on-campus course. However, the quality of instruction often varies depending on the Internet curriculum and materials, the availability of instructor support, and the knowledge of the individual instructors. Distance learning also has some disadvantages, such as the lack of face-to-face contact with teachers and classmates, limited access to resources, and the lack of recognition by employers in certain fields. In addition, some courses require a particular type of equipment or software, which can add to the cost of participating in a program. Despite its drawbacks, distance learning can be an effective way to gain knowledge or a degree. Individuals who are self-motivated, well organized, and have the technical skills necessary to work on the computer can benefit from taking courses via the Internet. For those who have limited time, resources or money, or may not have access to a local college or university, distance learning can be a great way to achieve educational goals.
