On-campus education vs. online education! Is one better than the other? Can one completely replace the other? Indeed it seems that online education is the way of the future. Educational institutions, corporations and government organizations alike already offer various forms of electronic teaching. However, can a computer truly replace a teacher and a blackboard?
How people learn
Each individual has a form of learning that suits them best. Some individuals achieve fantastic results in courses taught online, however most people drop out of 100% computer-led courses. Educational institutions, as well as companies in carrying out staff training, must recognize that there is no ideal way to carry out the teaching of a large group of individuals, and so must design programs that best suits the needs of the group as a whole.
People learn using multiple senses. This involves learning through both theoretical components of a course, as well as social interaction with both instructors and other students. Students learn from each other's mistakes and successes, not just from what they are told by instructors.
Each individual student has an ideal learning pace. Instructors are therefore faced with the challenge of designing courses that move forward such that those students with a slower learning pace do not get left behind, while not moving so slowly that students with faster learning paces get bored.
In the age of high-speed information transfer, online education is becoming a popular and cheap means for delivering teaching to individuals outside the classroom, and in some cases all over the world. Teaching can be via CD, websites, or through real-time online facilities such as webcasts, webinars and virtual classrooms. However, different methods of online education each have their own advantages and disadvantages.
Online education is still a relatively new concept, and in many respects still in the teething stages. As such, various problems arrive across different online education environments. For example:
1. Lack of immediate feedback in asynchronous learning environments: While some online education environments such as webcasts, webinars and virtual classrooms operate live with the addition of an instructor, most do not. Teaching that is delivered through a CD or website, although having the advantage of being self-paced, provides no immediate feedback from a live instructor.
2. More preparation required on the part of the instructor: In an online education environment, an instructor can not simply stand in front of a whiteboard and deliver a class. Lessons in online education environments must be prepared ahead of time, along with any notes and instructions that may accompany the teaching.
In many cases it would also be necessary that the instructor not only understands the concepts being taught, but the technology used to deliver that teaching. This therefore increases the skill-levels needed of online education instructors, placing greater demand on educational institutions.
Staffing levels may also be higher for courses run in an online education environment, requiring for example:
The Instructor - able to teach both course content and be skilled in the use of technologies involved
The Facilitator - to assist the instructor in delivering content, but may do so remotely
Help Desk - to offer assistance to instructors, facilitators and students in the use of both software and hardware used to deliver the course.
3. Not all people are comfortable with online education: Education is no longer only sought by the world's youth. With an increased trend towards adult and continuing education, there is a need to design courses suitable for students over a larger age-range, as well as students from different and varied backgrounds. It is difficult, however, to design online education environments suitable for everyone.
4. Increased potential for frustration, anxiety and confusion: In an online education environment, there are a greater number of parts making up the system that can fail. Server failures may prevent online courses from operating. Software based teaching applications may require other specific components to operate. Computer viruses may infect software necessary to run online education environments. If these systems are complex, students may choose the ease of On-campus education rather than taking the additional time and effort necessary to master the use of online education systems.
