Paced and self-paced models[ edit ] Distance education can be delivered in a paced format similar to traditional campus based models in which learners commence and complete a course at the same time. The ability to complete a course at a pace that is appropriate for each individual is the most effective manner to learn given the personal demands on time and schedule. The goal of computer-based multimedia is to integrate various voices, video and other computer technologies into a single easily accessible delivery system. Starting in the s, private schools opened across the country which offered specialized technical training to anyone who enrolled, not just the employees of one company. This helps the students have experiences of the classroom and social interaction that they are unable to receive at home or the hospital, while still keeping them in a safe learning environment. Al l these computers are connected to each other i n a complicated pattern. Distance learning DL on the internet usually takes place i n one of the following forms. By including a mechanisms for students to ask questions publicly, all students benefit from the answers provided. With the freedom of teaching an online class comes the added responsibility of interacting with students who attending class all hours of day and night, who need their faculty-and rightfully expect them to be in regular attendance and communication. For those in a healthcare or mental health distance learning program, online-based interactions have the potential to foster deeper reflections and discussions of client issues  as well as a quicker response to client issues, since supervision happens on a regular basis and is not limited to a weekly supervision meeting.
Mail correspondence, which is the oldest form of distance education, is an asynchronous delivery technology, as are message board forums, e-mailvideo and audio recordingsprint materials, voicemailand fax. Students are not required to be together at the same time.
A single frame can be stored in one rotation of the disc. Students who take online courses often set aside specific hours to do their online work, not unusually when few other people are awake.
However, such discussions should not merely be created and left with no faculty oversight.

Paced courses may be offered in either synchronous mode, but self-paced courses are almost always offered asynchronously. Unless professionally prod used, ITV programmers often look amateurish. Daniel Barwick noted that there is no evidence that large class size is always worse or that small class size is always better, although a negative link has been established between certain types of instruction in large classes and learning outcomes; he argued that higher education has not made a sufficient effort to experiment with a variety of instructional methods to determine whether large class size is always negatively correlated with a reduction in learning outcomes. For example, two-way video conferencing enables people at different locations to have two way video communications i. Passive-ITV typically involves pre-produced programmers, which are distributed by videocassette or by video-based technologies such as broadcast, cable or satellite. While both allow for class discussion, asynchronous forums allow students to participate when they choose; synchronous discussions require availability at a specified time. In the United States, William Rainey Harper , first president of the University of Chicago , celebrated the concept of extended education, whereby the research university had satellite colleges in the wider community. These tools also support asynchronous participation by students being able to listen to recordings of synchronous sessions. It is the most popular medium as it is easy to carry, is comparatively cheaper and can be used according to the convenience of the learners. Students can then manipulate the coursework to fit their learning by focusing more on their weaker topics while breezing through concepts that they already have or can easily grasp.
However, phone-in-radio programs provide an opportunity for interactivity between students and the teacher, but the level of interactivity and participation rates are often low Bates et.
There are many available that cover a broad range of topics. Inserting a "Question the Instructor" forum into the course minimizes students' dependence on e-mail.
However, this is little correlation between student performance when comparing the previous different distance learning strategies.
