There is a mini-quiz at the end of this lesson. The delivery of instructional material and information through a computer has two major goals. One is that it can either replace a textbook through the use of online documentation. Online documentation Textbook or written class material can be replaced by online documentation, available on disk or downloaded from the Internet. A distinct advantage of delivering educational material this way is reduced costs.
Text books can be very expensive.
Many commercial software manufacturers have replaced written documentation with an online version. The most common program for distributing online documentation is Adobe Acrobat . Online documents can look just like the hardcopy document, but they can also include hyperlinks and jumps. A major disadvantage of providing class material this way is the difficulty in reading extensive material off the computer monitor. The delivery of education material in the form of a CBT can replace classroom instruction.
