Secondary and elementary teachers are able to supplement classroom instruction. Students can meet children from other countries or take a trip to the zoo without leaving the classroom. Businesses use distance learning to offer training to their employees. In most cases, it is much less expensive for a company to offer this training with the use of technology. Group projects involving individuals from several corporate sites can be accomplished easier.
Frequent meetings are feasible because there is minimal or no travel involved.
There are many different types of mediums used for distance learning. The simplest is television. Broadcasters such as PBS show educational programming for educators to use in the classroom or to tape and show later. Video tape fits in this catagory as well. This type of technology is becoming more prevalent on the desktop.
