With voice mail, complete interactions can take place asynchronously. The student has a question that needs to be answered outside of regular class hours. The instructor can a dial the student's voice mailbox and leave a complete answer when it is convenient. Because this can be done from any phone in the world, instructor's can be accessible to students at all times. This service will reduce the student's sense of isolation.
Students access the computer based system by regular telephone.
A menu is presented and students select the option they want by touching a number on the telephone pad. The system branches to that content and can present information. A second menu provides a branch to a self-test. The system asks and questions and provides a menu of answer options which correspond to the telephone keypad. Students touch the number that they think is right.
