(i) Drills: These allow students to practice concepts through repeated questions.
(ii) Tutorials: They are self-instructional programs that guide the student through new materials, but which allow the student to move at his/her own pace. The student can repeat a lesson if he/she does not understand it the first time.
(iii) Simulation: These are basically ‘what if’ analyses. They use sound, text and graphics (multimedia) to bring about an outcome based on a specific scenario. Topics on different subjects are on CDs and can be played on the computer by students. Students can then learn at their own paces. Degree and Masters Courses are also obtainable on internet. These are made possible through on-line courses.
