Advantages - Creates access for the classroom with only one computer. Works great if material is self-explanatory. Disadvantages - It takes a long time for each student to get a turn. Some students will require individual tutoring. A student will miss the regular class activity while doing the individual project.
Students work on computers outside of the classroom.
Advantages - Doesn't use class time. Solves for the school where access is only available somewhere else. Disadvantages - Some students will need technical help. Will work best with group projects. Lack of supervision may be a problem and will require especially detailed instruction.
