question

Do you have a recommended way of using SuperMemo by 20 students on 5 computers?

answer

SuperMemo has not been designed for multi-access for many users (for multi-access see supermemo.net). This means that each students must have his own collection. He or she can use other students' or teacher's collections by copying the material or transferring its portions between collections. Lack of multi-access also means that, optimally, each student should always work on the same computer, where his collections are stored locally (unless they have to be accessed from a server, which may slow down some operations).

This would be an exemplary algorithm:

1. To each computer assign students in 5 groups (4 students each)
2. Install SuperMemo on all computers (it takes only 2MB and performs far better when run locally)
3. For each student, create his own collection: e.g. Tom.kno, Mark.kno, John.kno, Marta.kno. Multiple collections may also be used, if necessary. It is then recommended for each student to keep all his collections in a single same folder. Optionally, students could use a collection access password (defined in Tools : Options : Access : Password). This is not for privacy reasons, but may help avoid student A using a collection of student B by mistake (esp. if the contents of collections is identical or similar)
4. Occasionally backup all PC (e.g. by copying files in a round-robin circle A->B->C->D->E->A)
5. Occasionally run File : Repair collection. The more people use a computer, the more likely a mishap such as a viral infection, crash, accidental folder delete, etc.
