What it is
Group Machine is a application that can form groups from a list of names, or select one random name at a time from this list.
You determine the group size from either how many students you want in a group or from how many groups you want to exist.
When creating groups, It thus takes away the burden of debating with the students about who should be together or in certain groups. It also removes the angst of individual students of (not) being chosen by fellow students or from having to position themselves into a desirable group.
It requires Microsoft Excel! (2003 and up)
