If you have your students start with a map that you create for them then you might be able to achieve what you're after.

The default basemaps all use Web Mercator Auxiliary Sphere as their spatial reference (102100). If you create a map with a 'custom' basemap and that service does not use the default spatial reference, then the basemap gallery will be disabled.
