As an ex Liverpool Uni student (late 1970s)...

These are 1st years so beginners - not doing theses yet.

However, something that makes them think as well as do can be useful.

The Vaughan & Geddes paper here: http://www.radstats.org.uk/no099/index.htm
gives something to look at in terms of impacts of connectedness and links to 
social factors. 

Liverpool used to have segregated orange and green (Belfast-style) areas that 
were broken up by slum clearance in the 1960s associated with building large 
estates on the edge of town (now some in Knowsley). 

The physical form of terraces, social housing and more recent housing 
association building will reflect these and other changes. As will how bus 
routes reflect housing, work etc patterns. Bus route relations may be more 
advanced than this course....

uses OS buildings but does not go down to high zoom levels. 

Filling in buildings in OSM especially in areas where visible smartphones may 
not be totally advisable may be especially useful.  Walking or cycling through 
with gps in pocket may help determining connectivity.

More here on how to do the datashine maps.
