  The use of Data Retrieval Tests (DRTs), as an alternative to physics
laboratory notebook marking, is discussed. The implementation of a
Moodle-based, on-line DRT for 1st year physics students is described. The
advantages of using such a methodology are highlighted and student comments
shown. The paper also describes how students change their behaviour as a
consequence of having an end of module DRT via 'bootstrapping', both singly and
in peer groups.
