Material Detail



REA Modeling involves indentifying cardinalities (relationships) between entities. Stevie is a 20 question drill and practice piece that includes graphics and prompts to establish the minimum and maximum cardinalities for each example. Feedback enabled responses promote repeated trials. A user id and password of 'merlot' (lower case) provides access.... Show More

This is an excellent drill and practice piece that will help students understand
how to identify the minimum and maximum cardinalities of relationships in REA
modeling. Instructors could also use Stevie as an in-class demonstration or
exercise to facilitate discussion. Both the minimum and maximum cardinalities
for the left and right relationships between entities are required. Feedback is
provided for incorrectly identified relationships, so one can 'try again' until
a proper response is achieved.

Students would need to know the rules associated with determining cardinalities
prior to using Stevie. While one can figure out how to use Stevie through trial
and error, preliminary instructions would likely to be helpful.
