Collaborative Testing and Test Performance  
Does collaboration on a test, independent of prior collaborative learning, 
affect test performance?   In almost all the descriptions, demonstrations, 
and studies of collaboration testing and academic achievement, the effect 
of collaborative learning on achievement is conflated with the effect of 
collaborative testing alone.  The results of this study show that 
collaborative testing alone has a significant positive association with 
test performance that varies by the level of cognitive processing  reflected 
in the test question.
