Domain Testing: Divide and Conquer - Testing Education

� Testing the dependent variables separately by first finding
their dependency relationships
• Afternoon session (90 minutes):
� Performing all pairs combination of test cases of actual
computer application functions
� Identifying independent and dependent variables of the
functions
� Combining independent variables using all pairs
combination technique and testing dependent variables
separately based on dependency relationships
Day 5 -- See Appendix M and Appendix N
• Morning session (150 minutes):
� Paper-based posttest
• Afternoon session (150 minutes):
� Performance-based posttest
5.07 Experimental Error
After trying the training material on 18 learners, I realized that I had made an error
in the instructional objective that required the learners to be able to do all pairs
combination. I misinterpreted and misunderstood the method of doing all pairs
combination, so obviously what was taught to the learners was incorrect. Dr. Kaner
pointed out this blunder when he and other evaluators were reviewing the

Having corrected my understanding of the all pairs combination technique, I
