First year engineering unit, ENB104 Engineering Materials, exam
map
Developed by Dr Tuquabo Tesfamichael and Moira Cordiner
Synopsis of the task (written examination) and its context
The supervised examina
tion
for a QUT unit
was on theory and practical studies centred on 13 main concepts. It was constructed by:
determining which
learning outcomes/
objectives would be used to create the criteria (see table 1)
mapping the questions to these main concepts and a
lso to the criteria (see the table 2 ). This was to ensure a balance, so that no particular concept or criterion
was over

assessed
–
this means that even though the number and nature of questions per topic may vary year to year, the
balance across the crit
eria
is
maintained. Mapping also ensured that the emphasis in the unit was reflected in the examination.
setting the questions by adhering to table 2.

Note the weighting across the criteria in the three far right columns. Applying theoretical and practical knowledge (K&A) is
the most heavily weighted as this is a
first year unit. The other two criteria are roughly equally wei
ghted.
