First year engineering unit, ENB104 Engineering Materials: exam (short answers) criteria sheet

Developed by Dr Tuquabo Tesfamichael and Moira Cordiner

The example here is for the 2006 semester 1 examinationfor a QUT unit.

Synopsis of the task (written examination) and its context

This supervised examination was on a set of theoretical concepts and practical activities. The exam comprised multiple choice (20/100 marks) and short answer questions (80/100 marks). These marks were allocated to particular criteria. The criteria sheet is only for the short answer questions, not for the multiple-choice questions. This is because responses to multiple-choice questions do not lend themselves to being described on a five standard scale. The answers to multiple choice questions are either correct or not (a one standard scale). The evidence of student achievement – the correct answer – is also unreliable because the student may have known or guessed the answer.
