Creating Questions from Learning Objectives (1) E.g. The Learning objective is "Students should be able to use Kirchoff's voltage and current laws to analyze resistive circuits"
Creating Questions from Learning Objectives (2) Q1 A circuit is made of three 1.5V cells as shown.. What current, in Amps, will flow from B to A in this circuit? Could just ask for numeric answer Ans = 4.5/90 = 0.05Amps Then Must make sure it is unambiguous how to answer. e.g 0.05 Amps 0.05 A 5.0 * 10E-2 A mA 30 A C B1.5V
Creating Questions from Learning Objectives (3) For multiple choice, list the answer among some distracters. What would be good distracters? 90/4.5? 90*4.5? 0.5? -0.05? (watch out for this one!)
Working from a past Exam Question Clearly question b is ripe for turning into a multiple choice or numeric answer. What was the point of (the second part) of part a? There are many permutations from this question
Working from known student mistakes Let us assume that students regularly make a mistake with their sums when working out resistance in parallel
12 V 100 ohms 200 ohms 100 ohms 300 ohms A B C I1I1 I2I2 I3I3 I4I4 We could also ask formative questions. 1.What is V AC ? 2.What is resistance of upper loop between A and C? 3.What is I 1 ? 4.What is effective resistance between BC? 5.What is effective resistance of lower loop A to C? 6.What is V AC 7.What is V BC ? 8.What is resistance of upper loop B to C? 9.What is I 3 ? (or we might miss 8 on the basis of 1-3 above) We could ask a straight numeric question such as "What is I 1 ?" "What is I 3 ?" These would be summative questions.
