Question type: Matching question (Labelling)
Description: A matching question essentially presents two lists of items and requires the student to match one item from the first list to an item from the second. Matching questions are very versatile and can be used to present a broad range of exercises. They can also use three different ways of interacting with the computer. The example below (drag and drop) requires the diagrams (images) to be matched to the box corrsponnding to the appropriate stage of rotation, by dragging and dropping the images in the boxes.
Matching Items - Another form of multiple choice
* Good means to assess content knowledge; can move to application by asking students to match concepts to
examples of them, causes with likely effects, etc
* Easier to write than multiple choice since distracters are unnecessary
* More efficient than multiple choice because students need to read only one set of options to answer several items
* May be difficult to come up with plausible, differentiated options
* Absence of distracters makes it harder to know where students are confused
* More potential for correct guesses than in multiple choice
Advice on Writing Matching Questions
* Every option in answer group should be a plausible answer to every item or question
* Limit the number of matching items to 10-15
* Allow each option to be used more than once or not at all. Perfect matches aid test savvy students and hurt those who misunderstand one item
* Give clear directions. Explain how the two columns are related, and that some options may be used more than once or not at all.
* Make it easy for students who understand to find the right answer by limiting answers to single words or short phrases. Limit longer statements to the “questions.”
Question: The figure below is an illustration of a cross-section section through an ampulla in the semi-circular canal.
This vestibular structure is responsible for detecting angular (rotational) acceleration. Within the ampulla is a gelatinous mass, ‘the cupula’, which contains hair-like processes. This is attached at the base, but ‘floats’ in endolymph fluid, which is said to have ‘inertia’ (ie. it resists changes in motion). Spinning will generate angular/rotational acceleration, which will result in the apparent direction of endolymph flow going in the opposite direction, displacing the cupula and causing action potentials being fired.
Note: It takes approximately 15-30 seconds for the endolymph fluid to ‘catch-up’ with the semi-circular canal’s rate of movement.
Given this information, imagine that a subject spins around in the same direction for 15-30 seconds before coming to an abrupt halt. Look at the four diagrams below. Each one represents the state of the cupula relative to the ampulla at a different stage during this rotation. The red arrow indicates the direction in which the semi-circular canal is rotating; the blue arrow indicates the 'relative' direction of the endolymph fluid.
Click on each of these diagrams and ‘drag and drop’ them into the box corresponding to the appropriate stage of rotation.
