Creating Effective Online Quizzes and Exams

Multiple choice test questions, also known as items, can be an effective and efficient way to assess learning outcomes. Multiple choice test items have several potential advantages:

Versatility: Multiple choice test items can be written to assess various levels of learning outcomes, from basic recall to application, analysis, and evaluation. Because students are choosing from a set of potential answers, however, there are obvious limits on what can be tested with multiple choice items. For example, they are not an effective way to test students’ ability to organize thoughts or articulate explanations or creative ideas.

Reliability: Reliability is defined as the degree to which a test consistently measures a learning outcome. Multiple choice test items are less susceptible to guessing than true/false questions, making them a more reliable means of assessment. The reliability is enhanced when the number of MC items focused on a single learning objective is increased. In addition, the objective scoring associated with multiple choice test items frees them from problems with scorer inconsistency that can plague scoring of essay questions.

Validity: Validity is the degree to which a test measures the learning outcomes it purports to measure. Because students can typically answer a multiple choice item much more quickly than an essay question, tests based on multiple choice items can typically focus on a relatively broad representation of course material, thus increasing the validity of the assessment.

The key to taking advantage of these strengths, however, is construction of good multiple choice items.

A multiple choice item consists of a problem, known as the stem, and a list of suggested solutions, known as alternatives. The alternatives consist of one correct or best alternative, which is the answer, and incorrect or inferior alternatives, known as distractors.  Before designing an online quiz, instructors must first determine if it will assess lower- order thinking skills in order to check for comprehension, or higher-order thinking skills in order to check for application and synthesis.
