The identification of the contextual elements of a question is important. Based on our studies on the possible student mental models on certain concepts in electricity and magnetism, a set of multiple-choice questions were developed and tested. Examples of test questions and students' responses on one concept topic are discussed in detail. It is implied that measurement instruments developed based on a good understanding of the interactive relations between context features and the possible mental models can help identify important aspects of students' knowledge that are not available with current assessment tools.
