What? Exercises in which students rank variations of a physical situation on the basis of a specified physical quantity and explain their reasoning. Designed to elicit students' natural ideas about the behavior of physical systems rather than a memorized response, providing insight into their thinking.
Why? Because the tasks are short and independent of one another, they are easy to try out without making significant alterations to your course. They are constructed to be the right "step size" so that students feel comfortable responding to them using their natural ideas rather than memorized physics.
Why not? While the structure and content of ranking tasks are based on physics education research and many are taken directly from the research literature, there is no research on the impact of the final collection on student learning. The books are published commercially so there is a cost for students.
Each exercise consists of four elements:
a place to record the ranking of each variation;
a description of the physical situation, including any constraints and the basis for ranking different arrangements;
a set of figures showing the different arrangements of the situation to be compared;
a place to explain the reason for each ranking choice.
