This article evaluates the use of instructor-created crossword puzzles as a means of reviewing course material. Students completed one crossword puzzle in class to prepare for an exam, and then they had the opportunity to complete a second crossword puzzle outside of class to prepare for the second exam. Students generally rated the crossword puzzle exercise favorably. They described learning more and finding the exercise more helpful for learning concepts and preparing for the exam when completing the crossword puzzle collaboratively in class rather than individually outside of class. Students also rated the exercise higher as a review technique and as more enjoyable when completed in class.
