In creating crossword puzzles themselves, students gain an understanding of a concept in order to create the clue for it. The instructor can make this activity either chapter- or domain-specific, for instance, to encourage reading the textbook and researching concepts. In this unique application of the self-generated crossword, students use free internet programs to easily create these puzzles and bring copies of their completed crosswords to class so their peers can solve them. This highly interactive exercise provides a unique opportunity for students to engage with the material and to participate in the classroom.
