Crossword puzzles: self-learning tool in pharmacology

Students of the second professional MBBS course of the Indian medical curriculum (II MBBS) perceive pharmacology as a ‘Volatile Subject’ because they often find it difficult to remember and recall drug names. We evaluated the usefulness of crossword puzzles as a self-learning tool to help pharmacology students to remember drug names. We also measured the students’ satisfaction with this learning method. This was an open-label randomized, two-arm intervention study, conducted with II MBBS students (n = 70), randomly selected and assigned to two groups A (n = 35) and B (n = 35). Two self-learning modules containing crossword puzzles with antihypertensive and antiepileptic drug terms were prepared and pre-validated. Hard copies of both crossword puzzles were administered to Group A (Intervention group) on two different occasions. One hour was allotted to solve a puzzle. Students were allowed to refer to their textbooks. Group B (Control group) underwent the self-learning module without the crossword puzzles. In both groups, pre- and post-test knowledge was assessed. Students’ perceptions of the crossword puzzles were assessed using a pre-validated 10-item questionnaire. Responses to items 1–8 were recorded using a 5-point Likert scale. Responses to item 9 were recorded on a 10-point rating scale while item 10 was an open–ended question. The crossword completion index was 92.86 %.
