RESUMO
As medical students search for ways to squeeze more hours of learning into their day, many have turned to technology for quick and efficient ways to study. Most commonly this includes based apps for purchase that involve visual tasks, mental review and repetition. Tasks involve flashcard creation, answering multiple choice questions (MCQs) and schedule planning. They typically require students to visually interact with a computer or smartphone screen. Alternatively, auditory apps may not only offer the benefit of enhanced learning through review and repetition, but also address convenience, portability, and metacognitive development without physical and temporal requirements of visual presentation. Auditory learning is eyes and "hands-free" allowing the learner to contiguously engage in other activities such as physical exercise, traveling, eating, etc. In this randomized, case-comparison study, half of the students were exposed to audio lecture content before class using a mobile application called LectureKeepr (LK) and half were exposed to lecture content before class via written material prepared by the professor. Pre- and post-MCQ quizzes were used to measure differences between groups in knowledge improvement. In addition, student perceptions of the auditory learning experience were assessed by an on-line survey. ANOVA with repeated measures revealed that students in the LK intervention group performed better on the postquiz than the students in the written materials group.
