“Teaching Techniques” discusses issues of concern to educators. The primary focus of the column is innovative and interesting approaches to teaching. The standard lecture is a timehonored tradition in academia. It can be an effective and efficient way to convey factual knowledge and key concepts in medical imaging education. However, it is not without shortcomings. A lack of student interaction is an issue in many classrooms. Although instructors may attempt to incorporate activities that promote student interaction into their lectures, students typically assume a passive role in the learning process. The popularity of slideshow presentations has only exacerbated student passiveness in classroom lecturing. Far too often, the classroom experience is reduced to an endless display of slides — each containing long bulleted lists and sentence fragments — simply read aloud by the instructor. Efforts to engage students through discussion or collaborative exercises usually result in a handful of participants taking the lead, while many others remain uninvolved. Medical imaging educators face a considerable challenge in keeping students focused in the classroom, so active learning must be the rule and not the exception.
