Modular teaching involves breaking course content into discrete, self-contained units called modules. Modules cover a single or group of related learning objectives and include varied learning activities, self-assessment, and an evaluation component. Modules allow students to learn at their own pace and receive immediate feedback. Some key advantages include flexibility, self-paced learning, and assessing mastery of individual objectives rather than overall grades. While effective for many students, modular teaching requires appropriate resources and may not be suitable for all learners.
