Modular instruction is an approach that divides course content into independent, self-contained units called modules. Each module focuses on well-defined learning objectives and allows students to work through material at their own pace. The modular approach aims to make education more individualized and adaptable to large class sizes. While modular courses have been successfully implemented in many universities, some challenges can arise in areas like student experience, instructor roles, and administration. Overall, modular instruction's emphasis on self-paced learning makes it a promising alternative for higher education.
