Mastery learning is an instructional strategy that ensures students master objectives at their own pace. It involves designing instructional materials to sequence objectives, delivering instruction, and allowing students to demonstrate mastery through assessments before moving on. The approach was influenced by Benjamin Bloom's taxonomy of educational objectives and Robert Gagne's theory of prerequisite skills. When implemented properly with technologies like video podcasting and online discussions, mastery learning can benefit all students in achieving an in-depth understanding of course material.
