Mastery learning is one of the most well-evidenced approaches in educational psychology. Yet most students do the opposite — moving to the next topic before fully understanding the current one. Here is why that costs marks.
What mastery learning actually means
Mastery learning, developed by educational psychologist Benjamin Bloom in the 1960s, holds that all students can achieve high levels of learning if given sufficient time and appropriate instruction. Rather than moving an entire class forward on a fixed schedule, mastery learning requires demonstrated competence before progression.
The key word is "demonstrated." Feeling like you understand something is not the same as being able to apply it under exam conditions.
The coverage trap
The pressure to "cover the syllabus" pushes students to race through topics. By the time they reach Paper 2, early topics have faded. Worse, later topics often build on earlier ones — a shaky foundation makes everything harder.
Students who spend an extra week mastering trigonometry before moving on typically outperform those who covered twice as much material at half the depth.
How PeddyLoop implements mastery learning
PeddyLoop tracks mastery at the subtopic level on a five-point scale: Not Started, Beginner, Developing, Proficient, and Mastered. Questions are generated from the same subtopic until mastery is demonstrated, then difficulty increases.
Teachers can see mastery levels across their entire class, making it straightforward to identify who is ready to move on and who needs more time on a specific concept.
