What Is a Flipped Classroom and How Does It Work?

Updated

A flipped classroom moves direct instruction out of class time and into individual study, usually through short videos, then uses class time for practice, discussion, and problem-solving with the teacher available. It fits courses where students can access videos outside class and where class time is more valuable for guided practice than for lecture. flippedmath.com describes this model as "flipped-mastery," where students demonstrate mastery of each concept and progress at their own pace.

The core idea

In a traditional class, the teacher explains new material during class and students practice at home. In a flipped classroom, that order reverses:

  • Before class: students watch a video or read a lesson to meet the concept for the first time.
  • During class: students work problems, ask questions, and get direct help while the teacher circulates.
  • After class: students continue practice or move to the next concept.

The point is not the video itself. The point is what the freed-up class time makes possible: more individual attention, more active work, and faster feedback on mistakes.

Flipped classroom vs. flipped-mastery

These terms are related but not identical.

Dimension Flipped classroom Flipped-mastery
Pace Whole class generally moves together Each student moves at their own pace
Progression Advance after the class covers a topic Advance only after demonstrating mastery of each concept
Class time Practice and teacher support Practice, assessment, and re-teaching as needed
Main risk Students skip the pre-class work Students stall or need strong progress tracking

flippedmath.com states that its flipped-mastery approach "allows students to demonstrate mastery of all concepts and progress at their individual pace," covering Algebra, Geometry, Algebra 2, Pre-Calc, and Calculus. That is a stronger commitment than simply flipping a single lesson: it changes how the course is organized, graded, and paced.

How to set up a flipped classroom

  1. Choose or record the pre-class material. Keep videos short and focused on one concept. flippedmath.com organizes courses by subject and topic, so a teacher can assign an existing lesson instead of building everything from scratch.
  2. Tell students exactly what to do before class. A vague "watch the video" leads to low completion. Specify the video, a note-taking task, and one or two check questions.
  3. Check pre-class learning at the start of class. A short quiz, a warm-up problem, or a quick review of notes tells you who is ready and who is not.
  4. Design class time around active work. Use problem sets, group tasks, stations, or one-on-one help. If class time becomes another lecture, the flip has no purpose.
  5. Build in a way to verify mastery. In a flipped-mastery course, students should not move on until they can show they understand the concept. flippedmath.com's model uses mastery checks as the gate for progress.
  6. Plan for students who are not ready. Have a backup task or a re-teach path for students who did not complete or did not understand the pre-class work.

Common challenges and what to do about them

  • Students do not complete the pre-class work. Use a short accountability check at the start of class, and keep videos short enough that completion is realistic.
  • Limited device or internet access. Provide downloadable videos, printed notes, or in-class viewing time for students who cannot watch at home.
  • Class activities fall flat. Match the activity to the concept: procedural topics may need worked examples and practice, while conceptual topics may need discussion or application tasks.
  • Students move too slowly in a mastery model. Track progress visibly and set checkpoints so students do not stall indefinitely.

Is it right for your course?

A flipped classroom tends to work well when:

  • The subject has clear, sequenced concepts that can be introduced in short videos.
  • Students can access the pre-class material outside class.
  • Class time is more useful for practice and feedback than for lecture.
  • The teacher is willing to redesign class activities, not just record videos.

It tends to be harder when students have unreliable access to technology, when the material depends heavily on live demonstration, or when the teacher cannot monitor pre-class completion. The flipped-mastery version adds a further requirement: a workable system for tracking each student's progress and mastery, which is more demanding than flipping a single unit.

For a concrete example of the model in practice, flippedmath.com provides courses, pacing guides, and explanations of how flipped-mastery works, along with teacher and parent FAQs, so you can see how the structure is applied across Algebra, Geometry, Algebra 2, Pre-Calculus, and Calculus.
