Respiratory Physiology — Course Overview
About This Course

This course is built differently.

Rather than passively watching videos and hoping things stick, this course walks you through 56 core concepts in respiratory physiology using a structured three-phase process: watch, reflect, and review. Each concept has its own video, reference PDF, and interactive module that will not let you skip ahead without genuinely engaging.

After every concept, your next review date is automatically scheduled using spaced repetition — the most evidence-backed method for long-term retention. Your personal dashboard tracks every concept, shows you what is due today, what is coming up, and what you have mastered. The goal is not to get through the material. It is to own it.

How It Works

Three phases per concept

Phase 1
Watch and Read

The video and your reference PDF load side by side. Watch the full video while following along with the PDF. A timer tracks how long you have been on the page — the Reflect phase does not unlock until you have spent enough time with the material. There is no skipping.

Phase 2
Teach It Back

You will see a prompt asking you to explain the concept in your own words — as if you are teaching it to a friend with no medical background. You must type your explanation. Pasting is disabled. The submit button does not activate until you have written at least 30 words. This is the Feynman Technique: if you cannot explain it simply, you do not know it yet.

Phase 3
See How You Did

Your explanation appears on the right. Your instructor's complete answer appears on the left. Read them side by side. Then work through a short checklist of what a complete explanation must include — check off everything you covered. Your score updates live. Your next review date is automatically set and saved to your dashboard.

What to Expect

Things that are intentional

The timer is real

You cannot click past Phase 1 until you have spent a minimum amount of time watching. The length varies by concept based on video duration. If you need more time, there is an Extend button.

No pasting allowed

The explanation field blocks paste and drag-and-drop. You have to type your answer. This is not a bug — retrieval practice only works when you actually retrieve.

You grade yourself

There is no automated scoring. You compare your explanation to your instructor's and check off what you included. Be honest. The only person you are fooling by checking things you did not say is yourself.

Return visits are different

When you revisit a concept, you will see a welcome screen showing your history and when your next review is due. You can jump straight to the recall phase or rewatch the video first. Your choice.

Getting the Most Out of This

Practical advice

Before you start each session

  • Open the dashboard and check what is due. Prioritize overdue concepts over new ones.
  • Give yourself at least 10-15 minutes per concept — not because the video is long, but because the thinking is.
  • When you write your Feynman explanation, do not just define terms. Explain the mechanism — why things happen, what causes what.
  • When you see your instructor's answer, read it carefully — not just to check your score but to understand what you missed and why.
  • If you scored low on a concept, use the Try Again button right then. A second attempt immediately after seeing the correct answer is one of the most effective learning strategies there is.
