The figure students already have, brought to life
Students look at the figure in their book and see twenty labels at once. A narrated walkthrough gives them the order: the question the figure answers, each part's job, and how one part leads to the next. Because the video is made on the same figure that's in their book, what they see in class matches what they revise from at home.
Ways teachers use it
- A hook at the start of class: a minute of the heart pumping or the motor turning on the textbook's own drawing, then the discussion.
- Flipped homework: send the video before the lesson so class time goes to questions.
- Absent students: the video covers the figure they missed.
- Mixed-language classes: the same figure explained in English and in Arabic, Urdu, Hindi, Spanish or French, so every student hears it in the language they think in.
- Tutoring: a quick explanation of the exact page your student is stuck on.
Pair it with a quiz
For a lesson that ends with a check, make a lesson video with a quiz on the same topic, or see ContentRoof for teachers. Teachers who sign in with a school email get Pro free.
Fair use of textbook figures
Showing a figure from the class textbook to your own students is everyday teaching. Posting the video publicly is different: use a figure you drew, an openly licensed one, or one the publisher allows you to share.
How it works
- Photograph the figureStraight and in good light, with the figure filling the frame.
- Say what the lesson is about"How the eye focuses light", "Why the water cycle never stops", or leave it empty for the figure's main idea.
- Check the narrationRead the script in the studio and change any line; the video follows. Then download it.
Questions
Is my picture redrawn?
No. The video is made on the exact picture you upload, so every label matches your source. Only the camera, highlights, labels and moving dots are added.
Which languages?
Eleven: English, Arabic, Urdu, Hindi, Spanish, French, Portuguese, German, Italian, Russian and Polish. Narration, captions and labels are in the language you pick, even when the picture is in English.
Can I show it on a projector?
Yes. It's a vertical video; on a projector it plays in the middle of the screen, which suits a single figure well.
Is it free?
You can try it free with a Google sign-in. Students and teachers who sign in with a school email (.edu, .ac.uk, .edu.pk and the like) get ContentRoof Pro free.
