Getting Started with Direct Measurement Videos

How to use this Website

The heart of this website is the collection of videos. The Video Library contains over 60 videos for teaching introductory mechanics.

Each video is linked to a landing page that displays available file types and provides some ideas for how to teach with that particular video. For example, see this page for How Fast is that? Ice Skaters.

The Activity Library contains classroom-ready activities that incorporate Direct Measurement Videos. These are fully-developed activities that contain the learning goals, student instructions, teaching tips, and assessment ideas.

When students are ready to access the videos themselves, send them to the Student Video Library. This is a directory of video files without links to instructor materials and solutions.

As you plan for integration of Direct Measurement Videos into your teaching, you can learn more about their pedagogic underpinnings. Links from this page describe how the videos contain real data and built-in measurement tools, can engage students in different types of problem-solving, and have many practical applications for teaching mechanics.

Measure the Velocity of a Roller Coaster
This activity can be students' first exposure to using Direct Measurement Videos in physics. Students use a video to make measurements that will allow them to calculate the speed of a roller coaster. This activity will also help students understand the concept of average velocity.


The Direct Measurement Video project has become Pivot Interactives, an educational resources company run by the same dedicated physics teachers who've been developing DMVs since in 2010. We're more committed than ever to bringing powerful teaching tools to students and instructors everywhere.

Our free service on the SERC website will come to an end on June 1, 2018. We invite you to subscribe to Pivot Interactives where you'll find new functionalities. For example, the new learning platform includes integrated, modifiable instructions, data tables with calculated columns, graphing with linear fit, and enhanced grading tools, ...not to mention a boatload of really cool new videos. This integrated platform is far more powerful and effective than videos alone. We hope that if you've had success with DMVs you'll try a free 30-day trial of the new videos and easy-to-use teacher tools.

What teachers say about Pivot Interactives:

"The new Pivot Interactives platform is an impressive leap over just having the videos only. I'll use the new PI platform in my AP Physics class more than I would use the original Direct Measurement Videos alone. " -Alan Calac, Abraham Lincoln High School. San Francisco, California

Pivot Interactives is a game changer. The price is reasonable and you can build a physics curriculum around them. The new tools in Pivot Interactives are wonderful and give more independence to the students. -Tim Taylor, Stratton Mountain School; Stratton, Vermont

"I've made it my official teaching goal this year to replace as many textbook-style homework problems as possible with Pivot exercises. Everything I see on the site is something that makes me say 'wow'. I highly recommend." -Greg Jacobs Woodberry Forest School, Woodberry Forest, VA 22989

My thoughts on Pivot Interactives in perpetuity: Take my money! -Trevor Register, Cherokee County GA
