Changes Underway on the Direct Measurement Video Website

Since 2012 we have been able to support the Direct Measurement Video project by volunteering our time and by attracting some limited grant funding. Unfortunately this model can not support the project in the long term, much less allow us to realize the educational possibilities that we imagine for interactive video. For that reason we have begun charging a small per-student fee.

Our new educational effort is called Pivot Interactives. The new Pivot Interactives website offers a powerful platform for students to learn science concepts and science process skills. It contains classroom-ready activities with integrated data tables and graphing capabilities, teacher-modifiable student instructions, and allows teachers to create classes to assign and grade student work. In addition, the platform features more video arrays with the Pivot Player interactive tools, and a user-interface that allows users to change variables within the videos, such as the mass of objects or frequency of a wave.

Here are the changes underway:

  • During late summer and fall 2017, many of the videos on the Direct Measurement Video website will be migrated to the Pivot Interactives site and will no longer be freely available. 

  • While we would love to be able to offer all of the latest material for free, a subscription-based service will allow us to continue to improve our offerings and maintain the project so that it remains here for you year after year. 

As we migrate to a subscription-based service, we are aiming for a cost that is reasonable for teachers while allowing us to continue to develop high-quality videos and interactive instructional tools.

  • Free, 30-day trial accounts are available.
  • For high schools, subscriptions start at $150 per year, which includes up to 30 student licenses. Additional licenses are $5 per student.
  • For colleges, subscriptions start at $300 per semester, which includes up to 30 student licenses. Additional licenses are $10 per student.
Subscriptions and free trials are both available through the Vernier website.

We'd love to hear feedback from you at

Thank you,

Teacher's Note:

The student video library provides student access to all videos without links to instructor materials and solutions.

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
