We are believers in the "open-source" model of educational materials -- use what you need, as you like. We will be delighted if you can use any of these in your courses. If you modify/improve them (or find "bugs"), please return the favor by sending us improved materials so we can keep these links up-to-date and constantly improving. Contact Steven Pollock. And please do reference original sources when it seems appropriate, especially when publishing! We have another (password protected) page with similar resources (but some exams/solutions/etc included), please contact Steven.Pollock (at) Colorado.edu for the password. That page is https://physicscourses.colorado.edu/EducationIssues/cts/secure/  (If the link fails, please cut and paste into your browser)

At the start, many of these materials originally came from Eric Mazur at Harvard (google his "Peer Instruction: A User's Manual" [Prentice Hall] book), and many more were created at CU by Michael Dubson. We now include contributions from other CU faculty. NOTE: Since many originated from Eric Mazur's book on "Peer Instruction", please seek appropriate permission if you want to use those in any public or commercial forum.

Calc based Mechanics materials (35 Meg, zipped folder containing subfolders with concept tests, Tutorial information, syllabus, and more). Materials come from a number of faculty - originally Michael Dubson (with considerable borrowing from Eric Mazur at Harvard!), then Steven Pollock, Bob Wilson at CSU, then smaller updates from Charles Rogers and Murray Holland (who converted some .doc conceptest collections to .ppt format).
Update: Here is a link to Prof. Dubson's latest lecture notes in pdf
Algebra based: Here is a link to Prof. Dubson's latest lecture notes in pdf

Mechanics concept tests ONLY (3 Meg, zipped folder containing concept tests only, largely in .doc formats, but including a first pass at converting some to .ppt).

Calc based Electricity and Magnetism materials (120 Meg, zipped folder containing subfolders with concept tests, Tutorial information, syllabus, and more) Materials come from a number of CU faculty - originally Michael Dubson, then cleaned up by Bob Wilson at CSU, added to by Jamie Nagle and Steven Pollock.
Update: Here is a link to Prof. Dubson's (very complete!). lecture notes in pdf
Algebra based: Here is a link to Prof. Dubson's (very complete!) lecture notes in pdf 

Electricity and Magnetism concept tests ONLY (22 Meg, zipped folder containing concept tests only, in .ppt and .doc formats).
Materials come from a number of CU faculty - originally Michael Dubson, then cleaned up by Bob Wilson at CSU, added to by Jamie Nagle and Steven Pollock.

NOTE: We also have E&M Materials for our algebra-based course (bio/pre med/physiology majors), with solutions. For those, please see our "secure" site. Contact Steven.Pollock (at) colorado.edu for password)  

Energy and the Environment materials. (1.0 Meg, zipped folder containing sub-folders with concept tests, class activities, pre/post tests, and more). Thanks to Tom Murphy at UC San Diego for coming up with a few of the concept questions, this collection is from Steven Pollock.

Physics of Sound and Music for non-majors materials. (36 Meg zipped folder containing sub-folders with concept tests, class activities, pre/post tests, sound files and much more). This collection is from Steven Pollock

Physics of Sound and Music for non-majors concept tests ONLY. (1.2 MB zipped folder containing powerpoint files).
From Steven Pollock

Physics of Light and Color for non-majors (1.3 GB zipped folder containing syllabus, lecture notes, preflight quizzes, project, readings, and resources.)  From Spring 2016, developed by Chasteen, Rogers and Regal. (For the full course materials, including exams and homework, use our "secure" site. Contact Steven.Pollock (at) colorado.edu for password)  

PER-based materials

The collections below are nearly complete, but we have removed some of the more sensitive materials (largely exams and solutions). Please contact Steve Pollock for a password to the more complete collections (with solutions and exams). 

Modern Physics (sophomore level)

Classical Mechanics/Math Methods 1 (sophomore level)

Quantum Mechanics 1 (junior level)

Electricity and Magnetism 1 (junior level, electrostatics)

Electricity and Magnetism 2 (junior level, electrodynamics)

Teaching and Learning Physics (200 Meg, zipped folder containing many course materials) Upper division/graduate course. Materials developed by Noah Finkelstein, with some supplements from Steven Pollock. The folder contains many references and materials from other authors.

Non PER-based materials

Classical Mechanics 2 (134 MB) This is a set of materials developed by Prof. Ethan Neil. (Not associated with a PER project, but a comprehensive followup to the Class Mech 1 materials found above) Secure materials (including exams and solutions) are available through our "secure" page. Contact steven.pollock at colorado.edu for password.

Thermodynamics/statistical mechanics This is a fairly small, zipped folder containing concept tests only. Developed by Michael Dubson, followed up by V. Gurarie and M. Hermele (not as part of any PER project). A very limited set of solutions are available through our "secure" site. Contact Steven.Pollock (at) colorado.edu for password) 

Quantum Mechanics 2 (Fairly small, zipped folder containing concept tests only. (Developed by John Bohn, not as part of any PER project.)

Eric Mazur's Peer Instruction book

STEMclickers Resource Page Part of the Carl Wieman Science Education Initiatives effort to provide resources including written guides and short videos to help instructors start using Clickers and Peer Instruction in classrooms.
