We are believers in the "open-source" model of educational materials -- use what you need for your students. Please credit our work if you share your materials beyond your own classes, and do not use our materials for commercial purposes. If you modify them (or find bugs), please return the favor by sending us improved materials so we can keep updating. Contact Steven Pollock.

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/  (Link to be updated before summer 2024, stay tuned) 

The links below contain "open" resources (no assessments or solutions).
For those, open the "CU Materials (password protected, for faculty)" block below. 

Our introductory materials were inspired from and originated with Eric Mazur's Peer Instruction book, and expanded at CU by Michael Dubson, Steven Pollock, and many others. NOTE: 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). 
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).

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).
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 contributions. 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.) 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 missing sensitive materials (largely exams and solutions). Please see "CU Materials (password protected for faculty)" further down this page if you are physics faculty and want access to these additional materials)

Modern Physics (sophomore level)

Classical Mechanics/Math Methods 1 (sophomore level)

Quantum Mechanics 1 (junior level) (This is an older collection, following a wave-functions first approach like Griffiths' text)
For more updated QM materials following a spins-first approach, please visit our collections at Physport:

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

Physport.org is an excellent AAPT site with many research based assessments.
Physport has curricular materials:  Open-source curriculum collection
Physport has CU materials for a spins-first Quantum course, and some materials to include  Quantum Information in Quantum classes.
