University Of Colorado Boulder Physics Research Paper


The Physics Education Research group in the Department of Physics engages in both theoretical and experimental work to understand student learning in physics and the conditions which support (and inhibit) student learning. While we focus largely at the university undergraduate level, we have research projects that span the K-Grad and teacher professional development

Physics Education Research @ Colorado

The Physics Education Research Group at Colorado (PER@C) group is one of the newest and largest research programs in PER in the nation. The PER@C research group develops and studies: uses of technology in physics education, assessments (conceptual, epistemological, and belief oriented), curricular and classroom materials at the middle- and upper-division levels, theoretical models of students learning physics, social and contextual foundations of student learning, examination of successful educational reforms and replication studies of such reforms, and student problem-solving in physics. The research group includes faculty, staff, and students from both the Department of Physics and the School of Education. PER@C sponsors a number of educational reforms in physics, which range from pre-college to post-doctoral.

Comprehensive Exam Overview

Comprehensive Exams (or Comps) are considered fundamental stepping stones to attaining an advanced degree. In the Department of Physics, there are three levels of Comps.  A Ph.D. candidate must complete all three plus a dissertation defense in order to graduate. A master's degree requires that only Comps I and Comps II are satisfied (and possibly a thesis defense).

Recommended Timeline:

  • Years 1 – 2: Comps I satisfied

  • Year 3: Comps II satisfied

  • Year 4 – 5: Comps III satisfied

Comps I

Comps I is satisfied by sucessfully completing five of the six courses below with a grade of B– or better:

  • Quantum Mechanics (PHYS5250 and PHYS5260)
  • Electromagnetic Theory (PHYS7310 and PHYS7320)
  • Statistical Mechanics (PHYS7230)
  • Theoretical Mechanics (PHYS5210)

These requirements may be different for students in the Chemical Physics program, Geophysics program, Applied Physics certificate, IQBio certificate, etc.  If you have taken courses at the graduate level that may be equivalent to those listed, you may be able to get these courses waived by completing the Comps Course Waiver Request.

Comps II Overview

Candidates are expected to take the Comps II examination within one year of completing Comps I and no later than their sixth enrolled semester. Comps II consists of the preparation of a formal paper that summarizes a broad research topic. The student then delivers an oral presentation about the content of the research paper, and undergoes an oral examination on the research topic as well as his/her general knowledge of physics. For more information, please review the Comprehensive Exam Process Guide for Students.

Paperwork and Deadlines

Prior to the exam, the student is expected to print and complete the following forms, and bring the forms with him/her to the presentation and oral examination.

Graduate students who have not taken Comps II by the end of their sixth enrolled regular semester are considered to have failed Comps II and may not remain in the program. A student who fails a first attempt in the semester before the deadline, or needs to retake any part of the exam, may continue through the following regular semester to allow time to complete the exam process. Retakes in the fall semester must be completed by September 30.

Scheduling the Exam

If the candidate wants to use Comps II as a Master's exam, which the department encourages, it must be taken during a term when the student is registered. Normally, this means Fall, Spring, or Maymester. The exam must be completed before the first day of classes for Summer session. In Fall, two weeks prior to the start of classes also counts as Fall term. If Comps II is taken during the summer and the student is not registered for courses, the exam may NOT be used to obtain a master’s degree.

Comps III Overview

Comps III is preparation for a student’s doctoral thesis. The exam consists of two parts. The first part is the thesis proposal. Students should work with their advisor on content and length. The second part involves the presentation of the proposal to the thesis committee. The student must demonstrate his/her knowledge of the thesis subject before a committee of five qualified faculty members.

For Comps III, each student should follow the guidelines below to choose a five-member thesis committee, although only three are required to attend the Comps III exam. Please note: all five committee members must sign the exam form. Students should meet with their entire committee at least once a year. Then, when the student is ready to defend, four of these members will serve on the defense committee along with an outside member. All committee members must be on the graduate faculty. However, a researcher does not need to be a faculty member to have a graduate faculty appointment. Please see the Graduate Program Assistant for a current list of graduate faculty members.

A student must be registered as full time during the semester in which the Comps III exam will be taken.

Selecting a Committee

A student's committee is comprised of five graduate faculty members. There must be at least three physicists on the committee. One or two members may come from other departments, but this is optional. All five members may be from the Physics Department. The following are specific requirements for students in special circumstances:

Students working for professors outside physics:
  • Research advisor (non-physics faculty member)
  • Titular advisor (member of the physics faculty): this is the person with whom you'll enroll for dissertation hours. His/her research should be related to your own. Ask your research advisor for suggestions. See the Graduate Assistant for help.
  • Three additional graduate faculty members: only one of these may be from outside the physics department.
Students working off-campus:
  • Research advisor (NCAR, NIST, NOAA, NREL, etc.): has a graduate faculty appointment in physics but may not chair committee.
  • Titular advisor (member of physics faculty): this is the person with whom you'll enroll for dissertation hours. His/her research should be related to your own. Ask your research advisor for suggestions. See the Graduate Assistant for help.
  • Three additonal graduate faculty members: two of these may be from outside the physics department, meaning their grad faculty appointment is not in physics.

The guidelines above were agreed upon by the Department Chair and the Associate Chair of Graduate Studies. To deviate from these guidelines, you must petition the Associate Chair of Graduate Studies in writing.

Paperwork and Deadlines

Prior to the exam, the candidate is expected to prepare and submit the following documents:

  1. Comps III Examination Report Form (.pdf) (.doc) - Please download, complete and submit the unsigned form 2 weeks before the exam. The exam committee must then sign the form upon completion of the exam. The pay rate for RAs is greater for students that have completed Comps III (currently $133 more per month).  To ensure you receive the correct pay, please submit a copy of the signed form to whoever handles your RA pay.
  2. Candidacy Application - Please download and complete the entire form with all necessary signatures. Candidacy Applications are due the day of the Comps III exam.

Dissertation Defense

The dissertation defense is similar to the Comps III examination.  A committee of at least 5 members should be chosen following the rules for the Comps III committee with the added requirement that one of the members of the committee must be a regular CU Boulder faculty member from a department other than physics.
