In the junior and senior year, generally, students will complete the CI subjects within their major department. These classes are called CI-M (Communication Intensive in the Major). CI-Ms are integral to each major program and teach the specific forms of written, oral, and/or visual communication appropriate to the field's professional and academic culture. Students may write in teams; prepare and present oral and visual research reports for different audiences; learn audience analysis and peer review; or go through the experience of proposing, writing, and extensively revising a professional journal article. Students must pass the CI-M subject in order to receive credit, however, they may receive credit for more than one CI-M per term or for both a CI-H and a CI-M taken in the same term.

The Department of Physics has designated the following subjects as CI-M:

VIII and VIII-A options:
8.06 Quantum Physics III
8.13 Experimental Physics I

VIII-Flexible Option (formally VIII-B):
The Physics Department recommends that VIII-Flexible options students satisfy the departmental portion of the Communications Requirement by taking 8.13 and either 8.225J or 8.287J. The department may accept substitutions for these subjects by CI-M subjects from other departments if they form a natural part of the student's individual program.
