This astrophysics research is intended to use methods of spectroscopy to measure the redshift of quasar 3C 273. This tendency of the spectra of quasars to be redshifted is important because it indicates that these bodies are receding from Earth at rates proportional to their distance. This is an important indicator of the expansion of the universe. After collecting this data, we hope that a physics laboratory experiment to perform measurements like this can be developed at Saginaw Valley State University.

Join us in exploring emergent themes in PER as a scholarly endeavor and as a research community!  Since its inception, PER has served as a confluence of discipline, theory, research methodology, practice, and application.  How have these facets and the interplays among them been fruitful for physics education globally, regionally, locally, or otherwise?  And, how have our successes and interactions influenced the very nature of PER itself?
Following the lead of AAPT for the summer meeting, PERC 20/20 was virtual. Enjoy browsing the content.

The 2020 AAPT Virtual Summer Meeting brought together physics educators from around the globe to learn about the latest in physics theory, research methodology and education from leaders in their field. 

As part of a larger study of exploring students’ problem solving in small groups, we investigated how an instructor influences students’ epistemic framing in an upper-division electromagnetism class. We use the CAMP (Conceptual, Algorithmic, Mathematics, Physics) framework to investigate the dynamics of students’ frames
surrounding their interaction with the instructor, tracking frame triplets before, during and after the instructor’s intervention during tutorial sessions. We present a case study of one such triplet (AP, CP, AP) by qualitatively analyzing student interaction with the instructor. Careful examination indicates that disagreements during the interaction necessitated the instructor to initiate conceptual discussion thereby causing a frame shift from an algorithmic to a conceptual frame.
