While enrollment and retention figures often grab headlines for Massively Open Online Courses (MOOCs), the more telling measures of MOOCs' effectiveness may be found in the educational outcomes. The performance of students enrolled in the University of Colorado Physics I MOOC was evaluated with the use of numerous instruments. These instruments include exams, homework assignments, the FMCE and the CLASS. The performance of students in the MOOC was tracked across the semester and compared with that of students in similar "Brick and Mortar" classes at the University of Colorado. For some measures (FMCE) their performance was compared with the results from large scale studies. On all measures the MOOC students performed at least as well as and had learning gains at least as great as those in more traditional settings including interactive engagement. This may be due, in part, to a massive self-selection process skewing the MOOC population over time.
