  • We posit that researchers need to do a better job of researching various contexts of online learning and investigating how the context shapes the experience. We are not arguing as some have that we simply need more experimental or multi-institutional studies with samples in the thousands but rather that we need to do a better job of investigating various and diverse samples of online learning (which then might lead to larger multi-institutional studies).

    1. 1. Prevalence of Convenient Sampling An investigation into sampling trends in online learning research Patrick R. Lowenthal & Ross Perkins Boise State University
    2. 2. Online Growth + million post-secondary students Source: Class Differences: Online Education in the United States, 2010
    3. 3. Poor Quality Research Studies “suffered from weaknesses such as small sample sizes; failure to report retention rates for students in the conditions being contrasted; and, in many cases, potential bias stemming from the authors’ dual roles as experimenters and instructors” (Means et al., 2009, p. xviii) Online learning research is “severely wanting in terms of depth of reporting”
