Meet the meta-analysis cohort

The second cohort of the research seminars program will apply the technique of meta-analysis to synthesize research studies in online education. Meta-analysis is set of procedures that are used to combine and compare the results of multiple studies on a particular topic. The goal of meta-analysis is to statistically combine the data from selected studies to determine if there is an overall effect and assess the magnitude of the effect. As online/distance education has grown in the past 20 years, meta-analysis has been applied to some of the most fundamental questions in the field. There is an ongoing need to use meta-analytic techniques to better synthesize the research in the area of online teaching and learning. Administrators, faculty and staff continue to ask questions about the effectiveness of online and hybrid education, emerging tools and technologies related to online learning and various pedagogical approaches. Meta-analysis has the potential to suggest answers to these questions.
