Pearson sought to explore whether the use of MyLab Foundational Skills, a mastery and competency-based online platform designed to assess and remediate a selection of skills to prepare students for college and careers, is related to students' course grades. This Research Report presents findings from two research studies: one comparative study conducted at a community college in the state of Arizona, with students enrolled in Adult Basic Education courses; and one correlational study conducted at Rio Salado College. Correlational study designs were used to seek out possible relationships between the use of MyLab Foundational Skills and students' course grades to identify areas of focus for potential future research using more rigorous causal study designs. The findings appear alongside details of the research studies, including descriptions of the samples studied, methods of analysis, results, limitations and generalizability, and notes on possible future research. The report also summarizes the context surrounding the findings, including the research that informed the design and development of the product, the history of the product in the market, how educators use the product, and its intended outcomes.
