Following the integration of an online homework tool -- MyEnglishLab (MEL) -- into their English courseware products, Pearson sought to explore how one of these products, Top Notch, was being implemented with MyEnglishLab and perceptions about the impact it was having on learning. Top Notch is a six-level communicative course that aims to help adults and young adults build the communication skills and self-confidence needed to navigate social, travel, academic, and business situations in English. This Research Report presents findings from three research studies Pearson completed between 2016 and 2017 that focused on the implementation of Top Notch with MEL. Studies were completed with three institutions in Colombia, three institutions in Mexico, and two institutions in Peru. The institutions were selected purposefully based on whether they were using the full package and latest version of Top Notch with MEL. An implementation study design was chosen in each case to understand the range of students' and teachers' experiences using Top Notch with MEL and to evaluate their perceptions about the impact of using the product on access and experience, achievement and progression outcomes. The findings included in this report are only a sample of the overall findings. The studies collected and analysed a broad range of evidence, including teacher surveys and interviews, student surveys and MEL performance data. 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 summarises 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.
