This book focuses on English as a Foreign Language (EFL) and provides advice on how to approach EFL teaching in the online context. Coronavirus has accelerated e-learning significantly and has highlighted the need of appropriate web tools that will allow teachers to present their material either synchronously or asynchronously, while also adequately assess their students. At the same time, there is a need of tools that can engage the students and motivate them to actively participate in the lesson. With e-learning being a rather new challenge for both teachers and students, this book provides research- and practice- based chapters with strategies, techniques, approaches, and methods which have proven to be successful in e-learning environments, maximizing their impact. Apart from presenting research results with strong pedagogical implications on online or blended English language learning and teaching, the book also trains educators on utilizing online tools and managing online learning environments and platforms.
