This chapter examines English as a Foreign Language (EFL) classrooms in Germany, emphasizing second language (L2) development and feedback through an Intelligent Language Tutorial System (ILTS). Acknowledging the challenges of individualized instruction, the chapter proposes ILTSs as a solution. The focus is on The FeedBook, an ILTS integrated with the EFL syllabus. Results from its implementation phases demonstrate the efficacy of scaffolded feedback, especially for less proficient students. The FeedBook’s potential for inclusive practices, transferability of language gains, and support for implicit learning skills in adolescents are explored. The study contributes to the literature on technology-supported feedback and learner engagement in digitally enhanced language learning. It concludes by calling for continued exploration and development in digitally supported foreign language instruction.
