This series, which prepares for the "English Summary Problem" and "English Composition Problem" that account for a large weighting in the Eiken first-stage examination, is an innovative teaching material that aims for success by building true "writing" ability without relying on rote memorization, through step-by-step learning: "short essay writing → 1-sentence summary → practical summary/essay writing."
"Recipe" provides technology for Chapter 4 "English Composition Problems" (practical English writing training) in each book of this series. By scanning handwritten English compositions with the app, learners receive real-time AI-powered essay correction results and "feedback for better English sentences." In addition to pointing out grammatical errors, unnatural vocabulary usage, and proposing revisions for more "Eiken-like" sophisticated expressions, scores are calculated on a 5-level scale (S-D) across four aspects: content, composition, vocabulary, and grammar, allowing learners to visualize their writing proficiency.
Handwritten English compositions filled out on special answer sheets can be scanned and corrected with "Recipe."
Overall writing scores, vocabulary and grammar corrections, feedback for "better English," and model answers are provided instantly.
Furthermore, purchasers of this book series can also enjoy a 1-month free trial of "Recipe"'s "Standard Plan." This campaign encourages users to experience "cutting-edge English learning" through the app, starting with Eiken preparation.
*This campaign may end without prior notice.
This collaboration between "Recipe" and Gakken's books proposes a completely new learning style, ideally merging the "best of both" book-based learning and technology.
"Recipe" will continue to connect "technology and people," offering advanced English education.
