While grammar instruction remains a central component of many writing courses, relatively few studies have examined how specific grammar components relate to writing improvement, learner developmental trajectories, and instructional priorities within a single classroom dataset.Purpose: This study investigated writing development across drafts, the predictive role of grammar quiz components, learner clustering, and tiered instructional priorities in a university-level practical writing course.Method: Participants were 21 Korean university students enrolled in a Fall 2018 practical writing course. The dataset included pre- and post-draft writing scores and five grammar quiz components: sentence types, agreement, main verb usage, parallelism, and articles. Analyses included a paired-samples t-test, multiple regression, k-means cluster analysis, and instructional priority analysis.\u003c\/p\u003e","brand":"LAP Lambert Academic Publishing","offers":[{"title":"Paperback","offer_id":47883637260439,"sku":"9786209896934","price":11104.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9786209896934.webp?v=1781103004","url":"https:\/\/atlanticbooks.com\/products\/automated-written-corrective-feedback-19-21-9786209896934","provider":"Atlantic Books","version":"1.0","type":"link"}
