TY - CHAP TI - Data Mining Large-Scale Formative Writing AU - Foltz, Peter AU - Rosenstein, Mark T2 - The Handbook of Learning Analytics A2 - Lang, Charles A2 - Siemens, George A2 - Wise, Alyssa Friend A2 - GaĊĦevic, Dragan AB - Student writing in digital educational environments can provide a wealth of information about the processes involved in learning to write as well as evidence for the impact of the digital environment on those processes. Developing writing skills is highly dependent on students having opportunities to practice, most particularly when they are supported with frequent feedback and are taught strategies for planning, revising, and editing their compositions. Formative systems incorporating automated writing scoring provide the opportunities for students to write, receive feedback, and then revise essays in a timely iterative cycle. This chapter provides an analysis of a large-scale formative writing system using over a million student essays written in response to several hundred pre-de ned prompts used to improve educational outcomes, better understand the role of feedback in writing, drive improvements in formative technology, and design better kinds of feedback and scaffolding to support students in the writing process.
