“…The importance of grammatical and structural errors can be seen clearly in writing assessment literature which highlights the importance of these errors in explaining writing quality (Eckes, 2008;Santos, 1988;Zhu, 2003), teaching these rules to students (Graham, 1983;Morris, Blanton, L. Blanton, W., & Perney, 1995), and teacher beliefs about the importance of these rules (Cutler & Graham, 2008). Additionally, structural and mechanical rules are important components of writing across a variety of disciplines and fields including business, engineering (Zhu, 2003), editing, and journalism (Ward & Seifert, 1990) One problem with assessing the importance of structural and mechanical errors in writing is that coding such errors is time intensive, subjective, and prone to inaccuracies. While a number of systems are available that assess structural and mechanical in student writing such as Ginger, Grammarly, and Whitesmoke, these systems are meant to provide automated written corrective feedback to writers (Ranalli, Link, & Chukharev-Hudilainen, 2017) and are not designed for research purposes.…”
