Writing is a challenge and a potential obstacle for students in U.S. 4-year postsecondary institutions lacking prerequisite writing skills. This study aims to address the research question: Is there a relationship between specific features (analytics) in coursework writing and broader success predictors? Knowledge about this relationship could contribute to more immediate personalized learning support for students. To investigate, we collected authentic coursework writing from students enrolled at one of six 4-year colleges. We then extracted natural language processing (NLP) writing features (analytics) from the writing samples and examined relationships between the analytics and college grade point average (GPA). Consistent with Burstein et al. (2017), findings suggest that NLP writing analytics may contribute to college GPA prediction. Our findings imply that real-time NLP writing analytics from authentic coursework writing could be used to efficiently track success and flag potential obstacles during students' college careers.
