Improving STEM Education via NLP, Visualization, and Mobile Interfaces

The degree and quality of interaction between students and instructors are critical factors for students’ engagement, retention, and learning outcomes across domains (National Research Council, 2012). Although many suggestions and innovations have been proposed, interactive engagement is still very limited between students and instructors. This is especially true for the introductory Science, Technology, Engineering and Math (STEM) courses at the undergraduate level since these courses are generally taught in lecture halls due to a large number of students enrolled (Mervis, 2013). The larger the class size, the less likely instructors are to employ best teaching practices that foster robust learning such as timely feedback and interactive learning activities (Cuseo, 2007). Recent developments in educational technology (i.e. Massive Open Online Courses, blended learning environments) and financial troubles in universities (i.e. budget cuts by states) make it safe to predict that the class size problem will only get worse both in traditional face-to-face and online classes. So how can we modify the passive nature of lectures and increase the interaction while actively involving both students and instructors in the learning process in these circumstances?

In order to address this problem, we present CourseMIRROR (Mobile In-situ Reflections and Review with Optimized Rubrics), a system that integrates Natural Language Processing (NLP) with a mobile application that prompts students to reflect as well as provide immediate and continuous feedback to instructors about the difficulties that their students encounter. By enhancing the student reflection and instructor feedback cycle with technological tools, this project will incorporate three lines of research: 1) role of students’ reflection and instructor’s feedback on students’ retention and learning outcomes; 2) the effectiveness and reliability of NLP to summarize written responses in a meaningful way; and 3) the value and design of mobile technologies to improve retention and learning in STEM domains.
