Better Learning Through Better Reading and Reflecting part of ACM Pedagogic Resources:ACM Teagle Collegium:Project Reports
Learning from texts is an essential skill for college success, and in an increasingly complex and interconnected world it is ever more important that students develop the intellectual and practical skills for lifelong learning. The aim of this project was to evaluate the impact of reading reflections on student reading, learning, and self-awareness as learners. Students submit reading reflections after completing each reading assignment. These reflections not only encourage students to read more regularly, they also promote content mastery and foster student development of monitoring, self-evaluation, and reflection skills. For the instructor, reading reflections can also be used to facilitate 'just-in-time' teaching. Our results thus far confirm that the introduction of reading reflections in our courses has resulted in significant improvements in student reading and course performance.
