Our talk with focus on Rederly’s development efforts with CUNY and WeBWorK over the past year. We partner with institutions and the WeBWorK community to develop unique software, built on the WeBWorK platform, that helps address retention, targeted intervention, and online assessment. Our talk will focus on our work with CUNY fellows from 7 institutions to develop OER content, our creation of targeted strategies to identify struggling students and intervene early in major gateway mathematics courses, and our lessons from delivering online final exams to over 2,000 students in the spring.
