  4. Growing literature documents the promise of active learning instruction in engaging students in college classrooms. Accordingly, faculty professional development (PD) programs on active learning have become increasingly popular in postsecondary institutions; yet, quantitative evidence on the effectiveness of these programs is limited. Using administrative data and an instructor fixed effects approach, we estimate the effect of an active learning PD program on student performance and persistence at a large public institution. Findings indicate that the training improved subsequent persistence in the same field. Using a subset of instructors whose instruction was observed by independent observers, we identify a positive association between training and implementation of active learning teaching practices. These findings provide suggestive evidence that active learning PD has the potential to improve student outcomes.

  5. With the rapid growth of online learning at community colleges and the low course completion and performance associated with it, there has been increasing need to identify effective ways to address the challenges in online teaching and learning at this setting. Based on open-ended survey responses from 105 instructors and 365 students from multiple community colleges in a state, this study examined instructors’ and students’ perceptions of effective and ineffective instructional practices and changes needed in online coursework. By combining structural topic modelling techniques with human coding, we identified instructional practices that were perceived by both instructors and students as effective in supporting online learning as well as ineffective and needing improvement. Moreover, we identified a handful of misalignments between instructors and students in their perceptions of online teaching, including course workload and effective ways to communicate.

    In the past two decades, one of the most important trends in the US higher education system has been the steady increase in distance education through online courses. College administrators have expressed strong support for online education, signaling that the current online expansion will likely continue. While the supply and demand for online higher education is rapidly expanding, questions remain regarding its potential impact on increasing access, reducing costs, and improving student outcomes. Does online education enhance access to higher education among students who would not otherwise enroll in college? Can online courses create savings for students by reducing funding constraints on postsecondary institutions? Will technological innovations improve the quality of online education? This chapter provides a comprehensive review of existing research on online learning’s impact on access, cost, and student performance in higher education. Our review suggests that online education has the potential to expand access to college, especially among adult learners with multiple responsibilities. Yet, the online delivery format imposes additional challenges to effective instruction and learning. Indeed, existing studies on college courses typically find negative effects of online delivery on course outcomes and the online performance decrement is particularly large among academically less-prepared students. As a result, online courses without strong support to students may exacerbate educational inequities. We discuss a handful of practices that could better support students in online courses, including strategic course offering, student counseling, interpersonal interaction, warning and monitoring, and the professional development of faculty. Yet, college administrative data suggests that high-quality online courses with high degrees of instructor interaction and student support cost more to develop and administer than do face-to-face courses.
