Asynchronous online discussion boards are an effective tool for developing and enhancing critical thinking skills and writing in online as well as in-person courses. In this teacherready research review, we examine the literature on the benefits of implementing asynchronous online discussion boards as a way of fostering critical thinking and writing skills in psychology courses. We subsequently discuss some of the challenges associated with online discussion boards and offer solutions to address them. One of the primary challenges is the lack of participation or high-level participation of students. To address this challenge, we outline strategies for communicating the purpose and value of the discussion, setting clear expectations for responses, and designing a structure for the discussion. We also review best practices for designing effective question prompts, innovative approaches to discussion questions, and strategies to engage students in the discussion. Sample question prompts for psychology courses as well as a grading rubric for the discussions are provided. Finally, the role of the instructor in facilitating the discussion and techniques for doing so effectively are discussed.
