<p>While the benefits of online discussion in education are widely acknowledged, existing research remains fragmented and lacks comprehensive practical guidance. <i>Online Discussion in Secondary and Higher Education: A Complete Guide to Building a Dynamic Online Discourse Community</i> by Yu-Mei Wang, published by Springer in 2024, addresses this gap by offering a systematic and practice-oriented approach to constructing an engaging online discourse community. Grounded in both theoretical and empirical research, the book provides educators with strategies for designing, facilitating, and assessing online discussions. This review summarizes the book’s key contributions and critically examines its strengths and areas for improvement, particularly in balancing its coverage of essential discussion elements, addressing cultural and disciplinary diversity, and exploring emerging technological trends such as AI in online discourse.</p>
