Book excerpt: The explosion of digital technologies in the 21st century provided access to multiple robust inquiry, communication, and collaboration applications. The enhanced capabilities provide educational opportunities for engaging students in deeper and more thoughtful learning. Implementation of knowledge-building communities in educational experiences, however, requires new pedagogical strategies that are vastly different from the predominant teacher-directed pedagogies of the 20th century. Today’s teachers now must identify, orchestrate, and manage activities in their content areas in ways that successfully support students through activities such as engagement in knowledge-building communities. Blended Online Learning and Instructional Design for TPACK: Emerging Research and Opportunities is an essential research publication that examines the implementation of knowledge-building communities in educational experiences and pedagogical strategies that encourage engagement. Highlighting topics such as active participation, digital technologies, and online learning, this book is geared toward educators, educational designers, researchers, administrators, and academicians.
