This book presents a challenging and multi-faceted research project that required state-of-the-art methodological approaches. The project involved analyzing data collected from 10,000 research articles published in ten leading journals in the area of educational technology over 20 years, from January 1994 to December 2014; advanced analytic approaches such as latent semantic analysis; and expert insights and interpretations of the subject matter. It captures the trends in a number of research streams within the discipline of educational technology and identifies the point in time when a massive change took place. This is a significant achievement given that, in epistemology and philosophy of science, there have always been discussions of paradigm shifts, but researchers have always identified them qualitatively. This is the first work to identify a paradigm shift using rigorous quantitative methods. The analysis procedure involved big data and sophisticated analysis, which supported the identification of clusters at several breakpoints from which the richest set was selected in order to provide the most detailed analysis. This comprehensive analysis also shows what has been published and by whom in those ten top-tier journals. This work makes a highly significant contribution to the field of learning technologies and provides the groundwork and a significant data source for other scholars, both new and experienced, to build on and expand in their work.

The multiple, related fields encompassed by this Major Reference Work represent a convergence of issues and topics germane to the rapidly changing segments of knowledge and practice in educational communications and technology at all levels and around the globe. There is no other comparable work that is designed not only to gather vital, current, and evolving information and understandings in these knowledge segments but also to be updated on a continuing basis in order to keep pace with the rapid changes taking place in the relevant fields. The Handbook is composed of substantive (5,000 to 15,000 words), peer-reviewed entries that examine and explicate seminal facets of learning theory, research, and practice. It provides a broad range of relevant topics, including significant developments as well as innovative uses of technology that promote learning, performance, and instruction. This work is aimed at researchers, designers, developers, instructors, and other professional practitioners.

The purpose of AECT at 100: A Legacy of Leadership is to highlight the Association for Educational Communications and Technology’s 100 years of leadership in educational technology and learning. AECT has a rich history, evolving from the National Education Association’s (NEA) Department of Visual Instruction (DVI) and later the Department of Audio-Visual Instruction (DAVI). Over its 100 years, AECT and its members have had a substantial impact on the evolution of American educational technology and learning, including in the areas of audiovisual instruction, instructional design, and online learning. AECT at 100: A Legacy of Leadership brings together writers and experts in the organization to explore various periods of history within the field and how AECT and its membership stood as a leader within the field. Topics such as visual instruction, the audiovisual movement, leadership development, programmed instruction, diversity leadership, AECT and educational technology topics, journals, ethics, and social justice are explored. Additionally, a number of leaders are explored from the early days of AECT such as James Finn, F. Dean McClusky, Edgar Dale, and Elizabeth Golterman all the way to recent leaders such as Rob Branch.

This contributed volume focuses on understanding the educational strengths and weaknesses of mediated content (including media as a learning supplement), in comparison to traditional face-to-face learning. Each chapter includes research on, and a broad-brush summary of, approaches to combining life sciences education with educational technologies. The chapters are organized into four main sections, each of which focuses on a key question regarding the consequences of incorporating media into education. In this regard, the authors highlight how educational technology is both a bridge and barrier to student access and inclusivity. Further, they address the ongoing discussion as to whether students need to be present for lectures, and on how having agency in their own learning can improve both retention and conceptual understanding. To link the content to current events, the authors also shed light on the impact that the COVID-19 pandemic is having on the continuity of educational programs and on the growing importance of educational technologies. Consequently, the book offers life science educators valuable guidance on the technologies already available, and an outlook on what is yet to come.

This edition of this handbook updates and expands its review of the research, theory, issues and methodology that constitute the field of educational communications and technology. Organized into seven sectors, it profiles and integrates the following elements of this rapidly changing field.
