Book excerpt: Technology is an increasingly popular part of music education in schools that attracts students to school music who might not otherwise be involved. In many teacher preparation programs, music technology is an afterthought that does not receive the same extensive treatment as do traditional areas of music teaching such as band, orchestra, choir, and general music. This book helps to establish a theoretical and practical foundation for how to teach students to use technology as the major means for developing their musicianship. Including discussions of lesson planning, lesson delivery, and assessment, readers will learn how to gain comfort in the music technology lab. Theory and Practice of Technology-Based Music Instruction also includes "profiles of practice" that dive into the experiences of real teachers in music technology classes, their struggles, their successes, and lessons we can learn from both. In this second edition, new profiles feature Teachers of Color who use technology extensively in their varied types of music teaching. This edition encourages readers to think about issues of inequity of social justice in music education technology and how teachers might begin to address those concerns. Also updated are sections about new standards that may guide music education technology practice, about distance and technology-enhanced learning during the global pandemic, and about ways to integrate technology in emerging contexts.
