Instructional Design for Task Expertise provides fundamental guidance in designing learner-centered instruction for developing task expertise across educational and training contexts. This textbook is structured into units on defining, designing, developing, and evaluating the instruction. Addressing the field's need for improvement in design process models, the book introduces graduate students, faculty, instructional designers, and learning experience designers to the Holistic 4D Model as a framework through which they can conduct a one-semester ID project in a small team. The authors offer guidance toward integrating key new advancements such as the integration of learner-centered instructional theory with the ID process, holistic design processes and instructional sequences, analysis-design-evaluation cycles, rapid prototyping, and more. Chapters include procedural and heuristic guidance, real-world examples, and activities to help novice and experienced instructional designers better connect theory to practice.
