With its problem-oriented approach to instructional design, the third edition of The ID CaseBook provides 32 realistic case studies in a wide range of authentic contexts, from K-12 to post-secondary, corporate, and military. The cases and their accompanying discussion questions encourage students to analyze the available information, develop conclusions, and consider alternative possibilities in resolving ID problems. Features of the Third Edition include: NEW! Nine cases have been added, increasing the variety of contents, contexts, and audiences encompassed by the text. NEW! Case matrix on the inside front cover allows you to quickly identify which cases are most appropriate for your course. Preliminary Analysis Questions in each case stimulate readersrs" thinking by asking them to discuss the relevant issues, consider the situation from multiple perspectives, develop a solution, and foresee the possible resulting consequences. Implications for ID Practice in each case encourage readers to expand their thinking on the case issues, from theoretical and practical viewpoints of instructional design. Praise for the Second Edition: "What the ID CaseBook does is give our students more experiences than they could possibly cram into a course or semester. Through the cases they visit schools, companies, and government agencies. They see people grappling well, and often not so well, with realistic challenges. It's a very useful resource." -- Allison Rossett, San Diego State University "The cases in the ID CaseBook replicate real ID and performance problems, as well as promote multiple viewpoints and learning outcomes. In my experience, with several learner populations, the biggest benefit has been in uncovering learnersrs" implicit world-views." -- Kathleen W. Ingram, Logistics Services International, Inc. The ID CaseBook is extremely effective in engaging students in my online instructional design courses through directed group discussions of the excellent case learning situations. -- Sallie J. Johnson, Troy University The second edition of the ID CaseBook received the 2002 award for Outstanding Book in the Field of Instructional Design from the Association of Educational Communications and Technology.
