"Teaching and Measuring Cognitive Readiness" is a comprehensive textbook that addresses the theoretical and empirical aspects of cognitive readiness. It examines how this readiness affects the learning ability of adults and the role it plays in various contexts, such as education, the military, and industry. The term "readiness" is used in this context to assess learners' preparation in K-12 schools as well as their effectiveness in task execution. The book views cognitive readiness through the lens of knowledge, skills, and attributes (KSA) and provides valuable insights into the need for teaching and assessment strategies based on cognitive readiness. It also emphasizes the integration of assessments into training for cognitive readiness and the importance of theory-driven evaluation studies to enhance knowledge and effectiveness in teaching.
