This volume is an attempt to articulate a taxonomy of educational objectives that uses the best available research and theory accumulated since the publication of the taxonomy of educational objectives of B. Bloom and others in 1956. Like Bloom's taxonomy, this taxonomy defines six levels of mental processing: self-system thinking (Level 6); metacognition (Level 5); knowledge utilization (Level 4); analysis (Level 3); comprehension (Level 2); and retrieval (level 1). The first chapter discusses the work of Bloom and his colleagues, and the second chapter contains a general model of human decision making and information processing as the foundation of the "New Taxonomy." Chapter 3 describes three knowledge domains, and chapter 4 provides the theoretical and research backgrounds for the three systems of thought. Chapter 5 contains examples of learning objectives across all six levels of the new taxonomy, and chapter 6 discusses the ways educators might use the new taxonomy. (Contains 50 figures and 170 references.) (SLD)
