When led effectively, inquiry-based instruction leads to higher order thinking. Developing, Assessing, and Sustaining Inquiry-Based Instruction is a practical book that presents a clear, research-based guide to help teachers and other educational leaders dramatically improve their practice and, ultimately, increase student achievement. The authors have given teachers and educational leaders down-to-earth assistance that realistically merges theory and practice. Specifically, they provide a well-tested model for inquiry, a web tool that frames the development and implementation of inquiry-based lessons, and an instrument to assess the quality of inquiry. In addition, the authors present suggestions for incremental change with realistic targets, and they deal head-on with issues of classroom management and the resistance that often arises when trying to implement meaningful change. This book is a must for teachers and educational leaders who expect excellence in their teaching performance and in student achievement.
