This book provides teachers with practical ways of constructing lessons that will engage students and help them develop personal responsibility for their own learning. State learning standards and related core curricula require students to demonstrate what they know and understand. Students cannot learn to demonstrate their understanding if they sit passively. The authors call for constructivist practices which recognize the important role played by standards and student accountability, and which also acknowledge the practical need for lecture in an appropriate context. This book also shows the links between constructivism and differentiated instruction and other approaches to teaching and learning.
