Science teachers aiming to foster inquiry in their classrooms will find the sixth title in the Exemplary Science monograph series, The Key to Exemplary Science full of helpful advice and new techniques. The 18 chapters in this monograph illustrate various forms of inquiry, offer detailed examples of planning and execution, and provide case studies highlighting successful implementation of inquiry. Student learning, development of positive attitudes, the ability to use concepts and skills in completely new situations are all demonstrated for use in your classroom. The National Science Education Standards call for every student (every year) to experience the richness and excitement of knowing and understanding the natural world. Editor Robert Yager notes that in one sense, inquiry can be used as a synonym for science. Both include starting with questions, collecting evidence concerning the explanations offered, and arguing with others about the validity of the explanations. Science is a continuing quest for better understanding of the natural universe. This quest is inquiry!
