In this chapter the authors discuss the development of children's reading motivation and how motivation contributes to reading engagement. They consider aspects of motivation that may influence children's reading engagement. They review research on how these aspects of motivation develop during the elementary school years, and connect this research to their work on fostering reading engagement in Concept-Oriented Reading Instruction (CORI). They organize the chapter in four sections. First, they define aspects of reading motivation that others and they have assessed. Second, they discuss how motivation links to reading comprehension by influencing the amount of reading that children do. Third, they discuss how children's motivation changes over the school years, and some of the reasons for these changes, including how different kinds of instructional practices influence children's reading motivation. They also present some information in this section about how CORI influences children's reading motivation. Fourth, they discuss their idea that children's intrinsic motivation to read can be enhanced by first creating interest in a topic through hands-on science activities and then connecting this interest to reading. The authors call this the situational-to-general hypothesis. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
