This study examined the alignment of three selected U.S. high school textbooks series with the Common Core State Standards for Mathematics (CCSSM) regarding the treatment of statistical association. A framework grounded in the literature for inclusion and exclusion of reasoning about association topics was developed, and textbook entries were…

Describes the "cloze" procedure for judging the readability of textbook prose and in particular how this procedure may be applied to written mathematical materials. (JP)

Examines how selected U.S. and Asian mathematics curricula are designed to facilitate students' understanding of the arithmetic average. Discusses similarities and differences of learning goals, focuses, and concepts among U.S. commercial, Asian, and U.S. reform curriculum series. (Author/KHR)

This review discusses instructional materials as the physical media through which the intents of the curriculum are experienced. Studies of innovative science curricula are considered, as well as the role of textbooks. (MNS)

The need for developing a geometry curriculum sequence is discussed. Work by a group of about 50 mathematics educators on intuitive aspects of Euclidean classifications and relations is presented. Textbooks were analyzed, a sequence of concept clusters developed, and a scope-and-sequence chart included. (MNS)

The Assessment of Inquiry Potential (AIP) instrument, a tool for classifying scientific materials on the basis of their potential for inquiry learning, is presented and discussed. (MK)
