This study examines the beliefs of K-8 preservice teachers during a content methods course. The goals of this course included exposing the preservice teachers to student-centered instructional methods for math and science and encouraging the development of lessons that would integrate mathematics and science. Prior research suggested that one must consider preservice teachers 'epistemic beliefs (Cady, Meier; & Lubinski, 2006a) as it influences their interpretation of the teacher education program . In this stua'y, preservice teachers' epistemic beliefs were identijied, their beliefs about mathematics and science teaching and learning were identified and compared, and their descriptions of lessons that integrated mathematics and science were assessed. Findings suggest that preservice teachers made decisions based on an external locus of control and harbored greater anxiety about teaching math as compared to teaching science. They also indicate that the integration of mathematics and science in lesson plans was contrived.

In the United States, fractions are an important part of the middle school curriculum, yet many middle school students struggle with fraction concepts. Teachers also have difficulty with the conceptual understanding needed to teach fractions and rely on textbooks when making instructional decisions. This reliance on textbooks, the idea that teaching and learning of fractions is a complex process, and that fraction understanding is the foundation for later topics such as proportionality, algebra, and probability, makes it important to examine the variation in presentation of fraction concepts in U.S. textbooks, especially the difference between traditional and standards‐based curricula. The purpose of this study is to determine if differences exist in the presentation of fractions in conventional and standards‐based textbooks and how these differences align with the recommendations of National Council of Teachers of Mathematics, Common Core State Standards, and the research on the teaching and learning of fractions.
