Learning progressions – descriptions of increasingly sophisticated ways of thinking about or understanding a topic (National Research Council, 2007) – represent a promising framework for developing organized curricula and meaningful assessments in science. In addition, well-grounded learning progressions may allow for coherence between cognitive models of how understanding develops in a given domain, classroom instruction, professional development, and classroom and large-scale assessments. Because of the promise that learning progressions hold for bringing organization and structure to often disconnected views of how to teach and assess science, they are rapidly gaining popularity in the science education community. However, there are signi?cant challenges faced by all engaged in this work. In June 2009, science education researchers and practitioners, as well as scientists, psychometricians, and assessment specialists convened to discuss these challenges as part of the Learning Progressions in Science (LeaPS) conference. The LeaPS conference provided a structured forum for considering design decisions entailed in four aspects of work on learning progressions: de?ning learning progressions; developing assessments to elicit student responses relative to learning progressions; modeling and interpreting student performance with respect to a learning progressions; and using learning progressions to in?uence standards, curricula, and teacher education. This book presents speci?c examples of learning progression work and syntheses of ideas from these examples and discussions at the LeaPS conference.

This volume, developed by the Observatory together with OECD, provides an overall conceptual framework for understanding and applying strategies aimed at improving quality of care. Crucially, it summarizes available evidence on different quality strategies and provides recommendations for their implementation. This book is intended to help policy-makers to understand concepts of quality and to support them to evaluate single strategies and combinations of strategies.

Now in its ninth edition, Phonics Pathways (with help from Dewey the Bookworm™) teaches students of all ages the rudiments of phonics and spelling with an efficient, practical, and foolproof method. Written in an easy-to-use format, Phonics Pathways is organized by sounds and spelling patterns. The patterns are introduced one at a time and slowly built into syllables, words, phrases, and sentences. Printed in a large 8-1/2" x 11" lay-flat format for easy photocopying, Phonics Pathways is filled with illustrative examples, word lists, and practice readings that are 100 percent decodable. While appropriate for K-2 emergent readers, this award-winning book has also been used successfully with adolescent and adult learners, as well as second language learners and students with learning disabilities such as dyslexia.
