he hedgehog signalling pathway is highly conserved and seen in organisms ranging from Drosophila to humans. This pathway is Tcritical in determining cell fate decisions in a variety of different cell types. There are several vertebrate analogues of the Drosophila hedgehog protein of which the most widely studied is Sonic hedgehog (Shh). Shh signalling classically involves the Gli family of zinc-fmger transcription factors. The Shh signalling pathway is well characterised in the develop ment of a number of vertebrate organ systems. It could indeed be argued that the Shh and Gli signalling may...

This book reports valuable research from across the world that addresses questions on what background and contextual factors are related to achievement in mathematics and sciences. All studies utilized data from the Third International Mathematics and Science Study (TIMSS) conducted under the auspices of the International Association for the Evaluation of Educational Achievement (IEA) in 1995, and repeated in 1998. In many countries researchers have started secondary analysis of the data in search for relationships between contextual factors and achievement. In these...

This book explores an under-researched but vital part of education: the first year at primary/elementary school. The work shows that children’s progress varies enormously from school to school, class to class and child to child. This variation is important because the more progress that children make in that first year of school, the higher their academic attainment at the end of compulsory schooling.The iPIPS (international Performance Indicators in Primary Schools) project, upon which this book is based, has been able to provide deeper insights into some of the key issues within and...
