Teacher professional development is usually directed and governed by three agents: politics, pedagogy and innovation. The book begins by considering existing literature and ideas on teacher professional development. Chapter two briefly outlines some of the issues in science education that are of relevance to primary school science while also examining the PIPS model of teacher professional development. Subsequent chapters focus on the methodology employed by the project including details of the evaluation, as the data collected was instrumental in determining influential facets of the project. The following chapters explore the notion of readiness, risk, reflection, recognition, resource and relevance. These were deemed to be key elements that contributed to the success of the project in terms of promoting professional development and in terms of seeing tangible change in classroom practice. There is a short chapter which outlines some of the other project findings and the book concludes with a chapter on the need and challenge for dynamic teacher professional development programmes that work in partnership with teachers rather than deliver things for teachers.
