There is a vast amount of research on what goes on in schools, but how can school leaders sort credible findings from dubious claims and use these to make informed decisions that benefit their schools? How can abstract ideas from research be translated into dynamic plans for action? This book is a practical guide to evidence-based school leadership demonstrating the benefits that can be gained from engaging with robust educational research and offering clear guidance on applying meaningful lessons to practice. Topics include:  • What is evidence-based school leadership and why does it matter?  • How to collect data from your own school and how to analyse this evidence in order to inform strategic leadership decisions  • Models for implementing school improvement and change  • Leadership skills for fostering a culture of evidence-based practice This is essential reading for senior and middle leaders in educational organisations who aspire to lead effective schools with high levels of staff well-being and enhanced outcomes for the learners they teach.

Aggregating sources of evidence

Aggregating sources of evidence

Chapter outline

This chapter will look at how to go about aggregating different sources of evidence. First, consideration will be given to relatively simple ways of aggregating research evidence through the use of tables. Next, the challenge of how different sources of evidence – be it school data, stakeholders’ views, practitioner expertise and research – can be aggregated will be explored. This will lead on to a discussion of how logic models can help aggregate the available evidence. Finally, the chapter will suggest a number of techniques the evidence-based school leader can use when judging both the quality of the aggregation and synthesis of the evidence.
