Richard Churches has worked very closely with teachers on the Closing the Gap project and knows how to guide them through the research process. The success of the Closing the Gap research rested on us all following good scientific method and being confident in our conclusions. Teacher-Led Research, which offers a clear structure to work through and accessible explanations, will be equally useful to the inexperienced teacher-researcher and the more experienced leader guiding a group. Running a randomised controlled trial in my own classroom led me to realise the value of teaching approaches I had thought were relatively ineffective, so I recommend the process described in this book. I never thought that I would spend my Saturday evening reading about inferential statistics but found the explanations here much more accessible than in standard texts. Even if you think you have a reasonable understanding, there is much to learn from this book. With a bit of experience, you can dip in and out of this book to clarify and develop your thinking. However, I would recommend that, first time through, you follow the guidance to the letter.
