Book excerpt: 'A must-read for school leaders and teacher trainers ... I wish every school leader would read this book' Dr Min Du, Teacher, researcher and international education consultant The new, fully updated edition of Ross Morrison McGill's bestselling Mark. Plan. Teach., now complete with a visual guide to the key ideas, illustrated by Oliver Caviglioli. Mark. Plan. Teach. 2.0 includes an illustrated visual booklet, a foreword by Professor Andy Hargreaves and exciting new ideas in line with current best practice, recent thinking and developments around marking and feedback. There are three things that every teacher must do: mark work, plan lessons and teach students well. This refreshed guide from Ross, bestselling author of 100 Ideas for Secondary Teachers: Outstanding Lessons, Teacher Toolkit and Just Great Teaching, is packed full of practical ideas that will help teachers refine the key elements of their profession. Mark. Plan. Teach. 2.0 shows how each stage of the teaching process informs the next, building a cyclical framework that underpins everything that teachers do. With teachers' workload still at record levels and teacher recruitment and retention the number one issue in education, ideas that really work and will help teachers not only survive but thrive in the classroom are in demand. Every idea in Mark. Plan. Teach. 2.0 can be implemented by all primary and secondary teachers at any stage of their career and will genuinely improve practice. The ideas have been tried and tested and are supported by evidence that explains why they work, including current educational research and psychological insights from Professor Tim O'Brien, leading psychologist and Honorary Professor at UCL Institute of Education.
