I would not be the teacher I am today, without having had to evolve my own practice over the past 20 years to meet the needs of my students. This has meant that I have had to reciprocate best practice from within my own classroom, to those outside it, as well as be receptive to ideas from outside.The advice I share below is extracted for a chapter submission I wrote for ‘Don’t Change The Light Bulbs: A Compendium of Expertise from the UK’s Most Switched-On Educators.‘ This book offers tips and hints on how to be the best teacher you can be, and is written by some of the most respected leaders in education today. Below I offer a short summary on what my chapter contains (pages 17-19); including a follow-up inclusion the 10 suggestions I originally submitted.In the book, without going into the full detail of what is written, I express the ten following ideas for sharing best practice. 1. Observe colleagues.2. Get on Twitter!3. Attend TeachMeets.4. Teach your students to become smarter assessors (#SmartAss).5. Stickability and lesson planning.6. Use Google documents and Google classroom to collaborate.7. Be open and reflective.8. Speak in front of your peers; develop your own public speaking skills.9. Lazy Teaching by Jim Smith: “you teach less and your students learn more.” How? Well, read this book for full details.10. Finally, start your own professional blog for reflection, feedback and sharing content. It has transformed my practice as a classroom teacher and school leader.My advice in full is written and published in Don’t change the light bulbs: A compendium of expertise from the UK s most switched-on educators. Written by Rachel Jones.26 Ideas for Sharing Best Practice:After a conversation with Rachel Jones about her book and this blog, Jones challenged me [as a follow-up] to write a ‘Teacher ABC: One key thing teacher should know, starting with each letter of the alphabet.’ These ideas serve to remind and provoke thought for sharing and receiving best practice. my 26 suggestions are for personal reflection for yourself or when working with colleagues.A = Answer emails from colleagues in other schools; online and elsewhere.
