 The greatest challenge that a teacher faces is marking. Through my social media research, on my travels, visiting schools all across the UK, the greatest burden is marking and assessment. And that's supported by research by the Department for Education. One quick fix is to simply banish the word marking and replace it with feedback. That's a great idea simply because I can give a child feedback in many ways. I can provide verbal feedback, written feedback or even non-verbal feedback. One of the greatest challenges that teachers face, particularly new teachers to the profession, is the burden of lesson planning. With 25 hours of teaching every week, to try and plan to meet the needs of all 30 pupils is a very difficult challenge. If we look at curriculum reform, if you're tweaking the curriculum, coming up with new ideas to better meet the needs of pupils, then experienced teachers also have to revisit all their schemes of work and the resources to then adapt those to meet the needs of their pupils. As we get more immersed with research, with cognitive science, we obviously need to help teachers get better planned in terms of meeting students' needs.
