What constitutes good differentiation?
Differentiation works best when teachers know their students and their learning needs so that they can anticipate students' responses and work, to adapt their lesson plans accordingly. As Jayne Bartlett suggests, we need to have a 'strong awareness of an individual pupil's learning context…' taking into account 'how we design the lesson, the resources we use, how we group pupils…'. There is work to be done before the lesson starts to ensure that students' needs are taken into account in the lesson plan.
But differentiation is also responsive; after all, students often surprise us. You might have prepared a lesson, differentiating activities based on what you know about your students. But when that lesson comes around, you'll discover that the student you thought would struggle the most is completing every activity with ease, while the student who you've set the most challenging work for is struggling. That's why differentiation has to be supported by assessment for learning opportunities. As
Ross McGill suggests, embedding multiple opportunities for AfL 'allows the teacher to design and adapt lessons that make the most of every student's potential and attend to weaknesses as they arise.'
Ultimately, differentiation is an important factor for all students in your class. Differentiation is a term we usually associate most with ensuring students with additional educational needs access learning.
