Rock et al. (2008) suggest the REACH framework for differentiated instruction.
step 1: Assess your practice and identify what areas work well, what areas might need to be adapted or change and what interventions can make these changes happen.
step 2: Evaluate the curriculum and what elements within it will interest students and what they can link to their previous experiences and past instruction. Identify possible areas which can be challenging for some or can provide the basis to stretch others.
step 3: Analyse the learners. Think about their collective and individual weaknesses, strengths and what causes might lead to less or more engagement by some.
step 4: Plan research-based lessons which will enable you to use various strategies to teach the same content to a diverse group of boys.
step 5: Assess the impact of the lessons through formative assessment and reflection on the outcome of instruction goals.
