“There are times when students will fail to learn despite the best efforts of the teacher. Master teachers who differentiate instruction and respond to student needs still encounter students who struggle to learn the content required by the curriculum. As teachers take note of the student who is failing to respond to the teaching methodology, they need to consider how to re-approach the subject and intervene so that students will become successful.”
