The document discusses the advantages of providing feedback from both a classroom teacher and curriculum team leader's perspective. For teachers, using criteria or stickers to provide feedback can take as little as 15 minutes to mark a set of books while still identifying misconceptions and gaps. This improves both the quality and quantity of student work over time. For curriculum team leaders, feedback allows for more accurate lesson planning based on student understanding, higher expectations for students, and reduced workload for teachers through efficient marking. This leads to improved teaching, student outcomes like exam scores, and greater teacher wellbeing through less time spent marking.
