Levering change is hard, and an incremental process. In the education process it requires an interaction between teachers, resources and learners. Levering change with human resources—teachers themselves, is a long term, time-intensive process requiring investment and commitment. The teacher–resources relationship is complex and not always optimal, particularly in disadvantaged educational environments where resources are constrained, and the education system is centralized and highly regulated. This article posits a mathematics teaching framework developed in a low-income educational context to make more transparent the relationship between teachers and resources to the benefit of learning both of teachers and of learners.

利用变化很难，而且是一个渐进的过程。在教育过程中，它需要教师、资源和学习者之间的互动。利用人力资源（教师本身）的变化是一个长期、耗时的过程，需要投资和承诺。教师与资源的关系是复杂的，并不总是最佳的，特别是在资源受限、教育系统集中且高度监管的不利教育环境中。本文提出了一个在低收入教育背景下开发的数学教学框架，以使教师与资源之间的关系更加透明，从而有利于教师和学习者的学习。
