Drawing on prior work and a pilot study of DNR based instruction. The PI observed that such instruction has brought about positive change in teachers' knowledge of algebra, in their use of justification and proof, in their understanding of how students learn, and in their practices of teaching mathematics. Consequently, the general goal of this proposed research is will, and if so how will, a DNR-based instruction be effective in developing the knowledge base of algebra teachers, particularly with respect to mathematical, cognitive, and instructional aspects of proof schemes? Teachers will be randomly assigned to treatment and in the last year of the study explicit links to student achievement will be estimated.

利用先前的工作和基于DNR的指导的试点研究。 PI观察到，这种指示在使用理由和证据，了解学生学习方式以及他们的教学数学实践时，对教师对代数的知识进行了积极的变化。 因此，这项拟议的研究的一般目标是意志，如果是这样，基于DNR的教学将如何有效地发展代数教师的知识基础，尤其是在数学，认知和教学方面的证明方案方面？ 将估计教师将随机分配到治疗中，并在研究的最后一年明确链接与学生成就的联系。
