Navigating the Challenges of Helping Teachers Use Data to Inform Educational Decisions.

In this paper we present a model of collaborative evaluation that has been used to engage teachers in data-based decision making for improving teaching and learning in mathematics and science. We examine three external challenges that threaten the process of continuous school improvement; namely, making sense of data, policy changes, and curriculum changes. In addition, we describe how the collaborative evaluation model facilitated progress beyond these challenges. Keywords: data-based decision making, evaluation, mathematics education, science education
