Like other countries, Israel had its share of projects that see the implementation of inquiry and higher order thinking in schools as their main goal. However, although many of these projects were quite successful, they did not succeed in changing the bulk of teaching and learning in Israeli schools. This article describes a new national educational policy called "Pedagogical Horizons for Learning". The goal of this policy is to move the whole educational system towards a focus on higher order thinking and deep understanding. Such a move must consider the knowledge gained from previous projects but it must also lean on strategies for implementing systemic educational change. Implementing the goals of the "Pedagogical Horizons for Learning" on a national scale requires simultaneous work on three-dimensions: (a) curriculum, learning materials and standards; (b) professional development; and (c) assessment. The article outlines the plan for each of these three-dimensions and provides some accounts of the first stages of the implementation process.
