The College Board developed a program in the content areas of English and mathematics designed to prepare students for challenging content as early as grade 6 and extending through high school. Conceived with the goal of creating high-quality professional development activities with associated instructional strategies embedded in instructional materials rich in content and cognitive demand, the resulting Textual Power and Mathematics with Meaning instructional materials and professional development ultimately sought to improve student engagement and achievement in the classroom. The findings associated with the evaluations of Textual Power and Mathematics with Meaning in years 1 and 2 of the pilot informed the development of their current forms in the SpringBoard Program.
