Key visualizations

A rich body of research indicates that authentic interactive visualizations of key concepts can promote engagement by students and lead to greater mastery of them as measured by performance on assessment tasks.

The animations sampled here were developed in collaboration with hundreds of exemplary mathematics educators throughout the country as part of a system of programs intended to enable every student to have the opportunity to succeed in learning challenging mathematics and science concepts, supported by a teacher who has access to the most promising practices in instruction and formative assessment. The comprehensive Biology program, available to schools and districts by subscription, contains more than 200 research-based animations of key concepts.
