English language learners

English left Isabella on the outside looking in. FOSS spoke to all her senses, then drew her into reading and writing. FOSS levels the playing field by giving learners multiple ways to engage with the lesson, enticing them in through hands-on exploration rather than text alone.

High-achieving students

Screen-first science bored restless Ethan. FOSS judiciously blends a foundation of active investigations with supplementary online resources and text, to engage students’ hands and active minds.

Struggling students

Lily doubted her ability to learn, until FOSS put control of the lesson in her hands. FOSS active investigation gives even struggling students a chance to relate to the material through their senses, replacing blank stares with the excitement of discovery.
