Knewton’s adaptive learning technology assesses what each student knows and how he or she learns best — then pinpoints how much and what type of content, at what level of difficulty, and in what media format, each student needs to achieve specific learning goals. “Think of it as a friendly robot-tutor in the sky,” says Jose Ferreira, Knewton founder and CEO. “Knewton plucks the perfect bits of content for you from the cloud and assembles them according to the ideal learning strategy for you, as determined by the combined data-power of millions of other students,” he says. Knewton.com just launched — pre-loaded with free content in K-12 math, science, history, and English. It includes a variety of pedagogical approaches to meet varying student needs, including videos made by teachers, courses created by universities, and study guides created by the government for statewide testing.
