Practice is an interactive video and mobile platform that scales the development of skills that require practice to learn and and demonstration to assess. Practice offers a patented, multi-step video learning process that was developed through consecutive National Science Foundation research grants aimed at scaling training and skill development. Created by educators, the key components of the Practice platform mimic the most effective face-to-face instruction: deliberate practice, peer interactivity, self-reflection, and coaching. Practice is used by Fortune 50 companies, leading higher education institutions, and prominent hospitals and healthcare systems to make learning more efficient, effective, and engaging.
