Promethean, a developer of interactive classroom technologies, has created a new personalized learning system called RTPI that sends individualized questions to students' devices and allows them to progress at their own pace. The system provides real-time feedback and adaptive learning. Earlier this year, Promethean partnered with CTB-McGraw Hill to link their student response systems. While the personalized approach is not new, using technology in this way can motivate students by giving immediate feedback and allowing quick progression, though some educators remain skeptical of digital solutions in the classroom.
