Twilio for Calculus Class at Ohio State University` The Ohio State University professor, Jim Fowler, recently shared a positive experience with Twilio's service in his calculus class. He used the service to have students report their answers using their cell phones, which allowed them to receive instant feedback and enjoy the process of solving problems without revealing their work to others. The integration was seamless, and as an instructor, Fowler appreciated the benefits it brought to his teaching approach. To support innovative educational apps like Fowler's, Twilio provided him with credits to ensure the app stays up and running until a grant is secured.
