"The Future of Industrial Training: the New Digital Classroom"



About the Webinar:
At TPC Training Systems, we’ve been on the hunt for ways that our industrial skills training solutions can evolve to meet the needs of all of our customers, and we’ve learned some things in the process. In this webinar, we’ll share what we’ve learned and give you a preview of the future of industrial training.

You’ll learn about:
  • The best uses of webcast and simulcast training formats
  • The advantages of blended online and live training
  • Virtual reality (VR) training environments, including an exclusive sneak peek inside a VR simulation
