PINGO (Peer Instruction for very large Groups) is a web-based Classroom-Response-System designed to facilitate real-time interaction between presenters and large audiences. It is particularly effective in educational and professional training environments to transform passive listening into active participation.

The main features of this service include:

• Live Polling: Presenters can create polls on-the-fly during a session or prepare questions in advance to interact with their audience.

• Frictionless Participation: Audience members can participate using any device with an internet connection. Crucially, participants do not need to sign up or create an account to respond to questions.

• Optimized Results Display: Poll results are designed for high visibility on "big screens" and can be viewed directly in a web browser or integrated into PowerPoint presentations.

• Versatile Applications:

  • Higher Education: Specifically designed to bring "active learning" to large lecture halls with over 500 students.

  • Schools (K-12): Used for checking learning goals, collecting anonymous feedback, and generating tagclouds.

  • Corporate Training: Helps trainers gauge attendee knowledge and gather feedback to improve training effectiveness.

• User-Friendly Design: The tool is described by users as intuitive, reliable, and quick to set up, providing a professional interaction platform "without any folderol".
