Quizziz is one of those K-12 tools that translates well into corporate training. It adds gamification to training. Each person answers the questions at their own pace. Reinforcement on correct answers is given after each person completes a question. Facilitators can see performance both individually and as a group. Debriefing can be focused on the most confusing points.
This tool also translates well into Virtual Instructor Led Training (VILT).
