You can’t force understanding.
The best information in the world is useless unless you can impart it concisely, cleanly, and with understanding. To achieve this you must effectively engage your audience, whether it is a boardroom, a class full of bored students, or a seminar.
Engaged people are Learning.
Understanding what gets an audience interested, understanding context, involved and interacting is key to others deeply and broadly comprehending what you are presenting.
As a Training/Learning mentor I consult on a number of techniques and patterns to help people become more effective and stand out from the crowd across all verticals and industries cross-culturally throughout APAC, the US, and EMEA.
Be effective, and have your audience remember everything. Involve them, and they will understand.
