My approach to topics is to protect and create a situation where my customers become enthusiastic about understanding the subject matter at hand themselves and consequently deeply integrate new content and frames of meaning into their way of thinking. This approach can generally be called customer-centred and problem-based. My best sharing has been due to intrinsic interest, usually oriented to a practical purpose. My customers play a major role in deciding format, content and assessment; This, I know, is the most effective learning experience I can provide.
