Thanks Ivan, Jose and Bruce for your thought-provoking comments.
As I can see from your comments, it is important to put information into context when presenting to an audience. It is also important not to overwhelm the audience with too much detail.
The reference to cognitive learning theory is interesting Bruce. There could be a cultural element to this also. I have visited Japan lots of times in the past and I have been amazed how information is presented. For example, consider Japanese web design - see https://randomwire.com/why-japanese-web-design-is-so-different/ This cultural factor could be important when we are teaching to a foreign audience.
I have checked out the Prezi web site, eg the "Heimathafen" example at https://prezi.com/explore/staff-picks/ I like the dynamic movement over the "slide terrain" and the "zooming in and out" - a bit like using the "Forecast Funnel" in weather forecasting.
So for the purpose of this email I have come up with a "Focussed Bento Box PowerPoint" presentation option. A sort of "poor man/woman's Prezi option".An example is attached to the post.
Please let me know how you like this option. Also, it would be great to get your feedback about my recorded presentations. What worked well and what could be improved. That would really be valuable to me...
