Went for a course, was shown a learning triangle which show the average student's retention rate. Before we were shown the pyramid, we were asked to guess the order by sequencing the different learning methods ourselves. I got the first and last correct. Least effective in terms of retention rate is Lecture and most effective is teaching others. I thought Reading should do better. I know I learn about investment theories through reading, When I think about my learning of investment, a lot of it doesn't make sense until I think further. Read the questions first, and see if you have the same conclusion as me. 1) If Lecture is least effective, when are people paying good money to go for them? 2) What is the easiest way to apply "Teach Others" without flouting the law and break relationships when what you teach turn out wrong or they applied it ......
