Study.
Practice.
Teach.
These three things my students get to do in my classes… albeit in micro scale.
You master what you teach… what a great truth this is.
Teach back is one method. In pairs they teach each other one skill/concept/idea that they have just learned. Then share at a larger scale (group of four, then the whole class from a representative from each group of two or four).
Draw: one person draws or pictorially present a short part of what he/she has learned and answers questions about it.
The more you teach, the more you learn, the more you study, the better your practice is, the more valuable you become.
