The Twin Triangles
[Ed. Note: The image on the right, "The Learning Pyramid," is NOT based on any verifiable research; perhaps, no research at all (see this and that). This pyramid is widely cited yet it is, as Christopher Harris shared in an email, a hoax. You can learn even more about the origins of the Learning Pyramid hoax here. Nonetheless, I stand by the idea that the marriage of teaching and content creation is a powerful pedagogical practice (see this).]
What I call "The Twin Triangles" provides a paradigm for instructional design that leads to powerful learning on the part of students.
The marriage of the concepts represented in these two triangles leads to students having long lasting (in term of effect) learning experiences. I try to design learning experiences for students where they create content that educates.
