Decades ago, while meandering through a magazine, I stopped at a letter to the editor, entitled something like “Jigsaw Puzzle Education.” The writer was troubled at the state of education, claiming that teachers were not connecting one fact or idea to another. His analogy went something like this: teachers ask students to learn that 2 + 2 = 4, but without any reference to the broader context of life.
He said that this way of teaching is similar to asking students to connect two pieces of a 500-piece jigsaw puzzle without ever seeing the picture on the box. Two facts may connect, but for the students, it has little meaning beyond that. The writer said it would be frustrating for students, seeing no sense in learning the tidbit connection without seeing how it fits in the whole picture.
