Subject: Value of two-column proofs in geometry

Should geometry proofs be de-emphasized to create more time to cover additional material? No. Geometry proofs are just about the only thing to survive from a geometry course which you can put to use in higher math courses: the discipline, the structure, the linking, the logic. True, geometry proofs don't show up on the ubiquitous entrance or exit tests, but they do teach students to think logically.
