                 the construction of simple mathematical proofs. In
                 contrast with traditional linear proofs, this technique
                 helps the student organize the solution process and
                 provides a visual representation of the proof. This
                 approach has been used to introduce proofs in a
                 discrete structure course. The author has observed a
                 statistically significant increase in students'
                 performance when answering related test problems.",
