Often students see Algebra as a collection of numbers and symbols to be manipulated, and never see how it is useful. For this reason, I believe that it is important for students to see Algebra as it is applied to Geometry. Many of the problem situations that students encounter will be geometric in nature. Increase Often Geometry courses begin the year with abstract two column proofs of geometric theorems. Although I feel it is important that student learn to use the deductive reasoning involved in two column proofs, I believe that they are not prepared for it at the beginning of a Geometry course.
Technology is a wonderful tool for geometric exploration.
Proof should come from these explorations. They should discuss their intuitive reasons for why things are true. This should naturally develop into more structured paragraph style proofs as students become more adept at expressing their ideas. Finally students could be exposed to the formality of a two column proof. However, I think that student should always be encouraged to express proofs in their own words and style.
