Tom: the 2nd question first. In our district we offer 8th grade Algebra I
and 9th grade geometry. I once taught, in another district, a successful
7th grade Algebra I course. It was suceessful only because I had a group
of very highly motivated students. Most of them gave up thier lunch
period to come to a help session I ran on a regular basis. The Math
Coordinator tried to expand the course to 5 sections the next year. It
was a disaster.

As to the first question, most of our department uses a tradional trext
book with a strong emphasis on proofs. I am using Serra's Discovering
Geometry which starts students off by writing paragraph proofs then leads
into flowchart proofs, my favorite. Students are introduced to formal
deductive reasoning at the end of the book and finish off with a rogorous
look at formal proofs. I believe it is the superior approach. Students
still do proofs, but after their are ready. When I was in high school,
too long ago, we had a similar curriculum as you described. We also had a
lot fewer students in our school that followed a Alg I-Geometry_AlgII
sequence. I do not feel that many of today's students are ready for
formal proofs by the 2nd chapter of their geometry book. I am a strong
believer in the use of proofs but I feel students need to be better
prepared first. There is a good article in the Jan 95 issue of the
"Geometry and Proof" by Micahel Battista and Douglas Clemments
