Narrative:
A commercial student and I had announced downwind for 6R at kenosha airport on 122.7 unicom. Student had just pulled carburetor heat when we noticed an small aircraft B with floats coming right at us at the same altitude and upwind direction. The small aircraft B turned x-wind in front of us (his left, our right) causing us to take violent evasive action. The B continued base and final and landed. I don't think the pilot ever saw us at all. Nonstandard approach to pattern by B caused the near miss situation. No radio communication by B pilot was a contributing factor.
