On the other hand, Dr. Greg Bahnsen wasn’t involved too much in the Home School Movement, rather, his expertise and influence was in the area of Logic, Philosophy, and Pre-Suppositional Apologetics.

I guess I was just thinking of his writing for the Chalcedon Foundation. I haven't read that much of Bahnsen's work, so I suppose I'd just say that Bahnsen contributed in the sense of helping to foster and defend a homeschooling-friendly worldview.

Yes; Bahnsen wrote some things that were helpful to the Home School Movement, I would agree with you. Most of his work can be found at the Covenant Media Foundation.
