These changes to our education system are not going away or slowing down.
I've been following this trend for nearly 15 years (since my ex-wife and I homeschooled our own daughters) and even more closely over the past 5 years as POD publishing technologies have continued to develop and increase in quality and distribution.
One of the BIGGEST driving factors in this massive movement is the desire and need to customize and individualize education. For instance, when my girls were being homeschooled, my daughter, Ashlea, wanted to learn another language but had no desire to learn Spanish, French or the other commonly taught languages. She wanted to learn Cherokee. In public school that would be impossible...and it was a challenge even in homeschooling. Why? Because there wasn't formal curriculum to learn Cherokee! We were ultimately able to get the info she needed to gain credits for Cherokee...and she took it for 4 years! Ashlea ended up graduating a year early with honors.
What we do NOT need are more textbooks, but rather, more focused modules on topics our children want to learn about.
And therein lies the opportunity for you and me!
