Many community colleges offer "further education." These are classes offered in addition to a degree program. You can take basket weaving, pottery, etc. You get the idea. That's not what this is about; unless you want to go learn basket weaving...
I am in favor of further (f.a.) education for homeschool moms and dads. One place to obtain f.a. would be an annual conference. Many of them happen during the summer months. Our local one is in June. And THSC has one in August. These are great places to learn about a particular method or how to use a particular curriculum. Some of the speakers are very inspirational.
Another form of further education would be to get acquainted with the education section at your local library. That's the 370's in the Dewey decimal classification system. Some good ones to look at are books on learning styles, tutoring methods, scope and sequences. This is where you will find books on homeschooling.
A sidenote: home education is entirely different from classroom based education. The dynamics are different; less children, your children. I have lots of friends who went to college and earned degrees in education. They will tell you that nothing they learned in college has given them an advantage over the rest of us. In fact, many of them will tell you that they have had to unlearn a few things.
And then, there are your student's materials. I am learning so much reading through my TOG teachers notes. Most homeschool specific curriculum are written by homeschoolers. You get the wealth of their knowledge and experience. Some people will tell you that you can't teach a course by just reading the teacher's manual. I beg to differ. In addition, many homeschool curriculum are written to be read by the student to teach himself.
