I think it is helpful to know why we do something – if we are homeschooling our highschool student, a good question to ask would be: What is the purpose of highschool?
No doubt if we started our homeschool journey in primary school we knew that we needed to teach our kids to read, write and do arithmetic! This gave us purpose, gave us direction. We need the same as we head into the highschool years.
I believe most people would say the purpose is to prepare our students for university – or at the least a job. But this is a limited perspective on education and on our life in general. I would rather see our highschool years as the years we fine tune the character and skills for adult life.
