I found a 1998 article that wasn't published. It has some bits I can use for Just Add Light.
I have a regular column in The Homeschooler magazine, which is now available for subscription within the U.S. For many years it was The California Homeschooler, and was published for members of the HomeSchool Association of California. The magazine is in transition to a slightly larger issue. The next issue will have my interview with Schuyler Waynforth, and you can get to more information and subscription information here:
I'm named in two articles in the current online issue of The Journal of Unschooling and Alternative Learning.
In "The Challenges and Benefits of Unschooling, According to 232 Families Who Have Chosen that Route", I'm cited as the third most named influence on people's choice to unschool (after Holt and Gatto).
I'm cited in "Unschooling, Then and Now," by Kellie Rolstad and Kathleen Kesson, professors of education whose children were/are unschooled.
