I have been following the discussion from afar and plan to remain afar, but one thing vacations do is to open up some reading time. Quite apart from the various disagreements that have surfaced from Peter's initial comments (thanks Peter for getting the conversation started), and speaking for myself, I found the article for discussion difficult to follow. Having people with experience in teacher education programs with on-the-ground experience helping us understand the issues involved (and having time to read the messages!) has been helpful. A lot of people voted to discuss this article, presumably because of an interest in ideas of boundaries and teacher ed and it would be helpful to hear from more of them to understand the full range of issues involved. Meantime, I can offer two bits of accessible information. The first is a copy of the Engestrom and Sannino article which has been published and was forward to me by a grad student as part of his own attempts to understand Yrjo's ideas and the other the fact that "Learning by Expanding", Yrjo's doktorat, is available at lchc. I attach the article for those interested. They expand on what Peter wrote as a summary.
