Sorry, but Dr. Wayne Carley, the publisher of American Biology Teacher, has demanded that I remove the PDF files of my American Biology Teacher articles from the internet or be subject to "legal sanctions."

I have asked Dr. Carley for a clarification because I think his demand has no basis. In each issue of the American Biology Teacher, it clearly states "Authors are granted unlimited noncommercial use."

Email me at if you want a copy of one of my American Biology Teacher articles as allowed under the Fair Use provisions of the U.S. Copyright Code. Please specify which article(s) you desire.
