THE DEMONSTRATION CORNER ARCHIVES

We are in the process of building this. Please see our existing resources at our former website.

Since its early years, The Demonstration Corner has been a favourite feature of the OAPT Newsletter. As you browse this legacy, consider sharing your own demonstrations by writing a short article for the newsletter.

This section of the OAPT web site contains The Demonstration Corner articles sorted by topic. Articles are scanned from print versions of the OAPT Newsletter up to about 2003. Otherwise, they are available as editable PDF files.

The OAPT presented a special award to Ernie McFarland at the 2012 Conference in recognition of 25 years of The Demonstration Corner.
