<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">I am interested in math curriculum for the XO. I asked a year or so ago, and got no response, but it seems that things are picking up.<div><br class="webkit-block-placeholder"></div><div>I'm writing a textbook for elementary _teachers_ (hoping to publish this commercially). Along the way, I learned a lot about cognition and curriculum for children.</div><div><br class="webkit-block-placeholder"></div><div>So far the math tools and lessons for the XO seem to be some isolated cool activities. I'm not entirely surprised that education ministers in the targeted countries were hesitant to join the project---there is no curriculum that can be handed to teachers and students. I learned from my experience writing isolated fun lessons in the 1990s that most teachers need training and structure to learn something as new as teaching with technology.</div><div><br class="webkit-block-placeholder"></div><div>Someone asked about MATLAB for the XO. This seems to be way too advanced. The XO needs a better calculator, a spreadsheet program (apparently one is in the works), maybe a baby computer algebra system with a very friendly front end. There is some older, but very well thought-out, software called Function Probe designed by the math education researcher in the 1990s. It does algebra, tables, and graphs in a unified way. She told me that she was going to put it out free, in java. Maybe someone could do an XO version.</div><div><br class="webkit-block-placeholder"></div><div>Please feel free to contact me publicly or privately if you're interested in developing some math curriculum.</div><div><br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="3" style="font: 12.0px Helvetica">Susan Addington</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><a href="mailto:saddingt@csusb.edu">saddingt@csusb.edu</a></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="3" style="font: 12.0px Helvetica">Math Department, California State University, San Bernardino</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><br></p><br class="Apple-interchange-newline"></span></div></span> </div><br></div></body></html>
