Playing with the #SketchpadExplorer app. Download it for free until 11/1/11 via @keypress

Daniel Scher is a principal investigator for The Dynamic Number Project. He works to create the iPad-compatible constructions for the Sketchpad Explorer app. Sketchpad Explorer is the iPad companion to Geometer’s Sketchpad software program – both are published by Key Curriculum Press (@keypress on Twitter).

Daniel will be coming to The School at Columbia University to help me help the 5th grade teachers integrate Sketchpad Explorer into their math curriculum. He’s psyched to watch/evalutate how kids learn with the app versus the software versus without either, and I’m excited to get a full grade of teachers to use a tool that I consider to be an industry standard for math educators. I love Geometer’s Sketchpad, and I recently gushed about Sketchpad Explorer on Scholastic’s Best in Tech Today.

Upon opening the Sketchpad Explorer app, there is an animated proof of the Pythagorian Theorem.

On the bottom right corner is a book icon. This takes you to many options, one of which is to visit the Sketch Exchange community site. From here, you can click Sketch Exchange sketches tagged with ipad, and then you can choose dynamic numberin the tag cloud. These sketches open up with the full Geometer’s Sketchpad software program as well.

There are four pages of sketches to choose from. I initially chose Balance Scale: Solving for Unknowns Part 1. When you choose a sketch, further down the page you’ll find links to download activity notes, worksheets, and the actual sketch with the .gsp suffix. I was super excited to note the CreativeCommons license (!) of Attribution Non-Commercial No Derivativeswhich translates to: Give me credit, don’t make money off it, and don’t alter it. I love Creative Commons almost as much as Geometer’s Sketchpad. 🙂

I had a bit of fun playing with this screen trying to figure out the value of the star and other shapes using the fulcrum, and yes, I think I’m smarter than a 5th grader.

My takeaways from the #ISTE11 exhibit hall

Saying there’s a lot going on in the Exhibit Hall of ISTE11 is gross understatement. Unlike my Aunt Debbie, I made it out of there without four tote bags overflowing with schwag. For me, the Exhibit Hall is about saying “Hi” to vendors I know and trust, avoiding the awkward hard sell, being wow’d by the next “must have” integrative technology, and summoning the joy of trick-or-treating with all the free candy offered on every table.

Below is an incomplete list of booths and presenters (whether old or new to me) I found compelling enough to write down in order to share with my faculty:

Pixologic

Besides the Echo Smartpen, I was psyched to learn about Sound Stickers and Sticky Notes.
Sound stickers – circles you can program with specific audio! Put them on pages of books and kids can tap it with pen to make audio play
Sticky notes – sticky notes with dot patterns just like the notebooks
They are partnering with http://Harvardsquareacademy.org – not public yet – and getting a community of minds from Harvard and MIT sharing content and lessons to give expertise to students in the classroom

Daniel Scher of @keypress is helping us integrate GSP and The Dynamic Number Project

I’ve been a fan of Geometer’s Sketchpad (GSP) since 1994 when I first learned about it as a Senior at Bryn Mawr College. It is among the best examples of educational software out there, as you actually learn the math by using the tool. I wrote a post in January about using GSP to do tessellations in 6th grade math, and Daniel Scher* contacted me about maybe collaborating to integrate The Dynamic Number Project and other great resources.

Last week, Daniel came to The School at Columbia University to meet a select group of teachers, technologists, and math liaisons. He’ll be showing them how to integrate The Dynamic Number Project and GSP into their curriculum, make constructions with GSP, and use the soon-to-be-launched iPad app of GSP! While the initial GSP app will only run interactive scripts, the next iteration will allow the user to make constructions. By getting the teachers’ hands on an iPad2 installed with the GSP app in June, we’re hoping to hit the ground running in September.

* Daniel Scher is a Senior Scientest at KCP Technologies. As per their website, KCP Technologies is the software research and development affiliate of Key Curriculum Press. KCP Technologies developed The Geometer’s Sketchpad®and Fathom Dynamic Data™ SoftwareI’ve used both, and they are both awesome. More information about Daniel is pasted from his professional vitae below:

Daniel is a principal investigator for the NSF-funded project Introducing Dynamic Number as a Transformative Technology for Number and Early Algebra. Previously, Daniel was a program director at Best Practices in Education, where he specialized in educational technology applications and the adaptation of the Elkonin-Davydov mathematics curriculum for first and second graders. He investigated the epistemology and mathematics of Dynamic Geometry® while a researcher at Education Development Center. He is the author of Exploring Conic Sections with The Geometer’s Sketchpad and is the co-author of a geometry textbook and a precalculus Sketchpad module. Daniel received a BA in Mathematics from the University of Pennsylvania in 1989, an MS in Mathematics Education from Cornell University in 1993, and a PhD in Mathematics Education from New York University in 2002.
