31 top apps for education from FETC 2013 — from The Journal by Stephen Noonoo


Like last year, this year’s popular App Shootout at FETC 2013 tossed around dozens of useful apps for teachers and students. Once again the closeout session was led by ed tech pros Gail Lovely, Hall Davidson, and Jenna Linskens, who each presented apps in three different categories of their choosing, including their favorite “wow” apps. Read on for a selection of the most buzzed about apps for Apple devices. For even more app ideas, visit the shootout’s Web site and complete app list Google Doc.

Per Jim Bradley (Mathematics, Emeritus) at Calvin College:

Francis Su is a Christian teaching at Harvey Mudd, a secular liberal arts college. He was recently selected to receive the Haimo Award*, one of the mathematics community’s highest teaching honors. Receiving the award entails giving an address at the annual math association meeting, going on now in San Diego. In writing his talk, Francis asked himself, “What does the gospel have to say to this large, mostly secular group of mathematicians?” He answered, “Grace.” Here’s a link to a written copy of his talk. I think it’s quite an inspiring and enjoyable set of reflections on teaching by an obviously great teacher. 
(From DSC: Facebook deleted the above original posting by Franic Su — not sure why)

Per Francis’ new blog:
After giving this talk, I had so many requests for the text that I
shared it on Facebook.  But Facebook deleted it.
So I created a blog just for this.  I hope you find it helpful.

It was the hardest thing I ever had to write:
because it is deeply personal, truly me,

and about my biggest life lesson… given at a
conference in front of hundreds of people who,

I’m sure, struggle with the same things that I do.

The Lesson of Grace in Teaching
From weakness to wholeness, the struggle and the hope

Francis Edward Su
MAA Haimo Teaching Award Lecture
Joint Math Meetings, January 11, 2013
An audio file is available:




Knowing my new advisor had grace for me meant that he could give me honest feedback on my dissertation work, even if it was hard to do, without completely destroying my identity.  Because, as I was learning, my worthiness does NOT come from my accomplishments.  I call this

The Lesson of GRACE:

  •      Your accomplishments are NOT what make you a worthy human being.
  •      You learn this lesson when someone shows you GRACE: good things you didn’t earn or deserve, but you’re getting them anyway.

I have to learn this lesson over and over again.
You can have worthiness apart from your performance.
You can have dignity independent of achievements.
Your identity does not have to be rooted in accomplishments.
You can be loved for who you are, not for what you’ve done—somebody just has to show you grace.



From DSC:
Powerful messages…often times, it’s hard for me to get my arms around the lessons/messages that Francis addressed — especially seeing as we live in a world that constantly measures us by our performance, our achievements, and/or our productivity.


* From The Deborah and Franklin Tepper Haimo Award for Distinguished College or University Teaching of Mathematics web page:

In 1991, the Mathematical Association of America instituted Awards for Distinguished College or University Teaching of Mathematics in order to honor college or university teachers who have been widely recognized as extraordinarily successful and whose teaching effectiveness has been shown to have had influence beyond their own institutions. In 1993, the MAA Board of Governors renamed the award to honor Deborah and Franklin Tepper Haimo.

To boldly go where no pupils have gone before — from by James Morgan

Classroom of the future


The researchers behind the design of so-called ‘Star Trek classrooms’ have discovered that multi-touch, multi-user desks can boost pupils’ skills in mathematics. The inter-disciplinary team from Durham University, whose findings have been published in the journal Learning and Instruction, found evidence to suggest that children who used smart desks to complete mathematical exercises benefited more than those who completed their tasks on paper.

During the course of a three-year project known as SynergyNet, the researchers have worked with more than 400 pupils, predominantly aged between eight and 10. The team’s latest results show that collaborative learning, such as that facilitated by touchscreen desks, increases learners’ mathematical fluency and flexibility. Moreover, the researchers are confident that the technology that they have developed could also be used to improve learning across other subject areas.

Comments (emphasis DSC)

  • If you ever wanted to know what four dimensional geometry could be like, install this app. For the low, low price of $2.99, you’ll take an exciting journey into the Fourth Dimension. “Textbook” doesn’t do this app justice, virtually every page is interactive.  — Nicholas Nguyen March 19, 2012
  • “The app is very cool, and it’s unlike pretty much anything we’ve seen in the App Store.” — Sam Byford, The Verge
  • “This is one of my most favorite iOS apps ever.” — George Musser, senior editor at Scientific American and author of The Complete Idiot’s Guide to String Theory
  • “Fantastic! This is what someone really smart, and who really knows how to teach well, can do with a tablet. And the authors are funny, too, which is a neat bonus.” — DNY
  • “Blew my mind. I generally don’t use ‘learning’ apps as they’re mostly gimmicks. This one, though, truly made me think. I hope this developer comes out with more outstanding apps such as this one. Bravo!” — Iceitic
  • “Fantastic app. I work at a leading UK university. If only all our material was this well written and presented. Definitely worth buying and then spending a bit of time with over a day or two to get your head around the fourth dimension. Great app!” — JulesFM

  • ‘The Fourth Dimension’ for iOS: learn to see in 4D (hands-on) — from the by Sam Byford
    It’s priced fairly low ($2.99 for a universal iPhone/iPad app) and uses innovative design to explore a single, focused concept, and while you’ll be done with it after twenty minutes or so that actually adds to the appeal. It’s a bite-sized chunk of brain training that’s a lot of fun to wrap your head around, and it probably couldn’t have been produced any other way. That’s about the most you can ask for in an app these days.

5 ways to identify and support budding mathematicians — from by Katie Haydon, founder of Ignite Creative Learning Studio


Attention kindergarten, first, and second grade teachers: You likely have a budding and brilliant mathematician among your classroom ranks! That child may sit quietly while the other students “catch up” and learn basic math concepts covered by early primary curriculum, or he might refuse to do the work and goof off during math time. This behavior may suggest that this child is behind, but the following points will help determine if this is a valid conclusion.
