If you have a child that is a student at pretty much any level, then you need to check out Khan Academy. Even parents can learn a lot from this site, from basic math to trading stocks – there are over 3000 videos and tutorials to learn from.
I started a couple of weeks ago having my youngest son use Khan Academy to learn and review school subjects and even simply watch things on the site that interest him. I am sure teachers will have a different opinion about the site but I promise, this site only supplements what our teachers do, and in fact I think the content of the site should be part of the in-school curriculum or at least as assignments.
I have been watching my sons progress on the site and had an interesting observation when looking at one of the areas he studied on the site. The topic was number lines. You know, those lines that go from -10 to 0 then to +10:
Khan allows for “teachers” to track the progress of a student, look at their daily activity, and even guide them in their learning adventure. After my son did the section on “Number Line 3″ I saw this interesting switch in his proficiency.
This graph shows each question in the evaluation, the score, and the time it took the student to answer the question. A couple of things, it looks like he got almost half of the questions wrong in the beginning. Then, there was a question that took a very long time to answer. What happened was he watched the training video on number lines right on the site (which there is a link to the video during the test to the right, see screen shot below). Once he understood numbers decrease to the left and increase to the right he aced the rest of the questions. The site even offers “hints” for each question. What I really liked about the questions were you had to read them carefully. Here is an example of one of the questions:
I am excited and look forward to watching my sons progress through the content of this site!
Subscriptions now enabled!
Mon, May 20th 2013 9:00p Bob Balfe So I had the pleasure of sitting next to and meeting Drew Neisser (@DrewNeisser), CEO of Renegade LLC on the plane to the IBM Smarter Commerce Global Summit today. We had a lot of great exchanges and he gave me a tip I should I have known already and that was having an email subscription form on my blog. I guess I thought that was “the old” way but Drew convinced me many people use his so I figured I would give it a try.
So in conference fashion you should see some pictures and p [read] Keywords: ibm
The insanity of the Marketing Technology landscape!
Tue, May 14th 2013 7:20a Bob Balfe A very interesting graphic from LUMA Partners (LUMAscape) was recently published. You will notice pretty much all of IBM’s recent acquisitions (in the last 3 or so years) are on this graphic. This is in my opinion a validation of the IBM’s Smarter Commerce strategy as their products become more and more integrated. Having a single company with best of breed technologies integrated and supported by one company makes this landscape a bit more consumable and less daunting.

Creating a custom build with Dojo Toolkit Web Builder
Fri, May 3rd 2013 7:20a Bob Balfe Do you want to use only a small piece of Dojo? Does Dojo have a really cool feature you want but you don’t want to take the entire library?
Then the Dojo Toolkit Web Builder is for you. I recently created a desktop web application where I wanted to use the Swipe function in the Gesture package of Dojo. I am not using a lot of Dojo at all in this application so I really only wanted the dojox.gesture.swipe package. The web builder allows you to select the packages you want and it builds a s [read] Keywords: ibm
My first day with the Microsoft Surface – this is no tablet
Thu, May 2nd 2013 7:00a Bob Balfe I now see the attraction of the Microsoft Surface. While it has been documented, written about, reviewed, etc by many and in a sense does not get the recognition some of the other tablets get I think it is clearly getting short changed. And the reason is…
This is not a tablet, its a PC. It does pretty much everything my laptop and desktop can do and a whole lot more. The “tablet” is very thin and compares nicely against the other tablets on the market. I have the 128GB model an [read] Keywords: desktop
How to add swipe support to your web application

Here are a few good reasons from the documentation:
