First is an article talking about the practical implications of CLT on the design of learning. The second are some "recent" (as of 2003) developments regarding CLT. Happy reading! Update: I clarified the second...

Practical advice on kids and Android app development After hearing about my students' success developing an Android app, I've gotten several emails asking for more details as to how I practically worked with my kids.

Publishing an App Inventor app to the Android Market As I mentioned earlier, my students and I published an Android app to the Android Market. See those links for more information on the background. This post is decidedly technical. First, once we finished the coding process, we packaged the app for to download to the computer. This is an option in App Inventor. This downloaded an .apk file....

Android App Inventor Issue

Category : Featured, General

I have been encountering a particular issue using Android App Inventor recently. The error message says:

error your build failed due to a server error in the AAPT stage

It turns out this was caused by having too many extra images. Once we removed the additional unused images the problem went away.

Perhaps this will help someone.

Twitter poll: Students that want to create video games

Category : Featured, General

I am working with a brand new class called Media Tech. Kids have naturally divided into groups based on interest, and for most all of their interests I had tools available that they could work with. For example, one group wanted to make videos, and I handed them cameras and a laptop and sent them to find a place to work. One group, however, wanted to make their own video games. I didn’t have an easy answer for them, so I asked my colleagues through Twitter.

Here are the responses, perhaps the resources will be useful for someone else wanting to help kids build video games.

Twitter poll: Do you inspect your new followers?

Category : General

I’ve noticed lately that some of my colleagues online have a very large number of followers. Not to assign them a nefarious motive, but I wondered if folks really check out followers to determine whether they’re real people or spammers. It’s a question that interested me, and just for kicks I sent it out to Twitter. Here are the 15 or so responses that came in within an hour. Looks like most folks do check it out.

  • AX allows you to alter any character's accent always using the same key. This applies to symbols as well. For example 2 then F8 gives ², e then F8 gives é, pressing F8 again gives ê and again gives è and so on. There is no need to remember any key combinations or use different keys for doing what is basically the same thing for example à, È « and ì are all created by typing the base character then F8 as required

  • This project started for two main reasons… 1) I am a feed junkie and having reader w/in Gmail feeds that addiction. 2) I was wanted to see and add things to the full calendar based on the email I was reading at the time. What started as two userscripts has evolved into Integrated Gmail. Thanks to everyone who has provided feedback, beta tested, etc.
