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...

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....

Advice from iPhone owners

Category : General

Hey iPhone owners,

I’m curious about something.

I have an iPod Touch and it is driving me crazy. It may be the reason I do not get an iPhone. Here’s my issue…

How do you keep the darned screen clean?

It’s more than cosmetic, it keeps me from typing. There are times I want to type a letter t and cannot because I have been navigating, playing, or what have you, and there are enough built up fingerprints there that it blocks the letter. I can roll right over it and it never registers. I rub it on my jeans, shirt, hot breath cleaning technique and nothing. I power it down, all the way, and still nothing.

I end up having to use some sort of cleaner (approved for the device, thank you) and let it sit a while.

How in the world do you prevent this from happening? It would be detrimental if I wanted to send an email and could not. It’s kept me from twittering many times, and I’m not sure that’s all bad.

Ok so help me out here, eh?

Thanks…

Chris

My started like that and eventually got to the point where I couldn’t get the screen to respond at all. I’m anxiously awaiting my replacement Touch right now. From what I could find on-line, it is not an uncommon problem. Applecare is a great thing though.

Chris,
I have an iPhone and had the same problems at the beginning. I don’t use make-up and don’t have “greasy” skin either, but the surface felt horrible. I then bought a special screen overlay at the apple store and never had to clean it since then (last April)! That worked for me.

I bought the static cling scrren overlay too – it works great. I was worried that it would slow the touch screen down, but the difference isn’t noticable.
