MIT App Inventor 2 alpha: A great way to introduce kids to Android

MIT App Inventor 2 alpha: A great way to introduce kids to Android

App Inventor has been around since
2010 — first as a Google maintained project, and then it was handed off to the
Massachusetts Institute of Technology (MIT). Through the years I’ve experimented with App Inventor with varying degrees of success. However, I find the new alpha is easy to get the hang of and is quite stable.

What is App Inventor?

The
idea behind App Inventor is that, by using an entirely visual tool, computer-programming concepts can
be taught in a manner similar to fitting the pieces of a puzzle together. I think the appeal of App Inventor
over similar tools such as Scratch and LEGO MINDSTORMS is that it runs entirely online, and the resulting application can be
transferred painlessly to the user’s phone over Wi-Fi. Everyone right now is in love with apps, and this is doubly
true of children in my experience. Kids light up at the idea of being able to create their own app and run
it immediately on their own (or their parents’) Android device.

App Inventor resources

Besides the official App Inventor website that hosts the
project, there are a couple other of really good App Inventor sites. These contain everything from simple
collections of tutorials to an entire college level computer course curriculum presently taught at University of San Francisco.

Using App Inventor 

I could go on describing App Inventor
and its merits, but the most compelling reason for using this
educational tool lays in its visual aspects, thus three screen shots are
in order.

1. The first thing you do to create an app with App Inventor is layout your screen (Figure A).

2. Select the blocks specific to your component and task (Figure B).

3. Put the blocks into logical order using
the interlocking puzzle pieces as clues (Figure C).

An educational tool for kids

App
Inventor has evolved from its rather clunky beginnings, honed in on its educational roots, and reached a level of polish in the alpha version that makes it a fantastic way to
introduce middle school-aged children to the concepts of computer science.
