CarNSteer - Sarah's first Squeak demo

Initial Thoughts of App Inventor

Recently, I was voluntold for a teaching adventure for a local high school.  We were going to meet with high school students for a career day and show off App Inventor 2, having them go through the Magic 8 Ball tutorial.  The night before the presentation, I ran through the tutorial and ended up with this:

Initial Thoughts – Complicated Yet Simple

When I first learned programming, I had it easy – one screen, no drag-n-drop UI, no properties.  For a starting tool, the App Inventor landscape is feature rich, which can be intimidating for someone just starting out.  Designer vs Blocks… the various groupings on each of those screens… if I wasn’t familiar with IDEs in general, I may find this to be a complicated setup.

However, at the same time, drag-n-drop development is a bit simplistic.  No need to remember when to use curly braces or square brackets.  Code blocks are different.  And what’s even nicer with App Inventor is that you can create an app that responds to an accelerometer shake with a few drags of code.

Something else that’s nice is that the App Inventor tutorials are well laid out, making it easy to understand what’s going on.

Puzzle Pieces as Building Blocks

When I first saw the Blocks interface with the puzzle pieces layout, I liked that I could talk to them as pieces of a puzzle.  This also reminded me of Scratch, as I am aware of Scratch and how it is used to get kids into programming.  And deep down, it reminded me of the topic of my first solo speaking engagement – Squeak!

Now What?

Now that the high school engagement is over, I want to play more with App Inventor.  Why?  Because I’d love to expose more people to coding and want to know more about this tool and use it when appropriate.  Will I recreate the Car N Steer demo that I presented in 1999 when I talked about Squeak at the Toledo Area Linux Users Group?  Will I write more apps that work with various sensors in my Android phone?  What will I create next?  Stay tuned, as I suspect another app will happen soon enough.
