Add a speed control to Maze app. #127

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
In a large Maze (level 10), we need ability to speed up the walk process. It 
should be a similar thing in "Turtle Graphics" app.

We tried that with a group of students.  Unfortunately not one of them used the 
speed control for its intended purpose.  Its only use was to speed up the maze 
so that all ability to observe the execution was lost, which led to a rapid 
cycle of randomly editing blocks, testing, and more random edits.  The speed 
control turned into a negative feature which prevented learning.

Instead, we are going in the opposite direction.  We will be adding an animated 
icon so that when Pegman looks in a direction (with an if block) then the user 
will see that action.

It's a tough problem.  Non-programmers (our main audience) don't react the way 
we expect.

I would agree with the first poster here, especially level 10. When trying out 
the logic you may need to wait a few minutes before realising that your "code" 
is wrong. Maybe the speed could be adjustable but the maximum speed is not 
quite as fast?
