Overview
Students use the App Lab programming environment for the first time and become acquainted with the turtle. The chief problem is to find the most “efficient” way to draw an image of a 3x3 grid using a limited set of only 4 commands.
Vocab
- Pair Programming - A method of programming in which two programmers write code using a single computer. One programmer in the
"driver" role uses the mouse and keyboard to actually write the code while a second acts as a "navigator", keeping track of the big picture, catching errors, and making suggestions. Programmers switch roles frequently and communicate throughout the process.
- Turtle Programming - a classic method for learning programming with commands to control movement and drawing of an on-screen robot called a "turtle". The turtle hearkens back to early implementations in which children programmed a physical robot whose dome-like shape was reminiscent of a turtle.
