Project Lead the Way in Action
In this PLTW module, students work together to build a program using code cards to direct Rosie the Robotic Dog (played by Ms. Calhoun) through a maze ultimately ending at her doghouse. Rosie must jump over mud puddles and collect bones along the way. Students write the program using code cards in order to start Rosie on the Start tile, follow the correct direction of the arrows, make half and quarter circle turns, pick up bones, and jump mud puddles. This task is not as easy as you think. The program for Rosie includes code cards that make her move forward, turn left or right, jump, take a bone, and repeat loop (a sequence of instructions that is repeated a specific number of times). If Rosie steps in a puddle or falls off the path, programmers have a "bug in the program." Program teams then have to fix (debug) the program by rearranging the code cards and trying again. When Rosie makes it to her doghouse with both bones and clean feet, the programmers say, "Program successful!" PLTW modules allow students to engage in challenging activities, projects, and problems that encourage a design-thinking mindset to become creative, collaborative problem solvers ready to take on any challenge.
