In the Badge interface, found in the Photon EDU app, choosing the blue color will make the robot turn right, while choosing the yellow color – left. To begin, the teacher puts a blue and a yellow band on each of the robot’s antennae. Similarly, students put the bands on their hands – blue on the right, yellow on the left. Students then map the robot’s path from point A to point B, turning along the way to, for example, avoid obstacles.
The colors allow them to tell left from right much more easily while observing the robots’ movements in the real world helps them grasp the concept of directions much more quickly. Moreover, they learn to predict what the robot will do after they choose a particular color assigned to a specific direction, allowing them to program the robot at will. Finally, children simulate the robots’ movements, while the colors help them consolidate their newly acquired knowledge.
