Success Case 2 - Before participating in the 3D rocket course, the 9-year-old boy was often impulsive in his actions: he would immediately start working as soon as he got the materials, disliked following instructions, and couldn't persevere with the detailed parts. When doing crafts at home, we often saw him get impatient halfway through and even be unwilling to continue. But under Teacher Yan's guidance, he learned to "slow down" for the first time.
For example, in the lesson on designing the rocket tail fins, he initially rushed to print them, resulting in incorrect dimensions and requiring revisions. The teacher didn't directly solve the problem for him, but instead guided him step by step to observe the problem, adjust the model, and retest. That time, he revised it nine times, finally creating the version he was most satisfied with. For us parents, "this was a BIG DEAL." Because for the first time, he realized that patience, thinking, and trial and error can make the work better and give him a greater sense of accomplishment. Now he is steadier, more composed, and more willing to complete tasks from beginning to end. The Lean Six Sigma methodology brought not only 3D rocket skills but also fundamental changes in the child's habits and personality.
