成功案例2 -  这位9岁的儿子在参加 3D 火箭课程之前，他做事常常比较冲动：拿到材料就立刻动手，不喜欢看步骤，也不太能坚持细致的部分。家里做手工时，我们经常看到他做到一半就急躁，甚至不愿意继续。但在严老师的带领下，他第一次学会了“慢下来”。
比如在设计火箭尾翼的那一节课， 一开始还是习惯性地急着打印，结果尺寸不对，需要重新修改。老师并没有直接替他解决，而是一步步引导他观察问题、调整模型、重新测试。那一次，他 反复修改了9次，最后做出了他自己最满意的版本。对我们家长来说，"这是一件大事". 因为他第一次体会到：原来耐心、思考、试错，能让作品变得更好，也能让自己更有成就感。现在的他做事更稳、更能沉住气，也更愿意把事情从头做到尾。精益六西格玛方法论带来的不仅是 3D 火箭的技能，更是孩子在习惯和性格上的真实改变。

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.
