The purpose of this study is to design and develop a digital game-based courseware on cubic net called Happy Cuber, and to explore the learning effect by using it on the spatial recognition abilities of fifth graders.

本研究的目的就是设计与发展正方体展开图的数位教材(取名为Happy Cuber)，并且透过本教材来探讨国小五年级学童使用教材后的学习成效。

The experimental group of this study is with seventy-six 5th grade students from three classes using Happy Cuber, and the controlled one is with eighteen 5th grade students from one class using cubic net learning sheets.

实验组进行为期三周每周两次的Happy Cuber实验教学，对照组则在实验期间实施展开图学习单填写的学习。

Besides, the experimental group also shows a significant improvement in the spatial perception, spatial orientation, spatial relation and spatial reasoning. According to the logs recorded by Happy Cuber within the three weeks learning, the progress of the students in accuracy and problem solving time is obvious. The stage of Happy Cuber in developing part is harder than the folding part for students, whether in folding or developing part, the cross-shaped net is the highest accuracy and shortest response in all cubic nets.

从教材操作纪录内容的变化来看，学生在游戏中的答题正确度与解题时间随著教材使用次数渐次提升，统计分析后发现，立方体拆解题型难度要比展开图摺合题型高，十字型展开图不论是摺合或拆解上，在正方体11个展开图中都是费时最短且正确率最高的类型。
