无启发作用的

Play is the way to enforce motivation、transform emotion and promote creativity. Since play is a dynamic active and constructive behavior and a pleasurable activity that is engaged in for its own sake. It becomes an important metaphor and means of Derrida's deconstruction. For pedagogy, deconstructive play is ludic、funny and awe-some. It plays in the forms of opening reading、creative dialogue and equal status. Such ludic pedagogy takes profound insights on traditional doctrine.

游戏是引发动机、调节情感、促进认知及提升创造力的一种自由运作方式与态度，由於游戏代表的是动态、主动和建构经验的行为，也是自行参与的愉快活动，在Derrida 解构思想当中乃作为一种去中心化的譬喻与手段，藉以松动僵化的系统结构，对教学而言，这种解构的游戏是嬉戏、有趣且惊奇的，其方式表现在开放的阅读、创造性的对话，平等而无对立的师生关系上，对於传统以来重视规训的教学模式深具反省与启发的作用。
