With regard to the evolution of Marxist theories affecting the relationship between China and Taiwan historically and conceptually, this paper starts with the conceptual framing of the general evolution of Marxist theories--Marxism, neo-Marxist, and post-Marxism. Through dialectical and reconceptualized practice and learning the development of modern Taiwan in the evolutionary modes of Marxist theories, the relationship between China and Taiwan is interpreted as an ambiguous pattern which has evolved from Marxism, neo-Marxism, to post-Marxism. The purpose of this paper is not focused on Marxist theoretical work, but instead, to provide the concentrated themes--the suggestions of creating a dialogic classroom in three curricular methods--currere approach, critical theory, and postmodernism. The paper will conclude that in a debate over China-Taiwan-relationship issues, both sides will imperatively recognize the historical past, focus on the present moment, and have the prospect of a future with mutual benefits.
