实施单元教学面临的一项具体工程,就是如何目标明确地调控单元中的教学内容,勾通整体单元与散篇教材之间的联系,从而构架起多维的立体的全新的单元整体教学实体。集纳,正是实施这一控制的一种有效手段。集纳者,制约调控、删繁就简、去粗取精、求同存异、集纳归纳、重新组合之谓也。单元教学中的集纳是多方面的:有教学目的要求的集纳,有教学重点难点的集纳,更有知识点训 The specific project faced by the implementation of unit teaching is how to explicitly govern the teaching content in the unit, linking the relationship between the whole unit and the scattered teaching materials, thus constructing a multi-dimensional and three-dimensional whole united teaching entity. Concentration is an effective means of implementing this control. The arbitrators, restricting control, reducing cumbersomeness, simplifying, taking rough, seeking common ground, retrieving, reassembling, and reassembling are also known. The unity of unit teaching is multi-faceted: there are intensive teaching requirements, there are intensive teaching and learning difficulties, and more knowledge training.
