“引桥”本意是指从正桥伸向岸边的过渡桥,用来连接正桥和陆地,使桥和岸上的路平稳衔接。在长期的教育教学实践中,笔者发现,孩子的校园生活及学科知识的学习,也都需要这样的引桥。“引桥”课程,就是为了更好地破解学科教学难点,在学习该知识点前进行引桥的搭建,对与之相关的前置知识进行补充或拓展,并进行有的放矢的教学设计,从而让学生顺其自然地接受,起到事半功倍的作用。 “Approach the bridge ” Intended meaning refers to the transition from the bridge to the shore of the bridge, used to connect the main bridge and land, so that the bridge and shore smooth road convergence. In the long-term teaching practice, I found that children’s school life and academic knowledge of learning, but also need such a guide. “Lead the bridge ” course, is to better solve the difficulty of subject teaching, learning lead in the knowledge of the construction of lead bridge, the pre-knowledge associated with the supplement or expansion, and targeted teaching design, so that Students follow their natural way, play a multiplier effect.
