20世纪70年代,密歇根大学的帕林克萨教授提出了交互式课堂教学理论。该理论认为,教学过程应该以建构学生学习目标为基础,教师在讲授知识的同时,还应意识到学生是主动地进行信息加工的知识创造者,建议着力培养学生的学习能力,这与新课程的理念相吻合。它指导我们教育工作者在讲授知识的过程中,要注重教与学的互动,以达到有效教学的目标。例如,如何在新课程理念下对“握手问题”进行讲授,值得我们每一位教育工作者思考。一、问题的引入1.提出问题美国著名数学科普作家马丁·加德纳提出“握手问题”:几个好朋友见面,2个人互相握手,共握次手;3个人互相握手,共握次手;…,n个人互相握手,共握次手。
In the 1970s, Professor Palinkesa of the University of Michigan proposed an interactive classroom teaching theory. The theory holds that the teaching process should be based on the construction of students ’learning objectives. Teachers, while teaching knowledge, should also recognize that students are the creators of knowledge on the initiative of information processing. It is suggested that students should strive to cultivate students’ learning abilities. This is in line with the new curriculum The concept of match. It guides our educators in the teaching of knowledge in the process, we must pay attention to the interaction between teaching and learning in order to achieve the goal of effective teaching. For example, how to teach “handshake ” under the new curriculum concept is something that every educator should think about. First, the introduction of the problem 1. Asking questions The famous American science writer Martin Gardner proposed “handshake ”: a few good friends to meet, two handshake each other, a total of secondary hands; three handshake each other, hold a total of Second hand; ..., n individuals shake hands with each other, a total of second hand.
