“如果先不教明概念,便是教得不好的.”夸美纽斯在《大教学论》中的这句话说明了概念教学的重要性.数学概念的产生离不开实践活动和对已知的概念、现象的再认识,数学概念是数学的基础、思维的细胞,在学生思维品质的培养方面有很大的作用,但我们的课堂教学常采用“高起点、大容量、快推进”的做法,忽略了知识的发生、发展的过程,以腾出更多的时间对学生加以反复的训练,无形中增加了学生的负担,泯灭了学生学习的兴趣.我们虽然刻意的去改变教学的方式,但仍有太多旧时的痕迹,若为了新课程而新课程又会使得美景变成了幻景,失去了新课程自然与清纯之味。
“If you do not teach the concept, you can not teach well. ” Comenius in the “theory of teaching” in this sentence illustrates the importance of concept teaching. The concept of mathematics can not be produced without practice Activities and re-understanding of known concepts and phenomena. The concept of mathematics is the basis of mathematics, the cell of thinking, and has a great effect on the cultivation of students’ thinking qualities. However, our classroom teaching often adopts a “high starting point and a large Capacity, fast forward ”, ignoring the occurrence of knowledge, the process of development in order to free up more time for students to be repeated training, virtually increase the burden on students, eliminating the interest of students to learn. Although we Deliberately to change the way of teaching, but there are still too many traces of the old, if the new curriculum for the new curriculum will make beauty into illusion, lost the new course of natural and pure taste.
