在实施新改的过程中,课程标准指出要倡导算法多样化,但是很多教师在实施时在很多环节上走进了误区。误区一:概念误区,与“一题多解”混淆;误区二:算法“多多益善”;误区三:提倡算法多样化,就必须让学生掌握教材中的每一种方法;误区四:不明确算法优化的主体是谁,什么时候优化。教师要注意这些误区,以优化算法。
In the process of implementing the new change, the curriculum standard pointed out that it is necessary to advocate the diversification of algorithms, but many teachers have gone wrong in many aspects during implementation. Misunderstanding one: the concept of misunderstanding, and “a problem more than solution” confusion; Misunderstanding two: algorithm “more and more Yishen ”; Misunderstanding three: to promote the diversity of algorithms, we must allow students to master each of the teaching methods; : It is not clear who the subject of optimization is and when it is optimized. Teachers should pay attention to these errors to optimize the algorithm.
