随着新课程改革的不断推进,小学生的计算能力出现了下降的趋势。学校教务处多次调查分析表明:教师,仍然受传统计算教学注重算法和训练的影响。学生,多数是因为算理不清而导致的。那么,如何让学生充分体验由抽象算理到直观算法的过渡和演变过程,从而达到对算理的深层理解促进学生对算法的切实把握呢?在数学特级教师、骨干教师的引领下,我们申报了 With the continuous advancement of the new curriculum reform, the computing power of pupils has shown a downward trend. School Academic Office repeatedly survey and analysis shows that: teachers are still subject to traditional computing teaching algorithm and training. The majority of students are caused by unclear calculations. So, how to enable students to fully experience the transition from the abstract algorithm to the intuitive algorithm and the evolution process, so as to achieve a deep understanding of the algorithm to promote students to grasp the algorithm? Under the guidance of mathematics teachers, key teachers, we declare It’s
