实施新课改,为课堂教学注入了新的血液。怎么去把握好课堂,又怎么上好课,是每一个教师都在不断思考的问题。为此,我针对自己的教学实践,谈谈小学数学课堂教学的三点思考。一、算法多样化与优化《义务教育数学课程标准(2011年版)》提倡算法多样化,并非要求学生一定要掌握多种计算方法;也并不是要求学生硬性地去寻找出多种的算法。算法多样化应是学生在探索算法的过程中自然形成的。新课标中所提及的算法多样化与优化,是指集体的多样化,个体的优化。也就是说要求全体学生尽可能地多想出几种不同的算法,而
Implementation of the new curriculum reform for the classroom into a new blood. How to grasp the classroom, how good class, every teacher is constantly thinking about the issue. For this reason, I talk about my own teaching practice and talk about three points of thinking in primary school mathematics teaching. First, the algorithm diversification and optimization “compulsory education mathematics curriculum standards (2011 Edition)” to promote the diversity of algorithms, does not require students to master a variety of computational methods; also does not require students to rigidly find a variety of algorithms. Algorithm diversification should be students in the process of exploring the algorithm naturally formed. The new curriculum standard mentioned in the algorithm diversification and optimization, refers to the collective diversity, individual optimization. This means that all students are required to come up with as many different algorithms as possible
