对小学生数感的培养,简单理解,就是培养学生的数学化,帮助学生学会用量化的眼睛去看待周围的世界,进而将相关问题自然地与数学结合起来进行思考。由于这种感悟具有模糊性、个体性、内隐性等特征,故而在日常小学数学教学过程中,很难将其量化,亦难以使用有效的方法对此进行较为科学的检测。那么,应怎样落实小学生的数感培养并取得一定的实效呢?我以为关键在于帮助学生建立起对数的感知,加深领悟,并借助训练使其效果明确化。
The training of elementary students ’sense of number, simple understanding, is to train students’ mathematics to help students learn to quantify the world to see the world around, and then naturally related problems with mathematics to think together. Because of its ambiguity, individuality, and implicitness, it is difficult to quantify this knowledge in everyday primary school mathematics teaching, and it is hard to use effective methods to conduct a more scientific test. So, how should we implement the primary school students sense of flu training and achieve some results? I think the key is to help students establish a sense of logarithm, deepen understanding, and use training to make its effect clear.
