计算是小学数学教学的基本内容,在教材中所占比重很大。培养学生计算能力一直是小学数学教学的主要目的之一。《数学课程标准》明确提出:在“数与代数”的教学中,应帮助学生建立数感和符号意识,发展运算能力和推理能力,初步形成模型思想。多媒体凭借其丰富多彩的信息资源、形象直观的交互学习环境,为学生的自主学习、合作探究开辟了广阔的空间,提供了理想的条件。教师以课程标准和教材为基本依据,学生在教师启发指导下,借助多媒体解难释疑,解决实际问题,从而获得知识、技能、情感与态度的多元化发展。因此,如何充分挖掘和发挥多媒体教学的独特优势,提高计算教学的有效性,对提高学生计算能力显得尤为重要和必要。 Calculation is the basic content of primary mathematics teaching, teaching materials in a large proportion. Developing students’ computing abilities has always been one of the main purposes of primary school mathematics teaching. The standard of mathematics curriculum clearly states: In the teaching of “number and algebra”, students should help to establish the sense of number and sign, develop the ability of computing and reasoning, and initially form the model. With its rich and colorful information resources and intuitive image interactive learning environment, multimedia has opened up a vast space for students’ autonomous learning and cooperation exploration and provided ideal conditions. Teachers based on curriculum standards and teaching materials, students under the guidance of the teacher inspired by multimedia solutions to resolve problems and solve practical problems, so as to obtain the diversified development of knowledge, skills, emotions and attitudes. Therefore, how to fully tap and exert the unique advantages of multimedia teaching and improve the effectiveness of computational teaching is particularly important and necessary to improve students’ computing abilities.
