小学数学新课程标准中增加的教学理念就是运算能力,把培养运算能力作为学生数学学习的核心素养。教学中,应突出计算基本技能训练,加强口算和估算训练,重视口算训练,打牢计算基础,加强估算训练,开拓学生思维;加强对比训练,形成基本算法,注意训练学生看、想、写、算、检等技能的协调性;加强学生对算理算法的理解,在操作活动中探究算理算法;借助直观教学手段,加强教具演示和学生的直观动手操作,把抽象的算理具体化;在讨论交流中内化算理算法,在实践练习中巩固算理算法;提倡算法的多样化与优化,引导学生进行深层次思考,为学生提供交流的机会,算法多样化,多中求简,择优而用。
The teaching philosophy added in the new curriculum standard of elementary mathematics is the computing ability, which regards the training of arithmetic ability as the core literacy of students’ mathematics learning. Teaching, should emphasize the calculation of basic skills training, strengthen the calculation and estimation training, emphasis on port arithmetic training, lay a solid foundation for calculation, strengthen estimation training, develop students thinking; strengthen contrast training, the formation of basic algorithms, pay attention to training students to see, think, write, Calculation and inspection skills; strengthening students ’understanding of arithmetic algorithms and exploring arithmetic algorithms in operational activities; using intuitive teaching methods to enhance the demonstration of teaching aids and students’ intuitive hands-on operations and to concrete abstract abstractions; In discussing the exchange of internalization algorithm, in the practice of practice to consolidate the algorithm; to promote the diversity and optimization algorithms to guide students to conduct deep thinking, to provide students the opportunity to exchange, diversification of algorithms, seeking more Jane, Preferred and use.
