《数学课程标准》指出:“数学教学要紧密联系学生的生活实际,从学生的生活经验和已有知识创设情境,引导学生开展观察、操作、猜想、推理、交流等活动,使学生通过教学活动,掌握基本的数学知识和技能,初步学会从数学的角度去观察事物,思考问题,激发对数学的兴趣以及学好数学的愿望。”因此教学中采用多媒体并合理地运用,不仅有助于激发学生的学习兴趣,发展学生的想象能力,还能创设教学情境,有效地培养学生的数学能力。一、运用音乐、图形渲染数学情境在小学数学教学中,把音乐、图形与文字相结合,作用于学生的听觉与视觉,会起到相互补充、相互强化的作用。小学数学课本中的 The standard of mathematics curriculum states: “Mathematics teaching should be closely linked with students ’actual life, create situations from the students’ life experience and existing knowledge, and guide students to carry out activities such as observation, operation, conjecture, reasoning and exchange so as to enable students to pass teaching Activities, mastery of basic mathematical knowledge and skills, preliminary learning to observe things from the mathematical point of view, think about problems, stimulate the interest in mathematics and the desire to learn math. ”Therefore, the use of multimedia in teaching and rational use not only helps Stimulate students interest in learning, develop students ’imagination, but also create teaching situations, effectively cultivate students’ mathematical ability. First, the use of music, graphics rendering mathematical situations In primary school mathematics teaching, the combination of music, graphics and text, the role of the students auditory and visual, will play a complementary and mutually reinforcing role.
