随着现代科技的不断发展,数学也在众多领域得以广泛应用。根据培养既掌握理论知识又具备解决实际问题能力的中专生的要求,我们的教育不仅要使学生获取知识,更重要的是要教会学生应用知识。笔者通过应用数学的教学实践谈几点体会。一、介绍建模的方法,培养学生的应用意识我们将实际生活中的素材引入教学内容中,使学生印象深刻,且有助于学生对知识的应用。例如,在“指数模型的建立”中,可以引入这样的问题:例1,经普查1987年中国人口为10.62亿,年增长率为0.9%,设此增长率不变,试建立 x 年后中国
With the continuous development of modern science and technology, mathematics is also widely used in many fields. According to the requirements of training secondary school students who possess both theoretical knowledge and practical ability to solve practical problems, our education not only requires students to acquire knowledge, but more importantly, to teach students to apply knowledge. The author through the application of mathematics teaching practice talk about some experience. First, the introduction of modeling methods to develop students' awareness of the application We will be the actual life of the material into the teaching content, so that students impressed and help students apply knowledge. For example, in the “establishment of exponential model”, we can introduce the following questions: Example 1: According to the census, China's population was 1.062 billion yuan in 1987, an annual growth rate of 0.9%. Let this rate of growth be constant and try to establish x years After China
