中职学生抽象思考意愿低,学数学效果很差.为此,基于学校招生数据分析案例,从学生感性认识入手,利用数列和函数在内容上有很强的相关性的特性,设计应用教学案例.通过5个递进的问题,重组数列和函数的知识点教学顺序,引导学生从认识生活逐步进入数学学习,避免孤立地学习抽象的数学知识,有助于降低学生对数学的排斥心理,不知不觉地从数列知识学习中自然过渡到函数知识的学习.当前数学教材中,函数放在第三章,数列是第六章,两章内
Therefore, based on the school admissions data analysis case, starting from the students’ perceptual knowledge, this paper makes use of the characteristics that the sequence and the function have strong correlation in the content, and designs the application teaching case Through the teaching sequence of five progressive questions, the reorganization sequence and the knowledge point of function, the students are guided from the cognitive life to the mathematics learning step by step, to avoid learning abstract mathematics knowledge in isolation and to reduce students’ rejection psychology. Unconsciously from the sequence of knowledge to learn the natural transition to the function of knowledge in the current mathematics textbooks, the function on the third chapter, the sequence is the sixth chapter, two chapters
