数列不仅在高中数学课程中,占有重要位置,在日常生活中也有着十分广泛的作用。同时,数列是培养学生观察、分析、归纳、逻辑推理以及运用数学思维分析问题、解决问题的重要途径。因此,如何做好数列教学设计是每位数学教师需要考虑的重要问题。文章根据数列单元的特点,涉及概念教学、技能训练和问题解决三个方面来考虑教学设计:一、概念教学(一)数学概念的引入,需要从实际出发,创设情景,提出问题如在数列的概念与简单表示法这节内容数列概念的教学中,对数列概念的引入,可以从研究书的角度提出数列概念,使学生感受到数列是刻画自然规律的基本模型;
The sequence not only occupies an important position in high school mathematics curriculum, but also plays a very extensive role in daily life. At the same time, the series is to train students to observe, analyze, summarize, logical reasoning and the use of mathematical thinking to analyze and solve the problem an important way. Therefore, how to do a good job of designing teaching in mathematics is an important issue to be considered by every mathematics teacher. The article considers teaching design according to the characteristics of sequence unit, including concept teaching, skill training and problem solving: I. Concept teaching (1) The introduction of mathematical concepts needs to set out the scenarios from reality, Concepts and Simple Representations In the teaching of concepts and concepts in this section, the concept of numbers can be introduced from the perspective of research books to make students feel that sequences are the basic models for describing the laws of nature.
