针对目前数学教学,想到有些问题有深入探讨的必要,诸如怎样正确领会教学大纲与课本的基本精神来确立教学目的;怎样加强基础知识教学和培养灵活运用能力;怎样才是根据学生实际进行启发式教学等等。现仅对初三的二个课题:“|x|a型的不等式及其解法”与“一元二次不等式及其解法”等,谈谈几点看法。一、认真领会大纲与教材的基本精神。首先要明确每章或每节教材的地位、作用与承上启下的关系,如含绝对值的基本型不等式对今后研究代数函数性质,曲线范围,极限概念、三角函数以及求阶梯函数的零点和正负区间
For the current mathematics teaching, it is necessary to inquire into some issues, such as how to correctly understand the basic spirit of the teaching syllabus and textbooks to establish the teaching purpose; how to strengthen the basic knowledge teaching and training and flexible use of capabilities; what is based on the actual student heuristic Teaching and so on. Now we only talk about the second topic of the third year: “The inequality of ”x,a“ and its solution” and “the quadratic inequality of one yuan and its solution”. I. Carefully understand the basic spirit of the outline and the teaching materials. First of all, we must clarify the relationship between the status and role of each chapter or each teaching material, such as the basic type inequality with absolute value, to study the nature of algebraic function in the future, the curve range, the limit concept, the trigonometric function, and the zero and the positive and negative of the step function.
