从近几年的高考题目来看,数学试题呈现基础化趋势,一些试题源于课本,又高于课本。这无疑是对教师教学导向的一种暗示,即狠抓课本、深入研究课本、挖掘隐含在课本中的数学思想和潜在价值,通过对课本的研究培养学生的数学思维品质。如何恰当运用、不断挖掘教材中例题、习题的多种功能,深化例题、习题教学,发挥其内在潜能以培养高素质的学生是摆在教师面前的新课题。一、重视课本例题的示范作用教科书中的例题一般都是在讲述了某个概念和命题后给出的,其
In recent years, college entrance examination examination questions, the basic trend of mathematics presents a number of questions from textbooks, but also higher than textbooks. This is undoubtedly a hint to teachers ’teaching orientation, that is, pay close attention to textbook, deeply study textbook, dig mathematical thought hidden in textbooks and potential value, and train students’ mathematical thinking qualities through textbook research. How to use it properly is a new task before teachers in tapping into the multiple functions of examples and exercises in teaching materials, deepening the teaching of examples and exercises, and exerting its inherent potential to cultivate high-quality students. First, pay attention to the exemplary role of textbook examples The textbook examples are generally given after the introduction of a concept and proposition, its
