数学是一个很抽象的、逻辑特别强的学科。正因如此,一提到数学,很多人满眼都是数字、符号、线条……满眼黑白世界,枯燥、乏味、繁难。特别是由于高中数学与初中数学相比,难度跨度太大,内容太多,教学进度又快。很多学生一下子适应不了,往往付出的时间、功夫很多,收效却很少,从而产生畏难心理,甚至消极放弃。因此,如何优化课堂结构,使抽象的认知活动变得简单而直观,使枯燥的数学课堂变得丰富多彩,使繁难的数学变得浅显易懂,使学生变得肯学、乐学,从而最大限度地提高高中数学课堂教学的有效性。这成了高中数学教师们亟待解决的问题。
Mathematics is a very abstract, very logical discipline. Because of this, when it comes to math, many people are overwhelmed with numbers, symbols, lines ... ... eyeing the black and white world, boring, boring, difficult. Especially because of high school mathematics and junior high school mathematics compared to the difficulty of span too much, too much content, teaching faster. Many students can not adapt at a sudden, often pay the time, a lot of effort, but little effect, resulting in fear psychology, or even give up. Therefore, how to optimize the classroom structure, make the abstract cognitive activity simple and intuitive, make the boring mathematics classroom colorful, make the difficult mathematics become easy to understand, make the students become willing to learn and learn, and thus Maximize the effectiveness of high school mathematics classroom teaching. This has become a high school mathematics teachers need to solve the problem.
