板书作为组织教学中的一个环节,是教师上好课的必要条件。如果不重视这一教学环节,无疑将影响教学效果。 成人由于工作、生活等诸多因素的影响,机械识记能力有所下降,但它们具有较强的比较能力和综合分析能力,乐于将前后知识在整体比较和系统分析中去记忆和掌握。也就是说,成人习惯于理解地记忆问题,而简明清晰、重点突出的板书就有助于他们理解问题,从而帮助他们辨认和记忆知识。据心理学实验表明,人们从听觉获得的知识一般只能记住15％,从视觉获得的知识一般却能记住25％,听视结合起来可达到60％,而不是40％。若教师在授课时能将直观形象,鲜明生动的语言与安排适中的板书结合起来,就能获得较好的教学效果。但我们有些教师上课时,只念讲稿,不顾板书,一次课下来,要求学生掌握的知识很多,可黑板上却只有几个阿拉伯数字。试想一下,人脑的信息存贮量远不如电脑,当我们向电脑输入变量时,若变量较多还得想想办法,比如 As a part of organizing teaching, writing a blackboard is a necessary condition for a teacher to take a good lesson. If you do not attach importance to this teaching, will undoubtedly affect the teaching effectiveness. Due to the influence of many factors such as work and life, adult learners’ ability to learn mechanical skills has declined. However, they have comparatively strong ability of comprehension and comprehensive analysis. They are willing to remember and grasp the knowledge of the whole body and the systematic analysis. In other words, adults are accustomed to understanding memory problems, while simple, clear, focused, written help helps them understand problems and helps them to recognize and remember knowledge. According to psychology experiments, people generally get 15% of the knowledge they get from hearing, 25% of their knowledge of vision, and 60% rather than 40%. If teachers can combine visual images, vivid language with well-arranged plank in teaching, they can get better teaching results. However, when some of our teachers are in class, we only read lectures and disregard the writing. Once the class is down, we need a lot of knowledge from our students. However, only a few Arabic numerals are available on the blackboard. Imagine, the amount of human brain information storage is far less than the computer, when we input variables to the computer, if the variables have more to think of ways, such as
