发展学生思维能力,是提高和发展学生诸能力的核心和关键。思维能力的形成和发展受诸多因素的影响。教学中,教师应善于抓住和利用影响思维形成和发展的各种因素。表述（口头表达与书面表达）能力是逻辑思维能力的一种具体表现;加强言语训练,是促进思维能力形成和发展的必不可少的教学环节。 学生获得的知识应能清楚地表达出来,并运用于实践才算完整的知识。中学化学教学中经常遇到学生不能准确地运用化学语言表达所学知识的现象。笔者在中考化学试卷分析中发现,问答题、鉴别题、推理题及计算解答题是学生失分较多的题。分析原因,除与学生本人对基础知识掌握不牢固有关之外,与缺乏表达能力也不无关系。 语言和言语这两个词在日常生活中几乎是通用的,但在科学上却有着严格区别,它们是两个不同的概念。语言是人类最主要的交际工具、思维武器;言语是人们运用语言进行的活动。人
Developing students’ thinking ability is the core and key to improving and developing their abilities. The formation and development of thinking ability are influenced by many factors. In teaching, teachers should be good at seizing and using various factors that affect the formation and development of thinking. The expression (verbal expression and written expression) is a concrete manifestation of logical thinking ability. Strengthening speech training is an indispensable teaching link to promote the formation and development of thinking ability. The knowledge acquired by students should be clearly expressed and used in practice to be complete knowledge. High school chemistry teaching often encounter students can not accurately use the chemical language to express their knowledge of the phenomenon. The author found in the analysis of the examination papers in the entrance examination, question and answer questions, identification questions, reasoning questions and calculation of answer questions is the problem of more students lost points. Analysis of the reasons, with the exception of the students themselves to grasp the basic knowledge is not strong, and the lack of expression is also not unrelated. The two words, language and speech, are almost universal in daily life, but they are strictly different in science. They are two different concepts. Language is the most important communication tool of mankind and thinking weapon. Speech is the activity that people use language to carry on. people
