长期以来,中师化学教学普遍存在重知识传授、轻能力培养,特别是轻表达能力培养的问题。由于学生平时缺乏必要的训练,相当数量的学生不善于口头表达,也不善于书面表达。他们对实验现象的描述往往抓不住中心,对物质的制备、鉴别,常常叙述不清,对推理题的回答逻辑混乱。这种状况不改变,很难培养出合格的小学教师。为了提高学生的表达能力,我在中师化学教学中采取了下列措施: 一、以身作则,以简练、明白、准确、生动的表达给学生作出示范。课前我总是精心地作好教学设计,以便课上能用明白易懂的语言、有条不紊的板书,将知识传授给学 For a long time, there are many problems in chemistry teaching in middle school, such as knowledge transfer, training of light ability, especially ability of light expression. Because students usually lack the necessary training, a considerable number of students are not good at oral expression, not good at writing. Their description of the experimental phenomena often can not grasp the center, the preparation of the material, identification, often narrative, the reasoning logic of the answer confusion. This situation does not change, it is difficult to train qualified primary school teachers. In order to improve students’ ability to express, I have taken the following measures in chemistry teaching in Normal School: First, set an example for students to demonstrate with conciseness, clarity, accuracy and vividness. I always make elaborate teaching design before class so that I can use the language that is easy to understand and methodical to teach knowledge in class
