图象对中学化学教学至关重要,据统计,在新编十年制全日制初高中化学课本中出现的图象计有273幅,其中实验装置图121幅,图表93幅,工艺流程简图47幅,模型示意图12幅,教师除充分利用教材中的图象外,同时还根据教材内容(乃至包括习题内容),自行绘制图形、图表,示意图象,将对化学教学起着积极作用。 下面就图象在化学教学和培养学生能力中 The image is of utmost importance to chemistry teaching in middle schools. According to statistics, there are 273 images appearing in the new ten-year full-time junior high school chemistry textbooks, of which 121 are experimental installations and 93 are diagrams. There are 47 models and 12 schematic diagrams. In addition to the teachers’ full use of the images in the textbooks, they also draw graphs, diagrams, and schematic diagrams based on the content of the textbooks (and even the content of the exercises), which will play a positive role in chemistry teaching. Here are the images in chemistry teaching and developing students’ ability
