自制教具是一种有创意的活动,是一种需要智慧和灵气的活动。教材的很多内容,需要我们教师具备这种自制教具的能力,即用有特色的自制教具去满足学生实验的需要,吸引学生去探究。化学实验在整个化学教学中占据着举足轻重的地位,在化学实验的教学和学习中,画仪器和装置图是不可缺少的一项,为此,我设计了一种能帮助教师和学生标准、快速地画出仪器和装置图的工具——化学仪器尺。
Homemade teaching aids is a creative activity, an activity that requires wisdom and aura. Much of the content of teaching materials requires our teachers to have the ability to make such self-made teaching aids, that is, to use special homemade teaching aids to meet the needs of students’ experiments and to attract students to explore. Chemistry experiments occupy the pivotal position in the whole chemistry teaching. In the teaching and learning of chemistry experiments, drawing instruments and device diagrams is an indispensable item. Therefore, I have designed a system which can help teachers and students to standardize and quickly A tool for drawing instruments and devices - chemical instrumentation.
