电路实物连接图具有直观性(是实验的写真图)而又接近于抽象(不显示真实效果),电路知识的学习由此入门。以下就这一入门知识的教学谈些初浅体会。注意循序渐进电路实物连接图作为学习电路的起始课,在教学内容的编排上要注意循序渐进,逐步发展学生的思维,欲速则不达。以并联电路的教学为例。初中第二册课本19页用图1-9(见本文图1)引入新课是不太有
The physical connection diagram of the circuit is intuitive (it is an experimental photo) and close to abstract (does not display real effects). The circuit knowledge learning is thus started. The following is a brief discussion on the teaching of this introductory knowledge. Note that the step-by-step circuit physical connection diagram is used as the starting point of the learning circuit. Attention should be paid to the gradual and gradual development of the teaching content, and the students’ thinking should be gradually developed. Take the parallel circuit teaching as an example. The junior high school second volume textbook page 19 is not very useful for the introduction of new courses with Figure 1-9 (see Figure 1).
