一、教学背景二期课改以来,初中《科学》教材与《物理》教材中有许多相同的教学内容,例如测量、声音、力、热量、能量相互转化、电学等等,其中在电学部分尤为突出。九年级的物理教材中的电学基础内容全依靠七年级的科学教材中的电学内容,有的电学基础内容例如电路元件符号,电路基本连接方式及绘制电路 First, the teaching background Since the second curriculum reform, junior high school “science” teaching materials and “physics” teaching materials have many of the same teaching content, such as measurement, sound, power, heat, energy conversion, electricity and so on, prominent. The ninth grade physics textbooks are all based on the electrical content of science textbooks in the seventh grade, and some of the basic contents of the electrical components such as circuit symbols, the basic circuit connection and drawing circuit
