We suggest solving directions for problems in the national curriculum related to electric current through comparing it with an American textbook. The most serious problem is in subject of “electrostatics”. The chapter for electrostatics in 7th grade should play a bridge role between “electric circuit” in 5th grade and “electricity” in 9th grade. We would like to explain why the concept of electric current should be introduced in “electrostatics” area and how the electrostatics chapter helps learning electric current. Also we are trying to point out that a closed circuit is very important compared to an open circuit. Finally, some points, such as metal in triboelectric effect, role of battery, and separation between conductor and insulator will be discussed.
