Thinking about the learning
The incorrect idea here is that the charges all originate in the battery and flow out from the battery to form the electric current.
Thinking about the teaching
The charges originate in the circuit itself and are set in motion by the battery when the circuit is completed. They are simply parts of the atoms that make up the battery, wires and bulb. You might think about it as if the charges
live in the wires.
