EEs have for many years been taught "Conventional Current Flow",& have a bad reaction to the very thought of "Electron Flow".
That said,ejeffrey is right-----most of the time,electrons (or holes,or whatever) don't come into it!
Inside active devices,like Vacuum Tubes,BJTs,& FETs charge carriers are important,& help in understanding of their operation,but most of the time,current can just be regarded as a thing in its own right,without delving into how it works!
For instance Ohms Law works with Voltage,Resistance & Current as "things".
