When doing calculations involving current flow it really doesn't matter what the direction is as long as it is consistent. So the modern convention is current flows from the positive source terminal to the negative source terminal.
The direction of electron flow is unimportant for electronics calculations using electronic engineering equations (Ohm's Law, parallel/series components, Kirchhoff's Laws, etc). It is only important when you are working with the Physics or Chemistry that involves electrons/holes. In the field of Electrochemistry the positive/negative convention is reverse from that in electronic engineering.
