If you grade enough papers, you will find some consistent pitfalls, especially in the writing of students who are coming to philosophy for the first time. I wrote up the following tips a couple of years ago when I was a teaching assistant for an introductory philosophy class at Yale led by Daniel Greco called ‘Problems in Philosophy’. The tips were intended, then, for college students, many of them right out of high school, and most of whom had never written a philosophy paper before. So the focus is on clarity and mastering the basics. With that in mind, I hope you will find these tips helpful for teaching or writing in philosophy (or any other relevant field or discipline).
