The purpose of this article is to identify, from the plethora of journals dedicated to publishing research in the field of mathematics education, in general, and from mathematics education's 'Group of Seven', in particular, what I call the Math Ed Majors. In order to do so, I look to men's professional golf, and men's major golf championships. Worthy of note, there are only four majors in men's professional golf. As such, I pronounce only four journals as math ed majors. Recognizing that I may ruffle some feathers, I take into consideration, as has been done in men's golf, scenarios where there are only three or perhaps five majors. Also taking into consideration that I am constantly on the lookout for and have a vested interest in Canadian mathematics education matters, because if Canadian mathematics education matters then Canadian mathematics education matters, I provide an honourable mention by drawing parallels between a prominent journal and the Canadian Open. After a bit of translation, necessary for a brief aside where I speak Canadian, I allude to Part II of this manuscript, proclaiming the Math Ed Majors with the explicit purpose of introducing brand-new, unconventional, professional golf-based author productivity indexes.
