How can you offer a class and not already have a curriculum outlined and ready to go?
As has been asked, are you dealing with total newbies, curiosity crazies, or folks that already have some reasonable knowledge & skill sets? Too, what area of Magic are you going to deal with?
If you have newbie then it's easy; you give them a good cover-all course. If I were doing it I'd simply include the Mark Wilson course as the primary Text and walk through it from point A-B. On the other hand, you may have some learned pupils that want training in key areas, which can be a huge snag; no one knows everything and no one excels and has solid performing experience in more than two or three key arenas (at least, if they are going to be good at it that's the case) In other words, we can only teach what we know, so what do you know. . . I don't mean the basics, I mean hard knowledge. . . let me explain. . .
If I were doing a class on Grand Illusion I wouldn't just cover "The Sawing in Half" and show them the evolution of the effect from Sielbit to Stinemeyer, I'd take the time to show them the nuances when it comes to design, deception, practicality of the system and what the trade-offs are between a cabinet built of Owen vs. one made by Abbott's and so forth. Same with the Asrah, there's dozens of different ways of do accomplishing this effect and while most have the same basic gimmick, there are still major differences. At one point I owned 6 completely different Asrah forms that could be used in different settings and/or give me a different kind of vanish.
This is something all instructors (good teachers) will weigh be it a talk on the Cups & Balls or a demonstration on Alternative Energy systems.
I have what most consider to be "vast" knowledge on magic but the truth, if we break things down, is that I really only know two key areas; big illusions and mentalism. I have some experience doing close-up, escapes and of course "Bizarre" type magick, but they really aren't my area of strength (though I do have a strong connection to the Bizarre) but I do not feel that I'm qualified to actually "teach" anything even remotely in-depth and informative in those areas. Granted, I'm picky and maybe expect too much of myself or those I seek to learn from, but it's likewise my comfort level and to some degree "ego" -- I don't want to be seen as the professor that can't answer the questions or who is overly disorganized.
I'd suggest you slow down and create a game plan first.
