People don't like memorizing algs. How do I teach those people how to solve? Ryan Heise's method is nice but I can't figure out the commutators. Help!
How to teach solving the 3x3 to others

No memorization
But those involve an alg

You can't solve it without any algs, unless you do Heise.

Yeah, and I don't believe any person new to the cube could understand Heise
And alg is a sequence of moves. To solve the cube, you are going to have to do sequences of moves. Teach others the algs intuitively, so they see what the pieces are doing, and not remembering it by letters. Like anything, whomever you teach with need practice. Learning a couple sequences is next to nothing with practice.

cross and F2L can be taught intuitively but the LL algs cannot be.

Actually OLL can be taught by breaking up the F2L, moving LL pieces, restoring F2L.
It might be possible to do the same for PLL, only this time, you break up OLL and restore it.

I teach math at a junior high school, and I started an after-school Speedcubers club with my students. We have met only twice, but at the last meeting there were over a dozen students learning to solve the first layer (steps one and two of the Fridrich method). They followed along as I showed them a PowerPoint presentation I made for them, and I also used the document camera in my classroom as I demonstrated the algorithms for them.
They seemed really excited to be breaking the surface of the ice which is the mystery of a Rubik's Cube solve. I can tell that they just can't wait to be able to do it all on their own to impress their friends. I told them, "It is AWESOME being impressive. That's why I learned how to solve four sizes of puzzle cubes, sang lead in a band, became a magician, and memorized pi to over 500 decimal places." Lulz.

You can teach someone the LL with only 3 algorithms. I did this with my brother. You learn a sune, A-perm, and U-perm. The way I found worked to teach people the move, is to have them do the algorithm over and over, until it somewhat became muscle memory. Then I show them what the algorithm does, after the algorithm is already kinda learned. Taka's site works well for teaching, because it actually doesn't use letters, it just uses pictures for each move. You have to read over it before using it to teach because his english isn't very good. I found it works wonders for teaching someone to solve the cube, and then they can learn more algorithms as time goes on. It's better than learning the EO, EP, CP, CO beginner's method.

You dont even have to know the U perm. only Sune twice 
F2L can be learnd intuitivly. LL is: "FUR URF", "FRU RUF", "Sune" and A perm
wich only few people I tought it to, needed more than one day to memorize

I run into exact same problem... People get discouraged when I mention algorithms... however, theres also an intuitive way to do a 3cycle of edges, but im not sure how fast it is. Also, there is intuitive way to understand what happens in the SUNE... The corner 3cycle is the only one I dont have an intuitive way for...
for SUNE, i explain it something like:
you pop out an F2L pair, close the slot, rotate the top once, open the slot, and pop the F2L pair back to its place. Quite simple...
for 3cycle of edges:
cycles edges UB -> RB -> LB
pop out the F2L pair in FL, pop out F2L pair in FR, without destroying the first pair, then put back the first F2L pair into its slot, and lastly put back the second F2L pair into it's slot. The result is an edge 3cycle. Complete algorithm would be
(L' U' L) U (R U R') U2 (L' U L) U (R U' R')
also, its very easy to mirror that across the cube to produce reflection of it... since you do the same thing, but pop the right F2L slot first.
people like that much better than the idea of memorizing some arbitrary sequence of moves... what a bunch of lazy chickens most of them... pff
if anyone knows an intuitive way to somehow do a 3cycle of corners like that, please post that i'd love to know

I wouldn't say those are intuitive ways of doing it. They are ways to remember how to do it, not intuitive ways.

How about this for "minimal algs"
1 alg = R U R' U'
Edge OLL = F alg F' (correct edge (if any) at UL, incorrect edge at UF)
Corner OLL = alg*2 D alg*2 D alg*4 D alg*4 D (just an example, incorrect corner at FDR, repeat alg untill corner is correct, next corner)
Edge-cycles: M D2 M' reposition U (so H-perm would be M D2 M' U2 M D2 M' U2 M D2 M' U M D2 M' U2 M D2 M' U2 M D2 M' U')
Corner-cycles: R' D2 R reposition U (so A perm would be R' D2 R U R' D2 R U R' D2 R U2 R' D2 R)
If there is a parity error between edge and corner cycles this won't work. I don't know how to fix that without algs
You shouldn't think of the edge and corner cycles as algs. Just think of them as "take out an edge/corner, store it in a safe place, put it where it needs to be". I would call that intuitive!

i agree, it's really a technicality though... what i really meant to say is that it doesnt require you to memorize R U R' U2 ... whatever whatever, but instead just learn the logic of what you are doing, which is MUCH easier, i hope we at least agree on that.
and avGalen, that is an AWESOME way to do corner 3cycles... its genius, i really like it
thanks a lot for sharing.the corner OLL i dont really understand, it doesnt seem to work for me... i fix all the corners alright, but my entire cross is ruined as a result, i must be doing something wrong

You need the ones that orient the edges in LL too. And did you thaught them one a perm and one u perm or both A perms and both U perms?

I actually use this for corner-cycling on the last layer of the megaminxand avGalen, that is an AWESOME way to do corner 3cycles... its genius, i really like it
Try this:
Scramble = R U R' U R U2 R' (Sune)
Fix OLL = z2 (R U R' U')*4 D (R U R' U')*4 D2 (R U R' U')*4 D
I actually use this for corner orientation on blindfolded solves

Well I teach it this way:
1.Intuitive F2l
2.FRUR'U'F' for edge OLL.This is also pretty easy to understand and most people have no problem with this.
3.Sune for EP
4.CP with RU'L'UR'U'LU. This is very symmetric and so very easy to remember.
5.Commutator D'R'DR for CO
This way I feel is a fast way of teaching to solve.
Most of them whom I taught learnt it in less than 2.5 hours.

Petrus F2L is really easy to teach, so I don't use any special method for explaining it.
For teaching LL algorithms, I replace all of the F2L pieces with blanks so I only have LL pieces. I hang on to that cube and give the person I'm teaching a normal cube, since they'll be watching mine while I show them the algorithm. Usually I can fully teach any algorithm in less than 5 minutes. Of course, the only people I actually try to teach tend to be fast learners.
