Say you teach students that:1♥-(1♠)-2♠ shows 11+ with a heart fit instead of 1♥-(1♠)-3♥ (which then can and will be used to show a weak hand with an extra fitting heart).
Even though they know this both students continue playing 1♥-(1♠)-3♥ as showing 11-12, even though both have agreed and discussed that the sequence will show a weak hand and the cue-bid the limit + hand.

In auction 1, why do you think a limit raise or better is inappropriate for an unpassed hand?
I too am a bridge teacher, giving classes to novices and beginners (sometimes intermediates as well). I teach them SAYC for two reasons –
1. It’s the least complicated to learn.
2. Some of those students go on to play on BBO where SAYC is the default system.
From the OP I can tell that Hanoi5 is probably teaching his students 2/1 who are familiar with SAYC. In the auction posted, SAYC and 2/1 differ substantially.
Some extracts from the SAYC booklet:
1M-3M = limit raise (10-11 HCP with 3+ trump support)
1M-4M = 5+ trump support, singleton or void, less than 10 HCP
COMPETITIVE BIDDING
Bids mean the same things they meant without the intervening bid [So if SAYC was being taught, then 3
♥ would still show the limit raise, despite the opposition intervention. The fact that your students keep bidding this way is probably an indication that they are familiar with SAYC].
Cue-bidding right-hand opponent’s suit
shows values for game without clear direction for the moment.
This is often used to show a game-forcing raise: e.g. 1
♠-(2
♣)-3
♣ =
game force; usually a raise.
Max Hardy and Steve Brunno’s book on 2/1 agrees with the limit raise except for showing 10-12 HCP (versus 10-11 HCP). Ok, so this book is old and bidding theory has moved on.
Paul Thurston’s Pocket Guide to 2/1 is more modernized. Using this as a reference then:
1M-2M = 3-card raise 7-10 HCP
1M-3M = 4(5)-card pre-emptive raise, less than 7 HCP
1M-4M = 5+ card support, less than 10 HCP, singleton or void (same as SAYC)
Paul uses Bergen raises to show the in-between raises with 4(5) card support. To show a 10-12 HCP and a 3-card limit raise, he goes via 1NT and then a jump to 3M. With GF values, responder’s first bid is obviously a 2/1 bid.
When the opponents overcall,
the cue-bid raise is used to show 4+ card support and limit+ raise (includes the possibility of GF strength). An exception to this rule occurs when responder has
a limit raise but only 3-card support. A negative double followed by a raise to 3M shows the limit+ raise.
SAYC and 2/1 have a lot in common. My suggestion to you to fix this problem is this:
Compile a conversion table from SAYC to 2/1. You might be pleasantly surprised to see how little actually changes from SAYC to BASIC 2/1. Obviously the more conventions you start adding on increases the complexity.
Good luck. I have a full understanding of your frustrations!
