Ideas for improving Quran Classses

There has to be a way to reform the way we teach people (children) to read and memorize Quran.  Over the past ten years, we have tried at least half a dozen ways.  And each time we run into similar problems and complaints:
* teachers have a heavy foreign accent and the kids have a hard time understanding them.
* they sit around a table left to themselves for the majority of the hour (or hour and a half).
* they aren't given any tools to memorize except to read to themselves over and over.
* they get yelled at.
* they get compared to other kids in the class or to one of their siblings.
* other kids in the class are rude to my kids or just goof off because they don't want to be there either.
* my kids come back with headaches and whine for at least an hour before and after.
* the teacher takes phone calls or texts a lot during the lesson.

These are just a few complaints I have with the experiences we've had.  I'm so fed up with it.  I've tried incorporating memorizing Quran into our schedule, but it is much harder to follow through with it than you might think.  Talking to an experienced Quran teacher once, she told me that she sends her teen son to someone else to learn because it just doesn't happen at home. 

So I was thinking that maybe I could form some kind of format or suggested guide to improve Quran classes.  Since the teachers are usually volunteers with little experience in education or childhood development, they don't have the tools or resources to structure their class time with.  I'm no expert, but I have taken an early childhood development class, I've been homeschooling for over 3 years, and I read up about education as a hobby. 

Off the top of my head I would divide up the hour and a half into 25 minute clusters (or less) and do different things instead of expecting the child to sit for that long supposedly reading and memorizing on his own.  Other things I would suggest (and I might just think more on this subject and come up with a formal packet and present it)
* have a cheerful attitude.
* respect the child.
* take the age of the child into consideration including what skills he likely has and doesn't have.
* realize they are coming to you at the end of their school day and are likely a little tired.
* take advantage of multiple teaching methods: in pairs, have one student read along while another recites that sura from memory, then switch. 
* spend a few minutes actually showing them how to memorize and giving them tips and methods to memorize.
* realize that because they are young, you will want to repeat tips and instruction each time to drill it into them.
* set realistic goals.  or just set some type of goal instead of just showing up each time with no clear direction.
* show up 5 minutes before class starts so that you are there before the students. set the tone and get them busy as soon as they walk in with some type of warm up.

These are just a few of my thoughts.  I've been a little fired up about this topic (again) for a couple of days, and I really want to organize my thoughts so that I might present it to our Quran school.  I don't personally want to teach the classes, and I don't want it to depend on me; rather, I want a successful model to be used by all the teachers so that the students and families can have a better experience.
