CIRCUITS, CIRCUITS, CIRCUITS with large teams like that! Depending on the Level I'm working with I coach 7 - 14 at any one time. Now I'm lucky, I do usually have a high school helper when I'm working with the larger groups, but the quality of their coaching isn't as strong as my co-head coach and I. They just help make sure that the girls are staying on task.
Try and keep groups smaller than three as you circuit. That way when you do have the one-on-one group with you it can maintain that individual attention quality. More than that and you won't be able to get many reps out of your one-on-one group.
I VERY MUCH agree with CONSISTENT PROGRESSIONS, DRILLS and PATIENCE, but every now and again you need to throw that challenge ("carrot") in front of them. I just had a Friday Challenge practice last Fri, where for 30 minutes I let them try and sucessfully make the skill we've been drilling recently on a competition quality set up (i.e. high beam with one 8 inch mat for beam, no spot, etc). For every girl who successfully made that skill (it was determined by their level, last friday was front hip circles for 3's, kips & cartwheels on beam for 4's, r/off bhs tucks on floor for 5's, and twisting on floor for my optionals) we would build banana splits at the next friday practice. 1 scoop or ingredient for every girl that successfully makes (4 times) their challenge skill for that day. I had 8 girls out of 22 successfully make the challenge. So it will be an 8 ingredient banana split. I had one 1st time front hip, one 1st time kipper (WOO-WHOO! finally), three 1st time high beam cartwheelers, two 1st time r/off bhs tuckers (but they were pretty ugly-fugly), and one 1st time successful punch front layout full to stick - off tumbl trak.
I love the energy of these Friday Challenge practices, although we don't use our whole practice time for the challenge. It's the only day of the week we can loosely structure practices and use an open gym, self directed format. They abuse it... they lose it. It's a mandatory practice for our Level 5 and up's and by choice practice for our Level 3's and 4's. It seems to be helping with teaching desire and the determination to succeed. While of course I was proud of those who made these skills these challenges are also proving to be helpful for those who are either slackers or have mental issues in overcoming certain fears. When the more exerienced girls see those beginners tagging at their heels it's become quite motivating lately. I also have a very mental optional gymnast who hates the "feeling" and uncertainty of new things and just getting her to attempt twisting lately has been a chore. I was ecstatic when I saw her attempting back layout 1/2's off the tumbl trak last friday! She's more than capable and I was sure to share with her how proud I was of her attempts.
If you are from a large gym then it might be difficult to throw an open gym challenge such as that, but during a beam practice you might throw an incentive like challenge out like that. Popsicles, or no conditioning day, or walk to the park for conditioning (if you are close to one), condition the coach day, challenge the coach day,etc. these are things that have worked for me in the past as "rewards". I don't usually throw out a 100% reward, meaning if everyone can make their cartwheels then = reward, but rather an 80% or so, 4 out of 5 or 8 out of 10 girls. I do during season for routines sometimes. The challenge should be safe though. I wouldn't ask them to do something they are not capable of trying safely by themselves... minor beam bites don't count. Sometimes learning to crash on beam and then get back up because everyone else is still trying is necessary so they aren't quite so fearful.
Wow, that was more detail then I was planning. Don't get me wrong though, our usual practice structure is drill, drill, drill in circuits. We are in "open your mind up" mode right now, after a long details, details, details, competition season. Getting stronger and getting over fear, opening your mind up to new challenges and not setting limits on yourself. As summer training starts we will be working skills specific to the level they are striving to compete for the fall.
