I would just keep practicing and continually model what the expectations are. For example, ask some students to show you the "wrong way" (keeping on with the chit-chatting). Then, ask them to show you the correct way. Make a big deal about how it makes you so happy when ALL your students are following directions and ready to learn. Vary your voice, ping pong the score (back and forth) and celebrate when your students demonstrate the desired behavior. If you try to teach when a few continue to talk, they will not think you are serious about ALL students being ready. I only use Hands and eyes" when I am making a really big point. Otherwise, I use "Class, yes" (Probably 1,000,000 times a day!!!)
I have had my students participate in creating a t-chart for listening and speaking. We included, "What does it look like?" "What does it sound like?"
Also, when I feel myself tensing up or getting frustrated with the same behavior over and over from 2 or 3 students, I ask, "What is behind this? Is s/he tired, hungry, seeking attention?" You may want to set up a student conference to see if you can find out what is behind the actions.
Personally, I use the scoreboard until about October, then I add the practice cards. It really depends on my class. Last year, I didn't use the practice cards with my whole class, just with a few students who needed the card on the corner of his/her desk as a reminder. For one child, I ended up laminating the 5 rules and sticking them to his desk, with velcro on each rule. He had smilies with velcro on the back. He started each day with all smilies. If he needed a reminder, the smilie would come off until he earned it back. This child could not have handled frownies...he had severe anger and self- esteem issues. The beauty of the practice cards is that the behavior is associated with the rule, and not with the child's sell-esteem.
Don't despair!!! You can do it! The procedures and expectations you set up now will pay off!!
