I teach 2nd grade ESL students. An idea that I picked up on here is giving sentence frames. When you do the teach-ok the students have the sentence frame to help them construct the sentences. I also realizd that it is important to have informaton up on the screen or on posters for the students to reference. It helps them to remember the words to use.
Since you have a wide range of students, pair up the more advanced students with lower ones. The students who are more fluent can be partner #1, and the sutdent who is less fluent can be partner #2. That way when you use the teach-ok the more fluent student goes first and the other can listen. You can also do mirror words where the partner repeats all the words that the first parther says. The teach-ok is awesome because it gives the students practice speaking in a "safe" environment and you can monitor understanding and make corrections as you walk around without having to put a student on the spot in front of the whole class.
There are so many great things about WBT for ESL students. Even just the
basic procedures are excellent practice. For example when we need to get something out of the desk, I will say something like "Please get out your blue reading book." And the class will respond, "Blue reading book, blue reading book, blue reading book!" Or I'll tell the class to sit on the floor and they will say "floor, floor, floor" as they move into place.
I also LOVE WBT for vocabulary. We make gestures for new words. Then to really reinforce the concepts, I will use the vocabulary to get the students' attention throughout the day. In said of saying class-yes, I will say "ancient" and they will say "ancient, VERY old" as they act it out. Instead of answering with the definition, you can also have them practice the words in context by having them repeat a sentence using the word.
I also love the new brain toys that I heard about on the livestream broadcast:
www.livestream.com/wholebrainteaching1 One idea is to teach the students to create complete sentences orally before they ever begin the writing.
One more idea- you might also use some of your more advanced students as student leaders who can help you monitor for correct speech during teach-ok.
Good luck!
