A successful SDAIE strategy that I have seen implemented in the classroom that I am in, as well as have seen in other classrooms I have observed, is the use of a word wall for explicit vocabulary development. Just having the word wall up with new vocabulary words and pictures is one way, however the way that I have seen it most successful is when these vocabulary words are constantly referred to during lessons, and students direct their attention over to the wall so that they know where the resource is when they need it. Having this as a constant reference during lessons, relates topics from lesson to lesson and reinforces new words so that students can understand and use them.
Another successful strategy that has been used in my classroom as well as other classrooms I have observed, is the use of think-pair-share activities. This has been particularly good because students who are native English speakers can help those students who are learning English to understand new concepts that they might be struggling to understand. Allowing the students to discuss and make sense of concepts together, and then encouraging them to share, either in a class discussion or through a demonstration of understanding by doing a problem, helps them to understand and apply concepts.
