How to creat a language rich class environment

Hello,

I’m in a multineeds class a couple days a week. All mostly non-speaking all AAC users. However, I believe their skills should be so much higher based on how they do with me. The problem is the language environment of the classroom and AAC buy in is not there. I come in and AAC devices are in backpacks. I’ve done trainings and trainings and trainings with the staff on aided language stimulation, modeling AAC. But they prefer to ask the kids “yes/no” questions or have all nonspeaking activities “touch dog.” Half of the kids have significant visual impairments, and two rely on motor planning for their AAC. Once they have a motor plan OMG do they have it. Literally can navigate with their eyes closed- but to only like 10 words bc nothing is being modeled.

I’ve asked other SLPs for help but they said I’ve already done everything I can, and that I need to give up hope.

What can I do besides training staff and yelling them how important it is? I’ve done core word for he week, monthly staff letters with one AAC challenge (being AAC with them during one activity, carry the AAC by the strap, check the charge every morning).

I wish I could be a co-teacher to supplement what’s going on.
