I would have to get back to you on specific issues around public schools. My personal experience is more at the academic level, but I have been working on a project to look at the subject heading front and to look at implementing systems to access materials through indigenous languages, so we're supporting multilingual systems.
We know software often doesn't come out of the box all the time as multilingual, so it's important, too, to advocate for software.
Also, I will say that it's also important to connect, through our member associations, with other initiatives at the international level that are supporting indigenous knowledge and languages as well.
Part of it is supporting the availability of materials and the purchase of materials in indigenous languages, but it's also making them accessible through the means of the language. There are numerous projects. I would be happy to connect you with some of those resources.
