A few years ago I wrote a course for teaching assistants who supported students in (secondary) science lessons. The course was widely attended by colleagues from across our local authority. With the recent bad weather we decided to run a refresher course inhouse for our our own staff, since we have had quite a few new teaching assistants join our school in that time. The materials have also been modified slightly to give them a more generic slant rather than being science specific.
The presentation embedded below shows some of the strategies that teaching assistants can use with students in lessons, and the toolkit is a set of templates that can be used to support these strategies.
Feel free to download the toolkit/presentation and use them in your own establishment. I hope you find them useful.
