The Electronic Resources and the Published Resources will give you hundreds of ideas and research-based materials. Some of the books may need to be ordered or maybe you can borrow them through a local library, but others are in a PDF format and can be downloaded.
And, in the Published Resources section, I especially recommend the action research report Hardwired for Hope. Here is the report from a group of B.C. practitioners who took on an action research project asking: “What makes a great ABE teacher?” The findings may surprise you. They end that report with recommendations on “What to look for
when hiring an ABE instructor.”
