“Critical Thinking for Teachers” is a series of interactive radio programs and podcasts for teachers in rural areas of OAS member states. These audio programs strengthen teachers’ ability to teach critical thinking skills in mathematics, literacy, science, and citizenship education. Woven into an entertaining drama series, the participatory lessons feature short pauses that allow teachers to respond to questions, partake in group discussions, write plans for their classes, and more. Participants learn practical skills to apply in the classroom immediately. The primary audience is teachers with little Internet access who teach 11- to 14-year-olds, but any teacher can benefit and anyone can participate.
