World History Commons

Teaming up with a leading educator, we design and implement tools that teach critical thinking.

Big Yellow Taxi partnered with George Mason University to create The World History Commons, an open educational resource designed for world and global history teachers, scholars, and students. This website offers over 1,700 annotated primary sources, 100 teaching guides, 30 overviews of methods and approaches, and 250 reviews of websites. To facilitate navigation, we organized the site into four main sections: Sources, Teaching, Methods, and Reviews. Each section can be filtered by region, period, and subject, and every resource is tagged to make it easy to find similar materials on any topic.
