Current Issues
Our flagship program: weekly, single-topic deep dives into real, pre-censored news, designed to build critical thinking and reading comprehension.
Current Issues is a clear, well-run course that keeps our girls genuinely interested. Ardent trains our teachers and guides them every step of the way. It's a wonderful way for our students to learn what's going on in the world, without them getting information in ways we don't want them to.
THE FLEXBOOKTM
Some curriculum developers say goodbye at checkout.
We pull up a chair.
No two classrooms need the same thing. A class of five students reading two grade levels behind needs something different than a room reading on rollerblades. A teacher with limited prep time needs something different than one with a dedicated curriculum coordinator.
The Flexbook option accounts for that discrepancy with content that scales up or down, lessons that stretch or compress, structure that holds even as the specs shift.
Introducing The Flexbook, the flexible textbook, by Ardent.
All of our textbooks are also available as a custom project. It's good enough as is, but if you want to customize, you get a flexible framework and a feedback-friendly team ready to work through every page, every addition, and every adjustment your classroom needs.
The Flexbook.
We're open to revision.
