The senior mini-lessons are designed for senior students (17-18) looking to hone their authentic critical thinking (ACT), link subject knowledge to the real-world, and strengthen their university application profiles.
The mini-lessons enable all students to share the cognitive benefits of TOK without following the IB pathway, via 20 new stories every month.

The mini-lessons enable teachers to encourage authentic critical thinking, tutors to deliver meaningful PSE sessions, EPQ coordinators to kick-start projects, and careers departments to develop university and life skills.
We add 15 new mini-lessons and knowledge journeys to the padlets every month, so check back here regularly, and share freely with your faculty. See our definition for the subject areas here.

The key concepts
The key concepts are ideas of particular significance to us as authentic critical thinkers. As much as possible, we try to build our newsletter stories and mini-lessons around them.
Use the key concepts to scaffold your thoughts and ideas, explore opinions, and ask questions about knowledge across different subject areas, as we’ve done below.

In which subject area are we able to make the most certain claims about knowledge and understanding? Why does this variance exist? Does language allow us to be more certain about knowledge? Can certainty bring disadvantages in terms of our understanding of the world?

How does the nature of the subject areas differ in different cultures? Do mathematics and science transcend cultural differences? Do the arts deal with culturally universal concepts? Does the way we understand the world depend on the language we speak?

Which subjects are most and least affected by perspective? How do our religious and political perspectives shape our worldview? Do our perspectives determine our language use? What forms our perspectives, and should we seek to escape them?

How does power affect the way knowledge is produced within the subject areas? In what ways can language be used to consolidate power as ideas are communicated? How does political and religious power influence the way we understand the world?

Workshops to help you escape your echo chamber!
Our online and in-person workshops are practical, honest, and jargon-free. They help teachers and students of all levels develop their authentic critical thinking, and become more nuanced and objective navigators of the world.
