Among education writers, the phrase “critical thinking” can run from nebulous notions to utter ciphers. Few will disagree that critical thinking is good and needed, but relatively few will agree about what it is in the first place. Colin Seale has not only written about critical thinking in more precise language but established institutions for developing critical thinking as a group of practices that teachers in different places can deploy for students of all kinds of ability levels. His recent book Thinking Like a Lawyer, soon to be released in a new edition, proposes a core set of classroom sessions that develop flexibility and power in thinking, and Christian Humanist Profiles is glad to welcome Seale to the show.
