What Makes an Essential Question?
can be overarching or topical, convergent or divergent.
Essential questions yield inquiry and argument -- a variety of plausible (and arguable) responses, not
straightforward facts that end the matter. They should uncover rather than cover (up) the subject’s con-
troversies, puzzles, and perspectives.
2) is thought-provoking and intellectually engaging, often sparking discussion and debate.
Essential Questions work best when they are designed and edited to be thought-provoking to students,
engaging them in sustained, focused inquiries. Such questions often involve the counter-intuitive, the
visceral, the whimsical, the controversial, the provocative. Is the Internet dangerous for kids? Are
censorship and democracy compatible? Does food that is good for you have to taste bad?
3) calls for high-order thinking, such as analysis, inference, evaluation, prediction. It
cannot be effectively answered by recall alone (or via a Google search).
Their aim is to stimulate thought, to provoke inquiry, and to spark more questions, including thought-
ful student questions, not just pat answers. They serve as doorways into focused yet lively inquiry and
research. They are intended to result in conclusions drawn by the learner, not recited facts.
4) points toward important, transferable ideas within (and sometimes across) disciplines.
study. Is history inevitably biased? What is a proof? Nature or nurture? By examining such questions,
5) raises additional questions and sparks further inquiry.
Thought-provoking essential questions are naturally generative. They lead to other important questions
within, and sometimes across, subject boundaries. For example: In nature, do only the strong survive?
leads to other questions and inquiries into human biology and the physics of physiology. What do we
mean by “strong?” Are insects strong (since they are survivors)?
Essential questions are intended to elicit a variety of plausible (and arguable) responses. Students are ex-
pected to provide reasons and evidence. Thus, teachers pose follow-up prompts; e.g., Why?, What’s your
reasoning? Who agrees? Who disagrees? What’s another way of viewing this?
7) recurs over time; i.e., the question can and should be re-visited again and again.

Over time, student responses become more sophisticated, nuanced, and well-reasoned.
