Study description

Describe what participants will be doing in this study. Read our tips 

In this task, you will evaluate AI-generated explanations of high school and introductory college topics for factual accuracy, clarity, and educational appropriateness.

You will review AI explanations covering topics like:

"Explain the causes of World War I"

"How does photosynthesis work?"

"What is the Pythagorean theorem and how is it used?"

"Describe the structure of the US government"

"Explain supply and demand in economics"

For each explanation, participants will assess:

Factual accuracy (Are dates, names, formulas, and concepts correct?)

Completeness (Are key details missing or oversimplified?)

Clarity (Would a student understand this explanation?)

Potential misconceptions (Could this create confusion or incorrect understanding?)
