Teacher's field guide

What Students Need to Do: Students judge whether questions about saving and sending digital information can be answered with evidence. They compare benefits and drawbacks using measures such as file size, error rate, cost, and access during an outage.
What Mastery Looks Like: A student can turn 'Is cloud storage better?' into a question about how long it takes to retrieve files after a laptop fails. They can name the data needed and explain a trade-off, such as easy backup but no access during an internet outage.
Common Misconceptions: Students may assume digital files cannot be damaged or lost. They may also assume every digital copy keeps all the original detail, even when a photo or audio file has been compressed.
How to Assess It: Exit ticket: Rewrite 'Is cloud storage better than a USB drive?' as a question that could be answered with data. Name one measure to collect and one possible benefit and drawback of cloud storage.

Lesson moves

Pairs send eight-bit paper messages with and without a parity bit, then flip one bit and check which message reveals the error.
Ask students to rewrite 'Is emailing a photo better than mailing a print?' so the question names a measurable benefit and drawback.
Sort question cards, including 'Is cloud storage best?' and 'How many files survive a laptop failure?', into testable and vague piles.
Compare a printed school photo album and a shared folder for retrieval time, access during an outage, and risk of damage.
