Students Should Build Systems, Not Posters

Project-based learning becomes serious when the project has a technical burden: a system must work, fail, be tested, and be improved.

Too much school technology work ends with a display board about an imagined solution. Posters have their place, but they can also hide weak technical thinking.

A serious technology project asks students to build a system. It must accept input, transform something, produce output, survive testing, and make its limitations visible.

The classroom changes when the artifact has to work. Students stop asking what the teacher wants and start asking what the system requires.
