The parent search is really a justification. Whether this helps at school, whether it counts for anything later and whether it is better than a screen at home is what gets typed, and a page that answers honestly is what converts a doubtful adult.
Teenagers search for themselves, and they search competitions. A league or a challenge typed by a thirteen-year-old brings a family who arrive already committed, which is a very different enquiry from a parent looking for an activity.
The vocabulary is scattered across four words. Coding, robotics, technology and STEM describe one wish, and a school that covers the whole set turns up for audiences that would otherwise never overlap.
Schools are a buyer with a budget. A teacher or a head of department looks for enrichment sessions, a club run on the premises or a workshop week, in language no parent would ever use.
