Reaction Reactor

A surprising statement drops. Students react using target expressions for shock, doubt, or sarcasm — the most convincing reaction wins the round.

Reaction Reactor generates a target expression or idiom, a contextual scenario where it applies, a definition, and a modelled example sentence. Two modes — A.R.T. (expression-first) and Keyword Catalyst (scenario-first) — let teachers approach the same content from different angles.

Reaction Reactor generates lexical content for teaching expressions, idioms, and functional phrases — the language people actually use to react to things that happen. Each generation produces a named expression, its definition, a modelled example in context, and a linked scenario that demonstrates exactly when a native speaker would use it.
