Expressive language is about producing language to convey thoughts—speaking, writing, using vocabulary, and forming sentences. This item targets the area explicitly listed as a focus for fostering language skills, and expressive language fits best because it centers on how learners actively use language to communicate. Receptive language concerns understanding language, metacognition involves thinking about one’s own thinking, and semantic relates to word and sentence meaning; while all are connected to language, the emphasis here is on producing language to express ideas.
