Words are the building blocks for learning. Reading, writing, speaking, listening – all require vocabulary skills. Students can’t master math or science concepts without the ability to read and comprehend words – volumes of words. Virtually all subjects taught in schools today (from Pre-K to 12th grade) require specific vocabulary knowledge for achievement of any content. Research supports the need for explicit vocabulary instruction, and it also reveals that too many teachers are leaving this important instruction to random word exposure and daily encounters with assigned reading.
