The statement 'Vocabulary is a constrained skill; teachers are able to teach every word they need to know' is true. Which option best reflects this idea?

• A. False
• B. True
• C. It depends on the student
• D. It varies by grade level

Answer: (B)

The main idea here is that vocabulary can be taught within a bounded scope, with a finite, high-utility set of words that teachers explicitly teach and support students to learn. In classrooms, teachers select core vocabulary essential for comprehension and communication, provide direct instruction on meanings, usage, and morphology, and give repeated, varied exposures so students internalize these words. With this targeted approach, students gain a functional foundation of word knowledge that supports understanding across texts, and new words can be learned through ongoing reading and explicit strategies (like using context clues or analyzing word parts) beyond that core set. This is why the statement is treated as true: the essential vocabulary needed to function in the curriculum can be taught within the instructional scope.
