Classroom scenario
Carlos is a bright, engaging student in Mrs. Wilson's 10th-grade Chemistry class. He is very social and can talk his way into (or out of) anything. He participates in class discussions and listens carefully to instructions.
When it comes to writing lab reports, however, he struggles. His Chemistry teacher, Mrs. Wilson, is surprised to see how many gaps there are in his writing after reviewing his first lab report since he clearly understood the lab activity in class and explained the directions verbally to his peers. She knows that Carlos also speaks Spanish. She had assumed he was fluent in English, but now she is beginning to wonder about her initial assumption.
