Final answer:
Jeremiah exemplifies metacognition by strategically planning his study activities and reviewing challenging material, which is key to effective learning and language acquisition.
Step-by-step explanation:
Jeremiah's understanding that he needs to study his spelling words carefully to do well on his weekly spelling tests, and especially spend extra time reviewing words that he previously missed, is an example of gains in metacognition. Metacognition is the awareness and understanding of one's own thought processes. It involves self-regulation strategies like planning how to approach a learning task, monitoring comprehension, and evaluating progress toward the completion of a task. Jeremiah is displaying a conscious awareness of his learning techniques, which is important for effective studying and deep learning. His approach of extra review of previously missed words also reflects an understanding of the importance of semantic memory in acquiring language skills, which refers to the memory of meanings, understandings, and other concept-based knowledge unrelated to specific experiences.
