Which of the following is NOT a component of metacognitive skills in reading?

Being unaware of text structures is indeed not a component of metacognitive skills in reading. Metacognitive skills involve the awareness and regulation of one's own cognitive processes, especially in the context of learning and comprehension.

Effective readers actively engage with the text, recognizing how they read and understanding the structures of the text itself. This encompasses taking an active role in understanding the content, being aware of various reading behaviors—such as monitoring comprehension—and relating new information to what they already know, which aids in deeper understanding and retention.

In contrast, a lack of awareness regarding text structures could hinder the reading process, as it prevents readers from effectively navigating different formats and genres, ultimately impairing comprehension and critical thinking skills. Thus, option C appropriately captures a non-component of metacognitive skills, as effective reading necessitates an awareness of these structures.
