What role does vocabulary instruction play in reading comprehension?

Vocabulary instruction plays a significant role in reading comprehension by enhancing understanding and providing the necessary words that enable readers to make sense of the text. A rich vocabulary allows readers to grasp the meanings of words and phrases within the context, which is essential for processing information, drawing inferences, and making connections while reading.

When students learn new vocabulary, they are better equipped to comprehend what they read, as they can recognize and understand key concepts, ideas, and themes. This robust understanding fosters deeper engagement with the text, leading to improved overall comprehension and retention of information.

Without sufficient vocabulary, readers may struggle with the text, miss nuances, or misunderstand the content, which can lead to confusion and frustration. Therefore, instruction that focuses on building a strong vocabulary foundation is crucial for effective reading comprehension.
