A significant shortcoming of the Three-Cueing Systems model, compared to the Four-Part Processing Model, is that it obscures the role of which process?

The Three-Cueing Systems model primarily emphasizes context, syntax, and semantics as cues that support reading. However, this model tends to overlook the critical process of phonological processing, which is essential for accurately decoding words and understanding their sounds. Phonological processing involves the ability to recognize and manipulate sounds in language, which is foundational for reading fluency and decoding skills.

In contrast, the Four-Part Processing Model encompasses phonological, orthographic, semantic, and context processing, providing a more comprehensive picture of how skilled reading occurs. By recognizing the importance of phonological processing, the Four-Part Processing Model allows for a better understanding of the relationship between sounds and letters, helping to build a stronger foundation for reading development. Therefore, the significant shortcoming of the Three-Cueing Systems model lies in its inadequate representation of phonological processing, which is crucial for effective reading instruction.
