How does handwriting instruction affect beginning readers?

Handwriting instruction plays a significant role in reinforcing letter shape, which is crucial for beginning readers. When children engage in handwriting practice, they become more familiar with the distinct forms of letters. This familiarity is essential as it aids in their ability to recognize letters visually when they encounter them in print.

Reinforcing letter shape through handwriting helps establish a foundational skill that is necessary for reading. When children can accurately form letters, they are better equipped to decode and recognize written words. This process is linked to the development of phonemic awareness and letter recognition, both of which are vital components of early literacy.

While other aspects such as memorizing sight words, developing critical thinking, and improving reading aloud skills are important in a child's literacy development, the specific impact of handwriting instruction is primarily seen in its ability to solidify the understanding of letter shapes, making option B the most relevant choice in this context.
