Which of the following factors is most likely to influence a student's reading fluency?

The most significant factor influencing a student's reading fluency is regular practice of reading. Reading fluency is defined as the ability to read text smoothly and accurately, with appropriate expression and speed. Regular practice helps students develop automaticity in word recognition, which allows them to read more quickly and with better comprehension.

When students engage in consistent reading, they encounter a variety of vocabulary and sentence structures, which aids in building their language skills and ultimately enhances their fluency. This practice also allows them to improve their decoding skills and increase their confidence in reading, leading to a more enjoyable and effective reading experience.

While classroom behavior, access to technology, and parental involvement can play supportive roles in a student's overall learning environment, they do not directly address the core skill of reading fluency in the same way that consistent practice does. Therefore, regular reading practice stands out as the most potent influence on improving a student's ability to read fluently.
