When internet service first becomes available in homes, the most likely change in students' behaviors is that the amount of time they spend studying drops, as do their grades.
Access to the internet can lead to increased distractions, such as social media, games, and streaming services. Many students may find themselves spending more time on these distractions rather than focusing on their studies, which could negatively affect their academic performance. However, it is important to note that this can vary depending on the individual student and their ability to manage their time effectively.
