What type of technology can help parents keep track of their children's grades?

Online grade systems are effective tools for parents to monitor their children's academic performance because they provide real-time access to grades, assignments, and attendance records. These systems are often integrated with school databases, allowing parents to log in securely to view detailed information about their child's progress. This transparency encourages proactive engagement in their child's education and enables parents to address any academic concerns promptly.

The other options do not serve the purpose of tracking academic performance. Web cameras might facilitate communication or classroom observation but do not provide academic data. Television systems do not offer functionalities related to education monitoring. Home automation systems focus on managing household tasks and comfort rather than academic oversight.
