Which of the following is NOT a curricular resource to help teach digital citizenship?

Google Classroom is a learning management system (LMS) designed to streamline assignments, communication, and collaboration in an educational setting. While it can be used to deliver digital citizenship lessons, it is not a curriculum or a resource specifically designed to teach digital citizenship content itself. In contrast, Applied Digital Skills, Be Internet Awesome, and Common Sense Media are all established curricular resources that provide lessons, activities, and materials directly focused on teaching various aspects of digital citizenship, such as online safety, privacy, media literacy, and responsible online behavior.
