Interactivity refers to the ability of users to engage and participate actively with content, rather than passively consuming it. This concept is commonly found in digital media, such as websites, video games, and applications, where users can make choices that influence outcomes or experiences. In educational settings, interactivity enhances learning by allowing students to explore topics through simulations or quizzes. Tools like interactive whiteboards and educational software promote engagement, making the learning process more dynamic and effective. Overall, interactivity fosters a two-way communication channel between users and content.
