How can Google Hangouts enhance classroom collaboration?

Google Hangouts enhance classroom collaboration by allowing teachers to collaborate and lesson plan effectively. This platform facilitates real-time communication and interaction among educators, regardless of their physical locations. Teachers can conduct virtual meetings to ideate, share resources, and devise strategies for presenting lessons to their students. This collaborative environment encourages the exchange of best practices and support among peers, leading to improved educational outcomes.

While creating group projects online can foster student collaboration, the primary focus of the option is on enhancing teacher collaboration. The option regarding replacing traditional textbooks is not relevant to the collaboration aspect, as textbooks serve a different purpose in education. Additionally, providing a platform for online quizzes does not encompass the broader collaborative functions that Hangouts can offer, which primarily center on communication and planning among educators.
