A teacher would like to improve communication and discussion between teachers and support staff. What is the most appropriate tool to fulfill this need?

Google Groups is the most appropriate tool because it is designed for facilitating group communication and discussions. It allows for the creation of online forums where teachers and support staff can easily post questions, share ideas, and engage in ongoing conversations on various topics, all within a centralized and accessible platform. Option A, Google Sites, is primarily for creating websites and sharing static information, not for dynamic discussion. While it can host documents and contact forms, it doesn't offer a direct, interactive discussion forum. Option B, Google Sheets, is a spreadsheet tool for organizing data and is suitable for meeting minutes, but it does not facilitate ongoing, multi-threaded discussions among a group.
