Joseph Martinelli gave a presentation on integrating Google Drive into teaching. He outlined the benefits of using Google Drive, including easy file creation and sharing, accessibility from any device, version tracking of documents, and collaboration features. Google Drive allows teachers to provide feedback to students and track changes in their work. It also connects to other Google apps like Docs, Slides and Sheets. While online collaboration through Google Drive has advantages like bringing people together remotely, it can be challenging to discuss projects in real-time without face-to-face meetings.
