The research tool within Google Documents is one of my favorite features for students. That research tool has been available in the browser-based version of Google Docs for years. Now that same feature is available in the Google Docs for Android app.
The research function in Google Documents allows students to conduct Google searches without leaving the Android app. When students find links, pictures, or quotes that they want to include in their documents they can simply tap the insert button to place it in their documents. For students who are using Android tablets or phones as their primary devices, the research function should make the process of writing research papers a bit more efficient.
