Hi Allison
This is really easy to accomplish. You can use the "collector feature service layer" as a map for the App you create and configure it so people can see the data and get the information pop-up when they click on it but not edit the data.
At the same time you can use the same "collector feature service layer" with the students collecting/creating and updating data points, lines or polygons.
