Vizor offers great tools for creating interactive 360 imagery. I've previously covered their Patches program for creating animated VR because that was the free service that they offered. Now their core product Vizor 360 is available for free too.
Vizor 360 lets you upload a series of pictures and then stitch them together. After you have stitched your pictures together to create a 360 image you can then add interactive elements to it. Those interactive elements can be links to websites, audio, and additional text and image overlays. A completed project can be viewed and interacted with in a web browser and or a VR headset.
Applications for Education
Vizor 360 could be a great tool for students to use to create interactive imagery of places that they have visited as part of a class or school field trip. Adding interactive elements to the imagery enables students to link to Google Docs they've created about the imagery and or to include audio of themselves talking about the imagery.
