Zinc Reading Labs is not supported on Android tablets or devices at present. As we optimize the app for a tablet experience, we will update our support list.

Skills/Close Reading Experiences

  • Close Reading Experiences are not currently supported on iPads.

  • On the highlight exercises, some partially correct answers are being interpreted as incorrect.  For now, please offer your students encouragement that their responses are indeed valid.  We're working to make the app better at acknowledging variations of responses that are, pedagogically, acceptable.

  • On less current browser versions of Safari and Chrome, the app does not perform well (i.e. videos don't load smoothly or the simulation gets stuck altogether).  We recommend using the app on the most current versions of Chrome and Safari while the app is optimized for older browser versions.
