Adobe Spark is basically Adobe's answer to Google Apps
The Spark apps are assumed to be used online only, they're web based and rely on a vertical scroll mechanic in two of the three variations: Adobe Page, and Adobe Video. The artefacts they can produce are very impressive, way beyond anything students can create in Google Apps, BUT without the powerful tools for engagement like Google Doc comments, collaboration etc.
So if your priority is collaboration and online feedback/peer assessment then stick with Google Apps. If your priority is an impressive final artefact then you might want to give Adobe Spark a try.
The three Spark apps provided really on a vertical scroll mechanic in all three variations: page, posters, and video. For this reason they are mainly designed for online viewing only, there is not option to download/print any of these artefacts. The exception is Adobe Post which uses templates and a built in image library to create posters, like Pic Collage or Canva.
Adobe have collated some examples of all three types here, also examples focused on education.
If students try to access Adobe Spark directly they will be unable to access unless they are over 13 years of age . Fortunately we have EDU access to Adobe apps, which means anyone under the age of can use, once IT have enrolled them.
IT have set up most of this already using each student's college gapps email address. Each student will have received an email inviting them to join and create an Adobe account*, they can use that link to finalise the account by creating a suitable password.
Then click the big blue + icon at the top of the page to get started...
*Note
They can use their school password IF they included a symbol when they created it, most will not have done this, so I suggest they just use their college Google Apps account password with an @ at the end.
Create a password to use with your Adobe account
Click through to Creative Cloud
Click the Apps tab, and scroll down to Adobe Spark
The Adobe Spark apps can also be used on an iPad as separate (free) apps, students will need to follow the same process described above to create an Adobe account.
If all else fails, they can always click 'forgot password' to set a password to use, to do that they will need to visit this URL: http://accounts.adobe.com/
They can also just search for 'adobe id' and click 'adobe id forgot password' from the list. The first link should be the adobe site, where there is a link to the above page to reset. They enter their email address, and they will receive an email with a link to create a new password....
