Many changes were made for this interface from feedback of the last user test, as well as some design decisions were made regarding refining and aesthetically enhancing several widgets.

In this interface:
* There is a login screen, where instructors could choose their name and program.
* There is a logout button which instructors can use to exit their personal space.
* The programs drop down menu has been shortened and separated visually from the Media Library button.
* Pages and page navigation were introduced in the Media Library.
* Images in the Media Library are labeled with the name of the file.
* There are new images for the Media Library button, the stage preview area and navigation buttons.
* The scroll bars are wider and moved right up to the edge of the screen.
* A delay has been introduced for activating a drag on images, to help reduce accidental dragging.

Through this user test we wanted to test if users could understand and successfully interact with the changes introduced in this interface. On a higher level, we wanted to find out how users would approach performing tasks in this interface with less guidance

We gave two users a short scenario, and simply asked them to prepare and teach a Water Chemistry lesson. They had the freedom to perform whichever subtasks they felt necessary, in whatever order they wanted to. After the task, we asked users follow up questions and did some participatory design.

* Users had no difficulties creating instructors, selecting programs and logging in.
* It was not apparent to one user she started in the Plankton station until she saw plankton images in the Media Library.
* Both users were able to switch stations to Water Chemistry easily.
* Users were able to bring up and dismiss the Media Library easily.
* Users could identify images easily by their labels, but at one point associated the label with the image below it, rather than above, due to the close proximity of the images.
* Users attempted to drag images to their group area before actually creating their first group.
* Users could easily rearrange and delete images.
* Users seemed to have no difficulties using the scrollbars.
* Users were able to present images easily by using the next and previous buttons, as well as tapping on images.
* We observed no difficulties with drags occurring when taps were intended.
* One user expressed that she found the random access capabilities of our application crucial when teaching each new group of students, as she may need to change the lesson on the fly.
* One instructor specifically requested for a way for new instructors to be started off with default groups – functionality that had already been implemented to meet a need as the content creators saw it.
