Results are mainly qualitative. For someone who is familiar with Tuubi there is no problems completing the tasks easily. That does not mean that Tuubi is good as it is, but that you can learn to master it. One open question is, how steep is the learning curve in Tuubi.
Subscribing to workspace
*User who has little experience on Tuubi may find Tuubi frustrating because it doesn't seem to be intuitive or familiar. Tuubi is somewhat misleading the user in some cases, like when new user tries to find workspace through search-function. Test user tried to find the workspace by using the common search-function (located upper right corner and also in the search-tab) instead going first to Manage Workspaces.
*Subscribing to workspace is straightforward, but doesn't look that from unexperienced user's point of view. When you try to search for a workspace the search-function does not work when you hit enter. Instead user needs to click the search-button.
*Search results are shown right below the search-field and there might be several other workspaces. Test showed that it is not easy to locate the search-result. Also the subscribe-button is placed down on the page which means that it is not shown to user unless he/she knows the location and scrolls down.
*Also test user had problems locating the newly subscribed workspace on her menu of workspaces.
Assingments
*Test user commented the placement of the buttons on the assignments. When returning assignment the buttons are located bottom of the page in the right corner. Therefore it is hard to spot. User didn't feel sure if her answer had been uploaded succesfully.
*Second test user commented that the grade is easy to miss when you read the feedback. It is not shown on the same page as the verbal feedback.
