Heuristic | Severity Rating | Problem | Solution |
|---|---|---|---|
Learnability & Efficiency | Minor | In our Messages tab, users are required to select a conversation before writing a new message. Although a grey banner with "Select a conversation to the left" is displayed to inform users of this requirement, during testing, two of our users tried to click inside the message text area box to begin writing their message before they realized they first had to choose a conversation. One user commented that this threw her off a bit, and she felt like this may derail some teachers attempting to get their tasks done very quickly. | Although we attempted to provide instructions by placing a simple grey banner inside the message content pane, this was not sufficient for the users we observed in testing. Rather than requiring users to select a conversation themselves, a solution would be to have the top conversation (which contains all of the users that are selected on the left contact menu) automatically selected would indicate to users that a conversation must be selected to send a message. Because selecting a conversation selection causes it to be highlighted, this would give the affordance to users that they have to highlight a different conversation to select it. A negative effect of this solution may be decreased safety in sending messages, since users do not have to intentionally pick their conversation. |
Safety & Learnability | Major | Pressing enter in the text area for messages causes the message to be sent rather than creates a new line. While trying to complete a task, one user accidentally pasted the link she was instructed to send to the parents of several students and then pressed the enter key, which sent her message. She commented that she was trying to include some context with the link and the behavior of the enter key in our UI was not externally consistent with most other message UI's (e.g.: Gmail). | A solution to this problem would be to make the text area for messages more externally consistent by making the enter key create a new line rather than send the message. Although the original intention of making the enter key send the message automatically was to make messaging more efficient, we realized that some users who are familiar with other messaging UI's would also make these slips which decreases safety. |
Learnability | Major | The new message icon that is displayed on a user's row in the contact selection menu gives the affordance that clicking on it will direct the user to that new message. Two of our users tried to click on the message icon itself within a different context (i.e.: calendar, grades) to see the message. They said it was confusing that the message icon immediately went away after clicking on the corresponding row but the conversation was not selected, leaving users bewildered about what happened to the message. | The obvious solution to this problem would be to cause the new message icon to automatically direct users to the message context (despite what context they are currently in) and select the corresponding conversation, which would display the new message that the icon corresponded to. This would prevent users from getting confused over whether or not they missed or lost a message, and it would also make reading new messages much simpler and safer. |
Learnability | Minor Thinks | Conversations in the Message tab are displayed in groups according to the contacts that are included in that conversation. All conversations that a selected contact has been involved in (individually or in different groups) display in the conversation tab when that contact is selected. One user commented that displaying all of these conversations at once is being confusing. When more than a couple users are selected, the label of a conversation says the first couple of student names, then "+ X more" (with X being the additional number of selected students). All conversations also contain the icons of all the students selected. We received feedback that these icons are too small to identify who is in the conversation, and names would be less helpful than subject lines or some other label. the several conversations as being confusing: where names are no longer listed because of too many names, said shes not sure even with icons who is selected because they are so small (less helpful to identification, subject heading would be better) |

Efficiency | Minor | Having a way to automatically bring up a group of students under a title would be helpful |
|
Efficiency | Minor | Tried to send grade report without selecting SMS or Email (not internally consistent with messages, need to fix) Teachers time is very pressed, its good to have a simple layout and not have too much customization (SMS or Email, for example should already be checked), needs to be quick and simple |
|
Learnability | Major | the way conversations are displayed, labeled, scale them to how many messages have been sent, and sort them in a more intuitive way (would have expected to see most recent message listed first, not by people) Confusing to have the most recent conversations that person was involved in displaying , useful but not intuitive, make it more clear with a title or something |
