Since last presentation... Cognitive Walkthrough Refined prototype based on CW Usability studies  Professor Jacobson Professor Kay Professor Thornton Finalized prototype based on usability studies Working on final report

Cognitive Walkthrough Refine Prototype Usability Testing Project Progress Create Prototype   Interviews Cognitive Walkthrough   Refine Prototype Usability Testing Refine Prototype Final Report

Cognitive Walkthrough Each member individually conducted a cognitive walk-through based on our previous list of tasks. Each member noted problems he/she ran into and other HCI issues. Met as a group and decided on appropriate changes to make prior to usability studies. Refined the prototype based on the cognitive walk-through. 

Professor view Student pairing should be changed so professors don't have to manually type in name. (More on this later!) Migrated class settings from its own page to main page. Page is reloaded and automatically scrolled to class settings when a Professor adds a new class.   Project setup changed to a drop down menu for pairing deadline dates and automatic notifications rather than having several calendars. Setup evaluation added to the settings window. Back links passing proper information to previous pages to allow for easier web site navigation.  Changed Manage to Projects. (Manage and settings were too similar.) Image

Professor view Modified global navigation bar to have only "Home", "Help" and "Logout".  Initially we had place holders for other items we might want to add but this became confusing during usability testing. Added warning messages throughout site to help correct input and navigation errors.

Evaluation Creation/ Submission Problems Consistency - center and color all pages. Evaluation Creator Remove apply changes.  Just save and refresh. Decided not to -> evaluate after US.  Make title:"Evaluation Preview"  Student View Typing text should take away "evaluation saved."  When student added -> "Request Pending." Remove partner settings only allow adding of a single partner or solo.

Usability Studies Conducted in the professor's offices 15-20 minutes 5 tasks w/ different scenarios Screen capture software to record the scenarios Post-testing questions

Testing Problems Schedule conflict with Professor Pattis Database reset during testing with Jacobson. PC had performance issues during testing with Kay

Professor Jacobson Overview  Couldn't find where to disable individual work Went to Project Settings instead  Evaluation setup link was hard to find.  Looks like the page ends Manual pairing  ABC order Double click   Would use this program is available

Professor Kay Overview: Spacing for add projects Text box

Professor Thornton Overview: Placeholders were confusing -> disregard for entire bar No back button on Eval Creator page. Integrate all features into one main area. Windowing vs. Hide/Expand   There were many issues that were the same in both tests.

Student View Selecting and pairing students did not act the way desired.

Apply Changes Users all believed that apply changes meant that it saved the survey.

Calendars for Project Setup  

Statistics Change "Project Info" button to "Statistics" Although no professor actually had trouble finding it, Thornton said it was by process of elimination.

Changes Made Two ideas as solution to calendar problem. Idea 1 Idea 2 Changed 'Apply Changes' to 'Preview Changes' Spaced the Add Project section. (Added two lines)  Change the student view for pairing. Double Click Click and Drag Multiple Select - implemented Buttons Remove all the placeholders.

Student Usability Testing To be completed today with 4 ICS students (6pm ICS labs) -Testing the student view of the system. -Issues include: How to deal with different pairing options (applying for solo work, 1 partner, 3 person group exception). Evaluating 2 partners.

For Version 2.0 Use Javascript in order to allow a more fluid and client based user experience.  With C-Sharp, pages must be re-posted in order for changes to occur.  For example, selecting a date on a calendar requires a refresh for it to reflect the selected date and then another refresh to commit changes. Develop more dynamic statistics. Test two different versions of Project settings. Find out feasibility of integration into checkmate or EEE. Possibly develop a TA view.
