  1. 1. OPTIMISING CHILDREN’S OUTCOMES (OCO) Technical Presentation
  2. 2. THE APPLICATION Apple iPad Application  Aim of the application is to monitor and manage classroom behaviour  Monitors  Students’ eye-contact with the blackboard  Noise levels of the classroom  Complies data into easy to read graphs  Allows teachers to examine class performance throughout the day  Each child will have a profile  Data from the App can be emailed to parents 
  3. 3. THE TECHNOLOGY Axure and Adobe Illustrator Axure  A wireframing, rapid prototyping and specification software tool aimed at web and desktop applications  Why we chose Axure Previous knowledge using the system  Creates detailed, realistic prototypes  Acts out user requests (buttons, type, etc.) 
  4. 4. Adobe Illustrator  A vector based graphics editor developed by Adobe  We will be using Illustrator to create graphics for our app  Why we chose Adobe Illustrator    Creates good quality graphics Strong knowledge with using the system Less restricting than other programmes, such as Photoshop
  5. 5. THE PSYCHOLOGICAL RESEARCH Eye-Tracking  A study examined student’s attention in class and gaze and focus patterns  Results showed students’ focused more on the blackboard than the instructor [1] Noise Levels  Studies have shown that high levels of ‘classroom acoustics’ can have an adverse effect on students’ academic performance [2]  Research illustrates that children’s performance at school including cognitive abilities such as memory and reading ability as well as motivation can be negatively affected by noise [3]
  6. 6. THE DESIGN PRINCIPLES (INTERFACE DESIGN) Nielsen’s Heuristics and Pressman’s Principles  How we plan to apply interface design rules to our prototype Nielsen’s Heuristics  They are called "heuristics" because they are more in the nature of rules of thumb than specific usability guidelines [4] Pressman’s Principles  An agile yet disciplined framework for building web applications [5]
  7. 7. NIELSEN’S HEURISTICS (EXAMPLES)  Help users recognize, diagnose and recover from errors  Error messages should be expressed in plain language, precisely indicate the problem, and constructively suggest a solution
  8. 8. NIELSEN’S HEURISTICS (EXAMPLES)  User control and freedom  Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue
  9. 9. PRESSMAN’S PRINCIPLES (EXAMPLES)  Navigability  The user should be able to understand how to move about the WebApp without having to search for navigational links
  10. 10. THE USER GROUP & THE USABILITY TESTING Primary school teachers  Paper Interface Testing  Participants completed tasks  Participants gave us feedback about our concept, the design and the ease of usability  After each round of usability testing we received feedback from participants and amended out prototype accordingly  From this process we made significant adjustments, such as changing graphing of behaviour to present data in a clearer way 
  11. 11. USER GROUP Persona Example  Sarah Smith, 28 year old primary school teacher. She is organised and always keeps on top of tasks. Owns many computer gadgets so is computer literate. Motivated by innovation and using a modern and technical approach to learning, she believes it’s the way forward and is excited to learn more about Optimising Children’s Outcomes (OCO) using a monitoring system.
  12. 12. PAPER USABILITY TESTING Test Stage 1 Homescreen  Feedback Change search bar to class list (as nothing under it – too much white space)  Include profile picture of child?   Changes  Convert to List
  13. 13. PAPER USABILITY TESTING Test Stage 2 Homescreen  Feedback   Divide List to allow it to look more obviously like a button Changes Change list layout  Include button arrows 
