2. THE APPLICATION
Apple iPad Application
๏ข Aim of the application is to monitor and manage
classroom behaviour
๏ข Monitors
๏ข
Studentsโ eye-contact with the blackboard
๏ Noise levels of the classroom
๏
Complies data into easy to read graphs
๏ข Allows teachers to examine class performance
throughout the day
๏ข Each child will have a profile
๏ข Data from the App can be emailed to parents
๏ข
3. THE TECHNOLOGY
Axure and Adobe Illustrator
Axure
๏ข A wireframing, rapid prototyping and specification
software tool aimed at web and desktop
applications
๏ข Why we chose Axure
Previous knowledge using the system
๏ Creates detailed, realistic prototypes
๏ Acts out user requests (buttons, type, etc.)
๏
4. Adobe Illustrator
๏ข A vector based graphics editor developed by Adobe
๏ข We will be using Illustrator to create graphics for
our app
๏ข Why we chose Adobe Illustrator
๏
๏
๏
Creates good quality graphics
Strong knowledge with using the system
Less restricting than other programmes, such as
Photoshop
5. THE PSYCHOLOGICAL RESEARCH
Eye-Tracking
๏ข A study examined studentโs attention in class and
gaze and focus patterns
๏ข Results showed studentsโ focused more on the
blackboard than the instructor [1]
Noise Levels
๏ข Studies have shown that high levels of โclassroom
acousticsโ can have an adverse effect on studentsโ
academic performance [2]
๏ข Research illustrates that childrenโs performance at
school including cognitive abilities such as memory
and reading ability as well as motivation can be
negatively affected by noise [3]
6. THE DESIGN PRINCIPLES
(INTERFACE DESIGN)
Nielsenโs Heuristics and Pressmanโs Principles
๏ข How we plan to apply interface design rules to our
prototype
Nielsenโs Heuristics
๏ข They are called "heuristics" because they are more
in the nature of rules of thumb than specific
usability guidelines [4]
Pressmanโs Principles
๏ข An agile yet disciplined framework for building web
applications [5]
8. NIELSENโS HEURISTICS
(EXAMPLES)
๏ข
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
10. THE USER GROUP & THE USABILITY TESTING
Primary school teachers
๏ข Paper Interface Testing
๏ข Participants completed tasks
๏ข Participants gave us feedback about our
concept, the design and the ease of usability
๏ข After each round of usability testing we received
feedback from participants and amended out
prototype accordingly
๏ข From this process we made significant
adjustments, such as changing graphing of
behaviour to present data in a clearer way
๏ข
11. USER GROUP
Persona Example
๏ข 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 itโs the way forward and is excited to learn
more about Optimising Childrenโs Outcomes (OCO)
using a monitoring system.
12. PAPER USABILITY TESTING
Test Stage 1
Homescreen
๏ข Feedback
Change search bar to
class list (as nothing
under it โ too much
white space)
๏ Include profile picture
of child?
๏
๏ข
Changes
๏
Convert to List
13. PAPER USABILITY TESTING
Test Stage 2
Homescreen
๏ข Feedback
๏
๏ข
Divide List to allow it to
look more obviously
like a button
Changes
Change list layout
๏ Include button arrows
๏
