comes usability issues and converts
text-based scenarios to multimedia
scenarios. The text-based case studies
make the visualization of class environments
more challenging and clearly
lack features, such as user interactivity
and good usability.
In this environment, the user
may control the flow of the application.
Users interact with the application and
share their opinions on the case study.
This structure provides reflection questions
for each case study, which allows
preservice teachers to work through
their ideas in a thoughtful manner. This
gives them an opportunity to prepare
for various classroom scenarios they
may encounter when teaching.
The Spectrum Educational Tool
Software Modeling and Software
Life Cycle
This project employed evolutionary
prototyping (EP), which is a process
that differs from throwaway prototyping/programming,
where you build
a prototype and possibly abandon it.
Using EP, the design team plans to iteratively
refine and improve the application
until it meets a satisfactory level
of performance as requested by the client
(Crinnon 1991; Davis 1992). Our
main goal was to build a robust and
flexible prototype in a structured manner
and constantly refine it based upon
feedback. (See Figure 2.) This process
allows a continuous refinement of the
system and developers to tweak parts of
the application that they better understand
without needing to worry about
those they understand less. The Spectrum
educational tool is an application
developed based on the improvements
in the existing application and new requirements
from the user. We made the
new application more interactive and
helpful to teachers by providing them
control over the content.
