Reusability
Definitions as currently used in literature Industrial vs. craft model
Economic benefits
Meta data
Reuse of components/modules
Reuse in different learning contexts
Object-oriented programming context (code)
“Patterning” – another term
How do we think about reusability from a author’s/developers’s perspective?
Traditionally, reusability has focused upon
the reuse and the integration of the
particular LO in new learning environments.
Consequently, efforts have concentrated
upon metadata and repository efforts.
As educational developers the question is
not how do we reuse or mix and match LOs’
but rather…
Reusability from a author’s/developer’s perspective How can we reuse aspects of the LOs’ to…
Reduce development time Decrease cost, Increase the number of specific content-
related LOs’ while Reuse learners existing knowledge and
mental models with variants of existing LOs’?
Reusability Framework
Code Reuse
Patterning + Templating
Interface Design
Navigation
Graphics/artwork/Look and feel
Pedagogy—educational context
Specific small content components ex: assignment, instructions, technical factual info
Large Content re-purposing—Versioning
User familiarity—prior knowledge
Higher-Order Reuse
Lower-Order Reuse
Existing Learning Object
Conceptual Frameworks Learning Object
Technical Aspects - Conversion Helped design &
develop initial learning object
Brought onto new LO team to help with the rapid development process of building a new learning object from an existing one
Technical Aspects - Conversion

Learning Object Structure
Technical Aspects - Conversion Changes
Navigation Code-cleanup, re-organized file/folder structure Swap text (copy & paste) Swap video (changed links)
Approximate time: less than a day! Benefits for me:
Fastest LO I’ve ever built! Revisit and improve project Leverage existing resources through re-use
New Learning Object
Choosing, Using + Assessing Learning Objects
Study Results
26 students, instructional design course
rated the learning object
3 characteristics examined Easy of Use Technical Challenges Learning
Results – Ease of Use
Rating Item
4.69 The multimedia tutorial was easy to use.
4.62 The navigation within the multimedia tutorial was clear and easy to use.
4.54 I was able to fully use the multimedia tutorial by following the instructions provided.
4.73 The material presented in the multimedia tutorial flowed in a logical order.
Results – Technical
Rating Item
4.69 I was not disadvantaged because I possess adequate computer skills.
4.69 I did not miss important information because the technology worked correctly.
4.73 The hardware/software requirements did not present a problem for me.
3.77 I have not used this multimedia tutorial due to technical difficulties.
Results – Learning
Rating Item
4.31 Helped me learn the materials in a new way.
4.46 Helped me to visualize the concept better.
4.27 Helped me to better understand the concept presented.
3.96 I was able to work through examples in a way that would not have been possible by attending a lecture or reading a textbook.
4.12 I was able to experience situations that I otherwise wouldn't have done in the classroom or studying from a textbook.
Comments - Negative
Links to other LO examples were too
general
– wanted actual LOs
Video clips were too long
– time of clip not presented
Too much text
Series of minor navigation/graphics
preferences
Comments - Positive
Layout/Interface great
Navigation easy
Theme was good
Good information and support materials
Future Phases of Rapid Development
Template phase Use at CLOE PPT template + Flash Template Aids in speeding up process for faculty +
developers who may not know Flash well Modifications to original Still under development
