Learning Objects

• a Learning Object is defined as any entity,
  digital or non-digital, that may be used for
  learning, education or training. (LTSC, 2002)
• "Learning Object Any digital resource that can
  be reused to support learning. The term Learning
  Objects generally applies to educational
  materials designed and created in small chunks
  for the purpose of maximizing the number of
  learning situations in which the resource can be
  utilized." (Wiley, 2002)

Learning Object Issues

• Information Objects vs Learning Objects
• Learning Object implies embedded pedagogy
• Reusability
• Granularity vs Context
• Finding Learning Objects - Metadata
• Evaluating
• Instructional Design

5
The Project

• This research project involved developing and
  piloting multimedia Learning Objects during
  2003/2004
• Research Questions
• (1). What are the key factors in designing
  Learning Objects that are reusable for learning
  concepts in Audio Engineering - a discipline that
  traditionally teaches these concepts in a
  face-to-face hands-on mode?
• (2). To what extent can these Learning Objects
  support learner interactivity and interest, and
  thus provide pedagogically rich learning
  environments that engage and motivate the learner?

Interactive Mixer

• Learning Outcomes/Objectives
• At the completion of using the Learning Object,
  students should be able to
• (1). Describe the function of key parameters of
  an audio mixing desk.
• (2). Demonstrate the ability to create an
  appropriate mix for a multi-track drum-kit.
• (3). Critically evaluate an example mix.

Microphone Explorer

• Learning Outcomes/Objectives
• At the completion of using the Learning Object,
  students should be able to
• (1). Choose an appropriate microphone for
  recording a particular instrument.
• (2). Demonstrate appropriate microphone placement
  for recording or live sound.
• (3). Differentiate the sound of different
  microphones.

Equalization

• Learning Outcomes/Objectives
• At the completion of using the Learning Object,
  students should be able to
• (1). Describe the three main parameters of a
  parametric EQ and how they affect the sound file.
• (2). Demonstrate appropriate parametric EQ
  settings for various instruments.
• (3). Evaluate how EQ can enhance the sound of an
  instrument.

  compressor and gate, and how they affect the
  sound file.
• (2). Demonstrate appropriate compression and
  gating settings for various instruments.
• (3). Evaluate how compression and gating can
  enhance the sound of an instrument.

Conclusions/Lessons 1

• Recommendations for interactive multimedia
  Learning Object development are
• Make Instructions and Learning Outcomes clear and
  explicit
• Provide multiple assessment options that
  educators can choose to link to each Learning
  object.
• Provide as high a level of user interactivity as
  possible
• Include participant-oriented evaluation as an
  integral part of the design process

31
Conclusions/Lessons 2

• Emulate real world environments as closely as
  possible
• Choose a multimedia architecture that will suit
  the project requirements
• Allow plenty of time for development evaluation
• Provide training for educators to develop the
  skills to embed the Learning Objects within the
  wider learning environment and thus maximize the
  learning potential of Learning Objects
