2. TASK ANALYSIS
The following is a presentation of how to develop an
instructional content to be delivered through an eLearning
system.
Basic Academic Concept - 2014
3. TASK ANALYSIS
Before we move further, let's define what we mean by instructional
content.
An instructional content is a set of learning
experiences presented through an e-learning
system in such a way that learning is less
stressful and more effective.

4. TASK ANALYSIS
We distinguish instructional content from informational
content. Informational content is a discrete piece of
information represented graphically (text, pictures), aurally
(spoken words, music, sounds), or represented by other
means.
Basic Academic Concept - 2014
5. TASK ANALYSIS
Instructional content is informational content arranged in
certain ways so that learning outcome is maximized.
A technique known as Task Analysis creates instructional
content from informational content.

The following example is a task analysis of the concept
"induction" as found in elementary physics or electricity.

7. TASK ANALYSIS
Instructional Content Development
The first step is to identify the elements of induction. Usually a
definition or a general description of the term is a good start.

Below is a description of the concept “induction”.
When a changing magnetic field cuts across a
conductor, voltage is created across the
conductor.

The next step is to show or give examplars and non-examplars of
induction.

Examplar of induction
The magnet moves inside the coil. The magnetic
field cuts across the coil. The movement of the
magnet changes the magnetic field. The changing
magnetic field creates voltage and makes current
flow in the wire.
The current deflects the pointer in the galvanometer.

Instructional Content Development
Examplar of induction
The magnet moves out of the coil. The magnetic
field cuts across the coil. The movement of the
magnet changes the magnetic field. The changing
magnetic field creates voltage and makes current
flow in the wire in the opposite direction.
The current deflects the pointer in the galvanometer in the other direction.

12. TASK ANALYSIS
Instructional Content Development
Non-examplar of induction
The magnet is inside the coil. The magnet is
not moving. The magnetic field cuts across the
coil, but the magnetic field is not changing.
Therefore, there is no voltage and the current
is not flowing.
The pointer in the galvanometer does not move.

Definition of Induction
The process of creating voltage by a changing magnetic field is
known as induction and the voltage is called an induced voltage.
The induced voltage is also known as an induced electromotive
forced or induced emf.

Summary
There are two conditions to induce voltage. First, the magnetic
field must cut across the conductor. Second, the magnetic field
must be changing.
