Lecture 6 Multimedia and Contiguity

• EDIT 235
• Prof. Pembrook

2
Objectives

• After completing this lecture you will be able
  to
• Discuss and apply the multimedia and contiguity
  principles
• Describe to practical applications of the
  multimedia and contiguity principles
• Use Captivate to record a software demo

Whats wrong with this elearning frame?

• The Otto cycle is characterized by four strokes,
  or straight movements alternately, back and
  forth, of a piston inside a cylinder
• intake (induction) stroke
• compression stroke
• power (combustion) stroke
• exhaust stroke
• The cycle begins at top dead center, when the
  piston is at its uppermost point. On the first
  downward stroke (intake) of the piston, a mixture
  of fuel and air is drawn into the cylinder
  through the intake (inlet) port. The intake
  (inlet) valve (or valves) then close(s), and the
  following upward stroke (compression) compresses
  the fuel-air mixture.
• Four-stroke cycle (or Otto cycle) The air-fuel
  mixture is then ignited, usually by a spark plug
  for a gasoline or Otto cycle engine, or by the
  heat and pressure of compression for a Diesel
  cycle of compression ignition engine, at
  approximately the top of the compression stroke.
  The resulting expansion of burning gases then
  forces the piston downward for the third stroke
  (power), and the fourth and final upward stroke
  (exhaust) evacuates the spent exhaust gases from
  the cylinder past the then-open exhaust valve or
  valves, through the exhaust port.

Do you see the elephant?

• People learn best using a combination of what two
  media elements?
• Words and pictures!

5
Multimedia Principle

• Use words with graphics rather than words alone.
• Why?
• Schema includes verbal visual info

6
Is this better?
The cycle begins at top dead
center, when the piston is at its uppermost
point. On the first downward stroke (intake) of
the piston, a mixture of fuel and air is drawn
into the cylinder through the intake (inlet)
port. The intake (inlet) valve (or valves) then
close(s), and the following upward stroke
(compression) compresses the fuel-air mixture.

Contiguity Principle

• Place corresponding words and graphics near one
  another.
• Why?

8
How about this?
The cycle begins at top dead center, when the
piston at its uppermost point.
The intake (inlet) valve then closes, and the
following upward stroke (compression) compresses
the fuel-air mixture.

Summary Multimedia Contiguity

• Use words with graphics rather than words alone.
• Place corresponding words and graphics near one
  another.

11
Guidelines

• Place explanatory text adjacent to graphic it
  describes.
• Put feedback on the same screen as the question
  or interaction it supports.
• Put procedures and facts on the same page as the
  content it supports or that must be referenced,
  or
• Use pop-up text or windows
• Example

Activity 6-1 Record Software Demo

• Use procedures from Activity 5-2
• Participate in class demo of Captivate

14
Assignment 6-1- Record a Captivate Demo

• Record a captivate demonstration that shows a
  learner how to
• Insert a new slide in PowerPoint
• Insert text on the slide
• Try to add as much interactivity and user control
  as possible, and
• Pay attention to Contiguity!
