Digital Media in the Classroom
4th Edition
Chapter 1
Integrating Educational
Technology into the Curriculum
Computer, Information, and
Integration Literacy
Computer literacy
Information literacy
Knowledge and understanding of computers and
their uses
Knowing how to find, analyze, and use information
Integration literacy
The ability to use computers and other
technologies combined with a variety of teaching
and learning strategies
Computer, Information, and
Integration Literacy
Computer technology and digital media are
present in every aspect of daily living — in the
workplace, at home, in the classroom, and for
entertainment
What Is a Computer
and What Does It Do?
An electronic device, operating under
the control of instructions stored in its
memory, that can accept data, process
the data according to specified rules,
produce results, and store the results
for future use
A computer is a computational device
What Is a Computer
and What Does It Do?
Data - collection of unorganized facts
Information - data that is organized
Input - data entered into a computer
Output - processed results from a
computer
What Is a Computer
and What Does It Do?
Storage – holding data and information
for future use
Information processing cycle – the cycle
of input, process, output, and storage
Hardware – the electronic and
mechanical equipment that makes up
the computer
Software – a series of instructions that
tells the hardware how to perform tasks
The Evolution of Computers
and Digital Media
The goal of multimedia computing and
communications is to assist individuals in
organizing and managing vast amounts of
information in various types of media
Digital media – technologies that allow users
to create new forms of interaction,
expression, communication, and
entertainment in a digital format
The Evolution of Computers
and Digital Media
Computing in the Digital Age
Individuals use digital technology to input,
edit, manage, publish, and share all kinds of
information that was previously either
impossible or too expensive for the average
person to create and share
Digital generation - Today’s youth are much
more media-centric than previous
generations
Digital students / digital kids
Digital media allows teachers to use a
combination of technology tools to appeal to
an array of learning styles digitally

The differences between digital native learners and digital immigrant
teachers.
Digital Native Learners
Digital Immigrant Teachers
Prefer receiving information quickly from
multiple multimedia sources.
Prefer slow and controlled release of
information from limited sources.
Prefer parallel processing and multitasking.
Prefer singular processing and single or
limited tasking.
Prefer processing pictures, sounds, and
video before text.
Prefer to provide text before pictures,
sounds, and video.
Prefer random access to hyperlinked
multimedia information.
Prefer to provide information linearly,
logically, and sequentially.
Prefer to interact/network simultaneously
with many others.
Prefer students to work independently rather
than network and interact.
Prefer to learn “just-in-time.”
Prefer to teach “just-in-case” (it’s on the
exam).
Prefer instant gratification and instant
rewards.
Prefer deferred gratification and deferred
rewards.
Prefer learning that is relevant, instantly
useful, and fun.
Prefer to teach to the curriculum guide and
standardized tests.

The ARCS Motivational Model states that
even the best designed instructional strategy
will fail if students are not motivated to learn
