Abstract
The purpose of this study was to test the principle of
modality on student's ability to learn concepts, rules and procedures
by using audio to deliver verbal information when that information is
designed to support non-verbal information such as animations in a
computer-based lesson. This was done by comparing the effect of two
types of audio support mechanisms- a simple support mechanism
consisting of declarative statements explaining the animated sequence
and a complex support mechanism consisting of questions and answers
explaining the animated sequence- on undergraduate student
achievement of conceptual, rule and procedure knowledge. A control
group consisting of the same computer-based lesson without any
auditory support of the animation was also employed. Learning was
measured through drawing, terminology, and comprehension tests.
Description
With computers coming equipped with multi-media
features such as the ability to play sound and animation, teachers
and instructional designers are able to develop and deliver lessons
in novel ways using both the visual and auditory channels of
students. But, is student performance improved by the use of both
channels as opposed to the traditional delivery method relying solely
on the visual channel? And, at what learning level (the factual,
conceptual, rule & procedure level) is there improvement in
performance when both channels are used?
According to cognitive load theory (Kalyuga, Chandler and Sweller
1988, 1989; Sweller 1988; Baddeley 1986, 1992) methods of instruction
reducing working memory load in order facilitate the encoding and
storing of the information in long-term memory are effective. One
such method is dual coding theory (Sadoski and Paivio 2001; Clark and
Paivio 1991; Paivio 1971, 1986, 1990). Dual coding theory assumes we
have two information processing systems: a verbal system, comprised
of words, whose strength lies in its sequentially ordered hierarchy,
each bit of information paves the way for the next, and a non-verbal
system whose strength lies in its synchronous (holistic) hierarchy.
Using audio to deliver verbal information when that information is
designed to support non-verbal information such as graphics,
pictures, and animations can enhance the effect of using both the
verbal and visual systems. This is known as the modality effect
(Clark & Mayer 2003; Penney 1989; Paivio 1986). The modality effect
(Clark & Mayer, 2003, pp. 93) states "people learn more deeply from
multimedia lessons when words explaining concurrent animations or
graphics are presented as speech rather than as onscreen text." The studies reviewed indicate that the modality effect works well at
improving student's verbal recall of factual information (Mayer 1991,
Mayer 1992, Barron 1993, Mousavi 1995, Mann 1995, Mayer 1996, Mayer
1998, Moreno 1999, Mayer 2001, and Moreno 2002). There is also
indication that the modality effect works at improving student's
ability to solve problems (Mayer 1991, Mayer 1992, Barron 1993, Mayer
1994, Mousavi 1995, Mayer 1996, Mayer 1998, Moreno 1999, Chuang 1999,
Mayer 2001, Moreno 2002). However, there is limited information
regarding the effect of modality of student achievement of learning
concepts, rules and procedures. The studies conducted by Mayer (1998)
and Moreno (1999, 2002) found evidence to support the positive effect
of modality on student's ability to learn conceptual information but
these learning levels were not isolated and studied on their own. In
these studies, student's ability to recall facts, identify concepts,
and solve problems were tested together. This leaves open the
question of how effective is the use of modality if the goal of the
lesson is to facilitate achievement of conceptual and rule/procedure
knowledge? This study seeks to begin filling in the gap in the
literature by isolating these two intellectual skill learning-levels.
