Purpose and Objective of Study
In view of the existing gap in multimedia annotations studies, the purpose of this
study is to broaden our understanding of the application of different types of
multimedia annotations in facilitating L2 reading comprehension and incidental
vocabulary acquisition. As such, the following research objectives are drawn.
1. To investigate the effects of different multimedia annotations on the reading
comprehension of ESL students.
2. To investigate the effects of different multimedia annotations on the incidental
vocabulary acquisition of ESL students.
Research Questions and Hypotheses
Specifically, the researcher will examine the use of multimedia annotation in a single
mode (audio only) single annotation format (sound only), dual mode (audio-visual)
dual annotation format (sound and text; sound and pictures), and dual mode (audio-
visual) multiple annotation format (sound, text and pictures). The sound-only format,
and sound plus text format require a single coding system (verbal). The sound and
pictures format, and the sound, text and pictures format require dual-coding (verbal
and visual). As for incidental vocabulary learning, specifically, this study will

Definition of Terms
The important terms used in this study are defined conceptually and operationally.
Clearly defined key terms will guide the researcher in data collection, data analysis
and in reporting the findings.
Multimedia annotations
Multimedia refers to the presentation of materials using both words and pictures via
a computer (Mayer, 2001). Greenlaw and Hepp (1999) define multimedia as
information in the form of graphics, audio, video or movies, and a multimedia
document contains a media element other than plain text (p. 44). In multimedia
annotation, words are linked to pictures, audio, videos by annotating them through a
multimedia programme. When the learners encounter a difficult word while reading
via the computer, and if the word is provided with a multimedia annotation, the
learners can click on the word and access a provided annotation. In this study, the
multimedia annotation follows the definition discussed above. Moreover, the word
annotations and glosses are used interchangeably.
Annotation format, annotation mode and coding system
In multimedia annotations, the terms annotation format, annotation mode and coding
system are often used to mean different things. Annotation format refers to the
manner through which the information is presented, which can be in the forms of
12
-
7/28/2019 en razi
13/20
texts, pictures, sound recordings or videos. If an annotation presents the information
through the use of written text only, sound only, picture only, or video only, then a
single annotation format is used. If an annotation combines any two of the above
forms, then a dual annotation format is used. A multiple annotation format combines
more than two forms of annotations.
Multimedia annotation also employs the use of different presentation modes such as
auditory (sounds, spoken texts) and visual (printed texts, graphics, videos). Single
mode presentation engages either only the auditory mode or only the visual mode.
Dual mode annotations combine both the auditory mode and the visual mode.
The use of multimedia annotations is drawn upon the assumptions of the dual-coding
theory (Paivio, 1990; Sadoski & Paivio, 2001) which claims that the human mental
process derives perceptions from various sensory modalities. Accordingly,
multimedia annotations are presented through two different coding systems verbal
and visual. Printed and spoken texts are processed by the verbal system whereas
pictures and illustrations are processed by the visual system. In the present study,
the terms annotation format, annotation mode and coding system take on the above
definitions.

Theoretical Basis of the Study
This study investigates the effects of multimedia annotation on the reading
comprehension and vocabulary acquisition of ESL learners. This study is carried out
based on the schema theory of reading which explains the acquisition of knowledge
and the interpretation of text by the readers while utilizing their built-in schemata.
The interactive model of reading which views reading as a cognitive process
involving the simultaneous interaction of information obtained through bottom-up
decoding and top-down analysis, and the constructivist theory of learning which
recognizes the learners active role in collaboratively creating knowledge through
social negotiations from multiple perspectives also provide the theoretical bases for
this study. Since this study focuses on the use of multimedia annotation in ESL
reading comprehension and vocabulary learning, the cognitive theory of multimedia
learning (Mayer, 1997, 2001) is also used as its theoretical framework. The
theoretical framework is presented in Figure 2.1.

CHAPTER III
RESEARCH METHOD
Introduction
The objective of this study was to examine the effects of multimedia annotations on
the reading comprehension and incidental vocabulary acquisition of ESL students.
The research design employed in this study was a true-experimental design. This
design was used because the subjects were randomly assigned to the different
treatment groups.
Research Design
Specifically, this research study employed the pretest posttest control group design.
The design notation for this study is shown in Figure 3.1.

Data Analysis
The data in this study was analyzed quantitatively. Descriptive statistics for the
reading comprehension and vocabulary tests were carried out. Since this was an
experimental study, and the total subjects were more than 15, parametric tests were
used. Statistical significance was accepted at the .05 level of confidence.
In this study, the researcher had hypothesized that group means did not differ for the
two dependent variables, which were reading comprehension and incidental

vocabulary acquisition. As such, the statistical tests used to test all the null
hypotheses was the multivariate analysis of variance (MANOVA). MANOVA was
preferred over the analysis of variance test (ANOVA) because MANOVA bypassed
the assumption of compound symmetry and sphericity. The MANOVA could also be
used to uncover the main and interaction effects of categorical independent variables
(called factors) on an interval dependent variable. A main effect is the direct effect
of an independent variable on the dependent variable. An interaction effect is the
joint effect of two or more independent variables on the dependent variable. Whereas
regression models cannot handle interaction unless explicit crossproduct interaction
terms are added, MANOVA uncovers interaction effects on a built-in basis. In
interpreting the results of MANOVA, one can conclude that the respective effects are
significant if the overall multivariate test is significant.
After obtaining a significant multivariate test for a particular main effect or
interaction, a multivariate F value (Wilks lambda) based on a comparison of the
error variance/covariance matrix and the effect variance/covariance matrix could be
obtained. The covariance was included because the two measures were probably
correlated and this correlation must be taken into account when the significance test
was performed.
