    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

    examine the participants acquisition of vocabulary breadth. This study therefore,

    addresses the following research questions (RQ). To answer each research question,

    null hypotheses are derived.

    RQ1: Will there be any significant difference in the pretest and immediate

    posttest reading comprehension scores of the participants?

    reading comprehension scores of participants who are in the control group.

    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.

    Conceptual Framework

    Based on the theoretical foundations discussed above, the conceptual framework is

    built. Figure 2.2 shows the conceptual framework which will be used to answer the

    research questions in this research. This conceptual framework provides the structure

    of the research by specifying the relationship between the research variables, besides

    identifying the boundaries of the research.

    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

    19

  • 7/28/2019 en razi

    20/20

    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.
