| Summary: | The aim of this study is to investigate the effectiveness of annotations in
nlultimedia on-screen texts using two presentational modes in enhancing
learners comprehension level as well as vocabulary level. The subjects
involved are 44 first year Biotechnology students of USIM. The methodology
employed is experimental comparison of the performance of two groups of
subjects under two different conditions: one using multimedia on-screen text
with the annotations of 'text+animation' and the other using multimedia onscreen
text with the annotations of 'voice+animation'. The instruments used
in this study are the multimedia texts on "transgenesis method' which focuses
on the processes involved in the "Protoplast Fusion' as well as the "Agro
bacterium mediated transfusion' and a Comprehension Test that assessed the
subjects understanding of the reading texts assigned. The neth hod of data
analysis used is of descriptive statistics which uses the frequency count of the
average (mean) value scores as well as the highest (max) and lowest score
(min) in identifying the effectiveness of the multimedia annotations in
facilitating the students comprehension level using the two presentational
modes. Generally, the overall scores indicate that there is no significance
difference in the use of annotations via the two presentational mode -
'text+animation7 and 'voice+animation' as the difference that exist in the
scores are small. However, the findings do indicate that the subjects are found
to emphasise on the use of their visual sense of modality in facilitating their
reading tasks. Subsequently, this has resulted the students that are exposed to
the presentational mode of 'text+animation' to do fairly better than the latter
group 'voice+animation'. Finally, it is important to highlight here that the
annotations (animations) found in the multimedia on-screen text, do to a
certain extent, facilitate the students in understanding a science based text due
to its ability to build referential connections between the two mental
representations in short term memory hence, resulting in better performance
in the tasks assigned |
