THE EFFECTIVENESS OF E-PORTFOLIO ON STUDENTS' WRITING SKILLS AT SMA NEGERI 21 GOWA

Abstract

This study aims to analyze the effectiveness of using e-portfolio, especially Google
Sites, in improving students writing skills, focusing on two main aspects: grammar
and organization. This research was conducted at SMA Negeri 21 Gowa using a
quantitative approach with a pre-experiment design. A total of 35 students from
class XI MIPA 1 were selected as research samples through purposive sampling,
considering their relevance and availability for the study. To collect data, students
were given writing tests before (pre-test) and after (post-test) the application of e-
portfolio. The test was designed to evaluate their writing performance in terms of
grammatical accuracy and organization. The students developed and uploaded
their writing assignments through Google Sites, which allowed for continuous
feedback and revision throughout the learning process. The data collected was
then analyzed using Paired Sample T-Test in SPSS to determine if there was a
statistically significant difference in students writing performance before and after
the treatment. The findings showed significant improvement in both aspects of
writing. The average grammar score increased from 47.14 to 80.71, reflecting an
increase of 71.21%, while the organization score increased from 49.28 to 82.14, or
an increase of 71.11%. Statistical analysis showed a significance value of 0.000 (p
< 0.05), which confirmed the effectiveness of the e-portfolio. These results suggest
that integrating digital tools such as Google Sites into writing instruction can foster
better learning outcomes, increase student engagement, and encourage greater
autonomy in the writing process.
