This research investigates the effectiveness of using the story mapping technique to
improve the speaking skills of tenth grade students at SMA Negeri 1 Sindue. The
study was conducted because many students faced challenges in speaking English,
such as limited vocabulary, pronunciation difficulties, low confidence, and fear of
making mistakes. A quantitative approach with a quasi-experimental pre-test and
post-test control group design was employed. The sample consisted of two classes:
the experimental group (n = 34), which was taught using story mapping, and the
control group (n = 36), which received oral presentation method method, where
students practiced speaking by presenting material orally in front of class. Students’
speaking skills were assessed through fluency and comprehensibility by two trained
raters specializing in speaking with, maintained scoring reliability. The results of
the descriptive statistics showed that the experimental group achieved a notable
improvement, with the mean score increasing from 42.06 in the pre-test to 52.35 in
the post-test, while control group did not show meaningful changes. The MannWhitney U Test further confirmed a significant difference between both groups,
indicated by an Asymp. Sig. value of 0.004, supported by a medium effect size (r =
0.34). these findings demonstrate that story mapping helps students organize ideas
more effectively, speak more fluently, and express thoughts more clearly. Therefore,
story mapping is considered an effective technique for enhancing speaking skills
and is recommended for use in English speaking classroom
