Vocabulary mastery is a fundamental aspect of language learning as it
supports students’ ability to understand and use language effectively. However,
many students still experience difficulties due to limited vocabulary knowledge and
the use of less effective teaching strategies in the classroom. This study aims to
investigate the effectiveness of guessing meaning from context in improving
students’ vocabulary mastery. This research employed a quasi-experimental design
involving an experimental group and a control group consisting of 49 eighth-grade
students at SMPN 1 Mepanga. The data were collected through test (pre-test and
post-test) used to measure students’ vocabulary achievement. The results showed
that the experimental group outperformed the control group. The t-test result
revealed that t-count (4.54) was higher than t-table (2.01) at the 0.05 significance
level, indicating that the alternative hypothesis was accepted. Therefore, guessing
meaning from context is an effective strategy for improving students’ vocabulary
mastery.
