The Use of Contextual Clues Strategy to Improve Students’ Vocabulary Mastery at SMP Negeri 15 Palu

Abstract

The research used a quasi-experimental approach with 150 students as the population. The first 30 students were chosen for experimental group, and another 30 for the control group through purposive sampling. In order to gather the data, both groups completed a multiple-choice test as a pre-test and a post-test. The results from the ore-test showed that the control group had slightly higher average score (63) compared to the experimental group (58). However, after implementing the Contextual Clues Strategy, the post-test scores revealed significant improvement in the experimental group, which achieved an average score of 83, compared to the control groups' 69. Furthermore, the statistical analysis showed that the t-count value (3.14) was greater than the t-table value (2.002) at a 0.05 significance level. These findings clearly suggest that using the Contextual Clues Strategy can significantly enhance students' vocabulary mastery.
