Abstract

This study investigates the effectiveness of the Mind Mapping technique in improving junior high school students’ ability to organize ideas when writing descriptive texts at one of the public Islamic schools in West Lombok. A quasi-experimental design was used, consisting of two groups of seventh-grade students: an experimental group that received instruction through Mind Mapping and a control group that was taught using conventional methods. Before the treatment, students’ initial writing ability was relatively low, as indicated by the pre-test mean score of 60.25, showing limited skills in organizing ideas clearly and coherently. Mind Mapping, defined in this study as a visual technique that helps students generate, connect, and structure ideas through branching diagrams starting from a central concept, was applied over three instructional sessions using the Right Column Mind Map. Data were obtained from pre-test and post-test activities involving writing tasks describing a person and analyzed using an independent samples t-test in SPSS 31, including normality and homogeneity tests, to determine the significance of differences between the two groups. The findings indicated that the experimental group experienced a notable improvement, with their mean score increasing from 60.25 on the pre-test to 79.42 on the post-test—an overall gain of 19.17 points. Meanwhile, the control group’s improvement was limited to 10.41 points. The independent samples t-test showed that this difference was statistically significant (p = .001 < .05). A further analysis revealed that Mind Mapping improved three aspects of idea organization: unity (maintaining focus on the central idea), completeness (expanding relevant supporting details), and coherence (ensuring logical sequencing and smooth transitions between ideas). Thus, the null hypothesis (H?), which stated that Mind Mapping does not significantly enhance students’ ability to organize ideas, was rejected. In contrast, the alternative hypothesis (H?) was accepted. These findings imply that teachers can adopt Mind Mapping as an effective pre-writing strategy to help students plan and organize ideas more systematically, thereby supporting the objectives of the Merdeka Curriculum in fostering creativity, critical thinking, and structured writing.

Abstract

This study aims to investigate the effect of the Word Detective technique on improving the vocabulary skills of eighth-grade students at MTs. Putri At-Tahzib. The background of the study is based on initial observations showing that most students have low vocabulary skills and are less actively involved in English learning. This study used a quasi-experimental design with two groups: a control group taught conventionally and an experimental group taught using the Word Detective technique. The research sample consisted of 55 students selected through a total sampling technique. Data collection was carried out through a pre-test and post-test with an instrument in the form of 20 multiple-choice questions that have been validated and have a high level of reliability (Cronbach's Alpha = 0.798). The results of the analysis showed that the experimental group experienced an increase in average scores from 52.86 in the pre-test to 74.46 in the post-test, while the control group increased from 51.30 to 63.33. The independent samples t-test yielded a calculated t-value (5.297) greater than the t-table (2.006) at a significance level of 0.05, meaning the alternative hypothesis (Hₐ) was accepted and the null hypothesis (H₀) was rejected. This finding proves that the Word Detective technique has a significant influence in improving students' vocabulary skills. The implications of this study indicate that the Word Detective technique can be an effective learning strategy to improve students' vocabulary skills through an active approach that utilizes contextual clues and word structures. This technique is recommended for application in English learning because it encourages active and meaningful student involvement in the vocabulary acquisition process.
