The Effectiveness of Digital Mind Mapping Using GitMind Application to Teach Writing Descriptive Text

Abstract

This research is conducted to determine the effectiveness of digital mind mapping using GitMind application to teach writing descriptive text. A pre-experimental research design with a one-group pretest-posttest design was used in this study. The study sample consisted of 36 students enrolled in Class XE that was obtained through cluster random sampling. Pre-test and post-test instruments were administered, revealing an increase in the students’ mean score from 69.56 to 78.42. The paired sample t-test resulted in a t-statistic of 6.396, which was higher than the t-critical (2.03). This result demonstrated a statistically significant difference observed between pre-test and post-test scores. Moreover, the findings confirmed the alternative hypothesis (H_a) and refuted the null hypothesis (H₀), based on a p-value of 2.33E-07, which was significantly lower than the established significance level (0.05). The results supported that digital mind mapping using GitMind effectively facilitated the teaching of descriptive text writing. Furthermore, the results showed that the effect size of the treatment was 1.066, categorized as a “strong effect”. Based on these findings, it is recommended to utilize GitMind, a digital mind mapping tool, for teaching writing descriptive text.
