The Effect of Metalanguage Technique on the Grammatical Competence of Grade 8 Students in Hadiyyah International Schoolh International School: Basis for Module Writing

Abstract

Grammar is a fundamental aspect of language, yet many students struggle to develop adequate grammatical competence. This study examined the effect of the Metalanguage Technique (MLT) on the grammatical competence of Grade 8 students at Hadiyyah International School International School, employing an embedded mixed-method design. Sixty participants were divided into control and experimental groups. Single Group Pre- and Post-test research design, alongside interviews, were used to gather data. Findings revealed a significant improvement in the experimental group's performance after exposure to MLT, with an 18.6 margin difference which refers to the t-value compared to the control group, which showed no notable gains. Students reported that MLT made grammar lessons engaging, promoted reflection, and encouraged self-correction. The study concludes that MLT is an effective method for improving grammatical competence compared with traditional approaches. A proposed module based on the 5Es framework illustrates how MLT can enhance grammar instruction.
