Abstract

General Background: Writing is a core English skill that requires mastery of vocabulary and grammar, yet students often struggle in both areas. Specific Background: At SMPN 2 Limbangan Garut, many eighth-grade students fail to meet writing performance standards due to limited vocabulary and grammar proficiency. Knowledge Gap: Despite the proliferation of AI tools in education, little is known about their effectiveness at the junior high school level in Indonesia, particularly in writing skills development. Aims: This study aims to evaluate the effectiveness of AzVocab.AI, an AI-powered vocabulary learning platform, in improving students’ writing outcomes through enhanced vocabulary and grammar acquisition. Results: Using a true experimental design with three learning cycles (pretest-treatment-posttest), the study found a consistent improvement in scores: vocabulary increased from 41.25 to 75.5 and grammar from 46.25 to 75.5. N-Gain scores were moderate, while regression analysis showed AzVocab.AI accounted for 77.9% of the vocabulary gains and 47.5% for grammar. Novelty: The study presents one of the first empirical validations of an AI-based tool’s impact on junior high school writing performance in Indonesia. Implications: These findings suggest integrating AzVocab.AI into English curricula could significantly enhance student autonomy and language skill development in secondary education settings.Highlight : AzVocab.AI significantly improved students’ vocabulary and grammar scores with a moderate N-Gain category. The platform supports self-directed learning by offering real-time feedback and contextual vocabulary exercises. Regression analysis showed AzVocab.AI contributed 77.9% to vocabulary improvement and 47.5% to grammar enhancement. Keywords : AzVocab.AI, Vocabulary, Grammar, Writing Skill, Educational Technology

Abstract

The mastery of digital technology has become an essential skill for teachers in addressing the demands of 21st-century learning. However, many educators still face limitations in effectively utilizing technology in the learning process. This Community Service Program (PkM) was conducted to enhance teacher competencies through digital-based learning training at PGRI Kabupaten Ciamis. The method consisted of need analysis, module development, hands-on training sessions, and intensive mentoring. The results showed significant improvements in teachers' abilities to utilize digital platforms for planning, implementing, and evaluating learning activities. This program had a positive impact by improving teachers’ digital literacy and enabling the integration of technology into classroom practices. The initiative is expected to foster innovative, adaptive, and relevant learning in the digital era.
