Abstract

This research and development study aimed to develop and evaluate speaking learning materials integrating video blogging (vlogging) within a Project‑Based Learning (PBL) framework for eighth‐grade students at SMP Swasta IT Ad Durrah, Medan. The ADDIE model (Analysis, Design, Development, Implementation, Evaluation) guided the systematic design of a vlog‑based speaking module targeting fluency, pronunciation, vocabulary, accuracy, and organization in oral presentations. Needs analysis through classroom observation, teacher interviews, and student questionnaires revealed that speaking instruction was dominated by textbook‑based drills, limited authentic practice, and low learner confidence, despite high student interest in technology‑mediated activities. Product development produced a multi‑unit module including model vlogs, guided speaking tasks, scaffolded project stages, and performance rubrics aligned with the junior high school curriculum. Expert validation data indicated that the materials met criteria of content validity, language clarity, presentation quality, and media feasibility, with an overall mean score of 4.65 categorized as “very feasible.” Implementation with 60 students showed substantial gains in speaking performance: the mean score increased from 66.8 (pre‑test) to 82.9 (post‑test), with a mean gain of 16.1 and a paired‑sample t‑observed value of 12.45 exceeding t‑table 2.04 at the 0.05 significance level. Qualitative findings further indicated increased motivation, confidence, and engagement. These results suggest that vlog‑based, PBL‑oriented materials are valid, practical, and effective for enhancing lower secondary EFL learners’ speaking skills.

Abstract

The low mastery of English vocabulary among junior high school students remains a significant challenge in achieving the learning objectives of the Independent Curriculum. This research aimed to develop and evaluate the effectiveness of game-based learning materials for 8th-grade students at SMP Methodist Pantai Labu. The study followed the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model of Research and Development (R&D). Data were collected through expert validation, observations, and a one-group pre-test–post-test design involving 32 students. The findings indicated that the developed materials were highly valid and feasible based on expert judgment. Statistical analysis through the Paired Sample T-Test revealed a significant improvement in students' vocabulary mastery, with the mean score increasing from 57.09 to 83.53 (p = 0.000). The intervention achieved a Large Effect Size (Cohen’s (d = 2.11) and a Moderate N-Gain score (0.63), demonstrating high learning efficiency. Furthermore, the classical mastery rate increased dramatically from 0% to 90.6%, proving that the product effectively narrowed the achievement gap and supported differentiated learning. The integration of gamification elements successfully created a student-centred environment that reduced learning anxiety. It is concluded that game-based learning materials are a robust and effective solution for enhancing English vocabulary acquisition in the modern Indonesian classroom context
