Abstract

In recent years, mobile-based game language learning has proliferated due to its promising prospects and positive impacts in improving teaching and learning outcomes in English vocabulary development. With this phenomenon, Square Talks® was developed specifically to aid EFL beginner learners with their English vocabulary. This study aims to examine the effectiveness of the game app in developing the learners’ English vocabulary development. This study employed a quantitative approach focusing on 34 EFL beginner learners. The focus has been on how effective the game app was statistically and overall experience of using the game app. Data were collected through vocabulary tests and a survey. The test results showed that Square Talks® has improved the subjects’ English vocabulary development with the t-value of the test results is -19.93 indicating a significant effect in increasing the subjects’ English vocabulary development. The survey result revealed positive acceptance toward playing Square Talks® in terms of effectiveness (4.49), usability (4.34), and satisfaction (4.52). Therefore, Square Talks® can be considered to be an alternative learning tool to facilitate EFL beginner learners’ vocabulary development.

Abstract

Kegiatan Pengabdian kepada Masyarakat (Abdimas) ini bertujuan untuk meningkatkan literasi keuangan digital bagi mahasiswa penyandang disabilitas serta memberikan pemahaman mengenai perlindungan dari pinjaman online ilegal. Berkolaborasi  dengan Otoritas Jasa Keuangan (OJK) Jawa Barat, kegiatan ini memberikan informasi yang relevan dan meningkatkan kesadaran peserta terhadap risiko finansial yang dapat mereka hadapi di era digital ini. Metode pelaksanaan kegiatan dilakukan melalui workshop yang mencakup tiga sesi utama, yaitu pemaparan materi oleh narasumber dari OJK, sesi tanya jawab dan kuis interaktif, serta sesi pengecekan Sistem Layanan Informasi Keuangan (SLIK) OJK secara langsung. Hasil evaluasi dari peserta menunjukkan bahwa mayoritas merasa materi yang disampaikan sesuai dengan kebutuhan mereka, jelas, serta mudah dipahami. Selain itu, aspek pelayanan panitia dan aksesibilitas dalam kegiatan ini juga mendapatkan respons positif, meskipun masih terdapat beberapa aspek yang perlu ditingkatkan, seperti profesionalisme Juru Bahasa Isyarat (JBI), pengaturan tata letak ruangan yang lebih ergonomis, serta penyediaan waktu yang lebih fleksibel untuk pengisian quiz maupun kuesioner. Dengan adanya kegiatan ini, diharapkan mahasiswa penyandang disabilitas dapat memiliki pemahaman yang lebih baik mengenai literasi keuangan digital dan mampu mengambil keputusan finansial yang lebih bijak. Evaluasi dan masukan dari peserta akan menjadi dasar perbaikan untuk kegiatan serupa di masa depan agar semakin inklusif khususnya dalam ruang akademis.

Abstract

This study investigates the speaking anxiety levels of EFL students enrolled in English medium classes (EMI) in a private university. Factors causing students’ speaking anxiety and potential strategies to reduce the speaking anxiety were also examined. Eighty-nine EMI students from ten undergraduate study programs were the respondents of this study. Data were collected by using Horwitz et al.’s (1986) anxiety survey. Findings showed that EMI students exhibited low-level English-speaking anxiety. The cross-tabulation data demonstrated that students perceived comprehension apprehension as the paramount anxiety factor. To reduce their comprehension apprehension, students prefer their lecturers not to over-react their speaking mistakes and degrade them when they make speaking mistakes. These imply that these findings can be used as consideration for preparatory programs for students and lecturers in EMI classes.

Abstract

Purpose The primary objective of this study is to investigate how social media and online games influence student-lecturer interpersonal communication within a campus environment. Additionally, the research aims to identify strategies to mitigate adverse outcomes, such as potential addiction, while leveraging the positive benefits of these platforms to foster stronger academic relationships and English proficiency. Method This research employed a qualitative approach involving 70 Communication Science students in South Jakarta. Data were collected using a combination of semi-structured interviews and 20-item demographic questionnaires. The gathered data were then descriptively analyzed to understand the students' usage patterns and the subsequent impact on their academic communication and social interactions. Results/findings The study found that online games significantly enhance English speaking, pronunciation, and listening-based vocabulary through immersive, interactive environments. Furthermore, social media was shown to improve interaction with peers and lecturers by facilitating collaborative learning and direct engagement, effectively boosting students' confidence in English interpersonal communication. Conclusion These findings highlight the dual nature of digital tools, emphasizing their potential as educational aids despite the challenges of overuse. It is recommended that educators and policymakers develop balanced strategies and informed policies that maximize these linguistic and social benefits while mitigating potential drawbacks to ensure a healthy academic environment.

Abstract

This study presents the development of a speech training application for children with Down Syndrome, utilizing various machine learning algorithms to evaluate pronunciation accuracy. The study compares four widely used algorithms: K Nearest Neighbors (KNN), Naive Bayes, Support Vector Machine (SVM), and Random Forest, in classifying speech accuracy based on Mel Frequency Cepstral Coefficients (MFCC) features. Additionally, the impact of balancing the dataset using Synthetic Minority Oversampling Technique (SMOTE) is evaluated through 5 fold cross validation. The experimental results demonstrate that Random Forest achieves the highest performance with an overall accuracy of 85.35%, precision of 85.39%, recall of 41.79%, F1 score of 56.19%, and a cross validation accuracy of 85.01%, proving its capability to handle complex speech data. In comparison, KNN attains a cross validation accuracy of 80.54%, balancing precision and recall. Naive Bayes yields an overall accuracy of 80.09% (77.83% in cross validation) and a precision of 78.63%, constrained by its feature independence assumption. Meanwhile, SVM achieves a 77.58% cross validation accuracy but records a recall of 0.00% on the baseline dataset, indicating a failure to detect the minority class of poor pronunciation. The application of SMOTE effectively mitigates class imbalance and enhances recall across all models, particularly for KNN and Naive Bayes. Feature importance analysis confirms that lower order MFCC coefficients contribute significantly to classification accuracy. These quantitative findings underscore the viability of implementing Random Forest into speech therapy systems to deliver objective, robust, and accessible pronunciation assessments for children with Down Syndrome.
