Fostering communicative competence: a task-based approach to public speaking materials development
Get PDFWhile ample studies have explored the creation of task-based materials to enhance the English proficiency of university students, there has been limited research on how such materials can be tailored to promote university students' public speaking competence. This paper presents findings from a research and development (R&D) study aimed at refining English teaching materials using a task-based approach to bolster university students' public speaking abilities. The study was conducted in the English Language Department at a public university in Medan and followed the R&D model by employing a multi-phase methodology. Initially, a needs analysis was carried out using a questionnaire to gather student data, focusing on their learning needs and preferences for public speaking skill development. The data were analysed using descriptive statistics to identify key trends. Based on the findings, task-based public speaking materials were developed, featuring structured debates, role-plays, and presentations that encouraged students to engage in real-world speaking tasks. These materials aimed to cultivate both linguistic and strategic competencies necessary for effective public speaking in academic and professional contexts. The materials were then validated through expert evaluation to ensure content accuracy, alignment with public speaking objectives, and pedagogical relevance. Following validation, the materials were piloted in the classroom, and qualitative feedback was collected from both the lecturer and students through interviews and surveys. The validation process confirmed the practicality and effectiveness of the task-based materials. Additionally, both the lecturer and students reported positive outcomes, noting significant improvements in the students' public speaking competence and increased engagement due to the real-world relevance of the tasks

Understanding raciolinguistic dynamic in EFL classroom: a systematic literature review on language and identity in global educational contexts
Get PDFThis research aims to explore and analyze the raciolinguistic dynamics that influence teaching and learning experiences, as well as educational access, within global EFL contexts. Through an in-depth review of current literature, this research explores how language biases and hierarchies influence educational structures, create inequalities and affect social mobility. The study not only highlights the issues of raciolinguistic but also expands critical understanding of the role of language in reproducing or undermining social injustice. The research shows how raciolinguistic ideas have been globalized and adapted to a variety of circumstances by utilizing bibliometric analysis of the Scopus database and applying it to a wide range of previously published works. It also highlights the need for educational practices that bring these ideas into play to solve racial and linguistic disparities. The results show that racialolinguistic ideas are not only globally spread, but also adapted in various educational contexts, reflecting how language policies and pedagogical practices can reinforce or challenge social injustice. Using a cross-country survey and case studies, this study identifies adaptive strategies used in EFL teaching to deal with linguistic and racial challenges. In addition, the findings emphasize the importance of policy-based approaches and more inclusive pedagogies to reduce language and racial disparities in education. By cross-national surveys and case studies, the study emphasizes the significance of adaptive techniques and the complex interactions between language and race in EFL classroom

The Effect Of Human Development Index, Minimum Wage, And Open Unemployment Rate On Poverty In East Java Province
Get PDFABSTRACT This study aims to analyze the effect of the Human Development Index (HDI), Regency/city Minimum Wage, and Open Unemployment Rate (OUR) on Poverty in East Java Province in 2023. The technique used in this study is multiple linear regression analysis. Based on the results of the analysis, it shows that partially the Human Development Index (HDI) variable has a negative and significant effect on poverty in East Java, while Minimum Wage has a positive and significant effect on poverty in East Java Province. On the other hand, the Open Unemployment Rate does not have a significant effect on poverty in East Java. These findings have important implications for development policy in East Java. Therefore, based on the results of this study, policies that focus on improving human quality through education and health (which support the improvement of the HDI) will be more effective in reducing poverty. Meanwhile, policies related to Regional Minimum Wage need to consider the balance between fair wages and the economic sector's capacity to absorb the workforce. Lastly, although open unemployment is a serious issue, it does not always directly correlate with the poverty rate, as many external factors influence household income.

Teknik yang digunakan dalam penelitian ini adalah analisis regresi linier berganda. Berdasarkan hasil analisis menunjukkan bahwa secara parsial variabel Indeks Pembangunan Manusia (IPM) berpengaruh negatif dan signifikan terhadap kemiskinan di Jawa Timur, sedangkan Upah Minimum Daerah berpengaruh positif dan signifikan terhadap kemiskinan di Provinsi Jawa Timur. Di sisi lain, Tingkat Pengangguran Terbuka tidak berpengaruh signifikan terhadap kemiskinan di Jawa Timur. Oleh karena itu, berdasarkan hasil penelitian ini, kebijakan yang berfokus pada peningkatan kualitas manusia melalui pendidikan dan kesehatan (yang mendukung peningkatan IPM) akan lebih efektif dalam mengurangi kemiskinan. Sementara itu, kebijakan terkait Upah Minimum Daerah perlu mempertimbangkan keseimbangan antara upah yang adil dan kapasitas sektor ekonomi untuk menyerap tenaga kerja. Terakhir, meskipun pengangguran terbuka merupakan masalah yang serius, akan tetapi hal itu tidak selalu berkorelasi langsung dengan tingkat kemiskinan, karena banyak faktor eksternal yang mempengaruhi pendapatan rumah tangga.
