The ability to communicate fluently in English provides numerous advantages, not only in academic settings but also in future professional endeavors. Speaking skills, specifically, are critical in helping individuals express ideas, participate in discussions, and engage in collaborative problem-solving (Crisianita & Mandasari, 2022. Srinivas Parupalli, 2. Moreover. English is recognized as the international lingua franca, further underscoring the need for students to develop strong oral communication skills to compete on a global scale (Kuteeva, 2020. Si, 2. In this context, improving studentsAo speaking abilities in English classrooms has become a central goal for educators worldwide. Despite its importance, many students face significant challenges in acquiring strong speaking skills, particularly in non-native English-speaking countries. The situation at SMA Negeri 2 Kota Tanjungbalai reflects this broader global The students at this school exhibit varying levels of English-speaking proficiency, which creates disparities in classroom engagement and learning outcomes. While some students are confident and capable of participating in speaking activities, others struggle with basic sentence structure and lack the confidence to express themselves in English. This situation not only hampers individual progress but also affects the overall dynamics of classroom Consequently, it has become necessary to explore innovative strategies, such as the integration of technology, to address these challenges and foster an inclusive learning environment (Kumi-Yeboah et al. , 2020. Mhlongo et al. Teaching speaking skills, however, presents unique challenges, especially in classroom settings where students have diverse proficiency levels. For instance, some students may lack foundational vocabulary and grammar knowledge, making it difficult to construct coherent sentences. Others might be capable of understanding English but struggle This work is licensed under a Creative Commons Attribution-ShareAlike 4. 0 International License. English Journal Antartika Volume 2 No. 1 June 2024 with fluency and confidence when speaking aloud (Aizawa et al. , 2. Additionally, traditional speaking activities, such as pair conversations or class discussions, may not be engaging or effective for all learners, especially when these tasks fail to offer personalized feedback. Moreover, time constraints in class often limit opportunities for students to practice speaking sufficiently, leaving gaps in their development of oral communication skills. These challenges highlight the need for innovative approaches to improve students' engagement and effectiveness in acquiring speaking One potential solution to these challenges is the integration of artificial intelligence (AI) technologies specifically designed to enhance language learning experiences. Gemini AI, an interactive AI platform, offers personalized and adaptive speaking practice tailored to each student's proficiency level. By simulating real-life conversations and providing instant feedback. Gemini AI allows students to practice speaking in a low-pressure environment, reducing anxiety and increasing participation. This study aims to evaluate Gemini AI's effectiveness in boosting students' speaking proficiency at SMA Negeri 2 Kota Tanjungbalai. By examining its impact on studentsAo speaking abilities, this research explores how AI can be leveraged to create more inclusive and dynamic language learning experiences (Smith & Carver, 2. Speaking skills are a fundamental component of language learning, as they directly influence learners' ability to communicate effectively in real-world contexts. Speaking is not merely the production of sounds or words, but an interactive process of constructing meaning, requiring a blend of grammar, vocabulary, pronunciation, and fluency (Masuram & Sripada, 2. This multifaceted nature of speaking means that learners must develop both accuracy and automaticity, skills that are often difficult to achieve in traditional classroom settings. In this regard, teaching speaking demands more than just repetition of phrases. it involves the integration of various language aspects and the ability to navigate conversations fluidly, adapting to different situations and speakers (Miftahur Roifah. Eko kusumo. Desi Puspitasari, 2. This theoretical understanding highlights the complexity of speaking skills and suggests that effective teaching methods must address these layers of learning to foster genuine communication ability. One approach that has gained traction in educational theory is differentiated instruction. Differentiated instruction refers to tailoring teaching methods, resources, and learning activities to meet the diverse needs of students, recognizing that learners vary in their abilities, interests, and prior knowledge (Tomlinson, 2. In language learning, differentiated instruction might involve adjusting the speaking task level to match individual students' proficiency levels, ensuring each learner is challenged appropriately. For example, while one student may practice basic sentence structures, another might engage in more complex discussions, achieving progress according to their The flexibility of this approach supports more inclusive learning environments where students feel adequately supported and motivated to improve their speaking skills (Bondie et al. , 2019. Said Al Siyabi & Abdullah Al Shekaili, 2. Differentiated instruction allows educators to foster meaningful speaking practice across a wide spectrum of student competencies by offering varied entry points into language activities. In recent years, integrating technology, particularly Artificial Intelligence (AI), into language education has significantly transformed how students learn and practice speaking skills. AI-powered tools, such as speech recognition software and interactive language platforms, provide learners with opportunities to practice speaking in a low-stakes environment, receiving real-time feedback on pronunciation, grammar, and fluency (Orukpe, 2023. Shafiee Rad, 2. These technologies offer a personalized learning experience by adapting content to individual learners' needs, thus aligning with the principles of differentiated instruction. AI can simulate real-life conversation scenarios, allowing students to practice speaking in various contexts without the pressure of a traditional classroom setting (Warschauer & Grimes, 2. The ability of AI to offer consistent feedback and track progress makes it a valuable tool in enhancing learners' speaking proficiency, particularly in environments where individualized attention from teachers may be limited. Several studies have explored the impact of AI and technology-enhanced learning in language education. A metaanalysis of AI applications in language learning found that students using AI-driven tools significantly improved speaking proficiency compared to traditional classrooms (Xiu-Yi, 2. The use of AI in developing pronunciation accuracy among English learners reports notable gains in student confidence and language competence. These findings suggest that integrating AI into language instruction enhances learners' speaking abilities and boosts engagement and motivation (Widyasari & Maghfiroh, 2. Moreover, research has highlighted the importance of incorporating AI tools in a broader instructional strategy, including teacher guidance and peer interaction (Niyo & Umali, 2. https://ejournal. id/index. php/eja/index English Journal Antartika Volume 2 No. 1 June 2024 Together, these studies provide a strong foundation for further investigation into how AI can be effectively implemented in language education to address diverse learner needs. Research Methodology Classroom Action Research (CAR) was employed in this study to address the challenge of improving students' speaking proficiency using Gemini AI. CAR is a practical approach that allows teachers to experiment with instructional strategies in their classrooms, gather data, and reflect on the outcomes (Rabgay & Kidman, 2. This method was chosen because it aligns with the study's goal of testing a technological interventionAiGemini AIAiin a real-world educational setting. Through iterative cycles of planning, action, observation, and reflection. CAR enables researchers and educators to adapt their teaching strategies based on immediate feedback from classroom interactions (Sato & Chen, 2. This flexibility is particularly important when integrating new technologies, as it allows the teacher to modify the application of AI tools based on student's needs and progress. The participants of this study were 30 high school students from SMA Negeri 2 Kota Tanjungbalai. These students were selected based on several criteria. First, they represented a diverse range of English-speaking abilities, from beginners to intermediate-level learners. The group's heterogeneity was intentional in testing the efficacy of Gemini AI across different skill levels. Additionally, students were selected based on their willingness to participate in an experimental study involving technology in language learning. The selection aimed to include students who had regular access to smartphones or computers outside of class, as this would facilitate their interaction with the AI tool beyond classroom sessions. The study sought to examine how AI could support differentiated instruction in a typical high school environment by involving a mixed-ability group. The research was conducted over four cycles, with each cycle consisting of planning, implementation, observation, and reflection phases. During each cycle, the students engaged with Gemini AI to practice various speaking tasks, such as structured conversations, role-plays, and impromptu speeches. Data was collected through multiple methods, including observational notes, student performance assessments, and semi-structured interviews with participants. These data collection methods were triangulated to ensure validity and to gain a comprehensive understanding of the studentsAo progress in speaking proficiency. Additionally, reflective feedback sessions were held with the students after each cycle to assess their experience with the AI tool and its impact on their confidence and speaking skills. The implementation of Gemini AI was carried out in a structured manner, beginning with an initial assessment to gauge the students' speaking proficiency levels.
