Abstract. This systematic review examines the integration of research-based strategies (RBS) in language education, focusing on their role in enhancing students' academic literacy and sentence construction skills while addressing challenges and opportunities. A qualitative research design was employed to synthesize findings from existing studies, providing a comprehensive understanding of RBS's impact. Articles published between 2020 and 2024 were identified through databases such as ERIC, JSTOR, and SAGE Journals. Using the PRISMA methodology, 429,096 records were screened for relevance, accessibility, and adherence to predefined inclusion criteria, resulting in the selection of 59 studies for in-depth analysis. Findings reveal that RBS significantly improves sentence construction by fostering structured writing, peer collaboration, and iterative feedback. However, challenges such as limited research preparedness, high cognitive demands, and insufficient instructional support hinder optimal implementation. Opportunities lie in collaborative research projects and the integration of digital tools, which promote active engagement and practical applications of linguistic principles. The study underscores the necessity of curriculum redesign, targeted teacher training, and institutional support to maximize RBS's potential in language education. These strategies align with 21st-century educational goals, emphasizing critical thinking, problem-solving, and collaboration. By bridging theoretical and practical learning, RBS equips students with essential academic and professional skills. This review provides valuable insights into the effective integration of RBS in language instruction, advocating for learner-centered approaches that address implementation barriers and leverage emerging opportunities. It contributes to the understanding of how innovative, research-driven methodologies can transform language education and enhance student outcomes. This review uniquely contributes to the field by synthesizing recent evidence to provide actionable recommendations for bridging theoretical and practical aspects of language instruction, particularly emphasizing the potential of RBS in fostering 21st-century skills such as critical thinking and collaboration. Its insights support curriculum redesign, targeted teacher training, and institutional investment to overcome implementation barriers and leverage emerging opportunities. These strategies align with modern educational goals, equipping students with essential academic and professional skills.
