This necessitates a systematic investigation into feedback mechanisms in distance education. This systematic review aims to explore the literature on feedback in distance education, focusing on the types, purposes, and timing of feedback, as well as their implementation and impact on students. We conducted a systematic search of relevant databases on May 5, 2024, without applying a publication year restriction, thereby including all eligible studies published up to that date in accordance with PRISMA guidelines. After applying inclusion and exclusion criteria, we included 91 studies and subjected them to content analysis. Existing literature guided the categorization of feedback, examining three dimensions: feedback types, purposes, and timing. Automated systems emerged as the most common source of feedback. Formative feedback was the predominant type, evaluation was the primary purpose, and academic performance was the most frequently measured outcome. Findings highlight the emphasis on feedback’s role in 1 improving student learning outcomes, engagement, and instructional practices. This review synthesizes key findings on feedback mechanisms in distance education, focusing on their critical role in enhancing learning outcomes. It underscores the need for innovative feedback strategies that balance personalization and scalability to address diverse learner needs across contexts. Future research should explore adaptive feedback approaches to ensure inclusivity and effectiveness in distance education settings.  \nKeywords: Distance education, feedback, online learning, PRISMA, online response, online feedback.  \nINTRODUCTION  \nDriven by advances such as AI-powered adaptive learning systems and big data analytics, distance education has revolutionized learning by enabling more personalized interactions between students and instructors. A critical component of this evolution is the development of advanced feedback mechanisms that analyze students’ learning processes in detail and provide personalized feedback. Feedback has emerged as a central focus in contemporary educational research due to its significant impact on evaluating students’ academic performance, increasing motivation, and assessing the quality of the teaching process (Moore & Kersley, 1996). The rapid growth of distance education, driven by technological innovation and unforeseen global challenges, highlights a crucial need for innovative and impactful feedback systems.  \nHattie and Timperley (2007, p. 102) conceptualize feedback as: “information provided by a source/agent (e.g., instructor, peer, book, parent, self, experience) regarding aspects of one’s performance or understanding. A teacher or parent can provide corrective information, a peer can provide an alternative strategy, a book can provide information to clarify ideas, a parent can encourage, and a learner can look up the answer to evaluate the correctness of a response.” In this framework, feedback is understood as a “consequence” of performance.
