This research explores the effectiveness of a community of inquiry (CoI)-based online course by assessing cognitive, social, and teaching presence. Leveraging a mixed-methods approach, we examine the impact of CoI strategies on learner engagement and learning outcomes. Cognitive presence is evaluated through the depth of critical thinking, social presence through the quality of interpersonal interactions, and teaching presence through instructional design and facilitation. Our study contributes to the understanding of online learning environments, providing insights into the elements that enhance the overall effectiveness of CoI-based courses. The findings offer practical implications for educators, instructional designers, and institutions aiming to optimize online learning experiences.
