Abstract
Quality assurance and concern for distance learning programmes (DLPs) are necessary due to the
significance of quality control for student satisfaction and enrolment. In light of this, this study investigated
how learners' learning effectiveness (LE) within the institution was impacted by quality assurance
mechanisms (QAM) such as course design (CD), effective teaching and learning (ETL), assessment and
evaluation procedures (AEP), learner support services (LSS), and environmental infrastructure (EI). The study
design that was used was a descriptive survey. 200 students were selected at random from the faculties of
arts, education, and social sciences (FAESS), totalling up the population of 100–500 level students. Part of
the research included a 30-item survey on the Perceived QAM Implementation on LE in Distance Education
Scale (r=.81). The data were analysed with descriptive statistics and the Pearson Product-Moment
Correlation (PPMC) at the 0.05 threshold of statistical significance. The findings demonstrated that CD
(r=0.76), teaching and learning approaches (TLA) (r=0.62), AEP (r=0.57), LSS (r=0.45), and EI (r=0.49) had
positive and significant correlations with students' LE. Also, CD, ETL, AEP, LSS, and EI contributed to students'
LE in the institution. In light of the results, the research suggested that the leadership of the University of
Ibadan's (UI) Distance Learning Centre (DLC) should set up efficient guidelines and a management
framework to handle different facets of quality assurance (QA) and ensure the effective implementation of
these policies to support and improve students' LE. This proactive approach would ensure compliance with
the rigorous demands of 21st-century education. This unique research on QAM and students' LE was carried
out at DLC, UI.
