<p>To explore effective learning design for students’ cognitive engagement, a design-based case study was conducted in a quality control course in the Costa Rican National University of Distance Education between the 2011 and 2012 academic years. The course was revised for the 2012 provision in terms of the assignment structure, the number of face-to-face sessions, and facilitation strategies. This study documents how the course redesign impacted the distance learners’ cognitive engagement and learning outcomes. Theories of cognitive engagement and transactional distance informed the design-based investigation. Research findings indicate that the design revisions positively influenced both students’ cognitive engagement and learning outcomes within this distance higher education context; however, the student performance represented by their assessment grades might not always reflect this improvement.</p>

Drawing upon cultural-historical activity theory, this research analyzed the structural contradictions existing in a variety of educational activities among a group of alienated adult students in Korea National Open University (KNOU). Despite KNOU's quantitative development in student enrollment, the contradictions shed light on how the institution's top-down, bureaucratic pedagogical system collided with individual expectations and needs. In particular, the participants' critical viewpoints demonstrate the incompatible social roles that the open and distance higher education institution plays in Korean society. For example, while KNOU contributes to extending higher education opportunities for those who have unmet educational needs, the value of the KNOU degree has not been socially acknowledged since there is little, if any, competition in the entrance process. This study also documents how these contradictions were culturally and historically embedded in the participants' distance higher education activities. Given the persistent contradictions, the research findings illuminate that KNOU's efficiency-oriented model has not effectively facilitated the students' learning as its distance higher education system is inevitably based on a compromise between a competitive, quality curriculum and the efficient extension of audiences.
