Notable gains have been made in understanding the factors that influence the student experience in higher education, particularly in the area of student engagement. While tremendous effort has been focused on identifying educationally beneficial activities for students, we must also consider where these activities are occurring. In recent years there have been technological advances that have paved the way for blended learning environments, however, physical learning environments continue to dominate the functionality of many universities. The development of purpose‐built informal social learning spaces as a strategy to enhance the student experience is becoming more prevalent, although empirical research in this area is lacking. This study explores the role of social learning spaces on the student experience using the student engagement framework within a qualitative research design. Informal interviews with 103 students were conducted within a social learning space. Findings reveal that social learning spaces can contribute to enhanced student engagement by fostering active learning, social interaction and belonging amongst tertiary students. The study also suggests that design is a contributing factor to students' perceptions of social learning spaces. 相似文献

In a move away from the open or low-fenced grounds that have traditionally been a feature of Australian school design, the last decade has seen a growth in the installation of high-security fences around schools. These structures, far from being passive and neutral, act to redefine the possibilities for movement and connectivity in the local landscape. This paper looks beyond the impact of fences on safety and security to explore the wider implications of these structures. By bringing together perspectives on children’s experience of independent mobility, belonging and attachment to place, the paper opens up new avenues for thinking about how children’s learning is shaped by the relationship between school, community and the boundaries between them. It provides a starting point for understanding how high-security boundaries can impact on children’s learning and why at times these structures may pose more risks than those they aim to address. 相似文献
