Purpose: Systematic efforts to study students' use of informal learning spaces are crucial for determining how, when and why students use such spaces. This case study provides an example of an effort to evaluate an informal learning space on the basis of students' usage of the space and the features within the space. Design/methodology/approach: Use of heatmap camera technology and a semi-structured interview with a supervisor of an informal learning space supported the mixed-methods evaluation of the space. Findings: Findings from both the heatmap outputs and semi-structured interview suggested that students' use of the informal learning space is limited due to the location of the space on campus and circumstances surrounding students' day-to-day schedules and needs. Practical implications: Findings from both the heatmap outputs and semi-structured interview suggested that students' use of the informal learning space is limited due to the location of the space on campus and circumstances surrounding students' day-to-day schedules and needs. These findings are actively contributing to the authors' institution's efforts surrounding planning, funding and design of other informal learning spaces on campus. Originality/value: While most research on instructors' and students' use of space has taken place in formal classrooms, some higher education scholars have explored ways in which college and university students use informal spaces around their campuses (e.g. Harrop and Turpin, 2013; Ramu et al., 2022). Given the extensive time students spend on their campuses outside of formal class meetings (Deepwell and Malik, 2008), higher education institutions must take measures to better understand how their students use informal learning spaces to allocate resources toward the optimization of such spaces. This mixed-methods case study advances the emerging global discussion on how, when and why students use informal learning spaces.
