*1.4. Objective*

The objective of this research is to explore whether the social dimension of physical space in educational settings explains a student's academic results through a postoccupancy evaluation design.

#### **2. Materials and Methods**

The research was conducted using a quantitative approach that sought to understand the perception of students regarding their satisfaction with their indoor environment and its ability to foster learning interactions.

First, appointments were arranged with each dean or person in charge of infrastructure to visit centers to identify the learning space designs. Figure 1 shows selected classrooms and their diversity in layout design, lighting typology, furniture, information technology support, etc. Then, the professors who teach in these classrooms were identified, and they were contacted to determine their availability for applying the data collection instrument to their students. The purpose of the study and the average time of responding to the questionnaire were indicated. Consequently 21 of the 30 groups were able to establish a date to conduct the test.

The Learning Environment and Social Interaction scale (LESI) was provided in hard copy, and the students' answers were entered into a digital spreadsheet (educational Microsoft Excel 365).

The analysis of data consisted of a description of the sample, the reliability and validity, and prediction of the Grade Point Average (GPA) from IEQ satisfaction and learning interaction. First, the mean value and the standard deviation were defined to determine the empirical framework. Then, Cronbach's Alpha and Exploratory Factor Analysis were conducted to evidence the reliability and the construct validity of the data collection instrument. Finally, multiple linear regression was calculated to identify which items of the scale could predict academic performance and to what extent. The linear independence of predictor variables and the homoscedasticity of residuals were checked.
