Use of mobile devices and their relationship with academic performance and student behavior in Business Management Engineering students at the Instituto Tecnológico de Nuevo León

This study analyzed the relationship between mobile device use, academic performance, and student behavior among Business Management Engineering students at the Technological Institute of Nuevo León. A mixed-methods, descriptive-correlational design was employed through a self-administered questionnaire applied to 300 students and a focus group with 25 participants. Results revealed that 61.7% of students frequently used mobile devices for academic purposes; however, social media and entertainment remained common non-academic activities. Additionally, 69.4% reported being easily distracted while studying, and 64.3% acknowledged procrastination behaviors associated with device use. Spearman correlation analysis identified a significant negative relationship between distraction and academic performance [rs = -0.124, p = .032], and a positive relationship between sleep duration and academic performance [rs = 0.137, p = .030]. Findings suggest that the educational impact of mobile devices depends largely on students self-regulation and patterns of use.
