Abstract
Behavioural study and testing the consequences of inappropriate usage of computers at lectures.
Observational studies of classrooms and surveillance of students made ground for experimental tests.
Control group and interventional group was established, to later make a chi-square test, to check for statistical significance. Results showed that the intervention group had approximately 27% worse score on a test, if they were ‘distracted’ by common tasks, that were to be solved on computer while following a lecture.
