Quality Control Systems in Higher Education Supported by the Use of Mobile Messaging Services

This study breaks away from the immobility experienced by quality control systems in higher education. The authors, following the Sustainable Development Goals (SDGs) on quality education set by the United Nations, propose a questionnaire delivery system through mobile messaging services that overcomes the problem of the low response rates of students for these surveys. The research follows an experimental design, is developed over three years, and involves 811 subjects who are distributed in two groups: an experimental group, in which the questionnaires are delivered through mobile messaging services, and a control group. The researchers examine the existence of differences in response rates through a descriptive comparative exploration between the two groups, also applying the Student's t-test to evaluate the significance of the findings. The results reveal that the rates for the experimental group are not only higher than those achieved for the control group but are also significant. The authors conclude that the delivery of surveys through mobile messaging services significantly increases response rates. This fact improves the representativity of the information collected and meets the goals of the quality control system with greater certainty.
