A eficácia do software OPENDNS no controle de acessos indevidos em laboratórios de informática: uma pesquisa-ação no CETI Professor Milton Aguiar

Abstract

This research evaluated the use of the OpenDNS software to control inappropriate access in the Computer Laboratory of CETI Professor Milton Aguiar, in Teresina-PI. The objective was to identify the frequency of access to inappropriate content (such as social networks and non-educational websites) and to evaluate how blocking these sites improved class flow and student attention. The methodology used was action research, with a qualitative and quantitative approach. The study had two phases: an exploratory phase (to understand internet usage before the filters) and a descriptive phase (to evaluate the results after using the tool). Data was collected by analyzing the OpenDNS access records (logs) and the teacher's responses to diagnostic and evaluation questionnaires. The results showed that the system successfully blocked inappropriate content (such as adult and violent websites) and reduced access to online games, despite some technical difficulties in blocking certain social networks. It is concluded that the use of the software greatly facilitated class management, reducing the need for the teacher to constantly monitor the screens. This created a safer and more focused learning environment, and the continued use of the system in the school is recommended.
