R-PARTNER: um sistema para apoio à realização de experimentos com design do tipo pré-teste e pós-teste em ambientes online de aprendizagem

Abstract

The use of evidence-based practices in education is gaining traction in foreign countries. This trend has been accompanied by the development of a research apparatus responsible for generating and evaluating scientific evidence. To generate evidence, one of the most convincing methods is controlled experiments. However, such experiments are expensive and difficult to carry out. In the Brazilian context, educational research that uses controlled experiments is modest, which weakens the generation of evidence on which to base new educational practices. In this scenario, the present work proposes a system to manage experiments with pretest and posttest designs in online learning environments, seeking to offer better conditions for conducting these experiments. An experiment was conducted to evaluate the user's perception of the system. The results were statistically analyzed and suggest positive user perceptions regarding the system's metrics of ease of use, usefulness, and low time cost. It is concluded that the system is capable of supporting pre-test and post-test design experiments.
