However,...
For the normal probability plots there is a slight evidence of misspecification of two models for the Mathematics performance, the “Only Using MeuTutor” and the “Female” models, suggesting the need for other explicative variables, possibly elements of the MeuTutor; see Figures (f, n).

Confirmed the hypothesis of gender’s influence on adaptive learning environments, by presenting its reliability with other research settings and instruments.
Proposition of models to estimate performance:
To sum up
New hypothesis raised to explain the Mars and Venus Effects related to the design of gamified educational systems.
