[Vail et al., 2015]

Of all the learner characteristics that are known to influence the effectiveness of adaptive support, gender is one of the most widely recognized.

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

In several domains: Mathematics; Introduction to Computer Programming.

[Arroyo et al., 2011, 2013]; [Vail et al., 2015]

Gender difference in the use of intelligent educational technologies:

According to these studiesThere is a difference in:

Behavior; Attitude; Learning and; Emotion based on the gender.

Cognitive levels: Conceptual and problem-based approaches; Affective assistance (motivation and engagement)

[Arroyo et al., 2011, 2013]; [Vail et al., 2015]

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

Gender Difference Studies: Usually performed as lab studies; Few studies investigated the gamification support; Only some studies about language course (but no Portuguese); No experimental study with ecological settings in Brazil; No model to estimate Math and Portuguese performance based on

gender.

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

the use of an adaptive learning technology improves student’s performance in Mathematics and Portuguese for both male and female students (p-Value < .05).

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

The improvement of male student’s performance is more significant (p-Value < .05)

Male Female

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

When we focus on technology, male students had better performance in mathematics (21%), but no significant difference in Portuguese.

Beta regression model

The response variables of the models are:

Ymath (Math performance);

Yport (Port performance).

The mean Yport or Ymath,

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

Beta regression model

Where:

is the linear predictor;

is the sample size;

is the individual;

is an unknown vector parameter;

are fixed covariates .

Can be written as:

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

Almost all covariates are significant at the 5% nominal level (p-Value < .05), except Gender for

the performance model in Portuguese.

Beta regression model

The systematic components of the models were defined by the following mathematical expressions:

Beta regression model

Other six models, only considering the significant covariates

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

In this case:

If a model is correctly specified we expect that the residuals are randomly scattered around zero in the plots of residuals against observations index.

The residuals graphical analysis

It is essential to validate the aforementioned conclusions

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

The normal probability plot with generated envelope:

Can be used even when the empirical distributions of the residuals are not normal;

If the model fits well, we expect that most of the residuals fall within the band;

Are based on the differences between the observed responses (y) and its fitted value ().

Another residuals graphical

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

In figures

See: a, e, I, m - c, g, l, o

It is possible to notice that the residuals are randomly scattered around zero (no systematic features) in all plots of the combined residual against the observations index, for both Math and Portuguese models.

| www.nees.com.br/enIg Ibert Bittencourt | ig.ibert@ic.ufal.br

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).
