In this research, a study is made of the effect of the application of Pólya's problem-solving heuristic on the development of geometric skills and its impact on academic performance. In the intervention, the topic of angles was developed, to a section of 25 fourth grade high school students in an educational center in the Municipality of Yamasá of the Monte Plata Province in the Dominican Republic. A quasi-experimental type design with a quantitative approach and correlational scope was used, with a non-probabilistic sample, with an intact group and a pre-test and post-test design. The results show that, through Pólya's problem-solving heuristic, students expanded their skills in geometry that greatly increased learning about angles. Corroborated by a growth in the average of the grades from 62.4% that was obtained in the pre-test, to 83.7% that was reached in the post-test, showing statistically that there are significant differences. It stands out that the Pólya heuristic was highly valued by the students under study, therefore, it is believed that it had a positive influence on the benefit of their learning about angles. In addition, the results of the post-test reveal that there is no relationship between the sex of the group under study and the scores obtained when the Pólya heuristic is applied.

Nowadays, most children play digital games. Digital games, despite their advantages, have gradually eroded the existence of traditional games. Although both digital and traditional games comprise the values of problem-solving learning for children, traditional games offer more benefits in terms of the embodiment of local wisdom. This study aimed at encompassing the influence of Javanese traditional games such as bekelan, congklak lidi, and selentikan on the improvement of children’s problem-solving skills. This research was done employing quasi-experimental design involving 72 school-age children ranging from 9 to 11 years old, who studied at primary schools. The subjects of this study consisted of four experimental groups. Three groups played bekelan, congklak lidi, selentikan games respectively and the other group was assigned as the control group. The treatment was done for three weeks divided into six sessions. The findings showed that there was a significant improvement between the result of the pre-test and that of the post-test for these three games. The analysis results using One Way ANOVA showed that there was a difference in the improvement of problem-solving skills among groups (F(17) = 5.032, p < .01). Due to its superiority, Javanese traditional games are potential to be an alternative media in improving children’s problem-solving skills.
