An increasing number of studies are evidencing relationships between physical activity (PA) and the mathematical performance of early school students. This is not surprising due to the fact that children grow in all areas simultaneously and their motor and intellectual developments determine each other. Nevertheless, such an approach of combining mathematics education with physical exercises, in addition through play, which is the basis of children's activity and the preferred way of spending time, is still rare at schools. In response to this problem, "Eduball" has been created, which is an educational ball with printed letters, numbers, and other signs used for team mini-games. Surprisingly, despite the studies on general usefulness of Eduball in preschool and early-school education and the effects of physical exercise classes carried out using these balls, still little is known about their impact on mathematical development. Here, we investigate the relationships between the use of Eduball and the acquisition of mathematical knowledge and skills by children. We used a quantitative approach in the form of an experiment in natural settings in which 7-year-old students (first grade) took part (N = 25). For the purposes of this experiment, we created scenarios of physical exercise classes integrated with mathematical contents that used Eduball. Mathematical knowledge and skills were assessed by one of the commonly used tests. The results were compared with the data from the control group of traditional physical education classes (N = 22). As assumed, after a 1-year experiment, students from both groups improved their results, but we found a greater progress in terms of mathematical knowledge and skills in the experimental class compared to the control one. Eduball particularly affected competences related to such mathematical categories as: sets and their elements, multiplication and division, geometric shapes and measuring length, and measuring volume and mass. In sum, our results show that physical exercise classes that used Eduball stimulate the acquisition of mathematical competences by students and, consequently, confirm that there is a strong relation of physical and mathematical development. Therefore, there is a need to review children's educational models, as well as primary school curricula, to combine physical and cognitive activities.

Studies suggest that incorporating core academic subjects into physical education (PE) stimulates the development of both motor and cognitive skills in primary school students. For example, several experiments show that children’s participation in Eduball, i.e., a method that uses educational balls with printed letters, numbers, and other signs, improves their physical fitness while simultaneously developing their mathematical and language skills. However, the question of who should conduct such classes to make them most effective (regular classroom teachers, physical education teachers, or maybe both in cooperation?) remains unanswered. Here, we replicated a previous Eduball experiment, but now, instead of one experimental group, there were three. In the first, Eduball-classes were conducted by the classroom teacher, in the second, by the physical education teacher, and in the third, collaboratively. After one year intervention, all experimental groups significantly improved both their cognitive (mathematical, reading, and writing) and gross motor (locomotor and object control) skills, and these effects were larger than in the control group participating in traditional PE. Importantly, there were no differences in progression between the Eduball-groups. Thus, our study demonstrates that methods linking PE with cognitive tasks can be effectively used by both PE specialists and general classroom teachers.

Despite the general agreement that the interdisciplinary model of physical education (PE), based on the incorporation of core academic subjects into the PE curriculum, stimulates the holistic development of students, there is still a lack of methods for its implementation. Therefore, Eduball was created, i.e., a method that uses educational balls with printed letters, numbers, and other signs. Numerous studies have shown that children participating in activities with Eduballs can develop their physical fitness while simultaneously improving their academic performance, particularly in math and language, including some writing skills. However, little is known about the effects of Eduball on children’s graphomotor skills, which are key for the academic performance of students throughout the entire schooling process. Here, we investigate whether 6-month participation in PE with Eduball stimulates graphomotor skills in primary school students, such as drawing prehandwriting letter patterns on unlined or lined paper and rewriting text on unlined or lined paper. Our results show that the Eduball class (N = 28) significantly improved these skills compared to the control class (N = 26) participating in traditional PE. For example, students from the experimental group wrote with a lower pen pressure and better stability of the line, in contrast to those from the control group. Therefore, this study demonstrates that the Eduball method successfully supports teachers in developing graphomotor skills in children. More broadly, our findings make clear once again that there is the need to integrate physical and cognitive development in education, which can be achieved by using an interdisciplinary model of PE.

The purpose of this study was to evaluate the impact of the BRAINballs program on second graders’ gross motor skills in a primary school in Vietnam. A total of 55 students (23 boys and 32 girls) aged seven years participated in the study. The research used the method of a pedagogical experiment and parallel group technique (experimental and control group) with pre- and post-testing. The study was conducted in the school year 2019/2020. The gross motor skills performance was assessed by the Test of Gross Motor Development—2nd Edition. The BRAINballs program was conducted twice a week and combined physical activity with subject-related contents by means of a set of 100 balls with painted letters, numbers, and signs. The results showed that the experimental and control groups improved their motor skills after one school year (p < 0.001). However, the analysis of covariance demonstrated that students from the experimental group, compared to students from the control group, showed significantly better scores in both subtests: locomotor (p = 0.0000) and object control skills (p = 0.0000). The findings of this study show that the BRAINballs program had a positive effect on children’s motor performances and may help to better understand the development of basic motor skills of seven-year-old students in Vietnam.

The aim of this study is to examine the level of understanding of the principle of fair play by secondary school pupils (n = 827) from the Polish province of Wielkopolska, physical education (PE) students from Poznan University of Physical Education (n = 437), and PE teachers (n = 130). Two structured survey questionnaires were used, namely: The three-level scale known as the Fair Play Moral Dimensions Concept Scale and a Factors of Moral Influence Scale. There were observed differences between male and female students in their comprehension of the principle of fair play regarding the category of sporting activity practiced. The female teachers’ amateur training group more frequently identified the highest level of fair play (32.1% of the examined female teachers) in comparison with their male colleagues. Moreover, differences were noted between boys and girls at the secondary school level. Boys rated the influence of PE teachers and coaches higher, while girls declared that they were more influenced by media and education. For both boys and girls, parents constituted the highest-rated factor of the influence on their moral development. Students also indicated the influence of parents as the highest-rated factor. Among PE teachers, school, as a source of influence on one’s moral development, was awarded higher rates by female than by male teachers. It was observed that parents constituted the highest-rated factor of influence for PE teachers.
