The Associations Between Leisure-Time Physical Activity and Academic Performance: A Twin Study
2021
Background: Both genetic and environmental influences have been shown to contribute to the association between physical activity and overall academic performance. The authors examined whether leisure-time physical activity (LTPA) shares genetic and environmental variances between spelling, essay writing, reading aloud, reading comprehension, and mathematics in early adolescence. Moreover, they investigated whether genetic polymorphisms associated with physical activity behavior affect these academic skills. Methods: Participants were 12-year-old Finnish twins (n = 4356–4370 twins/academic skill, 49% girls). Academic skills were assessed by teachers, and LTPA was self-reported. Polygenic sco…
The Quality of Maternal Homework Involvement : The Role of Adolescent and Maternal Factors
2021
This study examined adolescent and maternal factors of the quality of maternal homework involvement and the extent to which the factors predicted adolescents' subsequent achievement through adolescents' and mothers' perceptions of the quality of maternal homework involvement. The sample consisted of 847 Finnish adolescents and their 662 mothers who both rated the quality of homework involvement (i.e., autonomy support and psychological control) in the fall of Grade 6. Adolescents rated their positive and negative academic emotions. Mothers rated their beliefs about adolescents' school success, their positive and negative emotions, and adolescents' task avoidance in homework situations. Info…

Selective breeding for endurance running capacity affects cognitive but not motor learning in rats
2012
The ability to utilize oxygen has been shown to affect a wide variety of physiological factors often considered beneficial for survival. As the ability to learn can be seen as one of the core factors of survival in mammals, we studied whether selective breeding for endurance running, an indication of aerobic capacity, also has an effect on learning. Rats selectively bred over 23 generations for their ability to perform forced treadmill running were trained in an appetitively motivated discrimination-reversal classical conditioning task, an alternating T-maze task followed by a rule change (from a shift-win to stay-win rule) and motor learning task. In the discrimination-reversal and T-maze …
Verbal counting skill predicts later math performance and difficulties in middle school
2019
This study examined the role of verbal counting skill as an early predictor of math performance and difficulties (at or below −1.5 standard deviation in basic math skills) in middle school. The role of fourth-grade level arithmetical skills (i.e., calculation fluency, multi-digit arithmetic i.e. procedural calculation, and word problem solving) as mediators was also investigated. The participants included 207 children in central Finland who were studied from kindergarten to the seventh grade. Path modeling showed that verbal counting in kindergarten is a strong predictor for basic math performance in seventh grade, explaining even 52% of the variance in these skills after controlling for th…
Mathematics and Art Connections Expressed in Artworks by South African Students
2022
In this chapter, we examine a collection of drawings, and paintings from South African students between the ages of 10 to 17, that provide fresh and original perceptions to some already known topics, but also several unexpected connections between mathematics and art. These works reference classic math-art connections such as: golden ratio, spirals, infinity, and geometric figures; they also contain several personal reflections, unique discoveries and references to ethnomathematical connections within the African cultural heritage. To introduce their pieces and themselves, students shared their own interpretations of their artworks. These commentaries make possible the identification of cog…
The Role of Teacher Closeness in Emotions and Achievement for Adolescents With and Without Learning Difficulties
2022
Student–teacher relationships are crucial for adolescents’ adjustment in the school context. The aim of the present study was to examine the role of teacher closeness in academic emotions and achievement among adolescents with and without learning difficulties during the first year in lower secondary school. Students’ learning difficulties (LDs) were identified based on tested reading and math skills. In addition, students evaluated their teacher relationships and rated academic emotions in literacy and math domains. The results indicated that higher teacher closeness was related to increasing positive emotions and increasing literacy achievement during seventh grade, whereas lower levels …

Leisure-time physical activity and participation in organized sports : changes from 1985-2014 in Finland and Norway
2019
Participation in organized sports is a popular and important part of the lives of children and adolescents and is associated with improved psychological and social health, as well as an increased likelihood of meeting physical activity (PA) recommendations. Changes in modern society, including increased car ownership and use of technology and electronic media, have led to an additional focus on the importance of health‐enhancing PA among children and adolescents. The aim of this article was to study the secular changes in self‐reports of participation in organized sports clubs and leisure‐time vigorous physical activity (LVPA), and whether the relationship between participation in organized…
Ideas for using GeoGebra and Origami in Teaching Regular Polyhedrons Lessons
2018
The approach of combining GeoGebra and origami is well accepted among students in the school "Petro Kuzmjak" where it is used to teach geometry lessons. This article elaborates on how to introduce students (upper elementary and high school students, age 14-18) to Platonic solids and their properties through combination of GeoGebra and origami activities. Some of the important mathematical concepts related to these well-known geometrical solids can be explained to students applying hands-on activities along with educational software. peerReviewed
