Assessing the Open Trenches in Screening Railway Ground-Borne Vibrations by Means of Artificial Neural Network

2009

Reducing ground borne vibrations in urban areas is a very challenging task in railway transportation. Many mitigation measures can be considered and applied; among these open trenches are very effective. This paper deals with the study of the effect, in terms of reduction of vertical and horizontal displacements and velocities, of the open trenches. 2D FEM simulations have been performed and several open trench configurations have been analysed varying the main geometric features such as width and depth, distance from the rail, thickness of the soil layer over the rigid bedrock, type of the ground, ratio between the depth of the trench, and the thickness of the soil layer. For quantifying t…

Student participation in peer interaction

2021

This study explores how students deal with material resources in their peer interaction when working in pairs in an open-ended problem-solving task. The productive use of material resources can be expected to support successful peer work. However, research into social phenomena in peer interaction is needed in order to identify and describe productive and less productive forms of dealing with material resources as students participate in open-ended problem-solving tasks. Consequently, this explorative study responds to this research need. Based on multimodal data, including video recordings, transcribed talk and the written contributions from four pairs of Year 7 students aged 12-13 years, …

Modeling epidemics through ladder operators

2020

Highlights • We propose an operatorial model to describe epidemics. • The model describes well the asymptotic numbers of the epidemics. • Ladder operators are used to model exchanges between the “actors” of the system.

Classroom effect on primary school students’ self-concept in literacy and mathematics

2019

AbstractAccording to the big-fish-little-pond effect (BFLP) model, high individual academic performance in a particular subject is related to high self-concept in that subject, whereas high average classroom performance has a negative effect on self-concept. In the present study, data from Finnish primary school students in grade 3 (504 students), grade 4 (487 students), and grade 6 (365 students) are used to examine whether the assumptions of the BFLP effect model hold already in primary school. Furthermore, we examined gender differences in BFLP effect. The results showed that as expected students’ high performance in literacy and in mathematics was related to high self-concept in the sam…

Family related variables effect on later educational outcome: a further geospatial analysis on TIMSS 2015 Finland

2020

AbstractFamily-related factors, like parent’s educational level, their values and expectations have a significant impact on child’s early skills and later educational outcomes. Further, parents provide their child, alongside with other learning environments, a broad mathematical and early literacy input. This study investigates the relationship between family-related socio-economic and other factors like, parental education, amount of books at home, parental attitudes towards mathematics and science, parental perception of child’s early skills and student’s later academic achievement. This is studied in the light of the Finnish data collected for Trends in International Mathematics and Scie…

Effects of school-based physical activity on mathematics performance in children: a systematic review

2019

AbstractBackgroundThe benefits of physical activity (PA) on children’s health and wellbeing are well established. However, the benefits of PA on academic performance and particularly on mathematics performance warrant systematic analysis. Mathematics is one of the core subjects in school education globally.MethodsWe systematically searched, analysed and synthesized the literature on the effects of school-based PA interventions on mathematics performance in children aged 4–16. A total of 29 studies consisting of randomised trials and other interventions with control groups were identified through a systematic search, and 11 of them provided sufficient data and appropriate design for a meta-a…

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…

Motivational predictors of students' participation in out-of-school learning activities and academic attainment in science : An application of the tr…

2018

Abstract Given the shortfall in students studying science, promotion of motivation and engagement in science education is a priority. The current study applied the trans-contextual model to study the motivational predictors of participation in science learning activities in secondary-school students . In a three-wave design, secondary-school students completed measures of perceived autonomy support, autonomous and controlled motivation, social-cognitive beliefs (attitudes, subjective norms, perceived control), intentions, and self-reported participation in out-of-school science learning activities. Five-weeks later, students self-reported their science learning activities. Students' science…

The role of parents' and teachers' child-related competence beliefs in the development of students' self-concept of ability

2017

Individuals’ perceptions about their abilities, that is, self-concepts of abilities, are crucial determinants of academic achievement and education-related choices. The aims of this research were to examine the role of parents’ and teachers’ beliefs about children’s abilities in students’ self-concept of ability in the domains of literacy and mathematics, and whether the role of parents and teachers is different among boys and girls, and among low- and high-performing students. These questions were examined using three different data sets: the LIGHT study, the Jyväskylä Entrance into Primary School (JEPS) study and the STAIRWAY study. In all three studies, the participants were Finnish. In …

Zero-Achievers Non-Progressing Studies in Finnish Open University : Three Preventive Factors

2021

Current education policy responds to changes and needs in working life by guiding individuals at different stages of working careers to develop their skills in the spirit of lifelong learning. More and more are applying with hope and enthusiasm to the Open University to strengthen their competence but are unable to get their studies completed. The article explores factors related to the non-progression of studies by students at the Open University in Finland. We call non-progressing students zero-achievers who enroll in studies but do not complete a single credit during the period of course. This research is a descriptive mixed methods study. The research data was collected by an online sur…
