A simple mechanical model for simulating cross-country skiing,skating technique

The role of simulation models in sport disciplines has become relevant lately due to the multiple advantages that they may offer sports teams, coaches and practitioners. This paper develops and presents a simple three-dimensional multibody dynamic model of a cross-country skier, modeling a single propulsion phase to obtain the kinetic parameters involved in the movement. A professional Olympic-level skier performed the skating technique without poles in a ski tunnel under controlled conditions and on an incline plane. Then, with a force acquisition system attached to the ski bindings and a motion capture system set on site, the leg resultant forces and the movement of specific points of the skier’s lower body were acquired. The data obtained from the motion capture system were used as the prescribed kinematic input data in the multibody model and the measured force was used later as a parameter of comparison with the results of the simple model. After simulating the technique, the calculated resultant forces seem to be in agreement with those measured in the field.     

The implications of teachers’ implicit theories for moral education: A case study from Finland

Implicit theories concerning the malleability of human qualities are known to have a powerful impact on motivation and learning, but their role in moral education is an under-researched topic. In this qualitative case study, we examined the impact of implicit theories on four Finnish teachers’ practices of teaching morally and in teaching morality. The data include preliminary and stimulated recall interviews (STR) as well as classroom observations. Our results demonstrate the multiple ways in which teachers’ implicit beliefs are communicated to students and influence teacher’s interpretations and endeavors to educate the ethical capabilities of students. The study provides evidence for the claim that implicit theories are an important construct which has been missing from the moral education literature. Directions for future research are suggested.     

A framework of industrial knowledge spillovers in big-science centers

We employed the grounded theory method to construct a framework describing the distinctive mechanisms through which big-science centers generate industrial knowledge spillovers in the economy. Our focus is on large-scale big-science installations typically associated with experimental physics. We draw on social network, social capital, and inter-organizational learning theories to examine knowledge spillovers accruing to industrial partner companies in big-science-industry dyads. The context for the study is provided by CERN’s new particle accelerator project, the Large Hadron Collider (LHC). In addition to building a grounded theory framework for the study of industrial knowledge spillovers, our study demonstrates the distinctive potential that big-science centers offer as a source of knowledge spillovers in national innovation systems.     

Changes in the cross-country ski base properties resulting from the ski use

In this work, changes in the cross-country ski base properties resulting from stone grinding, skiing, waxing and re-stone grinding have been investigated. The surface topography, crystallinity, wettability and sliding properties of cross-country ski bases were recorded using a selection of measurement techniques: non-contact chromatic confocal microscopy, contact-type surface roughness analyser and scanning electron microscopy (topography), Raman spectroscopy (crystallinity), contact angle measurement (wettability) and a ski tester (sliding properties). The tested skis were used for 150 km and waxed 35 times. The ski base surface became smoother and the orientation and crystallisation of the base material increased. Wear decreased the hydrophobicity and increased the sliding friction. Even though re-grinding did not restore all of the ski base properties, re-grinding improved the wettability and sliding properties. The results help to optimise stone grinding interval to maintain the performance of the skis.     

Validation of portable 2D force binding systems for cross-country skiing

The aim of the present study was to design, construct and scientifically validate a two-dimensional force measurement binding system for cross-country skiing. The system consists of two force measurement bindings. One binding was designed for analysing classic skiing (vertical and anterior–posterior [along the ski] force components) and the other one for skate (freestyle) skiing (vertical and medio-lateral [transverse to the ski] force components). Validation was accomplished using a three-step process: (1) accuracy tests for the sensors in two temperatures, (2) sport-specific imitation jump test on standard force plates in a laboratory and (3) comparing the system against force measurement reference systems that are currently used when skiing on snow. During sport-specific imitation jumps, differences in peak forces and impulses between the classic binding and the reference systems ranged from 8.0 to 19.9 % and were two to three times greater compared to differences between the skate binding and the reference systems (range ?5.9 to 5.5 %). However, high similarity coefficients were observed with both bindings (classic binding 0.990–0.996, skate binding 0.996–0.999) compared to the reference systems. Based on these results, the skate binding was shown to be fully valid for use in field measurements of skate skiing, whereas some improvements have to be performed in the construction and sensor placements for the classic binding (vertical as well as anterior–posterior force component).     

Students' Pedagogical Thinking and the use of ICTs in Teaching

This article discusses students' pedagogical thinking in situations where the use of information and communication technologies (ICTs) has a (well-defined) pedagogical role and rationale. By analysing students' pedagogical thinking in this setting, it is also possible to better understand their motivations and self-regulation. Pedagogical thinking as viewed from the student's angle is a new area of educational research. Our research method is a combination of the Stimulated Recall interview and the semi-structured theme interview. In addition, some background data were gathered by questionnaire to discern students' different uses of ICTs and their contexts. The findings suggest how the educational use of ICTs is considered to be meaningful and motivating by both genders and among all the interviewed age groups, in spite of the fact that an acute and vocal critique seems to develop among older students. The differences reside in students' reasoning regarding decision making in task operations between genders, which was one of the background variables—girls actively include identity and opinion, while boys emphasize the quality of performance as motives for decisions.     

The role of growth mindset in shaping teachers' intercultural competencies: A study among Finnish teachers

Cultural heterogenisation of classrooms and existing achievement gaps have led to an acknowledgement of the need to develop teachers' intercultural competencies. A growth mindset (a belief that intelligence, personality and other such qualities can be cultivated) predicts positive intergroup attitudes and reduces stereotyping, but has not been researched as an aspect of teachers' intercultural competence. This study analyses the role of growth mindset in shaping three aspects relevant to teachers' intercultural competencies: process versus trait orientation to students, diversity beliefs and orientation to social justice and equity. Fifteen Finnish comprehensive schoolteachers were interviewed. Significant differences were found between teachers with fixed and growth mindsets. Teachers with a growth mindset were more likely to hold polyculturalist beliefs about the interconnectedness and changeability of cultures, and to recognise and combat issues of social injustice and inequity. Teachers with a fixed mindset made trait-focused interpretations of their students and did not easily recognise problems of social justice in school or in society. These results encourage us to suggest that a growth mindset is a construct with a lot of potential to introduce novel approaches to multi/intercultural and social justice teacher education, but more research is needed. The implications of the findings for teacher education and further research are discussed.     

Developing religious identities of Muslim students in the classroom: a case study from Finland

In the Finnish National core curricula for religions, the aims of religious socialisation have been replaced with aims of personal identity development. This shift of aims is also prevalent in many other countries, but the practical implications of it are not clear. This paper presents the results of a case study examining different ways of supporting the development of Muslim students’ religious identities in the classroom, and discusses these observations in the light of different interpretations concerning the possibilities and practices of religious identity development in liberal religious education.     

Teaching Islamic education in Finnish schools: A field of negotiations

The challenges of contemporary multicultural societies have resulted in changing aims for religious education and the necessity to adjust teacher education accordingly. The processes of negotiation related to the coexistence of different religious and cultural groups are intertwined in the Finnish curriculum for religious education. This case study examines three Islamic education teachers who negotiated intra- and inter-religious tensions as well as tensions between societal and religious orientations of education. Through their ideological, pedagogical and interpersonal negotiations teachers can mediate the contested practices of Islam as well as the ideals of liberal democracies and contribute to the emergence of Finnish Islam.     

Economic Recession,Teacher-Reported Cuts to School Resources,and Children's Economic and Psychiatric Problems in Young Adulthood

The study investigated whether cuts to school resources made during economic recession contribute to children's psychiatric and economic problems in early adulthood. The cohort consisted of 817 Finnish children. Data was gathered from teachers during a recession (child age 12) and from national registers on children's post-recession use of psychiatric and income benefit services (age 18–28). Children's need for remedial instruction, special education, or psychosocial services was associated with later use of income support and psychiatric services. Those receiving special education had an increased risk for adulthood use of psychiatric services as compared to those who needed, but did not receive, this service. A decrease in material resources and teachers' loss of motivation predicted children's later use of psychiatric services.
