Indicators of sailing performance in youth dinghy sailing

Abstract

This study aimed to determine indicators of sailing performance in 2 (age) groups of youth sailors by investigating the anthropometric, physical and motor coordination differences and factors discriminating between elite and non-elite male optimist sailors and young dynamic hikers. Anthropometric measurements from 23 optimist sailors (mean ± SD age = 12.3 ± 1.4 years) and 24 dynamic youth hikers (i.e. Laser 4.7, Laser radial and Europe sailors <18 years who have to sail the boat in a very dynamic manner, due to a high sailor to yacht weight ratio) (mean ± SD age = 16.5 ± 1.6 years) were conducted. They performed a physical fitness test battery (EUROFIT), motor coordination test battery (Körperkoordinationstest für Kinder) and the Bucket test. Both groups of sailors were divided into two subgroups (i.e. elites and non-elites) based on sailing expertise. The significant differences, taking biological maturation into account and factors discriminating between elite and non-elite optimist sailors and dynamic hikers were explored by means of multivariate analysis of covariance and discriminant analysis, respectively. The main results indicated that 100.0% of elite optimist sailors and 88.9% of elite dynamic hikers could be correctly classified by means of two motor coordination tests (i.e. side step and side jump) and Bucket test, respectively. As such, strength- and speed-oriented motor coordination and isometric knee-extension strength endurance can be identified as indicators of sailing performance in young optimist and dynamic youth sailors, respectively. Therefore, we emphasise the importance of motor coordination skill training in optimist sailors (<15 years) and maximum strength training later on (>15 years) in order to increase their isometric knee-extension strength endurance.     

Assessing and developing critical-thinking skills in higher education

Generic skills such as critical thinking, problem solving, and communication are essential for students' success in higher education and their careers. This article presents findings from an international study of students' (n ≈ 120,000) generic skills from six countries using a performance-based assessment. Results indicate that higher education students, on average, gain generic skills between entry and exit. However, learning gain is less marked than could be expected and varies significantly among country samples. Various background variables such as gender, ethnicity, parental level of education, and primary language are also explored. The authors conclude that it is feasible to reliably and validly measure generic skills in a cross-cultural context and that assessment of these skills is an essential component of best practices in higher education.     

Reaching a Consensus on the Definition of Genetic Literacy that Is Required from a Twenty-First-Century Citizen

To determine what knowledge of genetics is needed for decision-making on genetic-related issues, a consensus-reaching approach was used. An international group of 57 experts, involved in teaching, studying, or developing genetic education and communication or working with genetic applications in medicine, agriculture, or forensics, answered the questions: “What knowledge of genetics is relevant to those individuals not professionally involved in science?” and “Why is this knowledge relevant?” The answers were classified in different knowledge components following the PISA 2015 science framework. During a workshop with the participants, the results were discussed and applied to seven cases in which genetic knowledge is relevant for decision-making. The analysis of these discussions resulted in a revised framework consisting of nine conceptual knowledge components, three sociocultural components, and four epistemic components. The framework can be used in curricular decisions; its open character allows for including new technologies and applications and facilitates comparisons of different cases.     

Moral authorship of novice teachers in primary education

This article focuses on moral authorship as an element of the professional development of novice teachers in the Netherlands. Moral authorship refers to the ability of teachers to observe, identify, verbalize and reflect on the moral aspects of their work in a proactive and dialogical manner. We elaborate on moral authorship by theoretically exploring six interdependent tasks of moral meaning making: moral commitment, awareness, orientation and positioning, moral performance and evaluation. Narratives of 19 novice teachers were analyzed to explore moral authorship in teachers’ talk. The results show the opportunities of moral authorship to support, navigate, and reinforce the professional development of novice teachers. This study suggests professional self-dialogs for enhancing the development of moral authorship.     

Identifying pathways of teachers’ PCK development

This paper describes a method of analysing teacher growth in the context of science education. It focuses on the identification of pathways in the development of secondary school teachers’ pedagogical content knowledge (PCK) by the use of the interconnected model of teachers’ professional growth (IMTPG).The teachers (n = 12) participated in a one-year action research project focused on their individual concerns related to teaching science. The use of the IMTPG revealed that teachers use different pathways of learning to develop different aspects of their PCK. For each PCK component, three distinct pathways could be identified, two of which clearly were associated with professional growth. When examining these two pathways in detail, it was found that (1) teachers learned about new instructional strategies and assessment methods mostly through literature reviews and discussions with peers and (2) teachers who analyzed and reflected on student learning as it happened in their classrooms developed understandings that helped them to select and apply instructional strategies to further promote student learning. Both the analytical method as well as the identification of the different developmental pathways help to better understand teacher development in the context of classroom practices.     

Designing for communication at work: A case for technology-enhanced boundary objects

In this article we conceptualise the challenges of communication between a mortgage company and its customers in terms of crossing boundaries between communities. Through an ethnographic study we first address the question: what are the challenges of communication between sales agents and customers of a mortgage company around mathematical artefacts? Insight into these challenges formed the basis for an intervention in which we designed technology-enhanced boundary objects (TEBOs) that were reconfigurations of problematic symbolic artefacts. Secondly, we ask what the sales agents learned from the intervention. The data suggest that the intervention with the TEBOs helped employees to develop a better understanding of the mathematics behind the mortgages they sold, and to improve communication with their customers.     

Web 2.0 and competence‐oriented design of learning—Potentials and implications for higher education

This paper discusses the potential of learning technologies to foster competence development of students. It aims to improve understanding of pedagogical conditions that have to be met to establish a competence orientation in e‐learning. We review the literature to summarise recent changes in e‐learning, identify attributes of web 2.0 technologies, revisit the concept of competence and specify implications for the competence‐oriented design of learning environments. By referring to Kolb's learning cycle, we illustrate this view with a case study on the use of Google Apps as collaborative learning environment and recommend how competence‐oriented e‐learning activities can be created. Our findings reinforce the position that web 2.0 tools enable a shift from a distributive to a more collaborative mode in e‐learning. In particular, the ease of use and intuition of web 2.0 technologies allow creating learning environments, which realise activity‐rich pedagogical models and facilitate competence development of students. The paper concludes that, despite the demand of firms for versatile graduates and the obvious potential of learning technologies to foster competence development of students, universities need to establish institutional strategies to make this pedagogical change happen.     

On Subject Variations in Achievement Motivations: A Study in Business Subjects

Student achievement motivations are crucial in learning in two ways: as a determinant and an aim of learning. In this study, we focus on two related questions with regard to achievement motivations: to what extent are they subject-specific, and to what extent are they malleable? Answers to both questions are especially important when aiming to influence motivations. Malleability of motivation is studied by designing structural equation models that explain achievement motivation out of the most stable student characteristics one can think of: gender, and personality traits. Subject matter variability is studied by estimating these models for five main subject areas in a business program. The motivation construct we use is based on the expectancy-value model and distinguishes four different facets: cognitive competence, difficulty, task-value and affect. We find evidence for strong subject-specificity and considerable non-malleability of achievement motivation; part of that last aspect is a remarkably constant over-confidence gender gap present in the data of the calibration of competency beliefs and performance in all subject areas.
