Kwaliteit van bewegingsonderwijs:op naar een gedragen visie binnen de gemeente Groningen

Met de pilot ‘Bewegen voor kinderen’ wordt ingestoken op het bewegingsonderwijs op de basisschool, en daarmee het binnenschoolse aanbod. Op deelnemende scholen krijgen alle groepen 3 t/m 8 tweemaal per week bewegingsonderwijs van de vakleerkracht. Diezelfde vakleerkracht verzorgt ook tweemaal per week een naschools aanbod. Zoals in de raadsbrief benoemd is het doel de kwaliteit van het bewegingsonderwijs en het buitenschoolse sport- en beweegaanbod te verbeteren. De aanleiding voor dit onderzoek is te vinden in de doelstelling: met het project wordt beoogd de kwaliteit te verbeteren. Maar wat is dan kwaliteit? Wanneer is er sprake van een goede of hoge kwaliteit? Welke factoren of criteria spelen hierbij een rol? De kernvraag binnen dit onderzoek luidt dan ook: Wat vinden beleidsmakers, leerkrachten en schooldirecties de belangrijkste criteria voor de kwaliteit van bewegingsonderwijs? In deze publicatie worden de belangrijkste bevindingen en adviezen uiteengezet

Who\u27s to Blame? How Attributions of Blame Impact Perceptions of Effective Leaders

The objective of this study was to examine third-party observers’ perceptions of a coach and the leadership qualities that he exhibited when he engaged in different attributions of blame in a high-stakes scenario. When a leader blames himself for a negative outcome, there may be a link to transformational leadership such that the leader is actively caring about the well-being of his followers and putting them first. In contrast, when a leader blames one of his followers for a negative outcome, there may be a link to transactional leadership such that he is putting responsibility on a follower and dealing with an immediate concern (Eberlin & Tatum, 2008). Most of the research regarding leadership styles and blame has been conducted regarding businesses, so the current study aims to extend this research into a sport context by having undergraduate university participants (N = 57) read a scenario about a high school football player and his coach. Both individuals make a number of mistakes that result in the football team’s disqualification from the state playoffs. Individuals either read that the coach blamed the player for the disqualification, or that he blamed himself. Results showed that the coach was seen as more transformational and more competent when engaged in self-blame but was not seen as more transactional when engaged in player-blame. Additionally, results showed that all participants, regardless of condition, attributed the most blame to the player. The findings from the current study can inform best leadership practices in a sport context, as well as provide information on how undergraduate university students perceive effective leadership in relation to attributions of blame

Physics of Resonating Valence Bond Spin Liquids

This thesis will investigate various aspects of the physics of resonating valence bond spin liquids. After giving an introduction to the world that lies beyond Landau\u27s priciple of symmetry breaking, e.g. giving an overview of exotic magnetic phases and how they can be described and: possibly) found, we will study a spin-rotationally invariant model system with a known parent Hamiltonian, and argue its ground state to lie within a highly sought after exotic phase, namely the Z$_{2}$ quantum spin liquid phase. A newly developed numerical procedure --Pfaffian Monte Carlo-- will be introduced to amass evidence that our model Hamiltonian indeed exhibits a Z$_{2}$ quantum spin liquid phase. Subsequently, we will prove a useful mathematical property of the resonating valence bond states: these states are shown to be linearly independent. Various lattices are investigated concerning this property, and its applications and usefullness are discussed. Eventually, we present a simplified model system describing the interplay of the well known Heisenberg interaction and the Dzyaloshinskii-Moriya: DM) interaction term acting on a sawtooth chain. The effect of the interplay between the two interaction couplings on the phase diagram is investigated. To do so, we employ modern techniques such as the density matrix renormalization group: DMRG) scheme. We find that for weak DM interaction the system exhibits valence bond order. However, a strong enough DM coupling destroys this order
