Good job! - giving positive feedback in EFL lessons : comparison of primary and secondary school

2013

Tämän tutkimuksen tarkoituksena on selvittää, miten positiivista palautetta annetaan ala- ja yläkoulussa ja vertailla näitä kahta kouluastetta. Tutkimuksen lähtökohtana on, että alakoululaiset saavat positiivista palautetta enemmän kuin yläkoululaiset. Yksi keskeisistä kohteista on vertailla, kuinka opettajien ja oppilaiden näkemykset positiivisesta palautteesta kohtaavat. Lisäksi tarkoituksena on selvittää, mistä asioista oppilaat saavat palautetta. Kiinnostuksen kohteena ovat myös palautteenantotavat sekä positiivisen palautteen määrä. Tutkimus on luonteeltaan laadullinen. Tutkimukseen osallistui yksi englanninopettaja ja neljä hänen oppilastaan alakoulusta sekä yksi englanninopettaja ja …

The Recovery of the Optimal Damping Constant by the MRF Damper

2009

In this paper was studied a method to analyze the recovering of optimal damping constant because of temperature increasing in a shock absorber. The increasing on temperature leads to decreasing that constant by mean dynamic viscosity such to modify the dynamic behavior of a 2DOF system built-up by sprung and unsprung mass. A MagnetoRheological damper was designed according with the desired optimal damping constant once fixed temperature design. It was seen that the increasing of temperature this constant is lost. As MagnetoRheological-Fluids allows us to increase the viscosity, we use a control signal by a state feedback of reduced order to create a such magnetic induction field to recover …

Beliefs about oral corrective feedback in an Argentinean EFL university classroom : their impact on a teacher’s classroom actions

2019

Beliefs about oral corrective feedback (OCF) are essential components in the EFL classroom, especially when learning the speaking skill since teachers have to strike a delicate balance between the provision of OCF without negatively affecting students’ emotions. During the last years, many scholars have devoted great attention to the influence of affective factors in the learning of foreign languages. Among these factors, beliefs held by teachers and students have proved to impact significantly on the processes of teaching and learning a foreign language. The aims of this paper are: to describe the beliefs held by an Argentinian EFL teacher about OCF and to describe how her beliefs might sh…

Approximation of heat equation and backward SDEs using random walk : convergence rates

2018

This thesis addresses questions related to approximation arising from the fields of stochastic analysis and partial differential equations. Theoretical results regarding convergence rates are obtained by using discretization schemes where the limiting process, the Brownian motion, is approximated by a simple discrete-time random walk. The rate of convergence is derived for a finite-difference approximation of the solution of a terminal value problem for the backward heat equation. This weak approximation result is proved for a terminal function which has bounded variation on compact sets. The sharpness of the according rate is achieved by applying some new results related to the first exit time …

Digital control circuitry for the p53 dynamics in cancer cell and apoptosis

2010

Abstract Experimental work and theoretical models deduce a “digital” response of the p53 transcription factor when genomic integrity is damaged. The mutual influence of p53 and its antagonist, the Mdm2 oncogene, is closed in a feedback. This paper proposes an aerospace-based architecture for translating the p53/Mdm2/DNA damage network into a digital circuitry in which the optimal control theory is applied for obtaining the requested dynamic evolutions of some considered cell species for repairing a DNA damage. The purpose of this paper is to demonstrate the usefulness of such digital circuitry design to detect and predict the cell species dynamics for shedding light on their inner and mutua…

Measurement of the average shape of longitudinal profiles of cosmic-ray air showers at the Pierre Auger Observatory

2019

The profile of the longitudinal development of showers produced by ultra-high energy cosmic rays carries information related to the interaction properties of the primary particles with atmospheric nuclei. In this work, we present the first measurement of the average shower profile in traversed atmospheric depth at the Pierre Auger Observatory. The shapes of profiles are well reproduced by the Gaisser-Hillas parametrization within the range studied, for E>10 17.8 eV .A detailed analysis of the systematic uncertainties is performed using ten years of data and a full detector simulation. The average shape is quantified using two variables related to the width and asymmetry of the profile, and …

Feedback and Communication in Active Hydrogel Spheres with pH Fronts: Facile Approaches to Grow Soft Hydrogel Structures

2021

Abstract Compartmentalized reaction networks regulating signal processing, communication and pattern formation are central to living systems. Towards achieving life‐like materials, we compartmentalized urea‐urease and more complex urea‐urease/ester‐esterase pH‐feedback reaction networks into hydrogel spheres and investigate how fuel‐driven pH fronts can be sent out from these spheres and regulated by internal reaction networks. Membrane characteristics are installed by covering urease spheres with responsive hydrogel shells. We then encapsulate the two networks (urea‐urease and ester‐esterase) separately into different hydrogel spheres to devise communication, pattern formation and attracti…

To feed back or to feed forward? : Students' experiences of and responses to feedback in a Finnish EFL classroom

2017

Good feedback is a powerful element in learning. Ultimately, however, the impact feedback has on learning depends on how the learner responds to that feedback. So far, foreign or second language studies on feedback have mainly concentrated on different methods of error correction, not on students’ responses to feedback in general. This study aims to find out what students thought of the feedback they had received in their EFL studies. Furthermore, the study seeks to discover students’ different responses to that feedback. The data was gathered using a web-based questionnaire filled out by 140 students. The students, aged 17–19, were all from a single Finnish upper secondary school. The data…

Cost optimal analysis of lighting retrofit scenarios in educational buildings in Italy

2017

Abstract The European Energy Performance of Buildings Directive (EPBD) recast proposes, a comparative methodology to calculate cost-optimal levels of minimum energy performance requirements for buildings. This paper presents a method able to select the best retrofit action for lighting system, selectively analysing the daylight conditions and applying the cost-optimal methodology for different scenarios proposed for two existing educational buildings located in Italy. With the aim to improve both energy efficient and visual comfort conditions, the retrofit scenarios include lighting solutions with different combinations. They consider the replacement of lamps with more efficient lighting so…
