Students’ Conceptions of Assessment in Finnish EFL classrooms
2017
Kielitaidon arviointia on tutkittu paljon, mutta oppilaiden mielipiteitä arvioinnista on tutkittu huomattavasti vähemmän. Koska opettajien tekemä arviointi kuitenkin vaikuttaa eniten oppilaisiin, on tärkeä huomioida myös heidän mielipiteensä sekä kielten opetuksessa että kielitaidon arviointia tutkittaessa. Tämän tutkielman tarkoituksena oli selvittää, minkälaisia mielipiteitä lukiolaisilla on englannin kurssien arvioinnista. Tutkimuskysymykset koskivat muun muassa sitä, pitävätkö opiskelijat arviointia oppimista ja opetusta edistävänä vai turhana, arvioidaanko heitä heidän mielestään tarpeeksi ja keskittyykö arviointi liikaa ylioppilaskokeisiin. Tutkielman aineisto kerättiin kyselylomakkee…
An optimal dimensioning method of a green wall structure for noise pollution reduction
2021
International audience; This paper concern the optimization of a multilayered green wall structure including substrate and foliage in order to reduce as much as possible backward noise reflection and forward transmission from the wall. Each component involved in the wall structure is fully characterized experimentally to get its transfer matrix. Simulation demonstrated that foliage layer superimposed to substrate layer doesn’t affect the transmission losses but contributes greatly to the increase of return losses of the green wall structure. To achieve the best performances in terms of return and forward losses as well as frequency bandwidth, the methods of optimization are discussed inclu…
Analyse de l'activité de glaciéristes dans une perspective de conception de matériel de progression pour l'escalade et la montagne : contribution à l…
2015
The aim of the present thesis is twofold: first, it gives an overview onice climbers’ activity, based on an enactive empirical research program of cognitive anthropology, while developing a technological research program toevaluate appropriation situations and perspectives for design. The first part of this work focuses on the link between innovation and practice while identifying the relationship between the climbers and the technical object in order to build a technological research program focusing on the appropriation of objects. The second part is an epistemic work inculding two steps: a) to produce knowledge on the mediation role of ice axes for novice climbers and b) to develop desig…
Misconceptions of the p-value among Chilean and Italian academic psychologists
2016
Common misconceptions of p-values are based on certain beliefs and attributions about the significance of the results. Thus, they affect the professionals' decisions and jeopardize the quality of interventions and the accumulation of valid scientific knowledge. We conducted a survey on 164 academic psychologists (134 Italian, 30 Chilean) questioned on this topic. Our findings are consistent with previous research and suggest that some participants do not know how to correctly interpret p-values. The inverse probability fallacy presents the greatest comprehension problems, followed by the replication fallacy. These results highlight the importance of the statistical re-education of researche…
Génération de supercontinuum infrarouge et enjeux de vieillissement au sein de fibres optiques à coeur suspendu hautement non linéaires en verre de c…
2014
The work reported in this thesis deals with the fabrication of suspended core chalcogenide microstructured optical fibers (MOFs) for supercontinuum generation (SCG) beyond 6 μm. In this context, As2S3-based suspended-core MOFs were fabricated under vacuum, and loss threshold of 1-2 dB/m at 2.9µm were systematically registered. In addition, MOFs were designed with core diameter ranging from 1.5 to 3.5µm, allowing therefore to control the MOF's dispersive properties and to shift corresponding zero dispersion wavelength to 2.0-2.5 µm range. SCG experiments were performed by pumping the fabricated MOFs in their anomalous dispersion regime by means of tunable femtosecond laser source. Simultaneo…
Contribution to the development of 100% bio-based composites : synthesis of bio-based polyepoxides, supercritical CO2 treatment of hemp fibers and im…
2018
This thesis contributes to the development of 100% bio-based hemp/epoxy composites. Current environmental issues favor the emergence of materials derived from renewable resources such as plant fibres and a wide range of bio-based building-blocks, source of epoxy prepolymers in particular. An intensive investigation of the two constituents (hemp fibres and polyepoxidic matrix) is carried out before the composites manufacturing. Supercritical CO2 treatment is applied to hemp fibres used as reinforcement in composite materials. This treatment, not optimized, leads to better individualization as well as a decrease in the hygroscopic power of the fibres. These aspects, which are essential in ord…
Reproducibility and relative validity of a newly developed web-based food-frequency questionnaire for assessment of preconception diet
2019
Abstract Background The importance of diet and nutrition during preconception age is a window of opportunity to promote future parental and transgenerational health. As a sub-study to a large Norwegian study, ‘Diet today – health of tomorrow’, a food-frequency questionnaire (FFQ) was developed to assess diet during the preconception phase in young adults aged 20 – 30 years and in this paper we report the reproducibility and relative validity of this questionnaire. Methods The FFQ was developed from an existing FFQ validated in adolescents. Participants were recruited on social media and at a university. Reproducibility was assessed by comparing the test and retest of the FFQ. Relative valid…
Évolution des conceptions après une formation pédagogique
2008
08050 - Egalement disponible à l'adresse : http://www.aipu2008-montpellier.fr/index.php?dossier_nav=839; International audience; Depuis 2005, l'université de Bourgogne (France) offre à ses chargés de TD/TP (assistants) la possibilité de se former à leur métier d'enseignant via une formation pédagogique de 4 jours. Cette formation vise à les aider à se constituer un référentiel -tant pratique que théorique- afin de s'acquitter au mieux de leurs tâches d'enseignement. Elle a jusqu'à présent accueilli environ 80 jeunes enseignants issus de diverses disciplines. Nous avons souhaité mesurer les effets formatifs perçus par les apprenants. Pour ce faire, si l'on considère que l'apprentissage peut …
Template-Assembled Synthetic G-Quartets (TASQ) hydrosolubles : du ligand de quadruplexes d'ADN et d'ARN à la plateforme catalytique
2013
Natural G-quartets, a cyclic and coplanar array of four guanine residues held together via Hoogsteen H-bond network, have recently received much attention due to their involvement in G-quadruplex-DNA, an alternative higher-order DNA structure strongly suspected to play important roles in key cellular events (chromosomal stability, regulation of gene expression). Besides this, synthetic G-quartets, which artificially mimic native G-quartets, have also been widely studied for their involvement in nanotechnological applications (i.e. nanowires, artificial ion channels, etc.). In contrast, intramolecular synthetic G-quartets, also named template-assembled synthetic G-quartet (TASQ), have been m…
Incremental-Entity Personal Conceptions of Intelligence and Individualism-Collectivism in Italian Students
2015
This article examines the relationship between Incremental-Entity personal conceptions of intelligence and the cultural dimension of Individualism-Collectivism in Italian students attending high school. Four types of individualism and collectivism were investigated: 1) Vertical-Individualism, characterized by independent and different self; 2) Horizontal-Individualism, characterized by independent and similar self; 3) Vertical-Collectivism, characterized by interdependent and different self; and 4) Horizontal-Collectivism, characterized by interdependent and similar self. The sample includes 250 students,3th and 5th graders. A battery of tests including a Sociodemographic Questionnaire, the…
