Elucidating the Influence of the Activation Energy on Reaction Rates by Simulations Based on a Simple Particle Model
2020
An application for visualizing the dynamic properties of an equimolar binary mixture of isotropic reactive particles is presented. By introducing a user selectable choice for the activation energy, the application is useful to demonstrate qualitatively that the reaction rate depends on the above choice and on temperature. The application is based on a 2D realistic dynamic model where atoms move because of their thermal energies and the trajectories are determined by solving numerically Newton’s laws according to a Molecular Dynamics (MD) scheme. Collisions are monitored as time progresses, and every time the collision energy is larger than the selected activation energy, a reactive event oc…
Self-Reported Non-Celiac Wheat Sensitivity in High School Students: Demographic and Clinical Characteristics
2017
Background: Non-Celiac Wheat Sensitivity (NCWS) has recently been included among the gluten-related disorders. As no biomarkers of this disease exist, its frequency has been estimated based on self-reported symptoms, but to date no data are available about self-reported NCWS in teenagers. Aim: To explore the prevalence of self-reported NCWS in a group of high school students and to study their demographic and clinical characteristics. Methods: The study was performed between April 2015 and January 2016 in two high schools of a coastal town in the south of Sicily (Italy). A total of 555 students (mean age 17 years, 191 male, 364 female) completed a modified validated questionnaire for self-r…
The socio-ecological and personal determinants of school performance and motivation of high school students
2022
For decades, and with the work of Moos (1979) and Walberg (1969), educational research has consistently demonstrated the importance of the personal characteristics of students and the socio-ecological characteristics of the classroom in determining the affective and cognitive development of students.Unfortunately, no research on this subject has been done in France with high school students. This is why we set ourselves the objective of studying the environmental and personal determinants of high school students' academic performance and motivation. Using the L.E.I (Walberg, 1969) and EMMAS (Ntamakiliro et al., 2000) measurement scales, as well as data collection from 405 students enrolled …
Realistic Implementation of the Particle Model for the Visualization of Nanoparticle Precipitation and Growth
2019
An application for visualizing the aggregation of structureless atoms is presented. The application allows us to demonstrate on a qualitative basis, as well as by quantitatively monitoring the aggregate surface/volume ratio, that the enhanced reactivity of nanoparticles can be connected with their large specific surface. It is suggested that, along with the use of geometric analogies, this bottom-up approach can be effective in discussing the enhanced reactivity proprieties of nanoparticles. The application is based on a two-dimensional realistic dynamic model where atoms move because of their thermal and interaction potential energies, and the trajectories are determined by solving numeric…
Ethnicity and Educational Inequality: An investigation of School Experience in Australia and France. Ethnicité et inégalité scolaire : une enquête su…
2008
This thesis examines the contribution of ‘ethnic' background to the school experiences of educationally and socially disadvantaged students in the senior years of high school (n=927). To investigate the role both of ethnic identification and its interplay with institutional factors, a comparative analysis of secondary student experiences in two national settings was undertaken. The case of Turkish-background students in Australia and France suggests that the influences of ethnic identity are thoroughly transformed from one setting to the other by distinctive pedagogical structures. Streaming and severe academic judgement in France lower academic self-esteem, while creating resentment and so…
Impact of Sport-related Games on High School Students' Communication Skills
2015
Abstract In Recent studies underline the fact that adolescents are, at many times, likely to experience serious communication problems with their families and close environments. So, the aim of this study is to determine positive impact of sport-related games, which are performed as extracurricular activities, on high school students’ communication skills. In the study, pre, & post-tests was utilized with the control group’s experimental patterns. Two participant groups were made up of totally 30 high school students, 15 of whom would be in the experimental group and the rest of whom were in the control group. The former group was given sport- related 20 applications for 10 weeks during…
La valoración del Practicum en la formación inicial: un estudio de casos internacional en el área de Geografía e Historia
2020
El acceso a la función docente es asunto regulado por las instituciones administrativas, pero depende en gran medida de las competencias, actitudes y expectativas personales. Los estudios comparativos que mostramos revelan que las representaciones sociales que determinan un sentido práctico del saber escolar inciden en las opiniones de los actuales profesores de Secundaria y en los que aspiran a serlo. Este fenómeno subjetivo, que incide en las competencias profesionales, se interpreta cualitativamente con una metodología de casos, con la comparación de estos a partir de las encuestas y memorias del Practicum en tres universidades de Brasil, Colombia y España. El análisis sobre objetivos y …
The effect of polytechnic reform on migration
2011
This paper examines the effect of the polytechnic reform on geographical mobility. A polytechnic, higher education reform took place in Finland in the 1990s. It gradually transformed former vocational colleges into polytechnics and also brought higher education to regions that did not have a university before. This expansion of higher education provides exogenous variation in the regional supply of higher education. The reform raised the mobility of high school graduates across local labour markets in the years after they had completed their secondary studies, which indicated increased mobility between high school and post-secondary education. We estimate that the reform enhanced the annual…
La transición española : ¿qué sabe el alumnado de 1º de bachillerato?
2020
El presente artículo es el resultado del análisis de una encuesta realizada a 79 estudiantes de 1º de Bachillerato sobre la transición española. Mediante esta investigación se quiere acreditar, con metodología cuantitativa, los conocimientos e ideas que el alumnado encuestado tiene acerca de ese periodo histórico tras la realización de la Educación Secundaria. Para ello se ha realizado una encuesta con variedad de preguntas entre las cuales se han incluido algunas relacionadas entre sí para comprobar posibles contradicciones en las respuestas. La encuesta abarca diferentes cuestiones: desde personajes históricos hasta actores más globales como diferentes organizaciones o movilizaciones soci…
Urban Orienteering Competitions – A Unique Activity of Didactic Communication
2014
Abstract The aim of our project was to deepen understanding of the legacy of our predecessors, which are to be found in the historical centre of Sibiu, to develop map reading skills using the techniques and rules of orienteering. Most students participated enthusiastically in the search for historical sights and found the activity extremely attractive. Moreover, both the preparation stage, when the students learnt all together or in groups how to use a map in order to locate the historical sights, and the follow-up stage, when they disseminated the results, contributed to developing team spirit and a sense of belonging. Communication among students and with the form teacher also improved an…
