Networked Analysis of a Teaching Unit for Primary School Symmetries in the Form of an E-Book
2021
In mathematics education, technology offers many opportunities to enrich curricular contents. Plane symmetries is a topic often skipped by primary teachers. However, it is important and may be worked in attractive ways in dynamic geometry software environments. In any regular classroom there are students with different levels of mathematical attainment, some needing easy tasks while others, particularly mathematically-gifted students, need challenging problems. We present a teaching unit for plane symmetries, adequate for upper primary school grades, implemented in a fully interactive electronic book, with most activities solved in GeoGebra apps. The book allows student to choose which itin…
Probabilistic Logic under Coherence: Complexity and Algorithms
2005
In previous work [V. Biazzo, A. Gilio, T. Lukasiewicz and G. Sanfilippo, Probabilistic logic under coherence, model-theoretic probabilistic logic, and default reasoning in System P, Journal of Applied Non-Classical Logics 12(2) (2002) 189---213.], we have explored the relationship between probabilistic reasoning under coherence and model-theoretic probabilistic reasoning. In particular, we have shown that the notions of g-coherence and of g-coherent entailment in probabilistic reasoning under coherence can be expressed by combining notions in model-theoretic probabilistic reasoning with concepts from default reasoning. In this paper, we continue this line of research. Based on the above sem…
Mètode multinivell per promoure la prosocialitat a l’escola: contribució a la formació en RSU
2019
espanolLa prosocialidad se refiere a las acciones socialmente beneficiosas, implicando conducta, emociones y razonamiento, y aqui se propone un metodo para llevar a cabo una intervencion en centros educativos para su promocion mediante una estrategia multinivel o cadena de favores. Antecedentes: aunque no existe un antecedente especifico del metodo propuesto, existen estudios acerca de la promocion de la prosocialidad en la escuela, centrados en la conducta, las emociones o los razonamientos, y el principal antecedente es el metodo de intervencion prosocial de Robert Roche (Escotorin y Roche, 2011; Roche, 1999, 1997; Romersi, Martinez-Fernandez y Roche, 2011), de la Universidad Autonoma de …
How do university students’ web search behavior, website characteristics, and the interaction of both influence students’ critical online reasoning?
2020
The Internet has become one of the main sources of information for university students’ learning. Since anyone can disseminate content online, however, the Internet is full of irrelevant, biased, or even false information. Thus, students’ ability to use online information in a critical-reflective manner is of crucial importance. In our study, we used a framework for the assessment of students’ critical online reasoning (COR) to measure university students’ ability to critically use information from online sources and to reason on contentious issues based on online information. In addition to analyzing students’ COR by evaluating their open-ended short answers, we also investigated the stude…
An empirical study of the understanding of formal propositions about sequences, with a focus on infinite limits
2018
International audience; In this paper, we analyze the answers of one group of high-school students and two groups of first-year University students to a questionnaire designed to test their level of recognition and understanding of the formal definition of the concept of infinite limit. Although this empirical study is ancillary to a larger project centred on didactic engineering, its analysis sheds light on the key issue of the logical prerequisites for the learning of the fundamental concepts of analysis. It also provides a new tool to investigate students' concept-image of limits, and assess the impact of teaching contexts and teaching paths.
Efectos de la formación académica y del género sobre las destrezas de razonamiento científico de los estudiantes de secundaria: un estudio piloto
2022
Resumen En este estudio se intenta determinar el nivel de las habilidades de razonamiento científico de los estudiantes de educación secundaria y analizar la influencia de la formación académica y del género sobre dichas habilidades. También se pretende conocer las habilidades que presentan mayor dificultad para estos estudiantes. Han participado 122 estudiantes españoles de cuatro niveles académicos diferentes entre 8º y 11º grado (edades entre 13 y 17 años) a los que se ha administrado el cuestionario de habilidades de razonamiento científico propuesto por Hanson (2016). De las puntuaciones obtenidas en el cuestionario y del ANOVA realizado puede concluirse que: a) el nivel medio de habil…
Consumers’ Willingness to Pay for Agri-Food Products Delivered with Electric Vehicles in the Short Supply Chains
2022
This study aims at investigating the consumers’ willingness to pay (WTP) for agri-food products delivered in the farmers markets with electric vehicles (EVs). The empirical analysis has been carried out by administering an online questionnaire to 273 consumers within a hypothetical context. A multiple price list has been provided in order to measure the price premium for 1 kg of oranges transported by EVs comparing with the ones transported by traditional vehicles. A Tobit regression model has been used for the data analysis in order to identify the most influential factors affecting the consumers’ WTP. Results suggest that consumers’ WTP is mainly influenced by environmental attitudes, kn…
La constitucionalidad del razonamiento inductivo
2011
RESUMENParte de las sentencias se basan en razonamientos inductivos, lo que implícitamente nos reconduce a la cuestión del problema de la probabilidad en sede judicial. El Tribunal Constitucional se ha enfrentado en numerosas ocasiones a la tesitura de confrontar la presunción de inocencia con el respeto a la autonomía de la valoración de la prueba por parte de los tribunales. Por ello, ha establecido una serie de requisitos que deben cumplir los razonamientos inductivos para que se consideren constitucionales. El problema que analizamos es que ese canon se basa en arcaísmos, frases hechas y lugares comunes, lo que genera mucha inseguridad en una temática tan susceptible de error, como es l…
Visual Strategies in Analogical Reasoning Development: A New Method for Classifying Scanpaths
2013
International audience; Development of analogical reasoning is often explained by general maturation of executive functions. A consequence of the involvement of executive functions would be that children and adults differ in the visual strategies they apply when solving analogical problems. Since visual strategies can be studied by means of eye-tracking, we compared the visual scanpaths of children and adults in three different analogical reasoning tasks. This comparison was done by means of a novel technique that combined a recently developed algorithm for computing a “distance” between any pair of scanpaths (Jarodzka, Holmqvist, & Nyström, 2010), multidimensional scaling (MDS), and a neur…
Professional vision in the classroom: Teachers’ knowledge-based reasoning explaining their visual focus of attention to students
2023
This study investigated Grade 2 teachers' (N = 50) professional vision through eye-tracking methodology and retrospective think-aloud interviews. The study examined the extent to which teachers' knowledge-based reasoning explains their visual focus of attention to whole class and individual students. We found that teachers' descriptions of students' social relations and emotions associated positively with teachers' visual focus of attention to the whole class. Teachers' descriptions of teacher-related information/elaboration and pedagogy linked negatively with teachers' visual focus of attention to individual students. The findings suggest that teachers' visual focus of attention to student…
