Phoneme processing skills are reflected in children's MMN responses.

2017

Phonological awareness (PA), the core contributor in phoneme processing abilities, has a link to later reading skills in children. However, the associations between PA and neural auditory discrimination are not clear. We used event-related potential (ERP) methodology and neuropsychological testing to monitor the neurocognitive basis of phonological awareness in typically developing children. We measured 5–6-year-old children's (N=70) phoneme processing, word completion and perceptual reasoning skills and compared their test results to their brain responses to phonemic changes, separately for each test. We found that children performing better in Phoneme processing test showed larger mismatc…

Assessing Online Collaborative Problem Solving Among School Children in Finland : A Case Study Using ATC21S TM in a National Context

2018

Online collaborative problem-solving tasks were piloted in five Finnish schools participating in the Assessment and Teaching of Twenty-first Century Skills (ATC21STM) project. Process stream data from online tasks were captured from 480 Finnish students who explored dyad problem spaces. The log file data were explored to identify indicative behaviours of collaborative problem solving (CPS), which were coded into a series of dichotomous indicators. The Rasch simple logistic model was used to analyse student performance across the social and cognitive dimensions of CPS. Analysis of the Finnish data indicated that the construct can be interpreted using a two-dimensional model, matching the fin…

Problem solving: competence for the enhancement of talents. A research with future primary school and kindergarten support teachers

2021

Education to achieve individual talent must become a priority in the educational process in order to contribute to the construction of a sustainable society. Training teachers to promote talent in students means guaranteeing each person the educational success and the achievement of their maximum potential. If problem solving becomes a tool for the enhancement of talent in the classroom, training in this competence becomes essential. In the educational field, talent and excellence are based on a unique attitude or an accentuated interest that a person possesses. The topic of the ability to solve educational problems by those who are going to carry out the profession of teacher implies the a…

Verifying a medical protocol with temporal graphs: the case of a nosocomial disease.

2014

Abstract Objective Our contribution focuses on the implementation of a formal verification approach for medical protocols with graphical temporal reasoning paths to facilitate the understanding of verification steps. Materials and methods Formal medical guideline specifications and background knowledge are represented through conceptual graphs, and reasoning is based on graph homomorphism. These materials explain the underlying principles or rationale that guide the functioning of verifications. Results An illustration of this proposal is made using a medical protocol defining guidelines for the monitoring and prevention of nosocomial infections. Such infections, which are acquired in the h…

Chess Thinking and Configural Concepts

2012

The purpose of this work is to connect chess and mathematics education. First, we introduce the idea of configural concepts in chess thinking and then we outline a scheme to show the phases of chess reasoning and how to apply this idea to some conflictual situations. We conclude this work proposing two research problems in introducing chess in mathematical classroom activities.

Search for standard model Higgs bosons produced in association with W bosons.

2007

We report on the results of a search for standard model Higgs bosons produced in association with W bosons from p-pbar collisions at root s = 1.96 TeV. The search uses a data sample corresponding to approximately 1 fb-1 of integrated luminosity. Events consistent with the W to l-nu and H to b-bbar signature are selected by triggering on a high-pT electron or muon candidate and tagging one or two of the jet candidates as having originated from b quarks. A neural network filter rejects a fraction of tagged charm and light flavor jets, increasing the b-jet purity in the sample and thereby reducing the background to Higgs boson production. We observe no excess l-nu-b-bbar production beyond the …

Why does placing the question before an arithmetic word problem improve performance. A situation model account.

2007

The aim of this paper is to investigate the controversial issue of the nature of the representation constructed by individuals to solve arithmetic word problems. More precisely, we consider the relevance of two different theories: the situation or mental model theory (Johnson-Laird, 1983; Reusser, 1989) and the schema theory (Kintsch & Greeno, 1985; Riley, Greeno, & Heller, 1983). Fourth-graders who differed in their mathematical skills were presented with problems that varied in difficulty and with the question either before or after the text. We obtained the classic effect of the position of the question, with better performance when the question was presented prior to the text. …

Esperienze con studenti italiani e cinesi: processi cognitivi e soluzioni di problemi matematici.

2011

Uno dei problemi più interessanti che si pongono oggi è certamente quello di confrontarsi con la “diversabilità” in situazioni di multicultura, realtà ormai presente nella nostra società, in continuo mutamento socio-culturale, e quindi nodo centrale per la ricerca in didattica della Matematica e non solo. Se infatti i fenomeni di insegnamento/apprendimento delle discipline hanno già sistemi complessi di indagine, la “diversabilità multiculturale” ne aumenta notevolmente la complessità. Ogni persona, appartenente ad una stessa cultura, possiede differenze cognitive rispetto ai suoi simili; in ambienti multiculturali queste si sommano a quelle riscontrabili nei diversi saperi che interagiscon…
