Pythagoras on the rocks. A proof with bricks
Creators: name: Cagol, Michele

Year: 2016

description: In this short paper a practical and simple proof of the Pythagorean theorem is proposed. It uses colourful interlocking plastic bricks with two shapes: a cube that measures two centimeters on each side and a right prism where the base is a right-angled isosceles triangle and the two equal rectangular faces are the same as those of the cubic brick. The proof is designed for primary school children (but also for preschool children) and begins by telling the legend of Pythagoras, who discovered his theorem by looking at the floor tile pattern of Polycrates’ palace. This proof takes into account only right-angled isosceles triangle but it is possible to show the validity of Pythagorean theorem for all right-angled triangles by building a simple proof by rearrangement. Pitagora on the rocks. Una dimostrazione con i mattoncini In questo breve contributo viene proposta una semplice dimostrazione pratica del teorema di Pitagora, utilizzando mattoncini a incastro di plastica colorata di due forme: un cubo di due centimetri per lato e un prisma retto la cui base è un triangolo isoscele rettangolo e nel quale le due facce equivalenti sono uguali a quelle del mattoncino cubico. La dimostrazione è rivolta a bambini della scuola primaria (ma, eventualmente, anche in età prescolare) e prende le mosse dalla leggenda secondo la quale Pitagora avrebbe scoperto il suo teorema mentre stava osservando il pavimento piastrellato del palazzo di Policrate, tiranno di Samo. Da questa dimostrazione – che prende in considerazione solo triangoli rettangoli isosceli – è poi possibile passare a una dimostrazione del teorema di Pitagora per tutti i triangoli rettangoli.

description: Chronic wounds require suitable treatment and management strategies for proper healing. Among other causes, infection delays the healing of wounds and increases the risk of wound-related complications. In this study, an inherently antibacterial and biocompatible wound dressing is developed to enhance the healing. Chemical modification of a natural polysaccharide, Isabgol with epoxypropyltrimethylammonium chloride, renders antibacterial activity to the material. This is the first report of such chemical modification of this polymer for biomedical applications. The modified material is freeze-dried to obtain porous scaffolds. 13C NMR and FTIR analysis confirmed the modification of the Isabgol polymer chains with EPTMAC. SEM analysis confirmed the porous structure of the scaffold that would allow the exchange of gases and nutrients through the matrix. The material can swell up to 17 times its initial weight, allowing it to absorb wound exudates and maintain a moist environment at the wound site. Thermogravimetric analysis and compression testing showed that the scaffold has suitable thermal and mechanical properties. The material is antibacterial and can potentially prevent infections at the wound site. In vitro studies have confirmed that these scaffolds are cytocompatible and hemocompatible. These properties indicate that the EPTMAC-modified Isabgol scaffolds would be suitable for wound dressing applications.

Year: 2016

description: Outlined are guidelines (teaching/learning sequences) for chemistry teachers in the first two years of secondary school. This educational proposal is grounded on an inquiry-based approach, and follows the spiral structure of the different levels of the chemistry concepts (from macroscopic to microscopic). Our aim is both the assessment of a more significant learning process and the achievement of some students’ basic skills, as well as to provide teachers with a tool for implementation in class. The examples illustrated refer to the sequences relative to chemical transformation and the particle model. In closing, the results of a study are exhibited, which support the effectiveness of the proposed approach on the basis of the results obtained by the students. Progettazione di sequenze didattiche di insegnamento/apprendimento della chimica secondo un approccio inquiry-based Viene illustrata la progettazione di linee guida (sequenze didattiche di insegnamento/apprendimento) per gli insegnanti di chimica nel primo biennio della scuola secondaria di secondo grado. Questa proposta didattica è concepita secondo un approccio inquiry-based, e segue la struttura a spirale dei diversi livelli di concettualizzazione della chimica (dal macroscopico al microscopico). Scopo del progetto è, da un lato, il miglioramento della significatività dell’apprendimento degli allievi e il raggiungimento di alcune competenze trasversali di base, dall’altro, fornire agli insegnanti uno strumento da utilizzare nella pratica di classe per implementare la trasposizione didattica della disciplina. Gli esempi illustrati riguardano le sequenze relative alla trasformazione chimica e al modello particellare. Vengono infine mostrati i risultati di uno studio che supporta l’efficacia dell’approccio proposto sulla base dei risultati conseguiti dagli allievi.

Learning geometry and visuo-spatial abilities through coding
Creators: name: Sabatini, Martina
Publisher: name: Form@re - Open Journal per la formazione in rete
Year: 2016

description: This paper deals with the theme of coding, focusing particularly on its introduction in a specific primary school curriculum. The work presents the PhD research project “Learning geometry and visuo-spatial abilities through coding”. The project, which is not yet concluded, aims to reflect on the possibility of introducing coding activities within the primary school curricula of geometry of third graders, in order to study if and how these activities affect learning geometry and visuo-spatial abilities. To do so, the processes of teaching and learning of experimental classes (those in which coding activities take place) and control classes (those in which coding activities do not take place) will be compared, both in terms of quantity and quality. The classes has been chosen according to a uniformity requirement with respect to the starting points of geometrical knowledge and visuo-spatial abilities. L’apprendimento di conoscenze geometriche e abilità visuo-spaziali attraverso il coding Il presente lavoro affronta la tematica del coding focalizzandosi in particolar modo sulla sua introduzione in uno specifico curricolo di scuola primaria. Viene presentato il progetto di ricerca di dottorato “L’apprendimento di conoscenze geometriche e abilità visuo-spaziali attraverso il coding”. Il progetto, non ancora concluso, intende riflettere sulla possibilità di introdurre attività di coding all’interno dei curricoli di geometria delle classi terze di scuola primaria, al fine di studiare se e come questo tipo di attività influisca sull’acquisizione di apprendimenti geometrici e abilità visuo-spaziali. Per farlo, verranno confrontati, sia in termini quantitativi che qualitativi, i processi di insegnamento-apprendimento di classi sperimentali (quelle in cui avvengono attività di coding) e di classi di controllo (quelle in cui non avvengono attività di coding). Le classi sono state scelte secondo un criterio di omogeneità relativamente alle situazioni di partenza delle conoscenze geometriche e abilità visuo-spaziali.

description: In this paper a didactical method that has been proven effective for evaluating the “resistance to the treatment” of the student is presented. This parameter is essential for distinguishing the learning difficulties in mathematics from the learning disorder of dyscalculia. The method is based on GimmeFive, an application that has been designed to develop skills in mental calculation of multi-digit additions and subtractions. In this paper we present the results of two experiments conducted with groups of students respectively with learning difficulties in mathematics and dyscalculia. These experiments allowed to show the effectiveness of the didactical method in the evaluation of the resistance to the treatment and to discuss the features that make it adequate for the evaluation of the learning disorder. An educational method for evaluating the resistance to the treatment in the diagnosis of dyscalculia In questo lavoro viene presentato un metodo didattico che si è dimostrato efficace per valutare la resistenza al trattamento dello studente che è uno dei parametri fondamentali per distinguere la difficoltà di apprendimento in matematica dal disturbo di apprendimento noto come discalculia. Il metodo si basa sull’uso dell’applicazione GimmeFive che è stata progettata per sviluppare competenze nel calcolo mentale di addizioni e sottrazioni a più cifre. In questo lavoro vengono presentati risultati di due sperimentazioni condotte con gruppi di studenti rispettivamente con difficoltà di apprendimento e con diagnosi di discalculia. Queste sperimentazioni hanno consentito di mostrare l’efficacia del metodo didattico nella valutazione della resistenza al trattamento e di discutere le caratteristiche che lo rendono adeguato per la valutazione del disturbo di apprendimento.

description: This paper shows how the analysis of items of Italian national standardized mathematics tests (Invalsi) can become a means to develop teacher education programs for mathematics middle school teachers. Through the comparison among peers and the teacher educator, the teachers can develop new lenses to look at the Invalsi mathematics tests using interpretative tools from research in mathematics education. In particular, in the educational activities that will be described, the teachers share a structured approach in the development of an a priori analysis of mathematics problems that takes into account institutional, epistemological, cognitive, and didactic aspects. These educational activities foster the development and sharing of knowledge and skills that can be identified as specialized knowledge for teaching. Un’attività di formazione per insegnanti di scuola secondaria di primo grado: analisi di prove Invalsi di matematica Questo articolo mostra come l’analisi di quesiti delle prove Invalsi di matematica possa diventare un mezzo per sviluppare attività di formazione per insegnanti di matematica di scuola secondaria di primo grado. Attraverso il confronto tra pari e con il docente formatore, gli insegnanti possono acquisire nuove chiavi di lettura delle prove Invalsi di matematica facendo propri alcuni strumenti interpretativi e di analisi provenienti dalla ricerca in didattica della matematica. In particolare, nelle attività di formazione che saranno descritte, gli insegnanti condividono un approccio strutturato nello sviluppo di un’analisi a priori di quesiti di matematica che tiene conto dell’intreccio di aspetti istituzionali, epistemologici, cognitivi e didattici. Queste attività di formazione hanno favorito lo sviluppo e la condivisione di conoscenze e abilità che possono essere identificate come conoscenze specialistiche per l’insegnamento.

description: This paper presents the state-of-the-art in relation to the certification of achievements for the first cycle of schooling. By considering the changes in legislation, organization and teaching methodology that have taken place in recent years throughout Primary and Lower Secondary School, the importance that the certification of achievements has today within the educational practice of schools is analyzed. Considering the theoretical and methodological perspective of the authentic assessment, this paper investigates to what extent the dialogue between educational research and school practice can offer suggestions to improve teaching with a view to successful learning, paying particular attention to how individual and citizenship competences can be developed and certified in the first cycle of schooling. L’uso delle rubriche valutative per la certificazione delle competenze: il modello Va.R.C.Co. Il presente contributo intende presentare lo stato dell’arte della certificazione delle competenze nella scuola del primo ciclo d’istruzione. Ripercorrendo i cambiamenti normativi, organizzativi e didattici che, negli ultimi anni hanno attraversato la scuola primaria e quella secondaria di primo grado, viene condotto un bilancio sull’importanza che oggi la certificazione delle competenze ricopre all’interno della prassi educativa delle scuole. A partire dalla prospettiva teorica e metodologica dell’authentic assessment, si indaga in che misura il dialogo tra ricerca educativa e pratica scolastica possa fornire elementi propositivi per il miglioramento della didattica nella prospettiva del successo formativo, ponendo un’attenzione particolare a come le competenze di base e di cittadinanza possono essere sviluppate e certificate nel primo ciclo d’istruzione.

The teaching of measurement from epistemology to computational thinking
Creators: name: Piccione, Andrea
Publisher: name: Form@re - Open Journal per la formazione in rete
Year: 2016

description: In this work the concept of measurement and the physical quantities were chosen to develop an inclusive didactical practice, which is based on the contemporary epistemological research and the rigor of international standards, and therefore cognitively demanding. This approach, together with the support of methods coming from the computer programming, supported the creation of a path that is widely accessible by students, as well as a correct definition of measurement. Through an appropriate didactical transposition the tools here described can be useful to raise the level of the educational practices in the classroom, e.g. to promote computational thinking. La didattica della misura dall’epistemologia al pensiero computazionale In questo lavoro sono stati scelti la misura e le grandezze fisiche come nucleo fondante intorno ai quali sviluppare una attività didattica inclusiva e al tempo stesso esigente dal punto cognitivo, perché basata sulla ricerca epistemologica contemporanea e sul rigore degli standard internazionali. Tale impostazione, unitamente al supporto di metodologie provenienti dalla programmazione informatica, ha consentito lo sviluppo di un percorso che presenta sia un’ampia accessibilità da parte degli studenti, sia una corretta definizione del concetto di misura. Attraverso questo ripensamento dei contenuti, le risorse proposte possono diventare strumenti per elevare il livello dell’offerta didattica e valorizzare le eccellenze, anche attraverso la promozione del pensiero computazionale.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We explore the dark matter and collider phenomenology of the minimal gauged $U(1)_B$ model, consisting of a leptophobic $Z_B$ gauge boson, and an accompanying Higgs $S_B$. By requirement of anomaly cancellation, the fermion sector naturally contains a dark matter candidate---a Majorana isosinglet $χ$ stabilized by an inherent $Z_2$ symmetry. The absence of evidence for $Z$ prime dijet resonances at the LHC suggests that the scale of symmetry breaking $Λ_{B}\gtrsim 500$ GeV. Saturation of dark matter abundance together with limits on the direct detection cross section (dominated by Higgs exchange) constrains the Higgs mixing angle to $|θ|\lesssim 0.22$. For small mixing angles of $|θ| \lesssim 10^{-3}$, the $\mathcal{O}(10\%)$ branching fractions of the fermion loop-mediated $S_B\rightarrowγγ$, $Zγ$, $ZZ$ modes may provide clues about the fermion content of the model at the LHC.

description: Bone drilling is a universal surgical procedure commonly used for internal fracture fixation, implant placement, or reconstructive surgery in orthopedics and dentistry. The increased temperature during such treatment increases the risk of thermal penetration of the bone, which may delay healing or compromise the fixation's integrity. Thus, avoiding penetration during bone drilling is critical to ensuring the implant's stability, which needs surgical drills with an optimized design. Bovine femur and mandible bones are chosen as the work material since human bones are not available and are the closest animal bone to human bone in terms of properties. In the present study, the Taguchi fractional factorial approach was used to determine the best design of surgical drills by comparing the drilling properties (i.e., signal-to-noise ratio and temperature rise). The control factors (spindle speed, drill bit diameter, drill site depth, and their levels) were arranged in an L9 orthogonal array. Drilling experiments were done using nine experimental drills with three repetitions. The findings of this study indicate that the ideal values of the surgical drill's three parameters combination (S1D1Di2) and their percentage contribution depend on the parameters' drilling levels. However, the result shows that the spindle speed has the highest temperature effect among other parameters in both (femur and mandible) bones.

description: The paper presents an in-service science teachers training project where digital videos are used to improve teaching practices, as recommended by educational research and international reports. In particular, we intend to illustrate a number of designed and implemented video formats, identifying them on the basis of their use in relation to the educational purposes. The latest format presented, to some extent similar to a web documentary, wants to represent a novelty in the Italian panorama of the in-service teacher training. Starting from a validated learning model in the field of educational research, its aim is to give an account of a truly authentic and exemplar practice. It wants to give a narrative form to the complexity and multidimensionality of the teaching practice, explaining not only the related issue, but also the teacher know how, the teacher-student dynamics and the strategies and technologies used. Come narrare una pratica didattica: dal video-esperimento al web documentario per migliorare l’insegnamento delle scienze Il contributo presenta un progetto di formazione in servizio dei docenti di scienze entro cui è stato fatto un uso del video funzionale al cambiamento delle pratiche di insegnamento, così come auspicato dalla ricerca didattica e dai rapporti internazionali. In particolare, si intendono illustrare i format video progettati e implementati, identificandoli sulla base del diverso uso che ne viene fatto in funzione degli obiettivi formativi. L’ultimo format che viene presentato, assimilabile per alcuni aspetti al web documentario, intende rappresentare una novità nel panorama italiano della formazione in servizio. Partendo da un modello di apprendimento validato nell’ambito della ricerca didattica, esso è pensato per narrare una pratica autentica ed esemplare, mantenendone complessità e multidimensionalità e dando conto non solo dei contenuti disciplinari trattati, ma anche dell’organizzazione dell’apprendimento, delle dinamiche docente-studente, delle strategie e delle tecnologie usate.

PotenziaMente 2.0. Developing numeracy in primary schools through computer games
Creators: name: Trinchero, Roberto
Publisher: name: Form@re - Open Journal per la formazione in rete
Year: 2016

description: Research in neuroscience and psychology of learning suggests the existence of inborn “number sense”, localized in specialized brain structures that deal with interpreting the world in terms of numbers. However in the common sense of young people and adults are still strong beliefs that mathematics is something of abstract, difficult and far away from everyday life. How is it possible to build numeracy in children using these innate capacities and fostering the development of the right attitudes towards the mathematical knowledge? The article describes the possible impact on educational practices of the research about the number sense and the role of executive functions in mathematical reasoning. It presents the basic principles of a collection of computer games freely available online (PotenziaMente 2.0) designed specifically to develop lexical, semantic and syntactic aspects of numeracy and increasing the use of executive functions in typical mathematical problem solving for primary school. PotenziaMente 2.0. Costruire la numeracy nella scuola primaria attraverso il gioco computerizzato La ricerca in neuroscienze ed in psicologia dell’apprendimento suggerisce già da tempo l’esistenza di un “senso del numero” innato, localizzato in strutture cerebrali specializzate che si occupano di interpretare il mondo in termini numerici. Eppure nel senso comune di giovani e adulti permangono credenze che vedono la matematica come un qualcosa di astratto, difficile e lontano dalla vita quotidiana. Come è possibile costruire la numeracy nei bambini sfruttando queste capacità innate e favorendo lo sviluppo dei giusti atteggiamenti verso il sapere matematico? L’articolo descrive le possibili ricadute educative della ricerca sul senso del numero e sul ruolo delle funzioni esecutive nel ragionamento matematico. Partendo da queste risultanze, presenta poi i principi alla base di una collezione di giochi computerizzati liberamente fruibili online (PotenziaMente 2.0) concepiti per sviluppare gli aspetti lessicali, semantici e sintattici della numeracy e potenziare l’uso delle funzioni esecutive su problemi matematici tipici della scuola primaria.

description: This paper illustrates the main teaching practices features in the Italian primary and secondary school, by using new data, provided by Invalsi, about teachers’ daily activities. We merge such information with the scores achieved by the students in the Invalsi test. Our study reframes the cognitive test results in mathematics from a new bottom-up perspective, that is internal to the educational system. La didattica della matematica e gli apprendimenti: un contributo a partire dai dati Invalsi La finalità principale del presente lavoro è di illustrare alcune caratteristiche delle pratiche didattiche del primo e del secondo ciclo di istruzione, utilizzando alcuni nuovi dati forniti da Invalsi sulle attività quotidiane degli insegnanti. Unendo queste informazioni con i punteggi ottenuti dagli studenti nel test Invalsi, si vogliono approfondire i risultati ottenuti dagli studenti in matematica partendo da una nuova prospettiva, interna al sistema di educazione.

description: The scientific approach to understand the nature of consciousness revolves around the study of human brain. Neurobiological studies that compare the nervous system of different species have accorded highest place to the humans on account of various factors that include a highly developed cortical area comprising of approximately 100 billion neurons, that are intrinsically connected to form a highly complex network. Quantum theories of consciousness are based on mathematical abstraction and Penrose-Hameroff Orch-OR Theory is one of the most promising ones. Inspired by Penrose-Hameroff Orch-OR Theory, Behrman et. al. (Behrman, 2006) have simulated a quantum Hopfield neural network with the structure of a microtubule. They have used an extremely simplified model of the tubulin dimers with each dimer represented simply as a qubit, a single quantum two-state system. The extension of this model to n-dimensional quantum states, or n-qudits presented in this work holds considerable promise for even higher mathematical abstraction in modelling consciousness systems.

description: Tests on B − L symmetry breaking models are important probes to search for new physics. One proposed model with ΔðB − LÞ ¼ 2 involves the oscillations of a neutron to an antineutron. In this paper, a new limit on this process is derived for the data acquired from all three operational phases of the Sudbury Neutrino Observatory experiment. The search concentrated on oscillations occurring within the deuteron, and 23 events were observed against a background expectation of 30.5 events. These translated to a lower limit on the nuclear lifetime of 1.48 × 1031 yr at 90% C.L. when no restriction was placed on the signal likelihood space (unbounded). Alternatively, a lower limit on the nuclear lifetime was found to be 1.18 × 1031 yr at 90% C.L. when the signal was forced into a positive likelihood space (bounded). Values for the free oscillation time derived from various models are also provided in this article. This is the first search for neutron-antineutron oscillation with the deuteron as a target.

description: Surface plasmon polaritons (SPPs) are coherent electromagnetic surface waves trapped on an insulator-conductor interface. The SPPs decay exponentially along the propagation due to conductor losses, restricting the SPPs propagation length to few microns. Gain materials can be used to counterbalance the aforementioned losses. We provide an exact expression for the gain, in terms of the optical properties of the interface, for which the losses are eliminated. In addition, we show that systems characterized by lossless SPP propagation are related to PT symmetric systems. Furthermore, we derive an analytical critical value of the gain describing a phase transition between lossless and prohibited SPPs propagation. The regime of the aforementioned propagation can be directed by the optical properties of the system under scrutiny. Finally, we perform COMSOL simulations verifying the theoretical findings.

description: Today in Italy 20-25% of students in primary school is reported to have difficulties with mathematical skills, although several researchers have noticed a man’s natural predisposition towards numbers. In the light of this high number of reports becomes therefore necessary to reconsider the didactic context to better support the natural evolution of numerical and mathematical cognition from early childhood. The following article presents the analogical method developed by Camillo Bortolato: non-conceptual didactic path focused on semantic process, subitizing and mental math. Apprendere al volo con il metodo analogico Ad oggi in Italia il 20-25% degli alunni nella scuola primaria viene segnalato per difficoltà nel calcolo, nonostante diversi ricercatori abbiano evidenziato una naturale predisposizione dell’uomo verso la numerosità. Alla luce di questo elevato numero di segnalazioni diviene necessario ripensare il contesto didattico per sostenere al meglio e fin dalla prima infanzia la naturale evoluzione della cognizione numerica e di calcolo. Nel seguente articolo viene presentato il metodo analogico di Camillo Bortolato, un percorso didattico non concettuale attento ai processi semantici, al ruolo del subitizing e del calcolo a mente.

description: Technological introduction into school takes place in the form of innovations that maintaining low awareness and memories of the previous phases. The work recalls briefly the main institutional initiatives and best-known theories of reference in order to foster a historical-critical awareness of what the experience may have informed us. In the last part we focus on references in vogue, such as coding and robotics, wondering if they are really innovations and if they are based on valid educational criteria. L’innovazione tecnologica nella scuola italiana. Per un’analisi critica e storica L’introduzione tecnologica nella scuola è caratterizzata da ondate che si succedono conservando scarsa consapevolezza e ricordo della fase precedente. Il lavoro ripercorre in modo sintetico le principali iniziative istituzionali e le più note teorie di riferimento che le hanno accompagnate nell’ottica di favorire una consapevolezza storico-critica su ciò che l’esperienza ci può aver insegnato. Nell’ultima parte ci si sofferma su riferimenti oggi in voga, quali il coding e la robotica, chiedendoci se siano davvero nuovi e se poggino su criteri pedagogici fondati.

description: Software Defined Networks have opened the door to statistical and AI-based techniques to improve efficiency of networking. Especially to ensure a certain Quality of Service (QoS) for specific applications by routing packets with awareness on content nature (VoIP, video, files, etc.) and its needs (latency, bandwidth, etc.) to use efficiently resources of a network. Predicting various Key Performance Indicators (KPIs) at any level may handle such problems while preserving network bandwidth. The question addressed in this work is the design of efficient and low-cost algorithms for KPI prediction, implementable at the local level. We focus on end-to-end latency prediction, for which we illustrate our approaches and results on a public dataset from the recent international challenge on GNN [1]. We propose several low complexity, locally implementable approaches, achieving significantly lower wall time both for training and inference, with marginally worse prediction accuracy compared to state-of-the-art global GNN solutions.
