description: Quale importanza ha rivestito la rappresentazione grafica della frase semplice nella grammatica tradizionale? E la rappresentazione della frase complessa? È utile, una volta scelto un modello, rappresentarne graficamente i nodi fondanti e le relazioni che li legano? Quale impatto ha la visualizzazione degli schemi negli studenti, non solo della scuola primaria, ma anche in quelli della secondaria di primo e di secondo grado? La rappresentazione più nota e diffusa del modello valenziale è in grado di rispettare coerentemente la scientificità del modello e i rapporti gerarchici tra i costituenti, in particolare quelli della frase complessa? Queste sono sostanzialmente le domande che le autrici del contributo si sono poste e alle quali hanno cercato di dare risposta sulla base della loro esperienza didattica nella scuola secondaria di primo e secondo grado, dei numerosi corsi di formazione e dell’analisi della rappresentazione radiale finora più coerente con il modello valenziale. The graphic representation of the sentence and the period: a problem, an additional difficulty or an opportunity? What is the importance of the graphic representation of the simple phrase in traditional grammar? And the representation of the complex phrase? Is it useful, once a model has been chosen, to graphically represent its founding nodes and the relationships that bind them? What impact does the visualization of patterns have on students, not only in primary school, but also in middle and high school? Is the best known and most widespread representation of the valency model able to consistently respect the scientific nature of the model and the hierarchical relationships between the constituents, in particular those of the complex phrase? These are the questions that the authors have tried to answer on the basis of their didactic experience in middle and high schools, numerous training courses and the analysis of the radial representation that has been more coherent with the valency model up to now.

description: Posto che l’analisi valenziale di una frase è importante per capire il ruolo fondamentale in essa rivestito dal verbo, si ritiene opportuno abituare gli studenti della scuola secondaria di secondo grado ad osservare anche tutti i mezzi con cui si possono esprimere le relazioni concettuali tra processi. Le proposte di attività nascono dalla necessità di stimolare il ragionamento sulla lingua per evitare la semplificazione e l’abuso di un modello di analisi talora adottato in modo meccanico. Antidotes to mechanisms. Examples of activities for a grammar like training in critical thinking Since the analysis of the value of a sentence is important in order to understand the fundamental role played by the verb, it is considered appropriate to accustom secondary school students to observe how they can express the conceptual relationships between processes. The proposals for activities arise from the need to stimulate reasoning on language to avoid the simplification and abuse of a model of analysis that is sometimes adopted in a mechanical way.

NODI PROBLEMATICI NELLA GRAMMATICA VALENZIALE: LA SICUREZZA DEL METODO

description: Come è ormai ampiamente noto, il modello valenziale ipotizza che il verbo sia il centro propulsore della frase e ne determini la struttura. Per lavorare con questo modello, bisognerà quindi in prima battuta ragionare sul verbo, e imparare a individuare gli elementi necessari, gli argomenti indispensabili alla realizzazione dell’evento rappresentato dal verbo. In questo saggio, dopo aver discusso il concetto di obbligatorietà dell’argomento, si affrontano una serie di casi problematici, e si individuano sottogruppi di verbi la cui struttura argomentale non è immediatamente evidente, o (il che è il caso più frequente) di verbi che presentano più strutture argomentali, e quindi più significati. Infine si incoraggiano i docenti a non temere le difficoltà, e ad incentivare la discussione con gli allievi sui casi più controversi. Si tratta di ragionare non già in termini di giusto/sbagliato, ma di più o meno plausibile, più o meno convincente, tenendo nel debito conto da una parte l’età degli allievi, dall’altra le sistemazioni già disponibili in materia. Problematic nodes in valency grammar: the reliability of the method As it is now widely known, the valency model assumes that the verb is the propelling center of the sentence and determines its structure. In order to work with this model, it is therefore necessary to reason about the verb and learn how to identify necessary elements, indispensable argument for the realization of the event represented by the verb. In this essay, after discussing the concept of the compulsoriness of the argument, we deal with a series of problematic cases and identify subgroups of verbs whose argumentative structure is not immediately evident or (which is the most frequent case) verbs that have several argumentative structures and therefore more meanings. Finally, teachers are encouraged not to fear difficulties and encourage discussion with students on the most controversial cases. It is a question of reasoning, not in terms of right or wrong, but what is more or less plausible, more or less convincing, taking due account of the students’ age and the structures?? already available on the subject.

description: Excitons in van der Waals (vdW) stacking interfaces can be trapped in ordered moire potential arrays giving rise to attractive phenomenons of quantum optics and bosonic many-body effects. Compare to the prevalent transition metal dichalcogenides (TMDs) systems, due to the wide bandgap and low dielectric constant, excitons in twist-stacked hexagonal boron nitride (hBN) are anticipated trapped in deeper moire potential, which enhances the strength of interactions. However, constrained by the common low detectivity of weak light-emitting in the deep-ultraviolet (DUV) bands, the moire excitons in twisthBN remain elusive. Here, we report that a remarkable DUV emitting band (peak located at ~260 nm) only emerges at the twisted stacking area of hBN, which is performed by a high collection efficiency and spatially-resolved cathodoluminescence (CL) at room temperature. Significant peak redshifting contrast to defect-bound excitons of bulk hBN indicates the giant trapping effects of moiré potential for excitons. The observation of deeply trapped excitons motivates further studies of bosonic strongly correlation physics based on the twist-hBN system.

description: We consider the Dirac cones and higher-order topological phases in quasi-continuous media of classical waves (e.g., photonic and sonic crystals). Using sonic crystals as prototype examples, we revisit some of the known systems in the study of topological acoustics. We show the emergence of various Dirac cones and higher-order topological band gaps in the same motherboard by tuning the geometry of the system. We provide a pedagogical review of the underlying physics and methodology via the bulk-edge-corner correspondence, symmetry-based indicators, Wannier representations, filling anomaly, and fractional corner charges. In particular, the theory of the Dirac cones and the higher-order topology are put in the same framework. These examples and the underlying physics principles can be inspiring and useful in the future study of higher-order topological metamaterials.
Pulse induced resonance with angular dependent total enhancement of multi-dimensional solid-state NMR correlation spectra

description: We demonstrate a new resonance condition that obeys the relation $Δδ=nν_{R}/2$, where $Δδ$ is the chemical shift difference between two homonuclear-coupled spins, $ν_{R}$ is the magic-angle spinning speed and $n$ is an integer. This modulation on the rotational resonance recoupling condition is obtained by the application of rotor-synchronous $^{1}$H pulses when at least one proton is dipolar-coupled to one of the homonuclear-coupled spins. We suggest a new experimental scheme entitled "pulse induced resonance with angular dependent total enhancement" (PIRATE) that can enhance proton-driven spin diffusion by the application of a single $^{1}$H pulse every rotor period. Experimental evidence is demonstrated on the two carbon spins of glycine and on the Y21M mutant of fd bacteriophage virus. Numerical simulations reveal the existence of the resonances and report on the important interactions governing this phenomena.

description: We study the modular symmetric standard-model effective field theory. We employ the stringy Ansatz on coupling structure that 4-point couplings $y^{(4)}$ of matter fields are written by a product of 3-point couplings $y^{(3)}$ of matter fields, i.e., $y^{(4)} = y^{(3)}y^{(3)}$. In this framework, we discuss the flavor structure of bilinear fermion operators and 4-fermion operators, where the holomorphic and anti-holomorphic modular forms appear. From the Ansatz, the $A_4$ modular-invariant semileptonic four-fermion operator $[\,\bar E_R ΓE_R][\,\bar D_R ΓD_R\,]$ does not lead to the flavor changing (FC) processes since this operator would be constructed in terms of gauge couplings $g$ as $y^{(3)} \sim g$. The chirality flipped bilinear operator $[\,\bar D_R ΓD_L\,]$ also does not lead FC if the mediated mode corresponds to the Higgs boson $H_d$. In this case, the flavor structure of this operator is the exactly same as the mass matrix. On the other hand, if the flavor structure of the operator is not the exactly same as the mass matrix, the situation would change drastically. Then, we obtain the non-trivial relations of FC transitions at nearby fixed points $τ=i,\,ω\,, i\infty$, which are testable in the future. As an application, we discuss the relations of the lepton flavor violation processes $ μ\to eγ,\, τ\to μγ$ and $τ\to eγ$ at nearby $τ_e=i$, where the successful lepton mass matrix was obtained. We also study the flavor changing 4-quark operators in the $A_4$ modular symmetry of quarks. As a result, the minimal flavor violation could be realized by taking relevant specific parameter sets of order one.

description: Black holes are considered to be exceptional due to their time evolution and information processing. However, it was proposed recently that these properties are generic for objects, the so-called saturons, that attain the maximal entropy permitted by unitarity. In the present paper, we verify this connection within a renormalizable $SU(N)$ invariant theory. We show that the spectrum of the theory contains a tower of bubbles representing bound states of $SU(N)$ Goldstones. Despite the absence of gravity, a saturated bound state exhibits a striking correspondence with a black hole: Its entropy is given by the Bekenstein-Hawking formula; semi-classically, the bubble evaporates at a thermal rate with a temperature equal to its inverse radius; the information retrieval time is equal to Page's time. The correspondence goes through a trans-theoretic entity of Poincaré Goldstone. The black hole/saturon correspondence has important implications for black hole physics, both fundamental and observational.

description: In questo contributo si intende presentare il fascicolo A partire dalla frase. Sillabo di riflessione sulla lingua per la scuola primaria e secondaria di I grado, realizzato nell’ambito di un progetto di formazione, ricerca e sperimentazione da un gruppo di insegnanti di italiano delle scuole del primo ciclo della Provincia autonoma di Bolzano con la consulenza scientifica di M. G. Lo Duca. Si analizzano in particolare i punti di riferimento del lavoro svolto dal gruppo: lo studio su basi scientifiche aggiornate della lingua che si insegna a scuola; il confronto con gli esiti della ricerca sperimentale; l’individuazione di un modello teorico di descrizione della lingua coerente, potente ed economico e di un metodo euristico- attivo che favorisca una riflessione intelligente sui fenomeni linguistici. Partendo dalla storia del progetto La moderna ricerca grammaticale e le sue implicazioni in ambito didattico, all’interno del quale è stato elaborato il Sillabo, si approfondiscono i presupposti metodologici e teorici sottesi alla sua struttura e articolazione e le motivazioni della scelta di utilizzare l’approccio valenziale per l’analisi della frase. Si presentano inoltre le ricadute in ambito didattico e istituzionale prodotte dalla diffusione del Sillabo, della grammatica valenziale e degli esiti della recente ricerca in ambito grammaticale attraverso attività di formazione e aggiornamento.

In particular, the points of reference for work the carried out by the group are analyzed: a scientifically-based study of the language taught at school, comparison with the results from the experimental research, the identification of a theoretical model of description of language that is coherent, powerful and economical and an active, heuristic method that favours intelligent reflection on linguistic phenomena. Starting from the history of the project La moderna ricerca grammaticale e le sue implicazioni in ambito didattico, in which the Syllable was developed, the methodological and theoretical assumptions underlying its structure and its articulation are examined as well as the reasons for choosing to use the valency grammar for the analysis of the sentence. The educational and institutional effects of the diffusion of the Syllabus, the valency grammar and the results of the recent research in the field of grammar through training and updating activities are also presented.

This source is one of the highest-energy known gamma-ray sources, with emission extending past 200 TeV. Modeling suggests that the bulk of the TeV gamma-ray emission is leptonic in nature, driven by the energetic radio-faint pulsar PSR J1907+0602. Depending on what assumptions are included in the model, a hadronic component may also be allowed. Using the results of the modeling, we discuss implications for detection prospects by multi-messenger campaigns.

description: Sterile neutrinos with keV-scale masses are popular candidates for warm dark matter. In the most straightforward case they are produced via oscillations with active neutrinos. We introduce effective self-interactions of active neutrinos and investigate the effect on the parameter space of sterile neutrino mass and mixing. Our focus is on mixing with electron neutrinos, which is subject to constraints from several upcoming or running experiments like TRISTAN, ECHo, BeEST and HUNTER. Depending on the size of the self-interaction, the parameter space moves closer to, or further away from, the one testable by those future experiments. In particular, we show that phase 3 of the HUNTER experiment would test a larger amount of parameter space in the presence of self-interactions than without them. We also investigate the effect of the self-interactions on the free-streaming length of the sterile neutrino dark matter, which is important for structure formation observables.

description: Successful fertilisation is one of the key steps determining success of assisted conception. Various factors including sperm or oocyte pathology and environmental factors have a significant impact on fertilisation rates. This systematic review is aimed to evaluate the existing evidence about factors affecting fertilisation and strategies to improve fertilisation rates. A literature search was performed using Ovid MEDLINE ® (Jan 1950–April 2016), EMBASE (Jan 1950–April 2016), Ovid OLDMEDLINE ®, Pre-MEDLINE (Jan 1950–April 2016) and the Cochrane Library. Relevant key words were used to combine sets of results and a total 243 papers were screened. Only qualitative analysis was performed, as there was major heterogeneity in study design and methodology for quantitative synthesis. Factors affecting fertilisation were divided into sperm- and oocyte-related factors. The methods to improve fertilisation rates were grouped together based on the approach used to improve fertilisation rates. Optimising laboratory condition and procedural effects in techniques is associated with improved fertilisation rates. Various techniques are described to improve fertilisation rates including assisted oocyte activation, physiological intracytoplasmic sperm injection (PICSI) and intracytoplasmic morphologically selected sperm injection (IMSI). This review highlights the promising strategies under research to enhance fertilisation rates. Adequately powered multicentre randomised trials are required to evaluate these techniques before considering clinical application.

description: Topological electronic phases exist in a variety of naturally occurring materials but can also be created artificially. We used a cryogenic scanning tunneling microscope to create dimerized chains of identical quantum dots on a semiconductor surface and to demonstrate that these chains give rise to one-dimensional topological phases. The dots were assembled from charged adatoms, creating a confining potential with single-atom precision acting on electrons in surface states of the semiconductor. Quantum coupling between the dots leads to electronic states localized at the ends of the chains, as well as at deliberately created internal domain walls, in agreement with the predictions of the Su-Schrieffer-Heeger model. Scanning tunneling spectroscopy also reveals deviations from this well-established model manifested in an asymmetric level spectrum and energy shifts of the boundary states. The deviations arise because the dots are charged and hence lead to an onsite potential that varies along the chain. We show that this variation can be mitigated by electrostatic gating using auxiliary charged adatoms, enabling fine-tuning of the boundary states and control of their quantum superposition. The experimental data, which are complemented by theoretical modeling of the potential and the resulting eigenstates, reveal the important role of electrostatics in these engineered quantum structures.

description: Questo contributo vuole restituire una parte dei ragionamenti fatti insieme ai docenti della scuola primaria durante il laboratorio del corso di formazione C’è grammatica e grammatica. Ogni paragrafo è costruito attorno ad alcuni importanti interrogativi sorti durante le discussioni con i docenti: Perché bisogna dividere in sintagmi? Come visualizzare la frase con gli studenti? Come si stabilisce se una frase è minima? Che cosa fare con la grammatica tradizionale? In ogni sezione, abbiamo fatto prima chiarezza sui concetti di base implicati nella questione, problematizzando e restituendo una sintesi delle acquisizioni più solide della linguistica, e poi abbiamo illustrato le attività proposte ai corsisti. Il quadro che ne emerge è sicuramente denso, ma, come sottolineiamo nelle conclusioni, è importante per un docente padroneggiare nozioni che vanno al di là di quanto strettamente necessario per le lezioni, al fine di sollecitare il ragionamento degli studenti e procedere con loro, passo dopo passo, alla scoperta del funzionamento della lingua. Asking the right questions: some reflections on the valency grammar in primary school This contribution aims to give feedback to primary school teachers who participated in a PD workshop C’è grammatica e grammatica. Each section is based on important questions that arose during discussions with teachers: Why is it necessary to divide into syntagms? How to visualize the sentence with the students? How to determine if a sentence is minimal? What to do with traditional grammar? In each section, we first clarify the basic concepts raised by the question, problematizing and restoring a synthesis of the most solid acquisitions of linguistics, and then we illustrate activities proposed to the students. The picture that emerges is certainly dense, but, as stressed in the conclusions, it is important for teachers to master notions that go beyond what is strictly necessary for the lessons, in order to promote the reasoning of the students and proceed with them, step by step, to discover the functioning of the language.

description: We study quantum cosmology of the $2D$ Jackiw-Teitelboim (JT) gravity with $Λ>0$ and calculate the Hartle-Hawking (HH) wave function for this model in the minisuperspace framework. Our approach is guided by the observation that the JT dynamics can be mapped exactly onto that of the Kantowski-Sachs (KS) model describing a homogeneous universe with spatial sections of $S^1\times S^2$ topology. This allows us to establish a JT-KS correspondence between the wave functions of the models. We obtain the semiclassical Hartle-Hawking wave function by evaluating the path integral with appropriate boundary conditions and employing the methods of Picard-Lefschetz theory. The JT-KS connection formulas allow us to translate this result to JT gravity, define the HH wave function and obtain a probability distribution for the dilaton field.

The complex phrase from a perspective of valency grammar The article offers a critical review of the description of the complex phrase (or period) in Italian reference grammars, focusing on the importance of the distinction between nuclear (or complementary) phrases, (circumstantial) subordinate phrases and relative phrases (modifiers). It therefore offers a useful methodological framework to reflect on the school practice of period analysis and the new modes of reflection on complex structures suggested by valency grammar.

description: We theoretically show that strong mechanical quantum squeezing in a linear optomechanical system can be rapidly generated through the dynamical instability reached in the far red-detuned and ultrastrong coupling regime. We show that this mechanism, which harnesses unstable multimode quantum dynamics, is particularly suited to levitated optomechanics, and we argue for its feasibility for the case of a levitated nanoparticle coupled to a microcavity via coherent scattering. We predict that for sub-millimeter-sized cavities the particle motion, initially thermal and well above its ground state, becomes mechanically squeezed by tens of decibels on a microsecond timescale. Our results bring forth optical microcavities in the unresolved sideband regime as powerful mechanical squeezers for levitated nanoparticles, and hence as key tools for quantum-enhanced inertial and force sensing.

description: Elongation of the point spread function due to atmospheric dispersion becomes a severe problem for high resolution imaging instruments, if an atmospheric dispersion corrector is not present. In this work we report on a novel technique to measure this elongation, corrected or uncorrected, from imaging data. By employing a simple diffraction mask it is possible to magnify the chromatic elongation caused by the atmosphere and thus make it easier to measure. We discuss the theory and design of such a mask and report on two proof of concept observations using the 40 cm Gratama telescope at the University of Groningen. We evaluate the acquired images using a geometric approach, a forward modelling approach and from a direct measurement of the length of the point spread function. For the first two methods we report measurements consistent with atmospheric dispersion models to within 0.5 arcsec. Direct measurements of the elongation do not prove suitable for the characterisation of atmospheric dispersion. We conclude that the addition of this type of diffraction mask can be valuable for measurements of PSF elongation. This can enable high precision correction of atmospheric dispersion on future instruments.

description: Electro-optical transducers are utilized for upconvertion of radio frequency (RF) signals to the optical frequency domain to study the RF signals with optical tools. The transducers frequently impact on the RF system and introduce additional noise, including optical shot noise as well as quantum back action noise, limiting the measurement accuracy. In this paper we theoretically study a technique based on a high efficiency electro-optical phase modulation effect that allows back action evading detection of an RF field quadrature. The main idea of proposed method is independent homodyne detection of two (Stokes and anti-Stokes) optical modes. It allows subsequent postprocessing of the detected signals, which, in turn, results in a broadband back action evading measurement leading to the high sensitivity evaluation of the RF signals.

GRAMMATICA (PERCHÉ, QUANDO E COME) E PRATICA TESTUALE
Creators: name: Sabatini, Francesco

description: Il panorama di riferimento è quello della condizione comune di un discente che alla L1 (materna e della società circostante) affianca l’apprendimento di una L2. Il discorso è tuttavia svolto interamente nell’ambito della L1, nella convinzione che senza una padronanza d’uso e una cognizione riflessa dei meccanismi grammaticali e testuali perseguite e raggiunte in questo campo, l’apprendimento di una L2 non trova nel discente terreno adatto. Altro dato presupposto è quello di un percorso d’istruzione previsto di 10 anni (durata dell’obbligo) con esiti che rispondano alle esigenze imposte dalle civiltà complesse per la generalità degli individui. In relazione a tali premesse, si distinguono fortemente i tempi dell’alfabetizzazione (da curare intensivamente nell’istruzione primaria) dai tempi della conoscenza riflessa dei meccanismi grammaticali e dei processi testuali. Gli uni e gli altri da impostare, poi, sulla base dei MODELLI oggi considerati più scientifici e produttivi, e cioè, rispettivamente: della grammatica valenziale, che conduce alla migliore raffigurazione della frase, come entità del SISTEMA della lingua; del patto comunicativo tra emittente e ricevente, come fattore che regolamenta la forma dei diversi tipi di TESTO, destinati a un’interpretazione più rigida (se più aderenti alle forme del sistema) o più elastica (se variamente discosti da esse). Grammar (why, when and how) and textual practice The frame of reference is that of a learner who combines learning L2 with L1 (maternal and surrounding society). However, the discussion is carried out within the context of L1, because without mastery of use and knowledge reflected in the grammatical and textual mechanisms, L2 learning does not find the right terrain. Another prerequisite is a 10-year educational course (duration of obligatory schooling) with results that meet needs imposed by complex societies. In relation to these premises, the time for literacy (to be intensively treated in primary education) is strongly distinguished from the time for knowledge that reflects grammatical mechanisms and textual processes. They are both based on MODELS that today considered more scientific and productive, namely: valency grammar, which leads to the best representation of a sentence, as an entity of the SYSTEM of the language; as well as communication agreement between the issuer and the receiver, as a factor that regulates the shape of the different types of TEXTS intended for more rigid interpretation (if closer to the forms of the system) or more elastic (if different from them).

description: Serverless computing promises a scalable, reliable, and cost-effective solution for running data-intensive applications and workflows in the heterogeneous and limited-resource environment of the Edge-Cloud Continuum. However, building and running data-intensive serverless workflows also brings new challenges that can significantly degrade the application performance. Cold start remains one of the main challenges that impact the total function execution time. Further, since the serverless functions are not directly addressable, Serverless workflows need to rely on external (storage) services to pass the input data to the downstream functions. Empirical evidence from our experiments shows that the cold start and the function data passing take up the most time in the function execution lifecycle.
 In this paper, we introduce Truffle - a novel model and architecture that enables efficient inter-function data passing in the Edge-Cloud Continuum by introducing mechanisms that separate computation and I/O, allowing serverless functions to leverage the cold starts to their advantage. Truffle introduces Smart Data Prefetch (SDP) mechanism that abstracts the retrieval of input data for the serverless functions by triggering the data retrieval from the external storage during the function's startup. Truffle's Cold Start Pass (CSP) mechanism optimizes inter-function data passing and data exchange within serverless workflows in the Edge-Cloud Continuum by hooking into the functions' scheduling lifecycle to trigger early data passing during the function's cold start. Experimental results show that by leveraging the data prefetching and cold-start data passing, Truffle reduces the IO latency impact on the total function execution time by up to 77%, improving the function execution time by up to 46% compared to the state-of-the-art data passing approaches.

description: In this work, we present a general purpose deep neural network package for representing energies, forces, dipole moments, and polarizabilities of atomistic systems. This so-called recursively embedded atom neural network model takes both advantages of the physically inspired atomic descriptor based neural networks and the message-passing based neural networks. Implemented in the PyTorch framework, the training process is parallelized on both CPU and GPU with high efficiency and low memory, in which all hyperparameters can be optimized automatically. We demonstrate the state-of-the-art accuracy, high efficiency, scalability, and universality of this package by learning not only energies (with or without forces), but also dipole moment vectors and polarizability tensors, in various molecular, reactive, and periodic systems. An interface between a trained model and LAMMPs is provided for large scale molecular dynamics simulations. We hope that this open-source toolbox will allow future method development and applications of machine learned potential energy surfaces and quantum-chemical properties of molecules, reactions, and materials.
RIFLESSIONE SULLA LINGUA E MODELLO VALENZIALE: COMINCIAMO DALLA PRIMARIA?
Creators: name: Lo Duca, Maria G.
Publisher: name: Italiano LinguaDue

description: Il saggio parte dalla definizione delle due espressioni presenti nel titolo: “riflessione sulla lingua” e “modello valenziale”. Quanto alla prima, si sostiene che, nell’impostare un qualsiasi intervento di tipo grammaticale, sia opportuno partire non già da definizioni e liste precostituite, ma dalla naturale capacità di “riflettere sulla lingua” che tutti i bambini sviluppano spontaneamente nell’acquisire la loro lingua materna. Quanto al modello valenziale, dopo una breve presentazione dello stesso, ci si interroga se esso possa essere proposto già nella scuola primaria, e, sulla base di ricerche sul campo e di alcuni dati ricavati dalle prove nazionali di valutazione (Invalsi), si argomenta a favore di una presentazione precoce del modello, che alla prova dei fatti si rivela semplice e intuitivo, e consente di esercitare al meglio le capacità riflessive degli allievi. Reflection on language and the valency model: should we begin with the primary school? The essay starts by defining the two expressions present in the title: “reflection on language” and “valency model”. Regarding for the former, it is argued that in setting up any grammatical intervention, it is appropriate to start from the natural ability to “reflect on the language” that all children develop spontaneously in acquiring their mother tongue rather than from pre-established definitions and lists. As for the valency model, after a brief presentation, we consider whether it can be proposed in primary school and, based on field research and data obtained from national evaluation tests (Invalsi), we argues in favor of early presentation of the model, which is simple and intuitive and promoting the students’ best reflective skills.
