Published: August 2022

The widespread adoption of smartphones and unmanned aerial vehicles (UAVs) has the potential to ease collection of in-season cotton nitrogen (N) status. Subsequently, in-season cotton N status could be used to drive management decisions. The utility and limitations of these new platforms must be assessed and compared to current in-season measurements. The objectives of this study were to evaluate the ability of early- and late-season ground-based measurements to provide insight into cotton N status and to evaluate the ability of aerial-based measurements to correlate to ground-based measurements. Although measurements failed to correlate strongly across seasons to leaf N, moderate relationships (R2 = 0.453) between chlorophyll meter readings and the dark green color index (DGCI) measured from a smartphone were observed in late-season measurements. Poor relationships were found between early-season UAV-acquired vegetation indices (VIs) and leaf N. Analysis of a subset of the data indicated relationships between chlorophyll meter readings and chlorophyll concentrations predicted by DGCI were strong for ground-based measurements and moderate for UAV-based measurements. (R2 = 0.711 and R2 = 0.511, respectively). Although additional site-years including aerial-based data are needed, this study demonstrates the usefulness of UAV-based reflectance data and VIs in predicting in-season cotton N status. Furthermore, it appears handheld DGCI measurements have the potential to replace chlorophyll meter readings for late in-season measurements of cotton N status.

Published: August 2022

In 2020, there were an abnormal number of seed coat fragment (SCF) reports from cotton produced in Alabama, Georgia, and Florida resulting in price deductions of more than $23 million in the region and $18 million in Georgia alone based on loan value. To understand what led to the historic number of SCF calls, variety trial samples from Georgia were evaluated for SCF issues. Trials were conducted across 24 locations in Georgia and included 12 varieties. A total of 286 seedcotton samples were ginned at the UGA Microgin in Tifton, GA, and two fiber samples were collected, one for High Volume Instrument and one for Advanced Fiber Information System (AFIS) analysis, and a seed sample was collected for free fatty acid (FFA) analysis. None of the samples sent to the Memphis, TN classing office received an extraneous matter call; however, there were differences in AFIS seed coat nep (SCN) counts, trash, and FFA when evaluated by site and variety. Variety was not as impactful as location, indicating that environmental differences between sites were responsible for the differences. As more rainfall occurred from first open boll to harvest, SCN count increased. Additionally, as average daily solar radiation increased, SCN count decreased. Therefore, it was determined that significant and prolonged weathering is what likely led to the outbreak of SCF issues in the Southeast. Future research should continue to evaluate environmental impacts on the occurrence of extraneous matter as well as an objective method to determine extraneous matter occurrences in cotton lint.

Published: August 2022

On spindle type cotton harvesters, spindles are attached to bars which are arranged on rotating drums. Opposed drum harvesting units position one drum on each side of the row, whereas harvesting units with an in-line drum arrangement position both drums on the right side of the plant row. Two studies conducted in Australia and the United States focused on comparing drum arrangements in regard to harvesting efficiency and fiber quality as there has been no recent published research using high yielding commercial varieties. These studies concluded that there were slight, but insignificant differences among opposed and in-line drum arrangements in terms of harvesting efficiency and lint turn out. Although only statistically significant for the work conducted in the US, lint ginned from seed cotton harvested by the opposed drum arrangement contained more trash than that harvested by the in-line arrangement. In both countries there were small insignificant differences in terms of fiber color (both Rd and +b), length, and micronaire, after ginning and lint cleaning. Although not observed in Australia, small significant differences in length uniformity and strength were observed in favor of the opposed drum arrangement in the US. Measured only in Australia, there were no significant differences between the two drum arrangements in terms of short fiber index, fineness, and maturity. There was also no significant difference between the two drum arrangements in terms of total, fibrous and seed-coat nep content, and size.
Efficacy of Burndown with Sequential Applications for Junglerice (Echinochloa colona) Control
Authors: Perkins Clay M. , Mueller Thomas C. , Steckel Lawrence E.
Published: August 2022

Junglerice has continued to expand its range as a serious weed pest in Tennessee cotton. Both glyphosate resistance and herbicide antagonism have been documented as possible causes for poor control. Approximately 15% of junglerice populations in Tennessee have been found to be glyphosate resistant. In addition, dicamba tank mixtures with glyphosate and/or clethodim have been reported to reduce junglerice control. Due to poor in-crop control, starting clean has taken on added importance when trying to control junglerice. Therefore, research was conducted to determine the best herbicide burndown methods utilizing clethodim, dicamba, glufosinate, glyphosate, or paraquat. Paraquat alone or in tank-mixtures with glyphosate or clethodim provided poor control (< 50%). Likewise, glufosinate alone or in tank-mixture with glyphosate or clethodim provided poor control (< 35%). A dicamba + glyphosate, glufosinate + clethodim, or paraquat + clethodim application provided poor junglerice control. Regardless of which herbicides were initially applied, making a follow-up application of glyphosate or glyphosate + clethodim two weeks later provided optimal control of junglerice. In Tennessee, a glyphosate + clethodim application at 14 days before planting is recommended to control junglerice, other grasses and some broadleaf weeds, followed by paraquat at-planting to control remaining weed species.
A Module Feeder Inspection System For Plastic Contamination – Updated System Design
Authors: Wanjura John D. , Pelletier Mathew G. , Holt Greg A.
Published: August 2022

This note describes the updated design and operation of an inspection system that provides ginners an instantaneous view of the dispersing cylinders in a cotton gin module feeder. Images are provided by network cameras installed in the back wall of a module feeder using a new adjustable housing design that allows for easier installation into various module feeder designs. We observed that when these systems are installed and operated, accumulation of plastic and other contaminants on dispersing cylinders is detected and removed more quickly than when the cylinders are manually checked between work shifts or during other pauses in gin operation. Gin crews are more responsive to plastic accumulation on the dispersing cylinders because they can see when it occurs and quickly remove the contaminants, thereby reducing the risk of plastic contamination in lint bales.

Harvest aids provide cotton farmers with the ability to harvest in an efficient and timely manner. Harvest aids also assistant in preserving overall fiber quality by reducing fiber degradation and discoloration from exposure to weather and by the reduction of foreign matter. Many harvest-aid active ingredients do not translocate within the plant, thus adequate spray coverage is recommended to improve efficacy of these products. The widespread and rapid adoption of auxin-tolerant cotton varieties has increased the use of larger droplet size nozzles that are required for use with auxin herbicides. Subsequently, the use of larger droplet size nozzles for harvest-aid applications will likely increase. The objective of this study was to determine the impact of droplet size and carrier volume on defoliation, desiccation, boll opening, terminal and basal regrowth, and cotton leaf grade. Varying water volumes of 47, 93, 140, and 187 L ha-1, and nozzles that produced fine, medium, and ultra-coarse droplets were evaluated at 14 site years across the Cotton Belt in 2016 and 2017. Numeric trends indicate higher carrier volumes are more successful at defoliating and opening bolls than lower carrier volumes. Water volumes of 47 L ha-1 should be avoided when making cotton harvest-aid applications, as all defoliation, open boll, and regrowth values were consistently reduced at the lowest carrier volume. Treatments of various nozzle types had less impact on harvest-aid efficacy than carrier volume. Site interactions with harvest aids had a greater effect than nozzle type or water volume.

Published: August 2022

Glufosinate is used widely to control glyphosate-resistant Palmer amaranth (Amaranthus palmeri S. Wats.) in cotton (Gossypium hirsutum L.). Previous research has shown weed control with several herbicides, including glufosinate, can be affected by application time of day. The response sometimes has been attributed to diurnal leaf movement (leaf orientation) in the weeds. The objectives of our research were to determine the influence of time of day of glufosinate application on Palmer amaranth control and to determine if the response was related to diurnal leaf orientation. Field experiments in five states evaluated Palmer amaranth control with glufosinate applied at nine intervals ranging from 1 h before sunrise to 6 h after sunrise and nine intervals ranging from 6 h before sunset to 1 h after sunset. Greatest Palmer amaranth control was achieved with glufosinate applied 2 h after sunrise to 1 h before sunset. Ammonium sulfate, added only to glufosinate 1 h before sunrise or 1 h after sunset treatments, did not improve control. Leaf angles of Palmer amaranth and velvetleaf (Abutilon theophrasti L.) were determined in a greenhouse at 1 h before light, 2 h after light, mid-day, 2 h before dark, and 1 h after dark. Leaves of velvetleaf oriented downward during the dark periods but time of day had no effect on leaf orientation of Palmer amaranth. These results demonstrate the need for sunlight for optimum glufosinate efficacy on Palmer amaranth.
Upland Cotton (Gossypium hirsutum L.) Fuzzy-Seed Counting by Image Analysis
Authors: Herritt Matthew T. , Jones Don C. , Thompson Alison L.
Published: August 2022

In recent years cottonseed size has been reduced as a result of the substantial fiber yield increases cotton breeders have made. Small cottonseed size has been associated with reduced germination, low seedling vigor and stand establishment, and has created production problems for downstream whole seed users. The potential loss in revenue to the cotton industry due to small seed size is substantial and has prompted a renewed effort by breeders to generate high-yielding, high-quality varieties with increased seed size. To aid these efforts and enable a better understanding of the effects of seed characteristics on fiber, a fuzzy-seed imaging method was developed. The method utilizes inexpensive, off-the-shelf equipment and an open source image processing pipeline to derive the number of seeds, seed index, and seed area, height, width, and perimeter. The time to image the seed and process the image takes less than three minutes per sample on average. The seed counts and seed index were strongly correlated with manual measurements at r = 0.967 and 0.693, respectively. Associations among seed characteristics and fiber indicate seed area, when used to calculate lint density, could be a useful selection criterion for breeders to increase both yield and seed size.
Polyvictimization in Sex-Trafficking Victims: A Conceptual Analysis of Psychosocial Consequences of Polyvictimization on Sex-Trafficked Victims
Authors: Jidung Kimsain , Mudra Gyan
Published: August 2022

To understand the web of violence as an interconnection to polyvictimization, it is significant to recognize how susceptibility to abuse is deeply rooted in the psychological, physical, and social context and can be linked to earlier victimization experiences, particularly for victims of trafficking. The current paper briefly examines the outcomes of sex trafficking on the psychological and biophysical health of victims by applying the framework of polyvictimization in assessing the trajectory of multiple forms of victimization that adds to the trauma of a sex trafficked victim before, during, and after trafficking. The paper provides an overview of the factors that influence the continuum of victimizations before and after trafficking. The paper also includes actionable measures in order to mitigate the factors of polyvictimization focused on improving the psychological and physical health of trafficked victims, which can serve as a basis for devising relevant recommendations to the policymakers and implementing agencies working closely with trafficked victims and survivors on how to mitigate the psychological and physical issues emerging out of the trafficking experience.

Diagnosing Boerhaave Syndrome in a 16-year-old girl in a primary care centre
Authors: Khan Javed , Muhid Abdul , Mushtaq Farah
Published: August 2022

Boerhaave syndrome is the spontaneous rupture of the oesophagus due to raised intra-oesophageal pressure and is a potentially fatal condition. The patient often presents with retrosternal chest pain and upper abdominal pain associated with significant history of retching and vomiting. The condition has a mortality rate of up to 40% hence early diagnosis and timely intervention is crucial. This emergency is rarely seen in children and young adolescents. We report a case of Boerhaave syndrome in a 16-year-old girl who presented to a primary care setting with vomiting, abdominal pain, and subcutaneous emphysema. The diagnosis of oesophageal rupture was made clinically. Thus, immediate referral to secondary care was vital in providing urgent management. This discussion highlights that this emergency can present in younger age adolescents, therefore high index of suspicion is imperative for good prognosis.

Vaccination against Influenza among Health Care Workers in Al Mashaer during Hajj 2019 (1440 H); Uptake and Barriers
Authors: Alqahtani Faris Maeed , Kamel Shady A. , Almudarra Sami , Mathkour Alaa A.
Published: August 2022

Background: Hajj (i.e., pilgrimage) is one of the largest mass gatherings in the globe. It brings people from around the world into small confined areas, which facilitates the transmission of droplet infections, like influenza. Saudi Arabia requires all healthcare workers (HCWs) receive the influenza vaccine since they can transmit influenza among infected patients to un-infected patients, including high-risk groups. We sought to assess the commitment of the HCWs toward vaccination as well as the reasons for vaccine refusal. Methodology: A cross-sectional study was performed during Hajj season 2019 among HCWs in Al Mashaer, Makkah, Saudi Arabia. Anonymous, self-administered questionnaires were distributed to collect the information on demographic characteristics, vaccine uptake, and their attitudes and concerns towards receiving the vaccine. Results: A total of 760 completed questionnaires were received, with a response rate of 95%. Males represented (58%), and the average age (Mean±SD) was 36.7±7.65 years. More than half of participants (56%) were working in the primary Health Centers (PHCs), while (44%) were working in the hospitals. (93%) of the participants have received the vaccine before in their life. For the 2019 Hajj season, (76%) of them received the vaccine. Following the authority’s recommendation (74%) was the main reason for vaccination, 24% were not vaccinated before attending this Hajj, and 25% did not intend to take the vaccine in the future. Concerns about the vaccine side effects (46%) and misconceptions regarding its efficacy (44%) were the main barriers for vaccination refusal. Logistic regression analysis showed that the other health cadres, pharmacists, and working in hospitals were independently associated with vaccine avoidance in the 2019 Hajj. While for the future intention to take the vaccine, working in the hospitals, HCWs from the northern region, other health cadres, nurses, and pharmacists were independently associated with vaccine rejection. Conclusion: Despite the good uptake of the vaccine, there are still misconceptions about the efficacy of the vaccine and concerns about its side effects. Awareness programs are required to address those concerns, especially for younger staff, pharmacists, and other cadres. Higher vaccine uptake among healthcare workers will impact the vaccination of the general population. Key Words: Pilgrimage, Seasonal influenza vaccine, healthcare workers, Saudi Arabia.

Un approccio ecologico-culturale per definire il Mobile Learning
Authors: Giuseppe De Simone
Published: August 2022

Al giorno d'oggi, il Mobile Learning è spesso considerato come un modo possibile per creare ambienti di apprendimento virtuali e offre molte opportunità per produrre e condividere contenuti multimediali e promuovere l'educazione a distanza. Inoltre, i progetti di formazione e le iniziative sulle tecnologie mobili stanno aumentando in tutto il mondo, quindi ciò dimostra che esiste un interesse diffuso in questa area di studio che va oltre il campo delle tecnologie di insegnamento della ricerca educativa. Tuttavia, il Mobile Learning  è ancora un fenomeno relativamente nuovo, e difficile da decifrare, a causa dell'aggiornamento “quotidiano” delle tecnologie digitali e di telecomunicazione che producono nuove caratteristiche e vantaggi per ogni utente. Questo lavoro cercherà di fornire una chiara definizione di Mobile Learning e una guida ragionata per definirla attraverso un approccio culturale-ecologico per evidenziare i suoi benefici e limiti nell'istruzione quotidiana sia formale che informale.

Monitoring innovation in education to improve education policies and outcomes in OECD countries
Authors: Stéphan Vincent-Lancrin
Published: August 2022

Developing the ability to measure innovation as well as its drivers and effects is a first step to refining innovation policies and understanding how innovation can be used to improve education. Developing metrics also aims to set the basis for cumulative work on educational innovation and innovation policy in education by providing countries with indicators that can be regularly updated over time. The paper shows how this could draw on existing efforts in other sectors than education, then presents a recent measurement attempt at the international level using existing international education databases (TIMSS, PIRLS and PISA). After defining innovation and presenting the methodology, the paper shows where process innovation lay in education in Italy and in OECD countries. The conclusion highlights the link between innovation and improvement and notes some of the limitations of the current approaches.

L’edilizia scolastica in Italia: Recensione al "Rapporto sull'Edilizia Scolastica" promosso dalla Fondazione Agnelli (Laterza, 2019)
Authors: Giovanni Biondi
Published: August 2022

Il Rapporto sull’edilizia scolastica curato dalla Fondazione Agnelli (Laterza, 2019) è la prima indagine prodotta in Italia su questo tema, dalla quale emerge l’inadeguatezza dei nostri edifici scolastici. I dati del rapporto rivelano che, deghli oltre 39.000 edifici scolastici presenti in Italia, solo il 7,2 % è dotato di una mensa, spazi sportivi e aula magna; il 40,6% ha soltanto spazi didattici (aule) e uffici amministrativi. Inoltre, 8.000 edifici sono stati costruiti per altri usi e adattati a scuola. Questi dati dimostrano come il modello «aule=scuola» sia ancora quello prevalente, e che siamo ancora ben lontani da un’idea di scuola come civic center.

Parola d’ordine STEM-conoscere per colmare il divario di genere. L'importanza del curricolo interdisciplinare di educazione finanziaria per promuovere il pensiero scientifico nella scuola primaria
Authors: Antonella Meccariello  , Renata Mentasti
Published: August 2022

L’articolo rientra nella categoria delle “reflection papers” in quanto rappresenta un contributo teorico di approfondimento sulle tematiche della pedagogia e curricula innovativi nell'educazione STEM nonché sugli approcci e le metodologie per la ricerca educativa STEM. Nel documento vengono messe in evidenza le problematiche legate alla didattica delle STEM, partendo dalle evidenze dell’ultima indagine dell’OCSE PISA che sottolinea fortemente l’attuale divario di genere nell’apprendimento delle discipline scientifiche, tecnologiche, ingegneristiche e matematiche. Tale differenza sembra condurre inevitabilmente ad una disuguaglianza sociale crescente, allontanando sempre di più i cittadini dal traguardo di sostenibilità individuato dall’Assemblea delle Nazioni Unite nella Risoluzione adottata nel 2015 e limitando fortemente l’indipendenza della popolazione femminile. Nell’articolo viene evidenziato che l’indagine summenzionata rivela una stretta correlazione tra l’alfabetizzazione matematica e quella finanziaria, tanto da indurre a considerare l’importanza dell’educazione precoce alle STEM anche attraverso percorsi didattici di educazione finanziaria nella scuola primaria, da inserire nei curricoli verticali degli istituti scolastici. Vengono suggerite alcune delle tematiche da affrontare con le diverse fasce d’età, le strategie educative da mettere in atto e le metodologie didattiche da utilizzare passando attraverso l’interdisciplinarietà e l’innovazione tecnologica. L’articolo si conclude con la convinzione che la scuola, non solo la famiglia, sia un contesto efficace per fornire ai giovanissimi gli strumenti di pensiero per sviluppare le competenze di problem solving e per effettuare scelte consapevoli ed informate.
Discipline STEAM e studenti Altamente Sensibili: Promuovere lo sviluppo di competenze trasversali e la valorizzazione delle differenze individuali nell'apprendimento.
Authors: Carlotta Pizzi
Published: August 2022

Le discipline STEAM rappresentano uno strumento didattico efficace per la promozione della parità, la valorizzazione delle differenze individuali come occasione di crescita collettiva e lo sviluppo di competenze trasversali che favoriscano la costruzione integrata della propria identità personale e professionale. In quest’ottica rappresentano un’opportunità di emersione e realizzazione per tutti quegli studenti Altamente Sensibili caratterizzati da una personalità introversa, e portatori di inclinazioni, necessità e potenzialità di cui la scuola deve necessariamente tenere conto per realizzare una didattica realmente inclusiva e costruttiva. Se posti nelle giuste condizioni, coi giusti strumenti e un corretto approccio metodologico basato sulla conoscenza e la consapevolezza del ruolo che genetica, ambiente ed esperienze formative giocano nella costruzione del Sé, questi studenti potranno acquisire consapevolezza nelle proprie capacità e avere l’opportunità di realizzarsi pienamente nel rispetto delle proprie caratteristiche individuali.

Il progetto XenoGRISS ha vinto il bando dell’Agenzia Spaziale Italiana (ASI) YiSS - Youth ISS Science 2019 ed è stato condotto sulla Stazione Spaziale Internazionale (ISS) dall’astronauta Luca Parmitano nel dicembre 2019 durante la missione "Beyond". XenoGRISS, che ha scopi sia scientifici che educativi, è stato progettato e presentato congiuntamente da ricercatori delle Università degli Studi di Milano e Firenze, da un gruppo di 9 studenti dell’ITIS A. Meucci di Firenze e da tre insegnanti dello stesso Istituto. Gli studenti sono stati coinvolti nello studio della crescita e della rigenerazione dei girini di Xenopus laevis in assenza di gravità e hanno affrontato sia gli aspetti scientifico-biologici dell'esperimento sia quelli tecnologici relativi all’hardware necessario al mantenimento dei girini per 30 giorni nello Spazio e alle rilevazioni scientifiche.

Published: August 2022

The present paper reports on work undertaken within the frame of the STE(A)M IT project on integrated STEM education (Erasmus + program; Grant agreement 612845-EPP-1-2019-1- BE-EPPKA3-PI-FORWARD). We will focus on a comprehensive review of grey and scientific literature published on integrated STEM and how this background desk research informed the development of an instrument designed to elicit stakeholder responses to core aspects of integrated STEM education. We have pilot tested the instrument to assess the validity and reliability of the scales it includes and we present the results of this pilot study together with some implications for educational policy and stakeholder involvement.
Recuperare la Dimensione Estetica dell’Educazione alle STEM
Authors: Maria Xanthoudaki  , Matteo Villa  , Fabrizio Stavola  , Patrizia Cerutti  , Stefano Buratti
Published: August 2022

L’articolo propone una riflessione metodologica sull’educazione alle STEM che pone l’attenzione su alcuni elementi che possano rappresentare un’innovazione del modo in cui si concepisce l’apprendimento in questo ambito. Lo fa attraverso l’analisi di Future Inventors, un progetto del Museo Nazionale della Scienza e della Tecnologia Leonardo da Vinci, che aspira a creare un nuovo approccio all’educazione alle STEM trasferibile nella pratica scolastica. La riflessione pone attenzione particolare sull’esperienza estetica – qui intesa come una chiave di lettura del mondo che considera come inseparabili l’esperienza cognitiva e quella affettiva; integra la costruzione del sapere con l’apprezzamento della bellezza e della forza delle idee; e attiva un processo trasformativo attraverso cui comprendiamo meglio le cose e noi stessi – in un tentativo di riposizionarla al suo posto primario nel processo di un apprendimento nelle STEM più interdisciplinare ed ecologico.
Didattica innovativa e valutazione tramite portfolio digitale nel contesto universitario: il punto di vista degli studenti
Authors: Daniela Torti
Published: August 2022

Questo contributo presenta una ricerca qualitativa volta a esplorare l’opinione di 35 studenti rispetto alla frequenza del corso universitario di psicologia e scuola. Il corso, basato sulla prospettiva socioculturale, proponeva una metodologia didattica innovativa con valutazione degli studenti tramite portfolio digitale. Tale modalità offriva una didattica efficace basata su una rappresentazione interattiva del processo di insegnamento/apprendimento, volta alla produzione di acquisizioni significative per lo studente e alla costruzione di abilità trasversali. Dai dati emersi, si evince l’importanza dell’introduzione nei percorsi formativi universitari di attività autentiche che richiamino la collaborazione tra studenti. Inoltre, appare importante diffondere nuovi approcci valutativi, al fine di incoraggiare una modalità di apprendimento autodeterminata.
XXI secolo e 4K. Formare i docenti per raccogliere la sfida delle competenze al tempo del digitale: l’esempio del docente di tedesco
Authors: Sabrina Bertollo
Published: August 2022

4K è il nome con cui le competenze descritte dal Framework for 21st century learning – Comunicazione, Cooperazione, Creatività e Pensiero Critico – sono note nel mondo germanofono, ma è anche sinonimo di innovazione tecnologica e di progresso. Il presente contributo si configura come una riflessione sulle potenzialità offerte dall’integrazione delle competenze del XXI secolo nella formazione dei docenti e nella didattica disciplinare attraverso l’esempio del docente di tedesco. Si evidenzierà come lo sviluppo di ciascuna di queste competenze possa essere concretamente e utilmente integrato nella didattica della lingua tedesca, a partire da una formazione dell’insegnante di natura esperienziale che valorizzi le potenzialità offerte dal digitale e dai nuovi ambienti di apprendimento.
Presenza, Partecipazione e Progresso con gli altri nella Didattica a Distanza
Authors: Marianna Piccioli
Published: August 2022

Anche nella Didattica a Distanza ci aspettiamo che sia mantenuta la qualità di un intervento che possa chiamarsi didattico e che le proposte delle scuole, divenute virtuali, siano rivolte al raggiungimento di obiettivi collegialmente definiti. Nella realtà, però, le modalità di fare scuola con la DaD risultano molto eterogenee e probabilmente relegano in secondo piano una peculiarità che da più di quarant’anni caratterizza l’insegnamento nel nostro Paese: l’integrazione/inclusione degli alunni con disabilità. Cercare di comprendere quali livelli di inclusività possiamo riscontrare nell’azione educativa condotta attraverso la DaD è lo scopo di questo contributo, che intende rintracciare la contemporanea presenza di tre indicatori come la Presenza, la Partecipazione e il Progresso con gli altri nelle recenti esperienze di DaD.

Il contributo suggerisce strade sperimentate in ambito letterario e linguistico in ambienti digitali (pocasting, e-book, webmastering), propone strumenti utili e strategie per sviluppare nei ragazzi più motivazione, creatività e autonomia e per aiutarli a diventare cittadini digitali più consapevoli.
L’apprendimento collaborativo nei percorsi universitari online: dalla conoscenza alla competenza nello sviluppo della professionalità
Authors: Sara Mori  , Giuseppe Baldi
Published: August 2022

All’interno delle università, la didattica collaborativa non ha ancora trovato uno spazio coerente con quello che a essa viene dedicato dalla ricerca pedagogica, la quale tende a evidenziarne i benefici, in termini di apprendimento e di motivazione degli studenti. In questo articolo, viene illustrato il contesto metodologico e gli obiettivi di una ricerca sull’apprendimento sociale e collaborativo, svolta nell’ambito di due insegnamenti dell’Università Telematica degli Studi IUL e vengono presentati i risultati relativamente ai questionari iniziale e finale di un insegnamento. Viene confermato l’alto gradimento, da parte degli studenti, di questa modalità, pur nel riconoscimento di un impegno maggiore richiesto rispetto allo studio individuale e l’efficacia sia in termini di motivazione che di apprendimento.
La centralità del corpo in azione nei processi comunicativi, emotivi e apprenditivi, nell’ambito della comunicazione aumentativa e alternativa (CAA) nella scuola dell’infanzia
Authors: Gilda Cecoro
Published: August 2022

L’uso di strategie di comunicazione aumentativa e alternativa può avere rilevanti implicazioni in ambito educativo. Il bambino, attraverso l’uso del corpo e del simbolo, può scoprire occasioni di condivisione di pensieri ed emozioni, inedite chiavi di accesso all’apprendimento e originali forme di armonia emotiva con il gruppo dei pari e il docente. Dal punto di vista aumentativo, la CAA valorizza il patrimonio corporeo del soggetto non verbale (o con limitate capacità comunicative) e riconosce l’importanza di attribuire significato all’insieme dei segnali corporei, che hanno un’influenza sul partner comunicativo. La dimensione cinestesica, in un percorso didattico-educativo centrato sulla CAA, costituisce la base per la manifestazione di forme intelligenti della persona (Gardner et al., 1987).
