Applied Plasticity Methods for Design of the Concrete Substructure at Mersey Gateway Bridge
Authors: Pedersen Nikolaj Rask , Ravn Uffe Graaskov , Brennan Gerard
Published: February 2021

The state of development of FE-programs in practical design of reinforced concrete structures has not yet advanced to such a level that the design and verification of concrete bridges can be carried out solely on the basis of FE-programs. For this reason the approach viaduct substructure of the Mersey Gateway Bridge located in Northwest England was designed by applying plasticity methods, which yielded a cost-effective and intuitive design. The methods which included both lower bound and upper bound solutions, were found to be an effective design tool and resulted in both simple and economical reinforcement designs. This paper presents how these methods have been applied within the Eurocode 2 framework.
Lightweight Concrete Bridges: Recent Data Reveal New Opportunities
Authors: Castrodale Reid Wilson
Published: February 2021

Recent tests and production experience reveal that structural lightweight concrete made with lightweight aggregates manufactured in the USA has potential benefits for the design and construction of bridges. Lightweight aggregates and their properties are briefly introduced; then engineering properties of lightweight concrete made with these aggregates are presented using recent data. Material properties discussed include density, design compressive strength (up to 70 MPa), tensile strength (approximately equal to strengths expected for normal weight concrete), modulus of elasticity, creep and shrinkage (comparable to normal weight concrete), durability (including both reduced permeability and cracking tendency), ductility, and thermal properties (possibly beneficial for mass concrete). Several bridges that used lightweight concrete are highlighted, showing that the material provides an economical and durable solution for bridges.

Published: February 2021

A heavy lifting operation was performed to build a concrete cut & cover tunnel underneath an ancient XVII- th arch stone bridge, Trujillo Bridge, at Lima, Peru. Two piers, 3000 tons each, were temporary shored by

300 mm diameter piles. Thirty seven 400 tons synchronized hydraulic cylinders worked together compensating the piers settlements, limiting the movement during the whole operation between -5 mm and + 2 mm, with no perceptible damage to the historical bridge. Six prestressed galleries per pier were manually excavated through the pier foundations to bridge the loads to the hydraulic devices supporting beam. Due to the high seismic hazard (0.53g PGA for 1000 years return period), a temporary earthquake resisting system has been installed throughout the whole construction process.

Authors: Lei Jun-Qing , Guo Dong-Chen , Meng Nan
Published: February 2021

The risk assessment has been studied for bridge Construction, in order to reduce the occurrence probability of the accident and ensure the personnel and structural safety. The hierarchical decomposes method has been used in the project to decompose the construction phase of each part and to identify the basic risk sources; by the way of letter inquiry to consult experts for analysing and estimating the risk; according to risk probability and risk level assignment to determine risk value; the risk list has been ultimately formed. We must consider the acceptable level of risk; the decision-makers can make optimal decisions using the theoretical achievement. The risk assessment used in the continuous prestressed concrete beam bridge construction phase has given good results and gained high appraisal.

Authors: Nilforoush Rasoul , Elfgren Lennart , Nilsson Martin
Published: February 2021

The aim of this study is to provide a numerical model which can realistically present the failure load and failure mechanism of pullout loaded anchor bolts (headed studs) in reinforced concrete structures. The numerical analysis is carried out through a three-dimensional finite element (FE) code based on the Microplane constitutive law. The intension is to calibrate the FE model and to verify the numerical results against available test results. The calibrated FE model is intended to be used for an ongoing study to evaluate the influence of member thickness, surface reinforcement and size of anchor head on the tensile capacity and performance of anchor bolts.

The simulation results showed very good agreements with the available test results. The objectivity of numerical modelling in respect to the size of finite elements as well as the defined boundary conditions was confirmed by additional numerical analyses.

Published: February 2021

This paper presents a comparative analysis of the results obtained for the test of compressive strength, through a program of interlaboratory tests on hardened concrete, the Company developed Carlos Campos Consultoria e Construções Ltda., in the School of Civil Engineering Federal University of Goiás and in the Department of Technical Support and Control of Furnas Centrais Elétricas S.A., located in Goiânia-Goiás, to identify and evaluate the influence of some factors involved in test compressive strength. For this, we sought to verify the result of compressive strength, the influence of the type of processor (A and B) and upload speed (0.3 and

0.6 MPa/s) body-of-proof cylindrical size 150 mm x 300 mm in the concrete class C30. It was concluded that the type of laboratory significantly affect the results of compressive strength. Furthermore, it is noteworthy that the body-of-evidence dimension 150 mm x 300 mm concrete class C30, tested with a loading speed of the testing machine of 0.3 MPa/s presented the results to the larger dispersions.

Authors: Lee Hohsing , Cordoba Eric
Published: February 2021

The San Francisco County Transportation Authority retained AECOM for the design of the new westbound ramps providing access between the new east-span of San Francisco-Oakland Bay Bridge and Yerba Buena Island. The purpose of the project is to improve mobility, safety, and access by replacing two westbound existing ramps on I-80 constructed in the 1930s. The new ramps will provide a significant improvement geometrically and operationally over the current ramps, and will include bridge structures that complement the SFOBB architecture. The project was cleared under an EIR/EIS prepared by AECOM. The construction contract of the project was awarded in late 2013, and construction completion is targeted for late 2016. This paper discusses a number of innovative design solutions to address the project challenges associated with the site conditions, environmental restrictions, geotechnical challenges, and a high level of seismicity.

Published: February 2021

The Parallel Structure (or ‘parallelstructuur’ in Dutch) for the A12 motorway near Gouda in the Netherlands is designed to relieve the weaving traffic on the A12/A20 interchange by creating a direct connection to bypass the interchange. The project consists of two components. The first component is the Extra Gouwe Crossing parallel to the A12 between the Gouda and Gouda-West off-ramps. The other component is the Moordrechtboog which will connect the A12 and A20 motorways. In the Extra Gouwe Crossing there will be a movable bridge to cross the river Gouwe. The bridge will be a balanced bascule bridge, with a total weight of 900 metric tons. The total length is 41 m and the width is 23,5 m. The span between main center of rotation and it’s front supports is 30 m. This paper is about the design challenges of this movable bridge.
The A82 Pulpit Rock Improvements – A Complex Propped Cantilever Viaduct
Authors: Patel Jaime , Stroscio Riccardo , Casewell Andrew
Published: February 2021

The A82 is a primary route in Scotland that follows the shore line of Loch Lomond. Following a landslide in the late 1970’s near the Scheduled Monument, Pulpit Rock, traffic lights were implemented limiting vehicles to one-way operation. A widening scheme was required to provide a two-way carriageway over a length of approximately 400m. This included a new six span 168m viaduct curved in plan to follow the existing road alignment and running parallel to the loch shoreline. The deck consists of a continuous open trapezoidal steel-concrete composite box girder supported on large diameter intermediate monopile piers socketed into the rock beneath. The construction was phased to minimise road closures. Partial construction of the deck facilitated switching of traffic to the new structure, allowing the remainder of the structure to be completed. This case study paper summarises the design and construction challenges of the viaduct.
Lilla Lidingöbron: Guidelines for design
Authors: Harris Simon , Knight Martin , Werner Jan
Published: February 2021

The ‘little Lidingö Bridge’ will be an important replacement crossing linking the island of Lidingö to the Stockholm mainland. Carrying both tram and pedestrian/cycle traffic, the new bridge will cross the open water of the Värtan strait in close proximity to a high level highway bridge. Knight Architects has worked with Lidingö Stad in the production of a set of pre-tender design guidelines that will inform and instruct the tenderer as part of the Design and Build procurement route. During the development of these guidelines; two crucial challenges to the success of the scheme became apparent: The formation of a harmonious visual relationship to the nearby highway bridge and to mitigate the potentially monotonous 750m length of the crossing to pedestrians with high quality ‘human friendly’ design.
Expansion joints and bearings for the largest lift bridge in Europa
Authors: Redecker Holger

Expansion joints and bearings for the largest lift bridge in Europa
Rotterdam has the largest lift bridge in Europe: the Botlekbrug. Opening and closing a bridge of this size represents uncharted territory. It requires special bearings and expansion joints which MAURER has developed specifically for this purpose. These can be opened and closed.

The new Botlekbrug is part of a 37 km motorway section of the A 15 that passes through Rotterdam port and is being widened by order of the Rijkswaterstaat.

Botlekbrug consists of two directly adjacent lift bridges.

The bridges do not open up completely – that would no longer be feasible with these dimensions. They move up to 40 m upwards.

A MAURER DS 720 swivel joist expansion joint is installed on the external passage of each bridge, while a MAURER DS 320 swivel joist expansion joint is installed on the internal passage.

The swivel joist is suspended from the steel superstructure and moves upwards with the bridge.

However, in order to ensure that it doesn´t fall down, the new expansion joints have extra lifting beams as a second special feature along with the standard cross beams. These lifting beams are twice as long as the cross beams, must not be rigid and have to be integrated – a group of requirements that significantly compresses and complicates the steel constuction.

Also a Challenge was moving the bridge downwards, expecially if it had been open for an extended period of time and had changed as a result of the heat, cold or wind. This meant that a centering system was required that was produced in the form of funnels and pins.

Also we have installed 16 spherical bearings with a second plane across the slip plane which can be opened. It goes without saying that all bearings also require centring mechanisms again when being closed.

Analysis and Optimization on Orthotropic Steel Deck System of Hutong Yangtze River Highway and Railway Bridge
Authors: Liu Xiaoguang , Ju Xiaochen
Published: February 2021

The main-span of Hutong Yangtze River Bridge is 1092m, and will be the largest span cable stayed highway and railway bridge after it is built. The steel truss girder and steel box girder were employed in highway and railway orthotropic bridge deck systems, respectively. Because of their complex structures, the mechanical characteristic is difficult to be determined. In order to master the mechanical behavior of the deck systems, Finite Element models on both highway and railway orthotropic bridge decks were established by Abaqus software, and the fine finite element analysis was carried out. Combined with the character of the railway load, the comparative analysis on the force state for the upper plate, lower plate, cross beam web and U-shape rib in the railway deck system was carried on subjected to different train live load forms. Normally the fatigue cracks initiate frequently from the weld between deck plate and U-shape rib and the weld between cross beam web and U-shape rib in highway deck system, therefore, finite element analysis mainly focused on the stress distribution and concentration in these two positions under horizontal and transverse road vehicle wheel load conditions. Meanwhile, the effect of the arc profiles shape on the stress distribution around the weld between cross beam web and U-shape rib was investigated. The results of the analysis demonstrate that the construction details of the deck system are reasonable, which have good mechanical properties. The design of the orthotropic deck for HutongYangtze River Bridge meets the requirements of the steel bridge design codes.
Dynamic Vehicle-Bridge Coupling Analysis with a Finite Element Model Based on Abaqus
Authors: Yang Dong
Published: February 2021

This paper builds bridge models using PYTHON language based on ABAQUS, embeds the vibration equation of vehicle model into the modeling and loading procedure of the bridge, and solves the vehicle equation by taking advantage of the numerical analysis ability of PYTHON. A single finite element software is utilized in the whole solving process, which avoids interaction call between different softwares. Zhai Algorithm explicit integration method is adapted to predict the vertical dynamic response in the next step according to the dynamic response (vertical displacement, vertical velocity) function of the vehicle and bridge in current analysis step. This method is able to calculate the interaction force between the vehicle and bridge in coupled vibration, improve the computing accuracy and reduce calculation work at the same time. The proposed analysis model is verified through an example with respect to coupled vibration.
Evaluation of Strengthening Applications for Old Railway Bridges in Egypt
Authors: Abbas Hussein H. , Hassan Maha Moddather
Published: February 2021

Egyptian railway transportation network is one of the oldest networks worldwide. Recently, an extensive assessment campaign has been initiated for a group of railway steel bridges in Egypt. In many cases, major repair and rehabilitation activities were observed due to accidents that may have happened to the structure such as: fire, derailment, or collision. The strengthening and rehabilitation of the considered bridges usually include - but not limited to - adding steel plates or replacing damaged members. The current study focuses on evaluating the different repair procedures applied on several aging steel railway bridges in Egypt. Field tests and analytical models are used to deduce deviations from the expected behaviour and pinpoint possible defects. The previous performed strengthening and rehabilitation applications are determined. Hence, their effect on the steel bridge behaviour is assessed.
3D non-linear FE analysis of a full scale test to failure of a RC Railway Bridge strengthened with carbon fibre bars
Authors: Puurula Arto Matti , Enochsson Ola , Sas Gabriel , Blanksvärd Thomas , Ohlsson Ulf , Bernspång Lars
Published: February 2021

At a full scale loading test to failure a 50 year old concrete railway trough bridge in Örnsköldsvik, in northern Sweden was tested to failure. The test was a part of the European Research Project “Sustainable Bridges” regarding assessment and strengthening of existing bridges. In the project new calculation methods were developed to capture the behaviour of the bridge during increasing load. The bridge was strengthened in bending with rods of Carbon Fiber Reinforced Polymer (CFRP) before the loading test. Failure was reached for an applied load of 11.7 MN by pulling a steel beam placed in the middle of one of the two spans downwards. The achieved failure was a combination of bond, shear, torsion and bending. The developed model, a 3D -non-linear finite element (FE) model with discrete reinforcement, gave accurate accounts of the response of the bridge. The FE calculations show the effect of the strengthening with CFRP and even the effect of the epoxy when using the Near Surface Mounted Reinforcement (NSMR) strengthening method.
Structural control of high-speed railway bridges by means of fluid viscous dampers
Authors: Rådeström Sarah , Ülker-Kaustell Mahir , Andersson Andreas , Tell Viktor , Karoumi Raid
Published: February 2021

The dynamic response of structures is an important aspect to consider, especially at resonance. Particularly, bridges traversed by trains are at risk, due to the repeated loading with regular interval from the axle and bogie spacings. If the risk of resonance is not accounted for in the design, the vertical acceleration of the bridge deck may exceed the allowed limits of comfort and safety. Hence, alternative, sustainable measures for reducing the vibrations in bridges are required to solve these challenges. This paper presents studies of fluid viscous dampers used to control the dynamic behaviour of high-speed railway bridges. A finite element model is used to investigate the response of an existing bridge, both prior to and after the installation of dampers, and the influence of some parameters on the efficiency of the dampers are analysed. The results from this paper show that the vertical deck acceleration is sufficiently reduced using the proposed solution.
Design and construction of a large railway bridge in a complex traffic junction
Authors: Langedijk Walter , van Lierop Pieter , van Kortenhof Britte
Published: February 2021

To enable widening of the highway A1, a new, large double track railway bridge is being constructed near Amsterdam in The Netherlands. This new structure is part of the SAA project, a large infrastructural project that aims to increase road capacity of the Schiphol-Amsterdam- Almere corridor, to alleviate the current traffic congestion and improve the environmental quality of the area.

The superstructure comprises a steel arch bridge with a diagonal hanger configuration. With a span length of 255m, the bridge is considered to be the largest railway arch bridge in Europe. Because of the required necessity to minimise the hindrance of the road and railway traffic, the erection of the bridge has proven to be the most challenging aspect during the design process. Important design starting points are defined in consultation with the steel contractor during the preliminary design. Steel grade S460, with high client requirements for the material properties, is chosen because of limitations of the bridge weight during transport and installation.

This paper aims to give insight into the design process, the approach to determine the optimal erection methods and the design choices to reach a sustainable bridge with minimal noise emission in favour of the residents.

Bridge over Jökulsá á Fjöllum – when is a glacial flood too large to design for?
Authors: Gudmundsson Gudmundur Valur
Published: February 2021

Volcanic eruptions can result in lava flows, ash fall or when an eruption is under the glacier, large glacial water outburst floods, or jökulhlaup, which can have catastrophic effects. Recent jökulhlaups in Iceland have resulted in the collapse of a few bridges. The existing bridge over Jökulsá á Fjöllum on the Icelandic Ring Road (road no.1) is a suspension bridge with a main span of 107 m, built in 1947, and with a limited capacity for heavy transport. In 2014, a new bridge was being planned and almost ready for tender. However in August 2014 a volcanic eruption started 10 km north of Vatnajökull glacier. There was a considerable likelihood that the eruption would extend under the glacier. Decision was made to change from the previously designed alternative to a cable stayed bridge which provides an alternative flood path, being more robust to an extreme event and much increased flow capacity.
Slide and Turn Gracefully and Economically – A Tale of Four Bridges
Authors: Bednarski Cezary Marek
Published: February 2021

A mechanical opening bridge brings to the art of bridge design the fourth dimension – time, and with it the visual excitement of movement. In terms of cost, in the context of navigation clearances, it can offer savings over a high clearance fixed bridge with its ramps and approaches. An opening bridge can be designed to have a minimal impact on, for example, a historic urban context. This paper presents 4 openable bridges designed by the author with teams of engineers. Two of them, Copenhagen ( sliding ) and Gdansk ( turning ), both set in a protected urban context, were competition winners. Two examples in London were studies for Transport for London (TFL), the London transport authority. The recently completed Copenhagen bridge took years to build mainly due to client’s weaknesses in the process of managing its procurement and construction. As such it offers useful lessons. This paper presents some aspects of its design and construction process. The competition winning turning bridge in Gdansk is at detailed design stage and is yet to be built. There are no immediate plans to advance any of the two London bridge concepts.
The Moveable Structure of the Dome for the Largest Solar Telescope (DKIST)
Authors: Murga Gaizka , Larracoechea Ibon , Bilbao Armando
Published: February 2021

The Daniel K. Inouye Solar Telescope (DKIST), formerly the Advanced Technology Solar Telescope (ATST), is a solar telescope currently under construction at the Haleakalā High Altitude Observatory Site in Maui, Hawai’i. When completed, it will be the largest solar telescope in the world, with unprecedented abilities to view details of the Sun.

The DKIST dome is the large moveable structure about 26m in diameter and 22m high, which protects the telescope and its instrumentation. During the observation, it rotates together with telescope and positions by means of a large moveable shutter the aperture through which the telescope observes with millimetric accuracy, protecting the telescope and its delicate instrumentation from the wind shaking and the solar radiation.

The proposed design is based on a multi-sector shutter system arrangement with an innovative crawler drive system (IDOM patent) assembled on two steel fabricated arch girders. These arch girders supported on a steel fabricated base ring and stiffened by a set of vertical and horizontal steel trusses, the secondary structure. Beneath the base ring a set of bogies with steel wheels allows the rotation of the whole structure.

This structure has been designed and optimized so as to ensure the appropriate mechanism- structure interaction and to withstand the Minimum Design Loads for Buildings and Other Structures as defined by ASCE 7-05 for the Site. The later has become a significant design driver as Hawaii is both a hurricane prone area and a seismic active region.

This paper describes the design proposed by IDOM for this mechanism and how it has been implemented through the different phases of the Project: Design, Fabrication, Factory Assembly and Testing, Packaging and Transport and Site Assembly and Testing.

The Articulated Funiculator is a quantum leap in vertical transportation in tall buildings, deep underground subway stations and deep mines. The Funiculator is an integrated vertical transportation system, not just an elevator. The Funiculator is a connected system of pods that moves people in masse, a vertical sky subway system. A single Funiculator system utilizes shaft sharing and requires only two vertical shafts which dramatically increases the percentage of usable floor space in tall buildings and reduces the amount of tunneling in deep subway stations and deep mines.
Temporary Support Design for Cross Passage Construction
Authors: Yeruva Ramana Reddy
Published: February 2021

The temporary support design for the cross-passages construction are estimated by using the Q- value assessment of Barton (2013) and validation of Q-value system using finite element analysis package PLAXIS 2D. The Q-value is obtained from the GIRs and from face-mapping on site to provide the appropriate rock support solution. The Barton Q-value is an empirical approach, validation of the minimum support category is required to ensure its applicability to the site specific ground conditions. The validation of Q-value system is carried out by using finite element analyses with Mohr-Coulomb constitute model. The unsupported cross passages excavation are considered in finite element analyses and the results shows that the rock is self-supporting and Barton Q-value system is appropriate to the ground conditions encountered.

Published: February 2021

Le présent article se propose d’exploiter les possibilités et les limites d’incorporation du rire aux processus éducatifs, pratique rare dans les espaces pédagogiques. Pour ce faire, dans un premier temps on s’attachera à rappeler quelques théories sur le rire. Dans un second temps, en s’appuyant essentiellement sur l’infiltration (insertion) et le filtrage (sélection) du rire dans l’ambiance pédagogique, on se penchera sur une critique philo-pédagogique où l’on discute le rapport de transitivité entre la vie et l’école. Tout en prenant compte de la présence du rire dans le discours rhétorique et sa proximité avec la notion de parrhêsia, on défend la problématisation de l’expérience scolaire qui dépasse les limites du logocentrisme et de l’austérité dans l’Éducation

Headshot: jogos digitais, violência e ensino da Arte
Authors: Bahia Ana Beatriz
Published: February 2021

O artigo aborda a pertinência e possibilidades de se trabalhar jogos digitais violentos no âmbito do ensino da arte. Primeiramente, retoma relato de prática docente (TONIN, 2018), quando jogos de estética e jogabilidade diferenciais foram utilizados em prática de ensino de arte, fazendo eclodir a demanda dos alunos por vivenciar tal proposta com jogos FPS (first-person shooter) e da série Grand Theft Auto (GTA). Em seguida, discute porque e em que sentido é relevante acolher tal demanda, tendo em vista o modo como os jogos digitais são mencionados na BNCC. Então, discute como acolher tal demanda no âmbito no ensino de arte, considerando que tais títulos têm Classificação Indicativa para maiores de idade. Servindo-se de contribuições teórico-metodológicas da Cultura Visual (MARTINS, 2012; AGUIRRE, 2009; HERNANDEZ, 2005), propõe trabalhar a partir das imagens que emergem da experiência com tais jogos – e não jogando o jogo necessariamente –, mas tendo em vista características próprias da experiência estética imersiva, em espaços de simulação (MANOVICH, 2006; FRASCA, 2004). Para subsidiar tal prática, o artigo traz uma seleção de artefatos visuais que abordam a violência por diferentes meios, estéticas e poéticas, destacando art mods (modificações artísticas) de jogos FPS.  O artigo estabelece relações entre os modos de ver, de ocultar e de significar a violência, tanto em Arte (SELKGMANN-SILVA, 2003) quanto em jogos digitais (ALVES, 2004; PHILLIPS, 2018; GALLOWAY, 2006), esboçando caminhos para se mediar o olhar crítico-poético sobre as imagens da violência que permeiam a sociedade contemporânea.

Como metodologia, utilizou-se um modelo cíclico de desenvolvimento de softwares voltado para jogos, composto por cinco etapas: Inspiração, Conceito, Design, Desenvolvimento e Avaliação/Testagem. Após um período de 16 meses, foi oportunizada uma versão inicial do produto. Para validação deste CDA, foram aplicados testes com alunos de escolas públicas, de idades entre 8 e 12 anos. A resposta dos participantes ao CDA foi positiva pois o jogo possibilitou a identificação e reflexão acerca da temática proposta.

Trata-se de uma pesquisa qualitativa, que contemplou observação, entrevistas semiestruturadas e análise técnica e pedagógica do GCompris, utilizando um instrumento desenvolvido pelo grupo de pesquisa em Tecnologia Digital e Aquisição do Conhecimento [AVALIAÇÃO CEGA]. Os dados obtidos na análise e na observação do uso do GCompris pelos alunosrevelaram algumas lacunas técnicas e pedagógicas, potencialidades educativas e contribuições desse recurso para os multiletramentose a necessidade de capacitar docentes para desenvolverem práticas pedagógicas que atendam às novas demandas sociais e tecnológicas dos estudantes.
Transpondo saberes para um app de Educação Ambiental baseada no lugar em Realidade Aumentada
Authors: Krause Frederico Coelho , Santos Gilberto Lacerda
Published: February 2021

Transposição didática (Chevallard, 1998) se refere à passagem do saber sábio, produzido nos círculos acadêmicos, ao saber a ensinar, presente nos currículos, e deste ao saber ensinado nas escolas. No que concerne à produção de aplicativos educativos para educação ambiental baseada no lugar, levantamos a hipótese da necessidade de inclusão da análise do saber aprendido pelos alunos para que a Transposição Didática seja efetiva. O objetivo do trabalho relatado neste artigo foi verificar essa necessidade para a efetivação da transposição didática com vistas à educação ambiental baseada no lugar, por meio do processo de concepção, desenvolvimento e teste de um aplicativo, intitulado O Ribeirão e a Escola, experimentado em seis turmas de ensino fundamental da Escola Classe 05 de Sobradinho, Distrito Federal.

A metodologia utilizada é a pesquisa-formação na cibercultura, com o desenvolvimento da pesquisa ocorrendo ao longo de processos formativos. O objetivo é compreender como ocorre a autoria de desenhos didáticos com aplicativos na educação online, considerando a articulação entre ambientes virtuais de aprendizagem web e interfaces móveis. O campo de pesquisa delineou-se durante o curso Formação de Docentes para a Educação Online do Instituto Federal do Rio de Janeiro (IFRJ). Como achado, tem-se a noção subsunçora “Autoria de desenhos didáticos com interfaces móveis na educação online”, fruto da reflexão sobre uma pedagogia que considere os aplicativos e as transformações decorrentes da mobilidade ubíqua.
Avaliação do uso dos dispositivos móveis no ensino de Química por meio da adaptação dos Modelos de Aceitação (TAM) e Ajuste (TTF)
Authors: Cardoso Lediana Pereira , Cleophas Maria das Graças
Published: February 2021

Cada vez mais, as tecnologias móveis fazem parte de praticamente todos os contextos atrelados à vida humana. Contudo, quando se analisa o uso dessas tecnologias para o cenário educacional, percebe-se a existência de alguns paradigmas que ainda não foram superados. Este estudo usa o modelo adaptado de aceitação da tecnologia (Technology Acceptance Model - TAM), assim como o de ajuste Tecnologia-Tarefa (Task-Technology Fit –TTF) para examinar a aceitabilidade e ajuste de uma Sequência Didática que proporcionou a inserção da tendência BYOD na sala de aula de Química, por meio do uso de uma estratégia mobile learning que visava aplicar os dispositivos móveis dos alunos, em especial, os smarthones, como aporte ao processo de ensino e aprendizagem. Vale destacar que o estudo utilizou um desenho de investigação misto (qualitativo-quantitativo), e os dados foram coletados utilizando-se um questionário estruturado com alunos da Educação Básica de uma escola pública (N = 89). Os resultados apontam que a inserção das tecnologias móveis no ensino de química de modo planejado em sala de aula agregou benefícios para a aprendizagem dos alunos.

Implicações textual-discursivas na composição do gênero meme: uma análise de sua constituição na virtualidade
Authors: Cardoso Neide Silva , Cavalcanti Ricardo Jorge de Sousa , Lima-Duarte Flávia Karolina
Published: February 2021

Este estudo visa refletir o uso da linguagem nas redes sociais e das práticas de comunicação na atualidade, cujas leitura e ressignificação do gênero Meme são, em grande parte, uma construção coletiva em espaços virtuais de interação social. Pretendemos mostrar os resultados de uma análise textual-discursiva do gênero Meme, em que a produção se dá em meios multimodais. Para o estabelecimento da discussão, apoiamo-nos em Barthes (1977), Kress e van Leeuwen (2006), Rojo (2009), Ribeiro (2016), Marcuschi e Xavier (2010), entre outros. A pesquisa é de natureza qualitativa e caracteriza-se como uma análise documental, pois foi realizada nas principais redes sociais de compartilhamento de conteúdos e o corpus de análise foi selecionado usando critérios de propagação desses Memes. Os resultados apontam para a necessidade de um olhar mais acurado em relação ao gênero em foco, inclusive em contextos de didatização de Língua Portuguesa.
A defesa da escola pública e gratuita a partir da concepção de homem e história do Materialismo Histórico e Dialético
Authors: Andrade Susimeire Vivien Rosotti de , Pereira Patrícia Sandalo , Lopes Anemari Roesler Luersen Vieira
Published: February 2021

Este artigo, derivado de um estudo teórico de uma tese em andamento, apresenta uma pesquisa bibliográfica visando a compreensão da contribuição da concepção do homem e história fundamentada no Materialismo Histórico-Dialético (MHD) na luta em defesa da escola pública e gratuita. O MHD foi elaborado por Karl Marx (1818-1883) e Friedrich Engels (1820-1895), e criou meios para analisar cientificamente o funcionamento das sociedades e da história. Nele constata-se que o homem, como ser histórico, social e político, a partir do trabalho, transcendeu a natureza e, como consequência, acabou modificando a sua própria. Nessa perspectiva, a história da humanidade é a história da luta de classes e a escola pública e gratuita considera a educação como apropriação cultural, legitimando sua compreensão de que os seres humanos são o concreto e que, além de viver a história, também a criam, consequentemente, não é possível aceitar o determinismo da natureza humana que visa tornar pessoas meros objetos para melhor explorá-las.

A produção científica na área de acessibilidade nas revistas brasileiras de educação especial
Authors: Matos Maria Almerinda de Souza , Souza Danilo Batista de
Published: February 2021

Neste estudo, de natureza bibliográfica, sobre as publicações referentes à acessibilidade, utilizamos os sites da Revista Brasileira de Educação Especial (RBEE/ABPEE) e da Revista Educação Especial (REE/UFSM). Encontramos 21 publicações, sendo 11 artigos na RBEE e 10 na REE, os quais foram analisados por categorias, são elas: 1) Ano e quantidade de artigos publicados; 2) Tipo de autoria dos artigos; 3) Área de formação de autores e coautores; 4) Gênero textual dos artigos e; 5) Temas relacionados à acessibilidade. Após o exposto das produções científicas, muitas pesquisas apontam que alguns dos fatores que interferem na concretização da real inclusão são, por exemplo, a lacuna existente na formação dos professores a respeito da inclusão, da acessibilidade, a atuação com pessoas com deficiência, o conhecimento das políticas públicas, a falta de estrutura física nas escolas para que todos possam usufruir os espaços e as dificuldades e o assistencialismo aos alunos com deficiência.
