[pt] FORMAÇÃO DE PROFESSORES E A PRÁTICA PEDAGÓGICA COM TECNOLOGIAS: ESTUDO DA CORRELAÇÃO NA BASE TIC EDUCAÇÃO 2014 / [en] TEACHERS TRAINING AND EDUCATIONAL PRACTICE WITH TECHNOLOGIES: A CORRELATIONAL STUDY ON THE TIC EDUCAÇÃO 2014 DATA BASISALINE DE MENDONÇA BRASILINO 14 November 2017 (has links)
[pt] Momentos de formação continuada para o uso pedagógico das Tecnologias da Informação e Comunicação (TIC) têm por objetivo promover a integração do uso das TIC nas práticas pedagógicas. Com o intuito de contribuir para a análise dos resultados alcançados por esses momentos de formação, este trabalho estudou a relação entre a participação do professor nesses momentos e as suas práticas com TIC. Investigamos a presença das tecnologias nos momentos de formação e analisamos as políticas públicas de disseminação das TIC nas escolas. Paralelamente, realizamos uma pesquisa quantitativa com o objetivo de estudar a correlação entre as variáveis latentes formação específica em TIC e uso pedagógico de TIC pelos professores com os dados da TIC Educação 2014. Para atribuirmos uma medida a essas variáveis latentes, construímos quatro escalas utilizando a Teoria de Resposta ao Item (TRI). Duas escalas de formação, uma que considera os momentos institucionalizados e outra os informais dos quais os professores participaram; e duas escalas de uso, uma considerando as atividades com os alunos e outra as ações de preparação de aula. Para explicar a variável dependente uso pedagógico de TIC, construímos um modelo de regressão linear considerando como variáveis explicativas: as variáveis de formação específica em TIC e as variáveis de controle. Os resultados principais indicam que o uso pedagógico de TIC (Atividade e Preparação) é influenciado positivamente pela formação específica em TIC Institucionalizada e Informal, disciplina específica em TIC na graduação, renda mensal familiar e titulação, negativamente pela idade, e não é influenciado por curso específico em TIC, sexo e cor/raça. / [en] Moments of professional training for the pedagogical use of information and communication technologies (ICT) aim to promote the integration of the use of ICT in pedagogical practices. In order to contribute to the analysis of results achieved by these training moments, this dissertation presents a study on the relationship between teacher s participation in these moments and his practices with ICT. We investigate the presence of technology in formation and we analyzed public policies of dissemination of ICT in schools. Meanwhile, we conducted a quantitative research to study the correlation between those latent variables: specific training in ICT and used ICT pedagogy on the TIC Educação 2014 data basis. To assign a measure to latent variables, we constructed four scales using the Item Response Theory (IRT). Two of them are training scales: the first one considers the institutionalized moments, while the second one takes the informative information of the assistant teachers into account. The other two are scales of use, one considering the activities with students and the other the actions of preparing classes. In order to explain the dependent variable use of ICT for pedagogy, we composed a linear regression model including as explanatory variables: the specific training variables in ICT and the control variables. The main results indicate that the pedagogical use of ICT is positively influenced by institutionalized and informal training, specific subjects in undergraduate school, family income and academic degree. However, they also show that the pedagogical use is negatively influenced by age, and is not influenced by any specific course, gender and skin colour/race.

New marketing opportunities for fixed line telecommunication operators in South Africa : a strategic evaluationAli, Fuaad 09 1900 (has links)
Information, communication and broadcasting convergence is changing the business landscape
in South Africa, as organisations adopt new converged information, communication technology
(ICT) products and services to satisfy the needs of customers. Simultaneously, major changes are
taking place in the South African telecommunications business environment creating new
marketing opportunities and threats for Telkom SA, the only fixed line telecommunication
operator in South Africa.
Some of the findings of the study are
• the commodization of the fixed line telecommunication network
• political and regulatory changes are reshaping the telecommunications landscape by allowing
the entry of new competitors
• new technological innovations in Information Communication Technology (ICT) and mobile
communication is driving change
• social and economic change is fueling the speed of environmental change
poor economic climate is quickening the competitive pace amongst South African businesses
forcing them to attain efficiencies and effectiveness for survival
• organisations worldwide are competing for limited resources and markets and turning to ICT
to achieve their objectives
• customer needs are changing - demanding better and innovative communication products and
services - providing opportunities to competitors
• the Internet is reshaping traditional business models as businesses are seeking to establish
competitive advantages through the Internet
• the migration of the Internet to the mobile telephony sector
These changes are creating new marketing opportunities and threats for South African fixed line
telecommunication operators and are threatening the survival of fixed line telecommunication
operators worldwide and in South Africa. Information Technology, broadcasting and
telecommunication technology convergence, has created many new ICT products and services
opportunities that telecommunication competitors are offering existing customers of the fixed
line operators network indicating lethargy from their side. In order for the fixed line operators to
survive they must apply innovation and revise their strategic planning models. / Business Management / DCOM (Business Management)

Secondary-school teachers’ information communication technology competencies in classroom practicesMolotsi, Abueng Rachael 11 1900 (has links)
The world today is continuously influenced by ever-changing technological developments introducing new knowledge and applications into society’s culture, and social, political, and educational environments (Angeli & Valanides, 2009:154). Consequently, the educational environment as a branch of human knowledge needs to be redesigned in order to keep pace with current technological developments. Technological integration in education is inevitable and teachers are faced with the challenge of being competent ICT users.
Internationally, there is growing consensus that the integration of ICT in education increases 21st-century learners’ skills (Blignaut, Hinostroza, Els & Brun 2010:89). Technology offers learners a better understanding of concepts with the use of visual interactions that enable them to store it in their long-term memories. For most teachers this is an obstacle, because the use of Information Communication Technology (ICT) was not included as part of their teacher training programmes (Tropakci, n.d.:1; Afshari, Bakar, Luan, Samah & Fooi, 2009:89). By obvious implication, 21st-century learners require teachers who are knowledgeable and possess technological skills so that they can facilitate technology-integrated lessons.
This study investigated secondary-school teachers’ Information Communication Technology competencies in classroom practices within Bojanala District, North West Province, South Africa in order to suggest a strategy that could assist teachers in effectively integrating ICTs in teaching and learning. As a former Computer Application Technology (CAT) teacher, I was prompted to conduct this study by my involvement, experiences and observations of using ICT in teaching and learning. The picture of teachers’ ICT competencies in the Bojanala District where the fieldwork was conducted indicates that of the 134 secondary schools in the district only 25 have integrated ICTs into their teaching and learning. Furthermore, some secondary schools in the district have computer laboratories that are not being utilised. This indicates that the participating teachers were not competent ICT users, with no strategy that could be implemented to assist them in effectively integrating ICTs in their classroom practices. Despite the introduction of the South African policy on e-Education in the education system, little has been done in terms of its implementation. According to this policy, every learner in the General Education Training (GET) and Further Education Training bands (FET) should have been technologically savvy by 2013 (DoE, 2004:17).
The research question guiding this study was: What are secondary school teachers’ ICT competency skills in classroom practices? The study was grounded in the interpretive epistemological paradigm. I employed a qualitative research method and the research design comprised collective or multiple case studies. Four secondary schools were selected on the basis of their proximity to my residence. Eight secondary-school teachers were invited to participate in this study. These teachers were purposively sampled on the basis of their expertise in the use of ICTs in teaching and learning.
The data collection strategies were semi-structured interviews, non-participant observation and document analysis. Data analysis was done according to the four key steps of the data analysis process suggested by Anderson (209:156,157), while the procedure of analysing data which was adapted from Creswell (2007:214). Ethical consideration was maintained by not disclosing participants’ personal information. To ensure trustworthiness in this study, four issues were established, namely credibility, transferability, dependability and transferability. / Curriculum and Instructional Studies / D. Ed.

An exploration of information and communication technology use on the part of Eritrean refugees in Rome, ItalyOpas, Matthew E. 08 June 2012 (has links)
Thesis explores the ways in which Information and Communication Technology (ICT)use, specifically that of telephones and the Internet, impacts the lives of Eritrean refugees in Rome, Italy. Informal interviews, semi-structured interviews, and participant observation were carried out in a 'center of second reception.' Results show that information obtained through the use of ICT acts on the imaginations of refugees, encouraging or discouraging movement to alternative locations. ICT use can help maintain a sense of emotional "closeness" to family members abroad for some,
but not for others. Limitations in access to ICT exist for the refugees and their families in Eritrea that crosscut multiple socio-demographic categories. Finally, surveillance, enacted through ICT use, negotiates power between the Eritrean state and its subjects in the diaspora. / Graduation date: 2012

Exploring the Effects of ICT on Environmental Sustainability: From Life Cycle Assessment to Complex Systems ModelingAhmadi Achachlouei, Mohammad January 2015 (has links)
The production and consumption of information and communication technology (ICT) products and services continue to grow worldwide. This trend is accompanied by a corresponding increase in electricity use by ICT, as well as direct environmental impacts of the technology. Yet a more complicated picture of ICT’s effects is emerging. Positive indirect effects on environmental sustainability can be seen in substitution and optimization (enabling effects), and negative indirect effects can be seen in additional demand due to efficiency improvements (rebound effects). A variety of methods can be employed to model and assess these direct and indirect effects of ICT on environmental sustainability. This doctoral thesis explores methods of modeling and assessing environmental effects of ICT, including electronic media. In a series of five studies, three methods were at times applied in case studies and at others analyzed theoretically. These methods include life cycle assessment (LCA) and complex systems modeling approaches, including System Dynamics (SD) and agent-based (AB) modeling. The first two studies employ the LCA approach in a case study of an ICT application, namely, the tablet edition of a Swedish design magazine. The use of tablets has skyrocketed in recent years, and this phenomenon has been little studied to date. Potential environmental impacts of the magazine’s tablet edition were assessed and compared with those of the print edition. The tablet edition’s emerging version (which is marked by a low number of readers and low reading time per copy) resulted in higher potential environmental impacts per reader than did the print edition. However, the mature tablet edition (with a higher number of readers and greater reading time per copy) yielded lower impacts per reader in half the ten impact categories assessed. While previous studies of electronic media have reported that the main life-cycle contributor to environmental impacts is the use phase (which includes operational electricity use as well as the manufacture of the electronic device), the present study did not support those findings in all scenarios studied in this thesis. Rather, this study found that the number of readers played an important role in determining which life-cycle phase had the greatest impacts. For the emerging version, with few readers, content production was the leading driver of environmental impacts. For the mature version, with a higher number of readers, electronic storage and distribution were the major contributors to environmental impacts. Only when there were many readers but low overall use of the tablet device was the use phase the main contributor to environmental impacts of the tablet edition of the magazine. The third study goes beyond direct effects at product- and service-level LCAs, revisiting an SD simulation study originally conducted in 2002 to model indirect environmental effects of ICT in 15 European countries for the period 2000-2020. In the current study, three scenarios of the 2002 study were validated in light of new empirical data from the period 2000–2012. A new scenario was developed to revisit the quantitative and qualitative results of the original study. The results showed, inter alia, that ICT has a stimulating influence on total passenger transport, for it makes it more cost- and time-efficient (rebound effects). The modeling mechanism used to represent this rebound effect is further investigated in the fourth study, which discusses the feedback loops used to model two types of rebound effects in passenger transport (direct economic rebound and time rebound). Finally, the role of systems thinking and modeling in conceptualizing and communicating the dynamics of rebound effects is examined. The aim of the fifth study was to explore the power of systems modeling and simulation to represent nonlinearities of the complex and dynamic systems examined elsewhere in this thesis. That study reviews previous studies that have compared the SD and AB approaches and models, summarizing their purpose, methodology, and results, based on certain criteria for choosing between SD and AB approaches. The transformation procedure used to develop an AB model for purposes of comparison with an SD model is also explored. In conclusion, first-order or direct environmental effects of ICT production, use, and disposal can be assessed employing an LCA method. This method can also be used to assess second-order or enabling effects by comparing ICT applications with conventional alternatives. However, the assessment of enabling effects can benefit from systems modeling methods, which are able to formally describe the drivers of change, as well as the dynamics of complex social, technical, and environmental systems associated with ICT applications. Such systems methods can also be used to model third-order or rebound effects of efficiency improvements by ICT. / Den ökande produktionen och konsumtionen av produkter och tjänster inom informations- och kommunikationsteknik (IKT) leder till en ökning av den globala elanvändningen samt direkta miljökonsekvenser kopplade till IKT. Men IKT har även indirekta miljömässiga effekter. Dessa kan vara positiva till exempel genom substitutions- och optimeringseffekter eller negativa genom att till exempel ge upphov till ytterligare efterfrågan på grund av effektivisering (så kallade reboundeffekter). Olika metoder kan användas för att modellera och bedöma både direkta och indirekta effekter av IKT. Syftet med denna avhandling är att undersöka metoder för modellering samt att studera miljöeffekter av IKT och elektronisk media med hjälp av livscykelanalys (LCA) och även modellering av komplexa och dynamiska system, samt simuleringsteknik, så som System Dynamics (SD) och agentbaserad (AB) modellering. Avhandlingen omfattar fem artiklar (artikel I-V). Artikel I & II beskriver resultaten från en fallstudie där miljöeffekter kopplade till en svensk tidskrift studeras med LCA. Tidskriftens version för surfplatta samt motsvarande tryckta version studeras och jämförs. Artikel III går ett steg vidare från produktnivåns LCA. Artikeln återkopplar till en SD simuleringsstudie som ursprungligen genomfördes under 2002. Simuleringsstudien gällde framtida miljöeffekter av IKT i 15 europeiska länder med tidspespektivet 2000-2020. I artikeln valideras tre scenarier från simuleringsstudien med hjälp av nya empiriska data från 2000-2012 och ett nytt scenario modelleras. Kvantitativa och kvalitativa resultat från den ursprungliga studien diskuteras. Till exempel visar artikel III att IKT har en stimulerande effekt på den totala persontrafiken genom att göra den mer kostnads- och tidseffektiv (reboundeffekt). Modelleringsmekanismen som används för att representera denna reboundeffekt diskuteras vidare i artikel IV. Artikeln belyser och diskuterar den återkopplingsslinga (feedback-loop) som används för att modellera två typer av reboundeffekter kopplade till persontrafik (direkt ekonomisk rebound och tidsrelaterad rebound) samt jämför med en tidigare studie. Artikel IV behandlar också den roll systemtänkande och modellering kan spela i konceptualisering och kommunikation av reboundeffekters dynamik. För att ytterligare undersöka systemmodelleringens och simuleringens möjligheter att representera icke-linjära komplexa och dynamiska system (exempel på sådana diskuteras i artikel III och IV), sammanställer artikel V tidigare studier som jämför SD och AB-metoder och -modeller. Studiernas mål och metod summeras och resultaten med avseende på vilka kriterier som presenteras för att välja mellan SD och AB sammanställs. Även processen för att omvandla en befintlig SD-modell till en AB-modell beskrivs. Avhandlingens slutsats är att LCA och systemmodelleringsmetoder kan vara användbara för att studera IKTs direkta effekter så väl som indirekta effekter på miljön. / <p>QC 20150813</p>

Att lära, att göra, att klara : Förmedling av datortekniska hjälpmedel till barn med synnedsättning. Från förskrivning till vardaglig användning i skola och hem / Learning, doing, becoming self sufficient : Mediation of assistive computer technologies for children who are blind or partially sighted. From prescription to everyday use in school and at home.Åström, Eva January 2009 (has links)
Förmåga att använda informations- och kommunikationsteknik framhålls numeraofta som en förutsättning för delaktighet på lika villkor i samhällslivet. Näraförknippat med detta är de insatser som görs för att överbrygga digitala klyftor isamhället. IKT har gjort deltagandet i samhällslivet mer möjligt för personer medsynnedsättning. Tillgång till teknik innebär dock inte alltid att den kan användas ivardagen. I denna avhandling analyseras den förmedlingsprocess som sker när barnmed grav synnedsättning, genom förskrivning på syncentraler, får tillgång tilldatortekniska hjälpmedel, samt hur barnen därefter tillägnar sig tekniken genom att,med olika stödpersoners hjälp, använda den i skolan och hemmet. Åtta barn (mellan7-18 år) från två syncentralers upptagningsområden deltog i studien, tillika medderas föräldrar, stödpersoner i skolan samt personal (datortekniker och anpassningslärare)från syncentralerna. Undersökningsmaterialet har samlats in genom intervjuer,samtal och observationer. Barnen har skrivit aktivitetsrelaterade dagböcker. Förmedlingsprocessen involverar många personer från flera organisationer och ärutsträckt i tid och rum. Olika rationaliteter ställs mot varandra när professionelltverksamma från syncentral och skola, tillsammans med föräldrar ska möjliggöra förbarnen att ta tekniken i bruk. Med utgångspunkt från datorn som hjälpmedel diskuterastre projekt vars mål är viktiga för barnet att nå: att lära sig, att bli socialtdelaktig och att bli självständig. Dessa projekt står ofta i konflikt med varandra, tillexempel barnens önskan att träna på datorn samtidigt som de vill leka med sinakamrater. Med en tidsgeografisk ansats analyseras situationer där konflikter uppstår,samt vilka avvägningar och försök till samordning som görs av de inblandadeparterna. Skolan utgör ett område där den övergripande samhälleliga ambitionen omett liv på lika villkor ska konkretiseras. Analysen pekar på att uppmärksamhet börriktas såväl mot den individcentrerade kompensatoriska användningen av tekniskahjälpmedel, som mot skolans uppläggning av undervisningen (strukturell förändring förtillgänglighet). Ett helhetsperspektiv på förmedlingsprocessen möjliggör långsiktigplanering där tidsrumsliga dimensioner betraktas och dess fragmentering minskas. / The ability to use information and communication technology is regarded today as acondition for participation in society. Closely associated with this are measurestaken to reduce the digital divide in society. Computer technology is accepted asmaking it possible for people with disabilities to manage most things on their ownthat previously required some help of others. However, access to technology doesnot necessarily equal usability. This thesis explores and analyses the mediationprocess that occurs when children with visual impairment, access assistive computertechnologies, and how these, by the help of support persons, are used in home and atschool. Eight children (between seven and eighteen years of age) were included inthe study, as well as their parents, support persons in school and professionals fromthe Low Vision Clinics. Research data have been collected through interviews,conversations, observations and activity oriented diaries. The mediation processinvolves a number of persons and organisations and is both organisationally complexand extended in time and space. Different rationalities are set against eachother, when professionally active persons from the Low Vision Clinics and schools,together with parents make it possible for the children to use the assistive devices.From the standpoint of the computer as an aid, three projects are discussed whosegoals are important for the child to achieve to be able to, in the short and long run,live life to the full. These projects are ‘learning’, ‘becoming socially involved’ and‘becoming independent’. The projects can often be in conflict with each other; forexample the children’s desire to practice on the computer against their wanting toplay with their friends at the same time. With a time-geographic approach,situations in which conflicts and trade-offs arise, as well as the coordination effortsmade by those involved, are analysed. The school constitutes an area in which theoverreaching societal ambition of a life on equal terms is realised. This studydiscusses how compensation for the individual as well as structural change foraccessibility manifests itself in organisation, structures and supportive efforts.

Communication of sustainability information and assessment within BIM-enabled collaborative environmentZanni, Maria Angeliki January 2017 (has links)
Sustainable performance of buildings has become a major concern among construction industry professionals. However, sustainability considerations are often treated as an add-on to building design, following ad hoc processes for their implementation. As a result, the most common problem to achieve a sustainable building outcome is the absence of the right information at the right time to make critical decisions. For design team members to appreciate the requirements of multidisciplinary collaboration, there is a need for transparency and a shared understanding of the process. The aim of this study is to investigate, model, and facilitate the early stages of Building Information Modelling (BIM) enabled Sustainable Building Design (SBD) by formalising the ad hoc working relationships of the best practices in order to standardise the optimal collaboration workflows. Thus, this research strives to improve BIM maturity level for SBD, assisting in the transition from ad hoc to defined , and then, to managed . For this purpose, this study has adopted an abductive research approach (iterative process of induction and deduction) for theory building and testing. Four (4) stages of data collection have been conducted, which have resulted in a total of 32 semi-structured interviews with industry experts from 17 organisations. Fourteen (14) best practice case studies have been identified, and 20 incidents narratives have been collected applying the Critical Decision Method (CMD) to examine roles and responsibilities, resources, information exchanges, interdependencies, timing and sequence of events, and critical decisions. As a result, the research has classified the critical components of SBD into a framework utilising content and thematic analyses. These have included the definition of roles and competencies that are essential for SBD along with the existing opportunities, challenges, and limitations. Then, Schedules of Services for SBD have been developed for the following stages of the RIBA Plan of Work 2013: stage 0 (Strategic Definition), stage 1 (Preparation and Brief), and stage 2 (Concept Design). The abovementioned SBD components have been coordinated explicitly into a systematic process, which follows Concurrent Engineering (CE) principles utilising Integrated DEFinition (IDEF) structured diagramming techniques (IDEF0 and IDEF3). The results have identified the key players roles and responsibilities, tasks (BIM Uses), BIM-based deliverables, and critical decision points for SBD. Furthermore, Green BIM Box (GBB) workflow management prototype tool has been developed to analyse communication and delivery of BIM-enabled SBD in a centralised system (Common Data Environment, CDE). GBB s system architecture for SBD process automation is demonstrated through Use Case Scenarios utilising the OMG UML (Object Management Group s Unified Modelling Language) notation. The proposed solution facilitates the implementation of BIM, Information Communication Technology (ICT), and Building Performance Analysis (BPA) software to realise the benefits of combining distributed teams expertise holistically into a common process. Finally, the research outcomes have been validated through academic and industrial reviews that have led to the refinement of the IDEF process model and framework. It has been found that collaborative patterns are repeatable for a variety of different non-domestic building types such as education, healthcare, and offices. Therefore, the research findings support the idea that a detailed process, which follows specified communication patterns, can assist in achieving sustainability targets efficiently in terms of time, cost, and effort.
