ACME - Mòdul d'usuaris convidats

El projecte ACME va néixer, l’any 1998, amb la finalitat de millorar la docència de les matemàtiques en els estudis d’Enginyeria Industrial i Enginyeries Tècniques de l’Escola Politècnica de la Universitat de Girona, amb la intenció de buscar la manera de que els alumnes s’impliquessin i participessin més activament en aquesta matèria fent ús de la xarxa com a via de comunicació. El projecte ACME, Avaluació Continuada i Millora de l’Ensenyament, és una eina d’e-learning que té com a objectiu fer una avaluació continuada dels alumnes a través d’uns dossiers personalitzats de problemes que el professor proposa. El sistema permet fer el seguiment, per part del professor, del progrés del conjunt de la classe, o d’un alumne individual, en una assignatura concreta. Això fa que l’ACME tingui un gran valor pedagògic. Els objectius d’aquest projecte final de carrera són els següents: • Desenvolupar un sistema de gestió d’usuaris convidats que ens permeti acceptar o denegar l’accés a usuaris que prèviament han fet una petició per poder utilitzar l’ACME. • Crear un sistema que faciliti la tasca d’assignar als usuaris els temes i els problemes més adients pel seu perfil. • Desenvolupar tot un seguit de millores i ampliacions amb la intenció d’integrar el nou mòdul dins les interfícies existents: Ampliar la interfície d’administració en l’apartat d’usuari amb la opció per gestionar els usuaris convidats. Ampliar la interfície d’administració en l’apartat del quadern de problemes amb les opcions adients per tal de gestionar les assignatures dels convidats.

Performing knowledge requirements analysis for public organisations in a Virtual Learning Environment: a social network analysis approach

This paper describes an application of Social Network Analysis methods for identification of knowledge demands in public organisations. Affiliation networks established in a postgraduate programme were analysed. The course was executed in a distance education mode and its students worked on public agencies. Relations established among course participants were mediated through a virtual learning environment using Moodle. Data available in Moodle may be extracted using knowledge discovery in databases techniques. Potential degrees of closeness existing among different organisations and among researched subjects were assessed. This suggests how organisations could cooperate for knowledge management and also how to identify their common interests. The study points out that closeness among organisations and research topics may be assessed through affiliation networks. This opens up opportunities for applying knowledge management between organisations and creating communities of practice. Concepts of knowledge management and social network analysis provide the theoretical and methodological basis.

Genetic variation and population structuring in two brooding coral species (Siderastrea stellata and Siderastrea radians) from Brazil

Siderastrea stellata and S. radians are scleractinian coral species that present a remarkable overlap of diagnostic characteristics and sympatric distribution. Moreover, both are viviparous with similar reproductive strategies and with a gregarious larval behavior. Samples of both species from the Brazilian coast were analyzed using 18 isozymic loci to quantify their genetic variability and populational structure. Results confirmed species identity, high intrapopulational variability and revealed moderate genetic structuring among all samples (S. stellata: F(ST) = 0.070; S. radians: F(ST) = 0.092). Based on genotypic diversity analysis, there was evidence that local recruitment may have a minor role in the populations (mean, G(o) :G(e) = 1.00 +/- 0.0003 SD for S. stellata and 0.99 +/- 0.0023 SD for S. radians). Deviations towards heterozygote deficiencies found in both Siderastrea species could be explained by the Wahlund effect, since there was evidence that populations might be composed of colonies of different ages. In S. radians it is also likely that there is some inbreeding occurring in the studied populations. Despite the brooding pattern and the gregarious larval behavior, our data suggest the occurrence of gene flow along the Brazilian coast. This is the first study on population genetics of Brazilian reef corals.

Revealing the whiteboard to blind students: An inclusive approach to provide mediation in synchronous e-learning activities

Promoting the inclusion of students with disabilities in e-learning systems has brought many challenges for researchers and educators. The use of synchronous communication tools such as interactive whiteboards has been regarded as an obstacle for inclusive education. In this paper, we present the proposal of an inclusive approach to provide blind students with the possibility to participate in live learning sessions with whiteboard software. The approach is based on the provision of accessible textual descriptions by a live mediator. With the accessible descriptions, students are able to navigate through the elements and explore the content of the class using screen readers. The method used for this study consisted of the implementation of a software prototype within a virtual learning environment and a case study with the participation of a blind student in a live distance class. The results from the case study have shown that this approach can be very effective, and may be a starting point to provide blind students with resources they had previously been deprived from. The proof of concept implemented has shown that many further possibilities may be explored to enhance the interaction of blind users with educational content in whiteboards, and further pedagogical approaches can be investigated from this proposal.

Is the unfolding of the group discussion off-pattern? Improving coordination support in educational forums using mobile devices

A forum is a valuable tool to foster reflection in an in-depth discussion; however, it forces the course mediator to continually pay close attention in order to coordinate learners` activities. Moreover, monitoring a forum is time consuming given that it is impossible to know in advance when new messages are going to be posted. Additionally, a forum may be inactive for a long period and suddenly receive a burst of messages forcing forum mediators to frequently log on in order to know how the discussion is unfolding to intervene whenever it is necessary. Mediators also need to deal with a large amount of messages to identify off-pattern situations. This work presents a piece of action research that investigates how to improve coordination support in a forum using mobile devices for mitigating mediator`s difficulties in following the status of a forum. Based on summarized information extracted from message meta-data, mediators consult visual information summaries on PDAs and receive textual notifications in their mobile phone. This investigation revealed that mediators used the mobile-based coordination support to keep informed on what is taking place within the forum without the need to log on their desktop computer.

An algorithm for automatic checking of exercises in a dynamic geometry system: iGeom

One of the key issues in e-learning environments is the possibility of creating and evaluating exercises. However, the lack of tools supporting the authoring and automatic checking of exercises for specifics topics (e.g., geometry) drastically reduces advantages in the use of e-learning environments on a larger scale, as usually happens in Brazil. This paper describes an algorithm, and a tool based on it, designed for the authoring and automatic checking of geometry exercises. The algorithm dynamically compares the distances between the geometric objects of the student`s solution and the template`s solution, provided by the author of the exercise. Each solution is a geometric construction which is considered a function receiving geometric objects (input) and returning other geometric objects (output). Thus, for a given problem, if we know one function (construction) that solves the problem, we can compare it to any other function to check whether they are equivalent or not. Two functions are equivalent if, and only if, they have the same output when the same input is applied. If the student`s solution is equivalent to the template`s solution, then we consider the student`s solution as a correct solution. Our software utility provides both authoring and checking tools to work directly on the Internet, together with learning management systems. These tools are implemented using the dynamic geometry software, iGeom, which has been used in a geometry course since 2004 and has a successful track record in the classroom. Empowered with these new features, iGeom simplifies teachers` tasks, solves non-trivial problems in student solutions and helps to increase student motivation by providing feedback in real time.

The Use of On-Line Computer adaptive Testing to raise Standardized Test Scores

Nursing school graduates are under pressure to pass the RN-NCLEX Exam on the first attempt since New York State monitors the results and uses them to evaluate the school’s nursing programs. Since the RN-NCLEX Exam is a standardized test, we sought a method to make our students better test takers. The use of on-line computer adaptive testing has raised our student’s standardized test scores at the end of the nursing course.

Development of on-line courses focusing on quality

The purpose of this paper is to show by which means quality in on-line education is achieved at Dalarna University. As a leading provider of online university courses in northern Europe, both in terms of number of students conducting their studies entirely on-line compared to the whole student body, (approximately 70% on-line students all subjects included), Dalarna University has acquired de facto extensive practical experience in the field of information technologies related to distance education. It has been deemed essential, to ensure that the quality of teaching reflects the principles governing the assessment of learning so that on-line education is deemed as comparative to campus education, both from a legal and cognitive point-of-view. Dalarna University began on-line courses in 2002 and it soon became clear that the interaction between the teacher and the student should make its mark in all stages of the learning process in order to both maintain the learners' motivation and ensure the assimilation of knowledge. We will illustrate these aspects by giving examples of what has been done in the recent years in on-line teaching of languages. As this method of teaching is not limited to learning basic language skills, but also to the study of literature, social issues and the language system of the various cultures, our presentation will offer a broad range of areas where the principles of quality in education are provided on a daily basis.

Development, capabilities and technology : an evaluative framework

In this paper we present a framework to be used for evaluation of Information and Communication Technology for Development (ICT4D) projects. The framework is based on Sen´s notion of development as freedom where human capabilities and functionings are seen as key aspects to development. Sen´s capability approach presents an alternative way of seeing and evaluating development (alternative to more traditional ways of measuring development). The approach is based on expanding freedoms, or eliminating unfreedoms, for people so that they can live a life that they have reason to value. Even though Sen is referenced a lot in ICT4D literature the analysis rarely goes further then stating that Sen presents an alternative to traditional ways of development. Reasons can be that the capability approach does not specifically mention technology, in addition to the lack of guidelines presented by Sen on how to use the framework. The aim of this paper is to operationalize the evaluation process and to include a clear role for technology in Sen´s capability framework. The framework is validated with a case on distance education from Bangladesh. 

Strategies for Communicating the Value of AACSB and SACS Accreditation

As institutions expand their distance education programs, administrators must formalize faculty workload expectations for the instruction of online and hybrid courses. This brief reviews faculty workload policies for both face-to-face and distance education courses at six mid-sized master’s institutions. Corresponding workload policies for service and research requirements are also examined. Enrollment capacities for online courses, as well as compensation for the instruction of online courses, are also discussed.

O uso da tecnologia de informação para a educação a distância - estudo dos cursos de administração de empresas

A disseminação da informação e o uso de novas tecnologias têm delineado uma transformação nos processos de ensino-aprendizagem. Uma parte significativa desta transformação está relacionada ao uso da educação a distância como forma de atingir novos públicos e desenvolver novas metodologias de ensino. Estas transformações também estão afetando cada vez mais as corporações, que tem economizado milhões de dólares todos os anos, usando a educação a distância (EAD) para treinar seus empregados de modo mais eficiente e eficaz do que com os métodos tradicionais. Mas, apesar da maciça presença da EAD na Web, o assunto educação ou treinamento a distância ainda é pouco conhecido e, até certo ponto, incompreendido. A interface entre o ensino/treinamento via Web e as universidades tradicionais ou abertas está ainda pouco explorado. O objetivo deste trabalho é fazer um levantamento comparativo entre os cursos universitários que utilizam a educação a distância e os cursos ou treinamentos a distância utilizados pelas empresas. Buscamos identificar na amostra formas de interação e suporte aos alunos semelhantes entre as universidades e as empresas, a fim de reuni-las formando grupos ou segmentos com características similares. Nesta análise identificamos três grandes grupos que melhor caracterizam as metodologias adotadas.

O Uso da tecnologia de informação para a educação a distância no ensino superior - estudo dos cursos de administração de empresas (aprofundamento e ampliação da amostra)

O estudo dos diversos modelos pedagógicos dos cursos a distância utilizados nas principais Instituições de Ensino Superior (IES) brasileiras pode estimular a análise dos profissionais envolvidos com a Educação a Distância (EAD) e, que estejam enfrentado um processo de escolha de uma metodologia para melhor servir aos estudantes que não podem ou optam por não vir para o campus da IES. Um dos principais desafios para as universidades que estão se lançando na EAD é buscar uma linguagem pedagógica apropriada à aprendizagem mediada pelas diversas mídias disponíveis. A ação da tutoria é um elemento essencial, sendo uma das determinantes do sucesso do curso. Neste novo modelo de educação os tutores desempenham mais o papel de facilitadores do que de especialistas, pois os cursos são menos estruturados e mais personalizados, cabendo aos próprios alunos cuidar de sua instrução. O controle sobre o andamento do curso, assim como o acompanhamento permanente do trabalho de professores, dos tutores, dos estagiários de atendimento e da secretaria, são igualmente cruciais, pois a interação com o aluno pode se dar de inúmeras formas e todas elas são essenciais ao sucesso da aprendizagem. A estruturação de uma equipe especializada, composta de pessoas que entendam de tecnologia e de pedagogia e, que trabalhem de forma coesa, podem garantir uma melhor performance da aprendizagem do aluno. O principal objetivo desta pesquisa é, num primeiro momento, fazer o levantamento das diversas metodologias e técnicas adotadas nos cursos a distância oferecidos por instituições de ensino superior (IES) no Brasil para, com base nos dados da pesquisa, efetuar uma análise comparativa a fim de identificar formas de interação e suporte aos alunos semelhantes entre as universidades, ou seja, grupos que possuam características similares tanto relacionados aos projetos pedagógicos de seus cursos, quanto aos materiais utilizados, a estruturação dos cursos, formas de interação aluno/professor, suporte ao aluno, público alvo, tecnologias utilizadas e sistemas de avaliação adotados.

Educação a distância - TV escola e PROINFO: impactos em escolas públicas do Estado do Rio de Janeiro

A educação a distância ganha força como mais uma forma de aprendizagem e como um novo recurso de apoio ao trabalho pedagógico. Por essa razão, existe um grande esforço dos governos, no sentido de priorizar as novas formas de aprendizagem a distância. Acompanhar a evolução das políticas públicas de educação a distância, principalmente os impactos percebidos na qualidade do ensino, é o principal objetivo deste estudo. A pesquisa de campo aconteceu em escolas públicas de Niterói, onde foi observada a evolução dos programas da Secretaria de Educação a Distância SEED, bem como os outros aspectos da pesquisa em si. Considerando a atualidade do tema, foi imprescindível, além da revisão na literatura específica e das referencias bibliográficas usuais, fundamentar a argumentação da autora com periódicos e outros conhecimentos pesquisados na internet, através da informação mediada. A dissertação destaca o resultado de toda a investigação e conclui que as novas tecnologias e as formas interativas de aprendizagem ainda não são aceitos pela comunidade escolar, como importantes recursos auxiliares. Os programas TV Escola e Proinfo deveriam revolucionar o modo de capacitação de professores e a aprendizagem dos alunos, mas não estão provocando os resultados desejados, nas escolas observadas. Os objetivos dos programas ainda não foram alcançados e o esforço dos atores governamentais e não governamentais não teve o sucesso desejado.
