- Plataformas de conteúdos e aplicações Web 2.0: impacto da sua utilização no processo ensino/aprendizagem em instituições de ensino superiorPublication . Oliveira, Lino; Moreira, FernandoTirando partido da crescente popularidade das aplicações Web 2.0, o presente trabalho pretende avaliar o impacto da utilização conjunta destas aplicações com plataformas de conteúdos no processo de ensino/aprendizagem em instituições de ensino superior.

- Aplicações da Web social como complemento da aprendizagem no ensino superior: um caso de estudoPublication . Oliveira, Lino; Moreira, FernandoA mudança de paradigma imposta pelo Processo de Bolonha, em que o aluno passa a ser responsável pela sua aprendizagem, e uma nova geração de estudantes universitários com maiores aptidões tecnológicas, representam um enorme desafio para as Instituições de Ensino Superior. A utilização no ensino, de novos conceitos da Web Social, suportados por aplicações habitualmente designadas de Web 2.0, com as quais estes novos estudantes se sentem à-vontade, poderá trazer benefícios em termos de motivação, frequência e qualidade do envolvimento nas actividades académicas. Neste artigo é apresentada uma experiência pedagógica envolvendo uma plataforma de ensino a distância e aplicações centradas na Web, cujos resultados permitem perspectivar de que a utilização conjunta deste tipo de aplicações poderão contribuir significativamente para que os alunos do ensino superior obtenham competências diferenciadas em domínios habitualmente deficitários.
- Teaching and learning with social software in higher education: content management systems integrated with Web-based applications as a key factor for successPublication . Oliveira, Lino; Moreira, FernandoThe change of paradigm imposed by the Bologna process, in which the student will be responsible for their own learning, and the presence of a new generation of students with higher technological skills, represent a huge challenge for higher education institutions. The use of new Web Social concepts in teaching process, supported by applications commonly called Web 2.0, with which these new students feel at ease, can bring benefits in terms of motivation and the frequency and quality of students' involvement in academic activities. An e-learning platform with web-based applications as a complement can significantly contribute to the development of different skills in higher education students, covering areas which are usually in deficit.
- Integration of e-learning systems with repositories of learning objectsPublication . Leal, José Paulo; Queirós, RicardoThis paper describes a communication model to integrate repositories of programming problems with other e-Learning software components. The motivation for this work comes from the EduJudge project that aims to connect an existing repository of programming problems to learning management systems. When trying to use the existing repositories of learning objects we realized that they are mainly specialized search engines and lack features for integration with other e-Learning systems. With this model we intend to clarify the main features of a programming problem repository, in order to enable the design and development of software components that use it. The two main points of this model are the definition of programming problems as learning objects and the definition of the core functions exposed by the repository. In both cases, this model follows the existing specifications of the IMS standard and proposes extensions to deal with the special requirements of automatic evaluation and grading of programming exercises. In the definition of programming problems as learning objects we introduced a new schema for meta-data. This schema is used to represent meta-data related to automatic evaluation that cannot be conveniently represented using the standard: the type of automatic evaluation; the requirements of the evaluation engine; or the roles of different assets - tests cases, program solutions, etc. In the definition of the core functions we used two different web services flavours - SOAP and REST - and described each function as an operation for each type of interface. We describe also the data types of the arguments of each operation. These data types consist mainly on learning objects and their identifications, but include also usage reports and queries using XQuery.

- Defining programming problems as learning objectsPublication . Leal, José Paulo; Queirós, RicardoStandards for learning objects focus primarily on content presentation. They were already extended to support automatic evaluation but it is limited to exercises with a predefined set of answers. The existing standards lack the metadata required by specialized evaluators to handle types of exercises with an indefinite set of solutions. To address this issue we extended existing learning object standards to the particular requirements of a specialized domain. We present a definition of programming problems as learning objects that is compatible both with Learning Management Systems and with systems performing automatic evaluation of programs. The proposed definition includes metadata that cannot be conveniently represented using existing standards, such as: the type of automatic evaluation; the requirements of the valuation engine; and the roles of different assets - tests cases, program solutions, etc. We present also the EduJudge project and its main services as a case study on the use of the proposed definition of programming problems as learning objects.
- Extending the learning object definition to represent programming problemsPublication . Leal, José Paulo; Queirós, RicardoThe present generation of eLearning platforms values the interchange of learning objects standards. Nevertheless, for specialized domains these standards are insufficient to fully describe all the assets, especially when they are used as input for other eLearning services. To address this issue we extended an existing learning objects standard to the particular requirements of a specialized domain, namely the automatic evaluation of programming problems. The focus of this paper is the definition of programming problems as learning objects. We introduce a new schema to represent metadata related to automatic evaluation that cannot be conveniently represented using existing standards, such as: the type of automatic evaluation; the requirements of the evaluation engine; or the roles of different assets - tests cases, program solutions, etc. This new schema is being used in an interoperable repository of learning objects, called crimsonHex.
- Designing a user interface for repositories of learning objectsPublication . Leal, José Paulo; Queirós, RicardoThis paper presents the design of a user interface for repositories of learning objects. It integrates several tasks, such as submission, browse, search, and comment/review of learning objects, on a single screen layout. This design is being implemented on the web front-end of crimsonHex, a repository of specialized learning objects, developed as part of the EduJudge, a European project that aims to bring automatic evaluation of programming problems to eLearning systems.
- CrimsonHex: um repositório de objectos de aprendizagemPublication . Leal, José Paulo; Queirós, RicardoEste artigo descreve o desenho e implementação de um repositório de problemas de programação denominado crimsonHex. A motivação para este trabalho surge do projecto EduJudge que tem como objectivo principal abrir o repositório de problemas de programação da Universidade de Valladolid (online-judge.uva.es) para utilizações pedagógicas no ensino secundário e superior. Este projecto integra um repositório de objectos de aprendizagem que será usado para gerir colecções de exercícios de programação e obter os exercícios adequados de acordo com um perfil de um determinado aluno. O artigo inicia com uma análise aos repositórios actuais. Seguidamente, apresenta-se a arquitectura conceptual do repositório, baseado na metáfora de um objecto de aprendizagem como um livro numa biblioteca, e cria-se uma definição de problemas de programação como objectos de aprendizagem. Posteriormente foca-se a sua arquitectura concreta, o seu modelo de comunicação e detalhes da sua implementação. O artigo termina com algumas considerações finais.
