A tese desenvolvida tem como foco fornecer os meios necessários para extrair conhecimento contidos no histórico académico da instituição transformando a informação em algo simples e de fácil leitura para qualquer utilizador. Com o progresso da sociedade, as escolas recebem milhares de alunos todos os anos que terão de ser orientados e monitorizados pelos dirigentes das instituições académicas de forma a garantir programas eficientes e adequados para o progresso educacional de todos os alunos. Atribuir a um docente a responsabilidade de actuar segundo o historial académico dos seus alunos não é plausível uma vez que um aluno consegue produzir milhares de registos para análise. O paradigma de mineração de dados na educação surge com a necessidade de otimizar os recursos disponíveis expondo conclusões que não se encontram visiveis sem uma análise acentuada e cuidada. Este paradigma expõe de forma clara e sucinta os dados estatísticos analisados por computador oferecendo a possibilidade de melhorar as lacunas na qualidade de ensino das instituições. Esta dissertação detalha o desenvolvimento de uma ferramente de inteligência de negócio capaz de, através de mineração de dados, analisar e apresentar conclusões pertinentes de forma legível ao utilizador.

Planning and implementing a new assessment strategy using an e-learning platform

One of the most difficult issues of e-Learning is the students’ assessment. Being this an outstanding task regarding theoretical topics, it becomes even more challenging when the topics under evaluation are practical. ISCAP’s Information Systems Department is composed of about twenty teachers who have been for several years using an e-learning environment (at the moment Moodle 2.3) combined with traditional assessment. They are now planning and implementing a new e-learning assessment strategy. This effort was undertaken in order to evaluate a practical topic (the use of spreadsheets to solve management problems) common to shared courses of several undergraduate degree programs. The same team group is already experienced in the assessment of theoretical information systems topics using the b-learning platform. Therefore, this project works as an extension to previous experiences being the team aware of the additional difficulties due to the practical nature of the topics. This paper describes this project and presents two cycles of the action research methodology, used to conduct the research. The first cycle goal was to produce a database of questions. When it was implemented in order to be used with a pilot group of students, several problems were identified. Subsequently, the second cycle consisted in solving the identified problems preparing the database and all the players to a broader scope implementation. For each cycle, all the phases, its drawbacks and achievements are described. This paper suits all those who are or are planning to be in the process of shifting their assessment strategy from a traditional to one supported by an e-learning platform.

Students’ perceptions about assessment using an e-learning platform

ISCAP’s Information Systems Department is composed of about twenty teachers who have, for several years, been using an e-learning environment (Moodle) combined with traditional assessment. A new e-assessment strategy was implemented recently in order to evaluate a practical topic, the use of spreadsheets to solve management problems. This topic is common to several courses of different undergraduate degree programs. Being e-assessment an outstanding task regarding theoretical topics, it becomes even more challenging when the topics under evaluation are practical. In order to understand the implications of this new type of assessment from the viewpoint of the students, questionnaires and interviews were undertaken. In this paper the analysis of the questionnaires are presented and discussed.

Information professionals in business context: new professionals, old skills

This communication aims to present some reflections regarding the importance of information in organizational context, especially in business context. The ability to produce and to share expertise and knowledge among its employees is now a key factor in the success of any organization. However, it’s also true that workers are increasingly feeling that too much information can hurt their performance. The existence of skilled professionals able to organize, evaluate, select and disseminate information in organizations appears to be a prerequisite for success. The skills necessary for the formation of a professional devoted to the management of information and knowledge in the context of business organizations will be analysed. Then data collected in two focus group discussion with students from a graduate course in Business Information, from Polytechnic Institute of Porto, Portugal, a will be examined.
