Teaching with Moodle in higher education

Nowadays, with the use of technology and the Internet, education is undergoing significant changes, contemplating new ways of teaching and learning. One of the widely methods of teaching used to promote knowledge, consists in the use of virtual environments available in various formats, taking as example the teaching-learning platforms, which are available online. The Internet access and use of Laptops have created the technological conditions for teachers and students can benefit from the diversity of online information, communication, collaboration and sharing with others. The integration of Internet services in the teaching practices can provide thematic, social and digital enrichment for the agents involved. In this paper we will talk about the advantages of LMS (Learning Management Systems) such as Moodle, to support the presential lectures in higher education. We also will analyse its implications for student support and online interaction, leading educational agents to a mixing of different learning environments, where they can combine face-to-face instruction with computer-mediated instruction, blended-learning, and increases the options for better quality and quantity of human interaction in a learning environment. We also will present some tools traditionally used in online assessment and that are part of the functionalities of Moodle. These tools can provide interesting alternatives to promote a more significant learning and contribute to the development of flexible and customized models of an evaluation which we want to be more efficient.

O conceito da qualidade nos produtos à base de Ginkgo biloba comercializados em Portugal

O extracto de Ginkgo biloba é o produto fitoterápico mais vendido na Europa. Em Portugal e muitos países, a maioria dos produtos à base de plantas são comercializados como suplementos alimentares, não estando garantidos, parâmetros de qualidade, segurança e eficácia. Realizouse um estudo, com recolha de informações, tendo por base uma amostra de 50 produtos à base de ginkgo. Da análise, verificou-se que 94% podiam ser encontrados à venda na internet, e desse total, 89% possuíam informação on-line quanto à composição. Apenas 40% referem a utilização do extracto padronizado de ginkgo e muitos recomendam doses superiores às referidas como terapêuticas.

Learning management systems in higher education

The use of Laptops and the Internet has produced the technological conditions for instructors and students can take advantage from the diversity of online information, communication, collaboration and sharing with others. The integration of Internet services in the teaching practices can be responsible for thematic, social and digital improvement for the agents involved. There are many benefits when we use a Learning Management Systems (LMS) such as Moodle, to support the lectures in higher education. We also will consider its implications for student support and online interaction, leading educational agents to a collaborating of different learning environments, where they can combine face-to-face instruction with computer-mediated instruction, blended-learning, and increases the possibilities for better quality and quantity of human communication in a learning background. In general components of learning management systems contain synchronous and asynchronous communication tools, management features, and assessment utilities. These assessment utilities allow lecturers to systematize basic assessment tasks. Assessments can be straightaway delivered to the student, and upon conclusion, immediately returned with grades and detailed feedback. Therefore learning management systems can also be used for assessment purposes in Higher Education.

Group decision making and Quality-of-information in e-Health systems

Knowledge is central to the modern economy and society. Indeed, the knowledge society has transformed the concept of knowledge and is more and more aware of the need to overcome the lack of knowledge when has to make options or address its problems and dilemmas. One’s knowledge is less based on exact facts and more on hypotheses, perceptions or indications. Even when we use new computational artefacts and novel methodologies for problem solving, like the use of Group Decision Support Systems (GDSSs), the question of incomplete information is in most of the situations marginalized. On the other hand, common sense tells us that when a decision is made it is impossible to have a perception of all the information involved and the nature of its intrinsic quality. Therefore, something has to be made in terms of the information available and the process of its evaluation. It is under this framework that a Multi-valued Extended Logic Programming language will be used for knowledge representation and reasoning, leading to a model that embodies the Quality-of-Information (QoI) and its quantification, along the several stages of the decision-making process. In this way, it is possible to provide a measure of the value of the QoI that supports the decision itself. This model will be here presented in the context of a GDSS for VirtualECare, a system aimed at sustaining online healthcare services.

Sistema online de resolução alternativa de conflitos com recurso à argumentação

Numa sociedade cada vez mais e mais virada para a Internet e para a procura de informação e soluções para todo e qualquer tipo de problema de forma instantânea, imediata ou mesmo urgente, a resolução de conflitos na sua forma mais comum, ou seja, no recurso judicial aos tribunais, parece começar a ser demasiado demorada e ineficaz. Neste sentido, as pessoas procuram, de uma maneira cada vez mais recorrente, alternativas para solucionar estes conflitos, de forma mais célere, sem que no entanto a avaliação da solução encontrada perca qualidade. Surgem, então, sistemas de resolução alternativa de conflitos (Alternative Dispute Resolution – ADR), ou ainda no ambiente Web (Online Dispute Resolution – ODR). As técnicas de ADR com maior destaque são a negociação, a arbitragem e a mediação. Em qualquer dos casos, facilmente podemos associar a sua eficiência e eficácia à utilização da argumentação no processo, satisfazendo as exigências dos implicados no conflito, já que é dada voz às suas perspectivas sobre o mesmo. Argumentar permite expor factos e justificações de suporte ou oposição relativamente ao conflito, enriquecendo a solução e tornando mais claro o entendimento da mesma. Neste trabalho será abordado o tema dos ADR, fazendo uma breve explicação da sua forma de utilização, suas principais técnicas (a negociação, a arbitragem e a mediação), será ainda abordada a argumentação, bem como a sua integração com os sistemas de resolução alternativa de conflitos. O modelo de argumentação de Toulmin foi objecto de análise e aplicação para a resolução do problema definido nesta dissertação, através da sua aplicação aos processos de argumentação. Será proposto um modelo suporte à resolução alternativa de conflitos, e desenvolvido um protótipo que permita a sua validação no contexto estudado.

Using test infrastructures for (remote) online evaluation of the sensitivity to SEUs of FPGAs

This paper proposes an online mechanism that can evaluate the sensitivity of single event upsets (SEUs) of field programmable gate arrays (FPGAs). The online detection mechanism cyclically reads and compares the values form the external and internal configuration memories, taking into account the mask information. This remote detection method also signals any mismatch as a result of a SEU that affects both used and not-used FPGA parts, which maximizes the monitored area. By utilizing an external, Web-accessible controller that is connected to the test infrastructure, the possibility of running the same operation in a remote manner is enabled. Moreover, the need for a local memory to store the mask values is also eliminated.

The impact of an online mathematics education project (MATACTIVA) on higher education students

The Online Mathematics Education Project (MatActiva) is an exciting new initiative which aims to support and enhance mathematics education. The project is led by the Institute of Accounting and Administration of Porto (ISCAP), part of the Polytechnic Institute of Porto (IPP). It provides innovative resources and carefully constructed materials around themes such as Elementary Mathematics, Calculus, Algebra, Statistics and Financial Mathematics to help support and inspire students and teachers of mathematics. The goal is to increase mathematical understanding, confidence and enjoyment, enrich the mathematical experience of each person, and promote creative and imaginative approaches to mathematics. Furthermore the project can be used to deliver engaging and effective mathematics instruction through the flipped classroom model. This paper also presents the findings of a large survey, whose propose was to study the student’s reaction to the project.

Implementação de alertas de interações medicamentosas na construção de uma farmácia online

Os sistemas de apoio à decisão clinica têm-se revelado essenciais no dia-a-dia da população, nomeadamente dos profissionais e dos pacientes. Estes sistemas podem ser aplicados com diferentes objetivos: como sistemas de alerta; de prevenção de doenças; sistemas para dosagem de medicação e prescrição; entre outras. Atualmente é notório o aumento de interesse por parte da população em entender e em possuir um papel ativo nas decisões médicas. Para conseguirem fazê-lo necessitam de procurar informação. O meio mais utilizado para obter essa informação é a internet, onde a informação se encontra em grande quantidade e muito dispersa. Para além da quantidade é imprescindível encontrar informação credível, para que não haja indução da pessoa em erro. Para ajudar a solucionar estes problemas surgiram os sistemas de recomendação na saúde. Estes sistemas foram idealizados para fornecer informações às quais os utilizadores podem recorrer para tomar decisões conscientes e seguras sobre a sua saúde. Também os sistemas de alerta se têm revelado importantes na área da saúde. Estes sistemas podem ser usados em diferentes contextos e sobre diferentes assuntos, como por exemplo, a alteração do estado clínico de um paciente monitorizado, em tempo real, ou em interações medicamentosas. As interações medicamentosas podem advir da automedicação do utente ou da larga quantidade de medicação que, a partir de determinada idade, os utentes ingerem. Pode ter como causa medicação que administrem regularmente, ou até mesmo diariamente, ou doenças/estados que o utente possua que, em simultâneo com determinada medicação pode causar reações adversas. Neste trabalho foi desenvolvido um protótipo de uma farmácia online (FoAM) que fornece, ao utilizador, alertas quando há possibilidade de interações. As causas de interações consideradas foram os medicamentos que o utilizador consuma e/ou doenças/estados que possua. O objetivo é alertar para o caso das causas que o utilizador possui interagirem com o(s) medicamento(s) que este deseja adquirir. Para alcançar esse objetivo foi necessário selecionar os medicamentos a disponibilizar assim como as suas interações. Essa seleção foi baseada no prontuário terapêutico 2013 disponibilizado pelo INFARMED. Depois de recolhida e analisada a informação, foi possível compreender que informações clínicas o sistema necessita para que consiga identificar os medicamentos que não são aconselháveis adquirir. Para isso, é necessário que o utilizador forneça essas informações clínicas pessoais, necessidade que vai de encontro à posição defendida por diversos autores que apontam o uso de registos eletrónicos de saúde muito benéfico para conseguir alertas mais personalizados suprindo assim as necessidades do utilizador. É também preponderante que o utilizador perceba o porquê de determinado medicamento não ser aconselhável, por isso, ao ser emitido o alerta é também apresentada a justificação do mesmo, ou seja, é disponibilizado ao utilizador qual a causa que indicou no formulário responsável pela interação.

Design a computer programming learning environment for Massive Open Online Courses

Teaching and learning computer programming is as challenging as difficult. Assessing the work of students and providing individualised feedback to all is time-consuming and error prone for teachers and frequently involves a time delay. The existent tools and specifications prove to be insufficient in complex evaluation domains where there is a greater need to practice. At the same time Massive Open Online Courses (MOOC) are appearing revealing a new way of learning, more dynamic and more accessible. However this new paradigm raises serious questions regarding the monitoring of student progress and its timely feedback. This paper provides a conceptual design model for a computer programming learning environment. This environment uses the portal interface design model gathering information from a network of services such as repositories and program evaluators. The design model includes also the integration with learning management systems, a central piece in the MOOC realm, endowing the model with characteristics such as scalability, collaboration and interoperability. This model is not limited to the domain of computer programming and can be adapted to any complex area that requires systematic evaluation with immediate feedback.

Massive Open Online Course management: learning science and engineering through peer-reviewed projects

Massive Open Online Courses (MOOC) are gaining prominence in transversal teaching-learning strategies. However, there are many issues still debated, namely assessment, recognized largely as a cornerstone in Education. The large number of students involved requires a redefinition of strategies that often use approaches based on tasks or challenging projects. In these conditions and due to this approach, assessment is made through peer-reviewed assignments and quizzes online. The peer-reviewed assignments are often based upon sample answers or topics, which guide the student in the task of evaluating peers. This chapter analyzes the grading and evaluation in MOOCs, especially in science and engineering courses, within the context of education and grading methodologies and discusses possible perspectives to pursue grading quality in massive e-learning courses.

Video lectures and online activities to engage students in a flipped classroom

In recent years there have been several proposals for alternative pedagogical practices. Most of these proposals are based in the, so called, “active learning”, in opposition to the common “passive learning”, which is centered on transmission of information inside classrooms as well as recognized as teacher-centered procedure. In an active learning pedagogical structure, students have a more participative role in the overall learning/teaching process, being encouraged to face new learning challenges like, for instance, solving problems and developing projects, in an autonomous approach trying to make them, consequently, able to build their own knowledge. The flipped or “inverted” classroom is one of these active learning pedagogical methodologies that emphasizes a learner-centered instruction. According to this approach, the first contact that students have with the content on a particular curriculum subject is not transmitted by the lecturer in the classroom, this teaching strategy requires students to assess and analyze the specific subject before attending to class, therefore the informational component from the lecture is the homework, and class time is dedicated to exercises and assignments, always with support from the instructor, who acts as a facilitator, helping students when needed and offering supplementary explanation as required. The main objective of this paper is to discuss and explore how the use of different types of instructional videos and online activities may be implemented in the flipped classroom procedure (as means of incorporating new content and teaching new competencies) and to describe students’ perceptions of this approach within a course in a Higher Education Institution (HEI), presenting some positive and negative features of this pedagogical practice.

Learning management systems usage on higher education institutions

Learning Management Systems (LMS) are used all over Higher Education Institutions (HEI) and the need to know and understand its adoption and usage arises. However, there is a lack of information about how LMSs are being used, which are the most adopted, whether there is a country adoption standard and which countries use more LMSs. A research team is developing a project that tries to fill this lack of information and provide the needed answers. With this purpose, on a first phase, it a survey was taken place. The results of this survey are presented in this paper. Another purpose of this paper is to disseminate the ongoing project.

Teaching and learning mathematics using moodle

This paper summarizes a project that is contributing to a change in the way of teaching and learning Mathematics. Mathematics is a subject of the Accounting and Administration course. In this subject we teach: Functions and Algebra. The aim is that the student understand the basic concepts and is able to apply them in other issues, when possible, establishing a bridge between the issues that they have studied and their application in Accounting. As from this year, the Accounting course falls under in Bologna Process. The teacher and the student roles have changed. The time for theoretical and practical classes has been reduced, so it was necessary to modify the way of teaching and learning. In the theoretical classes we use systems of multimedia projection to present the concepts, and in the practical classes we solve exercises. We also use the Excel and the mathematical open source software wxMaxima. To supplement our theoretical and practical classes we have developed a project called MatActiva based on the Moodle platform offered by PAOL - Projecto de Apoio Online (Online Support Project). With the creation of this new project we wanted to take advantage already obtained results with the previous experiences, giving to the students opportunities to complement their study in Mathematics. One of the great objectives is to motivate students, encourage them to overcome theirs difficulties through an auto-study giving them more confidence. In the MatActiva project the students have a big collection of information about the way of the subject works, which includes the objectives, the program, recommended bibliography, evaluation method and summaries. It works as material support for the practical and theoretical classes, the slides of the theoretical classes are available, the sheets with exercises for the students to do in the classroom and complementary exercises, as well as the exams of previous years. Students can also do diagnostic tests and evaluation tests online. Our approach is a reflexive one, based on the professional experience of the teachers that explore and incorporate new tools of Moodle with their students and coordinate the project MatActiva.
