Publication Open Access Estratégias na aprendizagem da programação: como o LMS se pode tornar útil.2008 - Pimenta, Pedro Cravo; Sobral, Sónia RollandO insucesso do ensino introdutório de programação nos anos iniciais de 1º ciclo da área de Informática causa muitas vezes abandono escolar e desmotivação nos estudantes. O b-learning num ambiente construtivista apresenta-se como uma possibilidade de solução para este grave problema. A investigação apresentada usou a plataforma MOODLE e decorreu em dois anos lectivos sucessivos. Teve como base a unidade curricular semestral de Algoritmia comum ao 1º ano das três Lic.s em Informática ministradas na Universidade Portucalense. No 1º ano de investigação o uso do MOODLE estava acessível aos vinte e quatro alunos de uma das turmas práticas, sendo de noventa e dois o total de alunos inscritos. No 2º ano, que se realizou no paradigma de Bolonha, permitiu-se a inscrição na e-unidade curricular a todos os noventa e três alunos inscritos, tendo sido usada por setenta e cinco deles. A grande questão é “Será que o b-learning ajuda a melhorar as taxas de aprovação numa u.c. de Algoritmia (Alg.)?”. Outros factores foram também estudados, tais como verificar se existem características nos alunos que influenciam o sucesso na u.c. de Alg. quando complementada com uma ferramenta como o MOODLE. Estudar se há uma relação directa entre a presença dos alunos na e-u.c. (a quantidade de acessos, posts inseridos e posts certos) e o seu resultado final. E também se há uma relação directa entre a presença dos alunos nas aulas e o seu resultado final. Desenvolveram-se múltiplas estratégias para complemento das aulas presenciais, tendo-se retirado várias lições para alunos, docentes e instituições. Concluiu-se que a utilização da aprendizagem mista foi muito eficaz quer objectivamente em relação ao insucesso quer subjectivamente em relação ao nível de satisfação por parte dos alunos envolvidos, sobretudo se sabendo que a presença na e-u.c. ou qualquer actividade no MOODLE não era considerada na fórmula de avaliação final da unidade curricular.Publication Open Access Outra Verónica decide morrer2019-06-01 - Sobral, Sónia RollandPublication Open Access Introduction to programming for university freshmen: difficulties and (attempts) to solve2020-10 - Sobral, Sónia RollandLearning how to program efficiently is a task that provides enormous pleasure or, on the contrary, is an enormous frustration. [...]Publication Open Access Technology and the youth of the generation z: A case study of college students at a law school2016 - Sobral, Sónia RollandThis article belongs to a study to portray the university students of the generation Z, particularly those who did not follow technological courses. The widespread idea que these young people are experts in technology may not be correct. Digital natives live surrounded by technology, use technology to communicate and to have fun, but many of them show a lack of knowledge of some tools, including MsOffice. These tools prove to be essential during their academic life and their future working life. This article presents results from two surveys: the initial investigation on computer equipment possessed, social networks used, kind of applications access, knowledge of MsOffice tools; the second survey on MsOffice tools, was completed at the end of the course, in which were not taught but were necessary for the final work preparation and presentation. In Portugal there is a curriculum in secondary education but not all students were included. What we want is to know the knowledge that students have when they go to university and the knowledge they need to have to go to the labor market.Publication Open Access A Blended Mobile Learning Model-Context Oriented (BML-CO).2010 - Ferreira, Maria João; Sobral, Sónia Rolland; Moreira, FernandoThe steady increase in the number of mobile devices nowadays, particularly among younger people, leads to the emergence of new paradigms in several areas of activity including education. As an example of a new paradigm in the teaching / learning we could refer the m-learning (mobile learning) that, just as technology, has continued and evolved into the Blended Mobile Learning (BML) model. In this paper we propose a BML context oriented model that relies on the use of open source software for the LMS, mLMS and a tool related to the programming environment. The learning context is a relevant aspect of the proposed model by the technical and economic constraints that BML involves.Publication Open Access Sistema para ajuda multicritério ao planeamento de redes de distribuição1997 - Sobral, Sónia RollandO planeamento de redes de distribuição encontra o seu ponto-chave essencialmente na tomada de decisões sobre a construção e localização de novas subestações e ramos, por forma a satisfazer os consumos de electricidade. Particularmente equacionados deverão, neste caso, ser problemas como as restrições técnicas e os diferentes objectivos, nomeadamente económicos, de segurança e qualidade de fornecimento. O objectivo da presente dissertação é a construção de um sistema de ajuda à decisão para apoio a planeadores de redes de distribuição, em relação a um conjunto de planos de expansão e caracterizados por vários atributos (custo, robustez, fiabilidade, etc.). Os planos de expansão são pré- definidos, não sendo englobados no âmbito desta tese, constituindo trabalho de engenheiros de planeamento. Efectua-se uma abordagem a várias técnicas e métodos de ajuda à decisão, sendo incorporados no sistema aqueles que nele se mostraram manifestamente incorporáveis, por lhe proporcionarem um contributo relevante, nomeadamente técnicas de análise preliminar e os métodos baseados em relações de subordinação, Electre I, Electre IV e Promethée. Pretendeu-se, também, que o referido sistema pudesse ser utilizável por um Agente de Decisão desconhecedor das técnicas e métodos de ajuda à decisão utilizados. Formularam-se, correspondentemente, algoritmos destinados a facilitar a aquisição dos diversos parâmetros necessários ao funcionamento dos métodos em questão. Para aquisição de pesos dos critérios, definiu-se um processo de julgamentos par-a-par baseado no método AHP; unificaram-se os diferentes limiares necessários para a execução dos métodos; com vista à aquisição dos diversos limiares, foi elaborado um algoritmo fundamentado em pedidos de sensibilidades para diferenças. Os resultados dos métodos foram intencionalmente apresentados de forma a que se tornem úteis a qualquer Agente de Decisão. Os interfaces e os modos de movimentação no sistema foram particularmente cuidados, por forma a facilitar o seu uso - afinal, a familiarizar com eles e agradar a quem necessite tirar deles partido. Apresenta-se um exemplo ilustrativo do protótipo desenvolvido, no qual se simula-se a acção do Agente de Decisão recorrendo-se ás várias técnicas disponibilizadas. Planning of electric distribution nets mainly finds its key point in taking decisions about the building and location of new substation and branches, so satisfying the electricity consumption. Problems as the ones connected with technical restrictions and different aims - namely of economic security and supply-quality order - should be herein particularly studied. The aim of this particular Thesis consists in the building of a support decision system for distribution net planner's support, regarding various expansion plans and characterised by several attributes (cost, strength, liability, a.s.o.). The expansion plans are fore-definite, and therefor not included in this thesis' contempt; they belong, in fact, to planning engineering's work. An approach to several techniques and methods of support decision is presented by incorporating in the system itself those who have shown themselves clearly able to fit in it due to their relevant contribution - mainly technical and preliminary analytic, and the based upon underrating solutions, Electre I, Electe IV and Promethée - to its operation. We have also meant that the above mentioned system was able to be used by a planner that would unknown any of the shown support decision techniques or methods; in pursuit of such aim, several algorithms, intended to easiest acquisition of the several extents, have been calculated. To acquire all criteria's evaluations, a pair-to-pair judgement process, based on AHP method has been defined; aiming the knowledge of the several limits involved, the system will ask for sensitivities concerning differences between values. The results of these methods' applications were intentionally presented in such way they should be able to be useful to any Deciding Agent. All the interfaces and ways of handling have been especially cared of, so that system using - namely by any possible user, even a not professional one - might be as lightened as possible. A case study regarding the developed prototype, in which the actions of the Planner are simulated by using the several disposable techniques, is presented.Publication Open Access Web X.0 tools in teaching-learning: Implementation and evaluation of model validation.2015 - Peixoto, Nuno; Sobral, Sónia RollandWith the massification use of the Internet and its Web X.0 tools, teaching methodologies need to adapt to this new reality. Current student’s belongs to the new information society, dominated by digital technologies, need to be constantly connected to the world's largest information network, inside and outside of the learning context. This forces teachers to create more attractive and exciting methodologies so that students will be motivated and willing to learn. With this article we intend to put into practice a model validation web X.0 tools for teaching and learning, analyzed, designed and developed by the authors in previous investigations. The implementation and evaluation of the model was based on the study of two separate cases, both performed by the author. In the first study, the target population consisted of 22 graduates of a modality of education and training for active life. In this study the reference training was in the area of education and training of computer sciences, with the process of education and training for installation and operation of computer systems, Level 2. The unit training that allowed to evaluate the model was computer architecture with a duration of 50h. The second case study had the participation of 20 trainees from one modality of education and training for active life, whose reference training is in the area of education and training of trade. In this study, the process of education and training of technical / commercial Level 4. And the training unit that allowed us to assess the model was the English language with a duration of 50h. The purpose of the two case studies was to use a different methodology, never before used by trainers using web tools X.0 previously assessed by the model for the transmission of the content of the training reference. The methodological approach used in this research is characterized by an explanatory purpose of the case study, with data collection procedures performed through two questionnaires. An initial questionnaire assessing knowledge and another Final evaluation of satisfaction, and the sources of information was quantitative. As a final analysis of two case studies it is concluded that trainees positively rate experience and they learned the content more enjoyable way. Regarding the purpose of the study, it was found that the transmission of content implied a greater effort of the trainers, as they had to restructure sessions depending on the Web X.0 tools used. However, every effort was rewarded as the learning outcomes were great. Noted a greater commitment and motivation among learners, reaching these better results in the evaluation. The tools choice occurred through the appropriate model are reflected in the final for the satisfaction of trainees and their positive results. This study proved to be a contribution to the use of the model choosing the web X.0 tool for transmitting syllabus traditionally complicated modules to assimilate and understand, as has been the case with hardware and Business English. As future implications for learning, we suggest the use of the model in other modular activities as a way of consolidating the study and allow the teacher to assess the degree of functionality of web tools X.0. Since many times these same tools are used by students outside the classroom context, enabling the use of them in learning a more efficient and enjoyable way for students.Publication Open Access Is pair programing in Higher Education a good strategy?2020-12 - Sobral, Sónia RollandPair programming is by definition two-person programming on the same computer. The technique has been used in many higher education institutions and has been reported in some scientific articles, usually for introductory to programming courses. The aim of this article is to make a situation report analyzing the scientific production on pair programming for curricular units of introduction to programming in higher education, measuring the advantages and disadvantages of the strategy. The sample was composed by 153 articles indexed in Elsevier’s Scopus. The results obtained by bibliometric analysis showed the publication rates, authors, in which journals they are published, which are the organizations and countries that publish the most, which are the most cited articles and what their purpose. The benefits reported are generally better code, improved programming and group skills, advantages for women and reducing the work of instructors. The problems are group compatibility: there are studies that randomly distribute pairs, while other use personality tests or knowledge self-assessment.Publication Open Access SCRUM: From rugby to teamwork in higher education2018 - Sobral, Sónia Rolland; Moreira, FernandoRugby is a sport admired for its particularities and teachings for life in society. Despite being a collective sport with physical contact, it has a code of ethics and a set of values that differentiate it from other sports: Respect, Integrity, Passion, Solidarity and Discipline. A Rugby player is expected to be a team worker, have courage and loyalty. It is an inclusive sport: 15 players each with specific responsibilities and different functions. There are places for everyone: the small /agile, tall, fast, strong or the combative can be a 9, 4, 15, 1 or 6 respectively. Each element has to know the rules well and do their part of the game, always following the indications of the coach. A player has to encourage team-mates: everyone has their importance in the whole. Each team wants to advance on the field and score points. One of the ways to restart the game is the scrum: can occur when a player drops the ball forward or makes a forward pass, for instance. The teams have a maximum of 30 seconds to form. After the referee's orders for "crouch, bind and set" that the ball may be introduced by the scrum half of the non-offending team on the floor by the center line until it leaves the tunnel formed by the first rows and skidded by the feet of the hooker. There are many other specifics that are important for scrum like the variation of the modality: rugby XV 8, sevens 3, training levels (some don't exist, or form with 5 or 7). The principles of rugby scrum have been used for project management, particularly in software development, which has been widely studied. The items initially intended for a project are defined but may change. The scrum team are usually 6/10 people, one is the product owner and another the scrum master. The product backlog is divided into n sprints, each containing a sprint backlog defined at the beginning of each sprint in a sprint planning meeting where the entire team must be present and where the Product Owner will be the one who prioritizes the tasks to be included in this list. There must be a Daily Scrum every day where each team member presents what has been done, possible problems and takes their commitments for the day. At the end of each sprint, a Sprint Review Meeting is held to present the implemented features, the Sprint Retrospective is updated, the Release Burndown Chart is updated and planning is started for the next sprint. As in Rugby, the teams are small, there is a commitment to the position of each in the group, the motivational factor is very important and the rules are to be met without any malicious discussion between the various elements. Each one knows that for a sprint to succeed everyone has to be able to meet the stipulated for "their position". Teamwork is often used as a form of application of knowledge and evaluation in university. There's several teaching experiences using scrum principles with clear advantages: delivery times, group motivation and commitment/accountability of each element, as well as records of work. Some of these experiences include the use of eduscrum which is an application of the methodology to the teaching. This article intends to evaluate some of these documented experiences, drawing conclusions for the success of using scrum as a basis for teamwork in units as introduction of computer programming in higher education to decrease the abandonment rate and the failure rate.Publication Restricted Access Flipped classrooms for introductory computer programming courses2020 - Sobral, Sónia RollandTeaching and learning how to program are not easy tasks. Disapproval and dropout rates are a concern for everyone concerned with the topic. Therefore, it is necessary to look for strategies that improve the motivation of students who start a programming course, also improving success rates and decreasing dropout rates. The inverted class model, or flipped classroom, has been used in several experiments, showing very good results. The objectives of this teaching-learning technique is to change the traditional order: students have contact with new subjects before the classroom, using videos, texts or other material, as well as small online tests to check their knowledge. In this way, the face-to-face classes are reserved for discussion, doubts and application of previously acquired knowledge. The purpose of this paper is to analyse the scientific production on Flipped classrooms in introductory programming courses indexed in Elsevier’s Scopus. The sample is composed by 45 articles in total. The results obtained by bibliometric analysis showed when and where those documents are published, who the authors are and what the focus of said articles is. We also analysed the most cited documents. We made a summary of the articles, namely in what refers to the sample size of the experiences, which programming language is used, in which universities the articles are made, which technology is used, as well as which methods are used in order to create inverted classes and which are the objectives and results of these experiences reported on the articles.. We managed to get a global view of the theme, getting a strong analysis for those who want to use flipped classrooms for teaching programming.
