    Strategies on Teaching Introducing to Programming in Higher Education
    2021 - Sobral, Sónia Rolland
    Teaching and learning how to program are not easy tasks: they can be very challenging. Introductory programming courses traditionally have high rates of failures and dropouts. Teachers and researchers must develop strategies to combat this problem. The purpose of this paper is to analyse the scientific production on strategies on teaching how to program in higher education in journals indexed in an international database’ indexed in Elsevier’s Scopus in the years 2000 to 2019. We provide an up-to-date review of the existing literature. To provide a comprehensive survey, we not only categorize existing strategies but also present detailed descriptions of relevant topics such as Active Learning, Pair Programming, Flipped Classroom and Project Based Learning. The sample was composed by 92 articles in total. The first results obtained by bibliometric analysis showed that publication rates increased slowly but have expanded in the last two years, in which journals the articles are published, which are the organizations and countries that publish the most and which are the most cited articles. The motivation for this study is to bear in mind the research that has been done so that it strategies can be used and experienced by teachers who teach programming to undergraduate students.

    How Does Learning Analytics Contribute to Prevent Students’ Dropout in Higher Education: A Systematic Literature Review
    2021-11-04 - Oliveira, Catarina Félix de; Sobral, Sónia Rolland; Ferreira, Maria João; Moreira, Fernando
    Retention and dropout of higher education students is a subject that must be analysed carefully. Learning analytics can be used to help prevent failure cases. The purpose of this paper is to analyse the scientific production in this area in higher education in journals indexed in Clarivate Analytics’ Web of Science and Elsevier’s Scopus. We use a bibliometric and systematic study to obtain deep knowledge of the referred scientific production. The information gathered allows us to perceive where, how, and in what ways learning analytics has been used in the latest years. By analysing studies performed all over the world, we identify what kinds of data and techniques are used to approach the subject. We propose a feature classification into several categories and subcategories, regarding student and external features. Student features can be seen as personal or academic data, while external factors include information about the university, environment, and support offered to the students. To approach the problems, authors successfully use data mining applied to the identified educational data. We also identify some other concerns, such as privacy issues, that need to be considered in the studies.

    CS1 student grade prediction: unconscious optimism vs insecurity?
    2020-07 - Sobral, Sónia Rolland
    The difficulties of many students in introductory programming courses and the consequent failure and drop out make it necessary to look for motivation strategies for them to be successful. One of the strategies that is touted in the literature is self-assessment to compromise and motivate students. As we had doubts about the possibility of this strategy, we did an experiment and asked the students to predict the grades of the two tests and the two projects during a semester. Even knowing the correction grid and exercises that involve programming languages, which shows the result to the programmer, we found that the students' forecasts were not very accurate. In the first test we found that the worst students said they were going to get reasonable grades and much better than reality, while the best students thought they had worse grades than they actually had. The other moments of evaluation did not have as severe results, but forecasts continued to be inaccurate. We did tests by gender, by age, for being a freshman or not, for having taken a computer course in high school and for previous knowledge of programming languages: none of these variables proved to be as significant as the students' grades and their corresponding insecurity-fear or optimism-unconscious.

    O uso atual das ferramentas Web X.0 no ensino.
    2012 - Peixoto, Nuno Miguel Cardoso; Sobral, Sónia Rolland
    Atualmente, os métodos de ensino usados pela maior parte dos professores estão a ficar obsoletos. Fruto da rápida evolução tecnológica à qual os estudantes hoje em dia têm acesso, as metodologias de ensino tradicional não se adequam de todo com a realidade. Muitas das ferramentas Web X.0 são utilizadas pelos alunos fora do contexto de aprendizagem, mesmo sem estes nunca terem tirado algum curso para as saberem utilizar. O incentivo e inovação das metodologias de ensino terão de passar obrigatoriamente pela utilização destas ferramentas, sendo esta uma das formas que os professores atualmente têm para captar a atenção dos seus alunos. Assim sendo, com este artigo pretende-se fazer um levantamento sobre o uso atual das ferramentas web X.0 no ensino. Utilizando o Repositório Cientifico de Acesso Aberto de Portugal – RCAAP, foram analisados todos os documentos científicos publicados entre 2010 e 2011 que se encontram armazenados nesta base de dados e que de alguma forma fazem referência à utilização das ferramentas web, permitindo desta forma aferir o que está a ser feito dentro desta área em Portugal.

    A motivação da comunidade escolar e o recurso a tecnologias de informação.
    2013 - Menezes, Natércia do Céu Andrade Pesqueira; Sobral, Sónia Rolland
    A constatação de elevados índices de insucesso nas várias disciplinas é uma realidade e, como professores, é nossa convicção que o aparecimento de novas tecnologias poderá contribuir para a criação de “novos ambientes” de trabalho que promovam a motivação e o sucesso na aprendizagem. Pretende-se, com este estudo, compreender a motivação dos alunos aquando a utilização das TIC em sala de aula e alcançar um melhor conhecimento do processo de ensino aprendizagem, no que se refere à utilização das TIC, do seu potencial papel motivador na aprendizagem em geral. Ou seja, o estudo tem como objectivo saber se a utilização das TIC em sala de aula contribui para melhorar significativamente, os índices de motivação, concentração, empenho e é facilitadora na aquisição de novos conhecimentos e competências nos alunos, assim como uma influência positiva no relacionamento entre aluno e professor. Como estudo de caso, a aplicação de um questionário aos alunos do 8º e 9º ano, pretende- se, com os resultados e conclusões apresentados, promover nos professores a consciência da sua prática pedagógica, concluir se os alunos têm papel activo e motivador na construção das aprendizagens aquando a utilização das TIC em sala de aula.

    Aferição cognitiva das ferramentas Web X.0.
    2012 - Peixoto, Nuno Miguel Cardoso; Sobral, Sónia Rolland
    As ferramentas Web 2.0 e 3.0 estão ao alcance de todos, nomeadamente ao serviço do ensino. Mas nem sempre são usadas da melhor forma, sendo muitas das vezes uma tropia ao sucesso do ensino-aprendizagem. Este artigo pretende criar uma forma de avaliar e validar as características das ferramentas web na vertente ensino, para que possam ser reutilizá-las na aprendizagem. Foram analisadas as principais ferramentas web utilizadas pelos alunos e criada uma grelha que permitiu aferir as potencialidades cognitivas das mesmas, identificando desta forma quais as ferramentas web com maiores capacidades no domínio da aprendizagem. Web Tools 2.0 and 3.0 are available to everyone, including at the service of education. But not always used optimally, and often a tropy to the success of teaching and learning. This article aims to create a way to assess and validate the characteristics of web tools in the shed so that teaching can be reuse in learning. We analyzed the main web tools used by students and created a grid that allowed the assessment of the cognitive potential of the same, thus identifying which tools web with greater capabilities in the field of learning.

    Web X.0 tools in teaching-learning: Implementation and evaluation of model validation.
    2014 - Peixoto, Nuno; Sobral, Sónia Rolland
    With 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.
