    Introdução à programação usando Python
    2023-03-10 - Sobral, Sónia Rolland
    Uma linguagem de programação é um sistema que permite a interação do homem com a máquina, sendo entendida por ambos. É uma linguagem formal que especifica um conjunto de instruções e de regras, sendo usada para materializar a solução de um problema. Resolver problemas com utilização de linguagens de programação não se resume a «teclar código», escrevendo-o num editor. Antes de codificar é necessário identificar o problema, compreendê-lo e encontrar, não apenas soluções, mas a melhor das soluções. [...]

    Why ChatGPT isn't introductory programming Freshmen's best friend
    2024-06-25 - Sobral, Sónia Rolland
    The emergence of ChatGPT brought a lot of controversy in society and academia due to the ease with which students can effortlessly perform work. This paper investigates whether a freshman student in an introductory programming unit using Python benefits from using ChatGPT, even as an aid. The methodology used was the application of three written tests of one semester - using Python programming language -, answered by ChatGPT (free version), analysed, and compared with a “good” solution of each one. Strangely, or maybe not, errors and problems were found in the solutions provided by ChatGPT that are the same ones that self-taught student (those who learn on YouTube and websites around the Internet world) make.

    The first programming language and freshman year in computer science: characterization and tips for better decision making
    2020 - Sobral, Sónia Rolland
    The ability to program is the “visible” competency to acquire in an introductory unit in computer science. However, before a student is able to write a program, he needs to understand the problem: before formalizing, the student must have to (be able) to think, (be able) to solve and (be able) to define. At an early stage of learning there are no significant differences between programming languages. The discussion of the early programming language continues: probably never will be a consensus among academics. The Association for Computing Machinery (ACM) and Institute of Electrical and Electronics Engineers (IEEE) computer science curriculum recommendations haven’t clearly defined which programming language to adopt: it is the course directors and teachers who must make this choice, consciously and not only following the trends. This article presents a set of items that should be considered when you make a programming language choice for the first programming unit in higher education computer science courses.

    2024-06-25 - Santos-Pereira, Carla; Durão, Natércia; Sobral, Sónia Rolland; Moreira, Fernando
    Evaluating the progress of an Informatics Engineering degree is crucial for assessing its effectiveness, identifying areas that require improvement, and ensuring continuous program enhancement. Through systematic evaluation, it becomes possible to measure students' advancement, evaluate the quality of teaching methodologies, and align the curriculum with the evolving demands of the field. This paper presents the results from a performance evaluation of three core curricular units (1 st year, 1 st semester). The results obtained are aligned with the bibliography.

    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.

    2024-09-06 - Sobral, Sónia Rolland
    Introdução à Programação usando Python – Exercícios Resolvidos, é um complemento ao livro teórico, contendo, resolvidos, todos os seus exercícios propostos. Poderá, contudo, ser utilizado autonomamente por todos os leitores que pretendam exercitar-se na linguagem de programação Python proporcionando-lhes a oportunidade de aplicar os conceitos de maneira prática e objetiva. A prática é uma parte fundamental do processo de aprendizagem em programação. Resolver desafios, cometer erros e encontrar soluções são etapas cruciais para desenvolver as suas competências. Com este pressuposto em mente, os exercícios deste livro foram projetados para reforçar e consolidar o corpo teórico a quem dá os primeiros passos em Python, cobrindo um vasto conjunto de dificuldades e contextos práticos. O pensamento computacional e a escrita de programas numa linguagem de programação são desenvolvidos com muito trabalho individual, sendo essencial que se façam muitos exercícios. Esta tarefa nem sempre é fácil, mas necessita de ser desenvolvida e exercitada, por isso, este livro, concebido para quem parte do zero, será um excelente auxiliar na resolução de exercícios e, sobretudo, para que consiga verificar se está a seguir pelo caminho correto no percurso que o levará a tornar-se num programador eficaz e eficiente em Python.

    Erasmus country ranking: towards quality student mobility
    2020-09 - Sobral, Sónia Rolland
    Erasmus is a European Commission program which has been a huge success: more and more higher education students decide to move to one of the 34 countries that belong to the program. This article begins by analysing the reasons behind why students take a semester at another university in another country, and what the motivations for their choices are. The literature review reveals that there are personal, destination and academic reasons. Students who decide to make Erasmus mobility do not know how to choose the higher education institution where they will do said mobility. This article aims to help these students by ranking Erasmus mobility countries following the reasons that are identified in the literature as the most important. To rank Erasmus mobility countries, we use two criteria: destination and academic. The destination was subdivided into 7 items: Adventure, Cultural and Heritage, Safe and Secure, Cost of Living, Geographic Localization, Weather, Language and Sustainable. The academic part was divided into 3 items: research, university quality and sustainable. For each of the items we use the strongest and most reliable indicators. We also compare our ranking with the real number of student mobility for each of the 34 countries.

    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.

    Proposta de um modelo blended mobile learning orientado ao contexto.
    2010 - Sobral, Sónia Rolland; Ferreira, Maria João; Moreira, Fernando
    O aumento constante do número de dispositivos móveis no dia-a-dia da população, em especial junto das camadas mais jovens, leva ao aparecimento de novos paradigmas nas mais diversas áreas de actividade nomeadamente na educação. Como exemplo de um novo paradigma no processo ensino/aprendizagem poderemos invocar o m-learning (mobile learning) que tal como as tecnologias não pararam e evoluiu para o modelo Blended Mobile Learning (BML). Neste artigo é proposto um modelo BML orientado ao contexto, que assenta na utilização de software open source, para o LMS, para o mLMS e para uma ferramenta ligada à programação. O contexto de aprendizagem como factor é um dos aspectos de relevância no modelo devido às condicionantes técnicas e económicas que envolve o BML.
