Publicação Acesso Aberto Two Decades of Research in e-Learning: A Deep Bibliometric Analysis2021 - Sobral, Sónia RollandE-learning is the electronic version of distance learning: a planned teaching that presupposes a physical separation between the teacher and the student. The distance is either geographic or temporal, and communication can be asynchronous or synchronous, respectively. E-learning has been a target of high-quality research for the last two decades. The purpose of this paper is to analyze the scientific production on e-learning in journals indexed on Elsevier’s Scopus. The sample was composed by 25330 articles from 2000 to 2019. The results obtained by bibliometric analysis showed that rates publication continue to increase. A report was made on the journals, languages, authors, keywords, organizations and countries that publish in the field. This analysis was done for all articles as well as for the most cited articles. The bibliometric analysis was done for a total of 20 years, as well as for four 5-year periods. This article provides information from the past, but mostly clues about research on e-learning in the futurePublicação Acesso Aberto Bachelor's and master's degrees integrated in Portugal in the area of computing: a global vision with emphasis on programming UCS and programming languages used2018 - Sobral, Sónia RollandThe creation and maintenance of courses (1st cycle and integration 1st and 2nd cycle) in computer science is of concern to those responsible. The area is in constant development and, despite the need for very specialized technicians and almost unemployment zero, it seems that it is not in the minds of most students who finish high school. This article describes how secondary education works in Portugal, as well as the entrance to the Portuguese higher education. With this study we were able to verify which courses have the most demand and, on the other hand, those that do not constantly fill all the vacancies. In this study we verified that in the year 2016-2017 the students who intend to join the upper insino had 122 courses: 106 Lic-1º cycle, 15 Integrated Masters and 1 Preparation. In other words, the choice was made from the Area of Technologies and returned links to information about 193 courses. We extract courses in which in its denomination it had the content comput * and informát *. We also added eight that seemed relevant to us as Management and Information Systems or information technologies. The basis of our study consists of a 122 courses of 66 different intuitions. We highlight the institutions of higher education (public and private), denomination of courses and type (1st cycle, integrated masters or preparation). From these courses we verify the proofs of access are (with view to numerous clausulus). The private Universities give little information: so we put them way out; for the rest: only 59 courses filled all the vacancies. We will study these 59 courses in more detail: institutions and different names. Of these, only 46 have course unity are available on-line. We have studied in detail the curricular units of the first two semesters. We extract the number of course unit and programming languages (which are) and study those course unity contents. Of the 46 courses we presented we extracted ten, the top 10. The choice of these and not others is related to the number of places being higher than the other courses, as well as the entry notes. From this 10 courses we will study course plans, as well as giving emphasis to course unity those who use programming languages: what programming languages, paradigms, and how many are used. In this way we get an overview of the curricula of computer courses in Portugal, namely what refers to paradigms and programming languages?Publicação Acesso Aberto Model validation tools web X.0 in teaching and learning.2014 - Peixoto, Nuno; Sobral, Sónia RollandIt is important to adapt current teaching methods to the new information society and knowledge dominated by digital technologies. The so-called traditional teaching methods and teachers need to readjust to this new reality. This will necessarily be by the use of the Internet and web tools systematically manipulated by the new digital society students. With this article we intend to create a model based on validation parameters carefully selected by the authors in previous studies, which to judge the degree of functionality in the teaching- learning of the five most used web tools in Portugal. The model will allow in future research to assess the degree of functionality of web tools preferably used either by teachers or by students, enabling the use of these more efficient and profitable in the learning process of students.Publicação Acesso Aberto EU27 Higher Education Institutions and COVID-192021-06-02 - Sobral, Sónia Rolland; Cardoso, Abílio; Jesus-Silva, Natacha; Moreira, FernandoCOVID-19 forced higher education institutions to reinvent themselves. The (usually) face-to-face education has swapped to distance contingency education. This change brought about numerous challenges that impose adjustments in several dimensions, such as pedagogical strategies and the dependence on teaching platforms and computer systems—and, above all, the new relationship between the various actors (students, teachers, and management staff). All the sudden changes, combined with uncertainty concerning what was happening, created several strategies and options. This paper has the main purpose of analyzing the scientific production on higher education of EU27 academic institutions during the 2020 COVID-19 pandemic in journals indexed in Clarivate Analytics’ Web of Science and Elsevier’s Scopus. The sample is composed of 22 articles in total. The results show that the articles were published in 19 journals; their main focuses are Higher Education, COVID-19, and distance learning. In our database, we find several types of concerns, which shows that HEIs have a wide range of dimensions. We intend this article to be an instrument, not only to identify what was done in 2020, but to point out clues for the future.Publicação Acesso Aberto CS1 Student Grade Prediction: Unconscious Optimism vs Insecurity?2021 - Sobral, Sónia RollandThe 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.Publicação Acesso Aberto To do or not to do previous homework in computer education2022-06 - Sobral, Sónia RollandThe first contact of freshmen students with computer thinking and programming languages is not an easy task. [...]Publicação Acesso Aberto How Does Learning Analytics Contribute to Prevent Students’ Dropout in Higher Education: A Systematic Literature Review2021-11-04 - Oliveira, Catarina Félix de; Sobral, Sónia Rolland; Ferreira, Maria João; Moreira, FernandoRetention 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.Publicação Acesso Aberto Enhancing Higher Education in Portugal: Leveraging generative Artificial Intelligence for learning-teaching process2024-10-23 - Santos-Pereira, Carla; Ferreira, Maria João; Sobral, Sónia Rolland; Durão, Natércia; Moreira, FernandoRecent advancements in Generative Artificial Intelligence (GAI) have revolutionized numerous fields, including higher education. This study focuses on the integration of GAI in Portuguese higher education institutions and explores its multifaceted implications and potential. Our research, conducted through a comprehensive survey between April and June 2023, engages with higher education faculty to understand their perceptions and utilization of GAI tools in teaching and learning processes. The potential of GAI to enhance personalized learning and interactive teaching methodologies is significant. It enables the creation of customized educational content, interactive simulations, and real-time feedback mechanisms, thus reducing the educators' workload and enhancing the learning experience. However, this integration is not without challenges. The study identifies critical ethical concerns around the use of GAI, including data privacy, intellectual property, and the potential for bias in AI-generated content. Additionally, our findings indicate varying acceptance and readiness among educators to adopt these technologies. While some express enthusiasm for the potential of GAI to transform educational practices, others remain cautious, highlighting the need for comprehensive training and support to leverage GAI capabilities fully. This paper captures the essence of the study's findings, illustrating both the promising opportunities and the complex challenges associated with using Generative AI in higher education. Higher education institutions can significantly enhance teaching and learning landscapes by addressing these challenges and fostering an informed and ethical approach to GAI integration.Publicação Acesso Aberto Exploring the impact of Artificial Intelligence generative tools on research in Higher Education Institutions: A perspective from Portugal2024-10-23 - Sobral, Sónia Rolland; Ferreira, Maria João; Santos-Pereira, Carla; Durão, Natércia; Moreira, FernandoArtificial Intelligence (AI) generative tools have emerged as transformative instruments in various domains, including research and academia. It is important to see what is positive and what is not. This study focuses on the integration of GAI in Portuguese higher education institutions and explores its multifaceted implications and potential. Our research was conducted through a comprehensive survey between April and June 2023, garnering 77 responses. To this purpose, the analysis will have several insights into the research process, namely, to assess the frequency of use and objectives of using generative AI for higher education research and to explore possible trends and future directions in the adoption and application of generative AI in this field.Publicação Acesso Aberto Web X.0 tools in teaching-learning: Implementation and evaluation of model validation.2014 - 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.
