- Acquisition of competencies in mathematics through gamesPublication . Ferreira, Maria Cristina; Pereira, José António; Oliveira, AmilcarThe objective of this paper is to present the fundamentals of game theory and illustrate how the theory can be applied in education of Mathematics.Literature specific applications of game theory across all levels of instructor-led education. With a game theory model, we provide a mathematical description of a social situation in which two or more individuals or players interact. We strongly suggestthat traditional teaching techniques of mathematics should be complemented with games.
- Aspetos socioeconómicos da Diabetes Mellitus em Pemba, Moçambique: estudo de casoPublication . Michal, Soares; Carapeto, CristinaIntrodução: Apesar da diabetes mellitus ser uma condição cujo tratamento, causas e consequências são bem conhecidas, a sua prevalência continua a aumentar sendo a sua incidência comparável à das epidemias. Objetivos: O principal objetivo do presente estudo foi averiguar se os portadores da DMII que recorrem ao Hospital de Pemba, Moçambique, têm condições socioeconómicas para seguir a dieta que lhes é recomendada para o controlo da sua condição. Resultados: Foram incluídos neste estudo de caso 28 pacientes sendo que se optou por um questionário de frequência alimentar e questões relacionadas com o dia-a-dia dos pacientes cujos resultados foram relacionados com a variável dependente classe social.

Additionally, it is considered that Echinolampas (Echinolampas) maxima de Loriol, 1896 is a valid species and E. (E.) barcinensis Lambert, 1907 is its junior synonym.
- Does fake news have feelings?Publication . Laroca Mendes Pinto, Herbert; Rocio, Vitor; Cunha, AntónioFake news spreads rapidly, creating issues and making detection harder. The purpose of this study is to determine if fake news contains sentiment polarity (positive or negative), identify the polarity of sentiment present in their textual content and determine whether sentiment polarity is a reliable indication of fake news. For this, we use a deep learning model called BERT (Bidirectional Encoder Representations from Transformers), trained on a sentiment polarity dataset to classify the polarity of sentiments from a dataset of true and fake news. The findings show that sentiment polarity is not a reliable single feature for recognizing false news correctly and must be combined with other parameters to improve classification accuracy.
- Education for sustainable development through e-learning in higher education: experiences from PortugalPublication . Azeiteiro, Ulisses; Nicolau, Paula Bacelar; Caetano, Fernando J. P.; Caeiro, SandraE-learning in higher education can be of great relevance in effective life-long learning education for sustainable development in a population of students who are simultaneously full time employees. The aim of this research was to assess the Education of Sustainable Development effectiveness through elearning in higher education in a case study. The expectations and experience of students who enrolled in more than one programme in environmental and/or sustainability science (bachelor, master, and doctorate), offered by Universidade Aberta, the Portuguese Distance Learning University, were analysed. The six dimensions analysed were: general expectations; learning quality; teaching resources, pedagogical tools and evaluation; acquired competences in education for sustainable development; satisfaction and interactions; and reasons to pursue enrolment in a new programme at Universidade Aberta. Data was collected using semi-structured qualitative interviews. The results showed that the surveyed students felt that they attained a high level of motivation and satisfaction, and had reached an effective learning outcome of knowledge, competences, values, attitudes and behaviour in environment and/or sustainability sciences. For these reasons they were motivated to return to Universidade Aberta and enrol for further training in the sustainability area. These results are built upon previous work developed by the authors, and allow us to conclude that formal e-learning programmes can provide an effective alternative to face-to-face training, allowing students to pursue their studies, in a flexible, collaborative and interactive way, whilst holding down full time jobs. In this way, Education for Sustainable Development in an e-learning regime can contribute to, and have a role in, the transition to sustainable societal patterns.
- Endless horizons?: addressing current concerns about learning analyticsPublication . Conde, Miguel A.; Hernández-Garcia, Ángel; Oliveira, AmilcarA few years after the emergence of learning analytics as a relevant topic in educational research, which has been accompanied by several publications devoted to the theme, we still see how the different topics seem to alternate both converging and diverging trends. Thus, whereas sometimes different approaches seem to converge into the study of the same issue or situation, other times the same approaches are applied to solve different problems in a divergent way. This situation becomes more complex with the added inclusion of new technological advances and analysis techniques, as a result of which the extension of the scope of learning analytics as a discipline may be perceived as endless or boundless. This is an introduction to the Track on Learning Analytics within the Technological Ecosystems for Enhancing Multiculturality 2015 Conference, which aims to address some of the current concerns on learning analytics and help clearing the horizon. This introductory paper provides an overview of the rationale of the track's proposal, including different topics open for discussion; the introduction is followed by an insight of the submission management and participants' selection process. Then, a detailed summary of the manuscripts accepted for participation in the conference is presented.
- Hybrid teaching and learning in higher education: a systematic literature reviewPublication . Gudoniene, Daina; Staneviciene, Evelina; Dieng, Djibril; Degroote, Joël; Butkiene, Rita; Huet, Isabel; Dickel, Jochen; Rocio, Vitor; Casanova, DiogoHybrid teaching, which integrates traditional in-person learning based on students’ perspectives where online learning offers a flexible approach to education, combines the benefits of technology with face-to-face interactions. Moreover, teaching and learning in a hybrid way met several challenges for both teachers and learners, including technological problems, time management, communication difficulties, and assessment complexities. This systematic review investigates six main research questions: (1) What pedagogical frameworks are used in hybrid teaching and learning? (2) How can we enhance students’ engagement in hybrid teaching and learning? (3) What is the impact of technological integration on hybrid learning scenarios, both for students and teachers? (4) How do training and support measures influence the willingness and ability of university teachers to implement hybrid teaching formats? (5) How do formative assessment and feedback methods in hybrid learning environments enable teachers to effectively monitor student progress and provide tailored support? (6) How does the implementation of hybrid learning affect student learning outcomes? This study identifies the following key themes: technological integration, pedagogical innovation, faculty support, student engagement, assessment practices, and learning outcomes. Our contribution of this literature review is related to teaching and learning by showing teachers the most appropriate way to avoid the challenges encountered when teaching in a hybrid way. These include strong technology integration, innovative pedagogical strategies, strong academic development and support, active student engagement, effective assessment practices, and positive learning outcomes.
- iMOOC on climate change: evaluation of a massive open online learning pilot experiencePublication . Coelho, José; Teixeira, António; Nicolau, Paula Bacelar; Caeiro, Sandra; Rocio, VitorMOOCs are a recent phenomenon, although given its impact, have been subject to a large debate. Several questions have been raised by researchers and educators alike as regarding its sustainability both economical and as an efficient mode of education provision. In this paper we contribute to this discussion by presenting a case study, a Portuguese MOOC about lived experiences in climate change which piloted the iMOOC pedagogical model developed at Universidade Aberta. The iMOOC is an hybrid model which incorporates elements from existing MOOCs but adds other features drawn from UAb's experience with online learning and aim at better integrate in the larger context of the institutional pedagogical culture. The iMOOC implied also an integration of platforms - Moodle and Elgg. The course had more than one thousand participants, and it was the largest MOOC course on Portuguese language delivered so far. We discuss the effort required to design and deliver the course, the technological solution developed, and the results obtained. We registered a moderate effort to create and run the course, ensured by internal staff from the University. The technological solution was a success, an integrated architecture combining well-established, well-tested open software. The completion rate was 3.3%, but the high success of this innovative learning experience is demonstrated by the active involvement of participants, almost 50% of the ones that followed the course until the end, and the satisfaction survey results, with 90% of approval. Lessons learned from this experience and future research on the field are also discussed.

- Perceptions of the students’ learning and evaluation process in an e-learning course in food preservation technology: a study case in a food consumption mscPublication . Fernandes, Tiago; Caetano, Fernando J. P.Food Preservation Technology is a main module within a course integrated in a Master of Science program in Food Consumption at Universidade Aberta, Portugal. The pedagogical model adopted at Universidade Aberta encourages open practices such as teamwork and participation at the forums for learning exchange. E-learning and b-learning tools are increasingly used in the actual global world, providing the students with a great opportunity to study from distance and submit their digital works or assignments for evaluation. However, in this case the distinctive evaluation of each student and classification with the respective grade may seem to be a significant problem for the teachers. During this module for each assignment topic, every student chose a different subject related to their professional or academic interests. This gives the student a chance to improve scientific knowledge within each topic and to further explore the proposed subject. Herein we have analysed how the different assignments that students completed within this module can reflect students’ commitment to study and actively seek for their own knowledge. Besides, the following points were also taken into consideration: (1) the difficulties that a teacher might have when evaluating students’ submitted assignments; (2) the tools that the teacher has to differentiate the quality of different assignments; as well as (3) the description of how grades can be differentiated between the students. The assignments were both teamwork and individual work that resulted from previous learning activities. In this paper, we have thus tried to understand the main limitations that students have to overcome while working on the evaluation assignments. The analytical data retrieved from the assignment’s forums reveal that only a very small part of information exchanged has a constructive nature and adds value to the work to be done. From the analysed data of the works presented by the students, it is evident that they did not use an accurate bibliographical state-of-the-art list. We also debate the teamwork evaluation process within the e-learning system and its relationship with the contemporary state-of-the-art of each discussed theme, namely Drying and water activity control, Chemical preservation, Curing, Pickling, Smoking, Fermentation, Modified atmosphere, High pressure processing, Ohmic heating, Irradiation, Membrane processing, Pulsed electric fields, and Microwave processing.
