- ItemDigital Transition and Home Education: challenges and opportunities for psychological intervention(Conference INTED24, 2024-03-04) Oliveira, Francisca; Castanheira, Gabriela; Oliveira, Rui; Cunha, Luís; Costa-Lobo, CristinaThe 21st century is being marked by a series of significant changes in educational practices that are having a profound impact on psychological intervention. These changes are driving the genesis of an innovative era of personalized, digital, and accessible education. Individualization is the tendency to adapt teaching to the individual needs of students. Artificial intelligence has the potential to transform education and can be used to personalize teaching, automate routine tasks, and assess student performance. It is true that there are obvious constraints and that it is a challenge to carry out psychological intervention in a “distance” school context, Psychologists must maintain coordinated and shared planning with the other educational actors, the emphasis on preventive and multilevel interventions and management of priorities that respect their technical and scientific autonomy. The Psychologist's support is particularly important in situations that involve (i) entry into schooling (including the analysis of requests for postponement/anticipation), (ii) cycle transition, (iii) change of educational establishment; or (iv) access and entry into Higher Education, especially if we consider that after the situation of isolation at home, the return to school/higher education institution may occur through the abrupt interruption of academic activities and attendance at an educational establishment only to, months later, return to a different space and educational establishment, often unaccompanied by their colleagues and friends. It will be important, for example, to promote literacy about transition and adaptation to change; create a dedicated space, inside or outside distance learning activities, to work on this life topic with students and families who are in this situation; build and share other digital or material resources; or intervention from the areas of action already mentioned. The guiding question of this study was: What are the challenges and what are the opportunities of the digital transition for home education? The aim of this work was to investigate how the digital transition can affect home education and identify the trends and challenges of home education in the context of the digital transition. The research was carried out in four databases with combinations of the words digital transition, home education, digital technologies, curriculum, regulation, psychological intervention. We consider 25 articles published in international scientific journals between January 2007 and September 2022, two books and two documents of a normative nature, authored by the American government. All articles met the inclusion criteria. The documents were described, and the content was systematized in a meta-synthesis. The study detailed here carries out the analysis of how the adoption of digital technologies in schools and families can have an impact on the way in which home education is carried out, identifying the challenges and opportunities of this transition, such as the need for training parents and educators, the adequacy of curricula and the regulation of home education and investigates how home education is evolving in the context of the digital transition. Implications for psychological intervention are presented.
- ItemInstrumento de Pesquisa para Prevenção da Evasão nas Instituições de Ensino Superior à Distância: metodologia de construção(PUCRS - Escola de Humanidades, 2021-09-16) Costa, Oberdan Santos da; Gouveia, Luís Borges; Cunha, LuísO objetivo deste estudo é relatar as etapas de construção do instrumento de pesquisa para prevenção da evasão, nas instituições de ensino superior à distância. O instrumento foi construído com a finalidade de coletar informações sobre o apoio acadêmico, recebido pelos estudantes, às mudanças nas circunstâncias da vida do estudante durante o processo de formação, aspectos motivacionais, experiência de aprendizagem em geral e características individuais. No estudo foi adotada uma abordagem quantitativa, com base em estudos nacionais e internacionais. Os resultados apontaram 83,3% de concordância entre os juízes para os constructos da motivação, apoio (tutor, familiar e financeiro) e 100% de concordância para os constructos sexo, idade, educação anterior e situação de trabalho. Esses dados podem ser úteis aos pesquisadores e estudiosos para o alinhamento do foco e do objetivo de seus estudos. | The instrument was constructed to gather information about the academic support received by students, changes in the circumstances of the student’s life during the training process, motivational aspects, general learning experience and individual characteristics. The study adopts a quantitative approach based on national and international studies. The objective of the study is to report on the stages of construction of the research tool to prevent evasion in Higher Education Institutions at a distance. The results indicate 83.3% concordance between the judges for the motivational, support (tutor, family and financial) constructs and 100% agreement for the constructs sex, age, previous education and work situation. These may be useful to researchers and scholars for aligning the focus and purpose of their studies. | El instrumento fue construído con el fin de recoger informaciones sobre el apoyo académico recibido por los estudiantes, los cambios en las circunstancias de la vida del estudiante durante el proceso de formación, aspectos motivacionales, experiencia de aprendizaje en general y características individuales.

- ItemSiamese Autoencoder Architecture for the Imputation of Data Missing Not at Random(Journal of Computational Science, 2024-06) Pereira, Ricardo Cardoso; Abreu, Pedro Henriques; Rodrigues, Pedro PereiraMissing data is an issue that can negatively impact any task performed with the available data and it is often found in real-world domains such as healthcare. One of the most common strategies to address this issue is to perform imputation, where the missing values are replaced by estimates. Several approaches based on statistics and machine learning techniques have been proposed for this purpose, including deep learning architectures such as generative adversarial networks and autoencoders. In this work, we propose a novel siamese neural network suitable for missing data imputation, which we call Siamese Autoencoder-based Approach for Imputation (SAEI). Besides having a deep autoencoder architecture, SAEI also has a custom loss function and triplet mining strategy that are tailored for the missing data issue. The proposed SAEI approach is compared to seven state-of-the-art imputation methods in an experimental setup that comprises 14 heterogeneous datasets of the healthcare domain injected with Missing Not At Random values at a rate between 10% and 60%. The results show that SAEI significantly outperforms all the remaining imputation methods for all experimented settings, achieving an average improvement of 35%. This work is an extension of the article Siamese Autoencoder-Based Approach for Missing Data Imputation presented at the International Conference on Computational Science 2023. It includes new experiments focused on runtime, generalization capabilities, and the impact of the imputation in classification tasks, where the results show that SAEI is the imputation method that induces the best classification results, improving the F1 scores for 50% of the used datasets.
- ItemOnline Social Networks and Workplaces: new and old challenges(European Scientific Institute, ESI, 2015-09-09) Machado, Susana Sousa; Pinto, Júlio CostaIn recent years the growth in the use of new technologies, especially the internet, has given birth to new problems that deserve to be evaluated. The use of technologies of Web 2.0 poses new challenges as to the powers of employers in using the information disclosed by the employees. The new web phase in which we live today offered an active role to the user, removing him from the shade of a passive position. This mutation of borders created new interaction paradigms insofar as the notion of time and space was altered, which could lead to serious consequences as far as the utilization of online social networks is concerned as well as its impact on the employment relationship. The boundary between what may or may not be published by the employee on online social networks like facebook, twitter or blogs is not always clear. But, the employee’s privacy concerning information available in online social networks which can be used by the employer within the employment relationship, also deserves protection. In this article, we intend to analyze the characterization of online social network on the web 2.0 in order to better understand, at a second stage, the effects of its use in the working relationship.
