- Impacts of young people’s behavior on the use of information and communication technologiesPublication . Silva, Osvaldo Dias Lopes da; Sousa, Áurea; Nunes, JerónimoABSTRACT: The rapid development and constant change in the use of information and communication technologies (ICT) offers young people immense opportunities, but also presents many risks. Although there are many studies that have analyzed the positive and negative effects of ICT on the development of young people, it appears that little is known about the various factors that are linked to its use, such as the behavioral and motivational characteristics of young people (Areepattamannil and Khine, 2017). One of the purposes of this study is to find out if there is a typology associated with a set of items that assess the perceptions of young people, aged between 15 and 25 years, about the use of ICT. On the other hand, it is also intended to assess the impacts of their behaviors on the use of ICT in the post pandemic period due to Covid-19, based on the emotional and behavioral dimensions associated with assertiveness.....[...].... technologies and the interpersonal behavior scale (IBS), developed by Arrindell et al. (2002). The data were analyzed using various statistical methods, among which the Categorical Principal Component Analysis (CATPCA) and the Partial Least Squares - Structural Equation Modeling (PLS SEM). Based on the CATPCA, three main components were extracted, referring, respectively, to skills in using a mobile device (C1), using e-mail and social networks (C2) and using ICT for entertainment purposes (C3). It was verified, based on the formulated research hypotheses, that the behavioral dimension and the emotional dimension, associated with the assertive behavior of young people, have significant impacts on the use of ICT. It should also be noted, using multigroup analysis, that there are statistically significant differences between the two genders only in terms of assessing the impact of the behavioral dimension regarding skills in the use of mobile devices. In summary, it was found the existence of significant positive impacts of the two dimensions associated with assertiveness, namely the behavioral and emotional aspects of young people, in the use of ICT.
- University students’ perceptions of ChatGPT: Factors that affect their behavioural intention, usage and utility perceivedPublication . Silva, Osvaldo Dias Lopes da; Nunes, Jerónimo; Sousa, ÁureaABSTRACT: ChatGPT is one of many generative artificial intelligence (AI) tools with the potential to transform education, notably by improving student engagement and making learning more personalized and interactive. However, there are concerns in the educational community about some of its disadvantages, such as its potential to be used for plagiarism and to undermine students' ability to think independently. All potential benefits and disadvantages of using ChatGPT throughout the educational community and especially among higher education students must be properly investigated so that the most appropriate measures can be taken for use. Given that young people have a strong appetite for technology innovations, it is in everyone's interest that higher education institutions and all their interlocutors implement recommendations for best practices in the use of ChatGPT. In this sense, it is essential that the main determining factors that affect behavioural intentions in relation to ChatGPT and its use are evaluated based on the perceptions of higher education students. Based on a model adapted from the Unified Theory of Acceptance and Use of Technology (UTAUT1 and UTAUT2), the factors [Performance expectancy (PE), Effort Expectancy (EE), Social Influence (SI), Facilitating Conditions (FC)] that lead university students to ChatGPT 4.0 (free version) behavioural intention (BI) and use (GPTU) were examined. ....[...].... The data were analyzed through Partial Least Square Structural Equation Modelling (PLS-SEM), and all requirements regarding reliability and validity (convergent and discriminant) were duly fulfilled for all constructs present in the model under exploration. Most hypotheses are confirmed by the significant results, being the most preponderant factors of behavioural intention (BI) to use ChatGPT in learning social influence (SI) and facilitating conditions (FC). The use of ChatGPT (GPTU) has significant impacts on perception ease to use (PEU) and perceived utility (PU). Perceived trust reveals a moderating role in the relationship between the constructs (PE, SI, FC] and behavioural intention (BI). The results obtained could help provide policymakers in Higher Education with information on the determining factors in developing effective and efficient policies to improve the use of ChatGPT in higher education in Portugal.
