تعداد بازدید : ۹۵ تعداد دانلود : ۴۹
The situation generated by the pandemic has caused irreversible changes in society and the educational world, manifesting a necessary change in methodology in the teaching and learning process. The purpose of this study, which is part of a doctoral thesis investigation, was to analyze the use of Information and Communication Technologies (ICTs) and the digital competences of teachers in the Foreign Language classroom, before and during the state of alarm provoked by the pandemic Covid-19, based on sociodemographic factors. A non-experimental, ex post facto, descriptive study was carried out using a single measuring instrument. The final sample consisted of 117 foreign language teachers from bilingual schools of Primary and Secondary Education in Andalusia (Spain), both public and semi-private. The results indicate that teachers improved their digital skills as a result of the increased frequency of ICT use during the pandemic, and men under 30 years of age felt more motivated to use and incorporate new technologies in their classes. Even so, teachers continue to express the need for greater training opportunities in the use of ICTs for both educators and students, which will pose new challenges in the acquisition and development of digital competencies and from which new needs will emerge.

تعداد بازدید : ۱۰۵ تعداد دانلود : ۷۲
Following World War II, the United States constructed a liberal international order that grew noticeably more influential after the Cold War. Today, this order is in crisis, in a way that certain  International Relations theorists mention the emergence of a post-liberal international order. In this relation COVID-19, as the most severe global public health crisis, has created an unexpected and serious problem in the International order. Taking into account this new international order, this research focuses on the following questions: What kinds of order are possible and whether COVID-19 Can be considered as an opportunity that helps China to build international order as a hegemon? In answer to these questions, this paper uses a conceptual model to predict the future international order according to the factor of Covid-19 and the role of China in this order. According to the existing models and with respect to the most important challenges for China to achieve a hegemonic position, we will conclude that the future order of the international system will remain as security-based international order, with two actors (China and Us) and two different ideologies.

Objective: Capture of attention occurs when a goal-irrelevant salient stimulus appears in the field of attention. The COVID-19 pandemic seems to be salient enough to capture a great proportion of one’s attentional resources. The purpose of this study was to explore how novelty of outbreak news affects attention in everyday life. Methods: 162 participants were recruited using an online invitation and divided into two samples (early and late sections). The variables—salience of news, intrusive thoughts, endogenous attention, and knowledge of COVID-19—were compared between the two measurements using one-way MANOVA. Additionally, a correlational analysis was performed in order to reveal a model of relationships between variables. Results: It was found that despite the increase in infected cases, intrusive thoughts and attentional capture were decreased over time. To describe the relationship between salience of news and attentional capture a conceptual model was presented. Conclusion: In addition to the other physical properties of a stimulus, novelty also contributes to stimulus salience. In everyday life, novel situations can trigger intrusive thoughts and attentional capture. Nonetheless, it cannot be sustained after the novelty has worn off. The proposed model can be useful to understand further similar situations.
