Nowadays, people spend long periods on social media, ignoring the implications this carries in daily life. In this context, the concept of social media literacy, an emerging concept scarcely developed in the literature, is relevant. This study sought to analyze, descriptively, the main definitions and competences of the concept of social media literacy. The methodology included a systematic search of literature in the databases Web of Science, PubMed, and Scopus between 2010 and 2021, applying filters for English and Spanish, including only scientific articles. A total of 1093 articles were obtained. An article selection process took place, applying the inclusion and exclusion criteria, resulting in a total of 15 articles being selected. The findings indicate that the concept of social media literacy is based on media literacy to then integrate the characteristics and the implications of digital platforms. This is linked to the development of cognitive competences, where critical thinking, socio-emotional competences, and technical competences are fundamental, considering the social context. The development of socio-emotional competences stands out since social media are a frequent place of interaction between people.

Teachers’ ability to manage stress and daily challenges is crucial to their professional development and well-being. By examining how Chilean elementary school teachers perceive the growth in their resilient behavior, this study seeks to determine the predominant factors that foster resilience in these individuals. Sixty-three public school teachers participated in semi-structured interviews as part of a qualitative analysis employing deductive and inductive coding. The results show that teacher resilience is built through a complex interaction between personal, professional, and contextual factors. Among the most important factors are self-care, psychosocial support, and an institutional environment that facilitates teachers’ emotional well-being. Relationships with students and their families also support this resilience, creating an atmosphere of trust and collaboration in the classroom. The study highlights that strengthening resilience not only improves the teaching experience but also has a positive impact on students’ well-being and academic performance. Integrating self-care strategies, support networks, and family alliances in teacher training and education policies is essential to developing healthy and sustainable school environments. The study concludes by emphasizing the importance of specific training programs that give teachers effective tools to manage stress and adversity better. Although limited to elementary education in Chile, this study invites future research that expands the analysis to other education levels and cultural settings, offering a more comprehensive view of resilience in education.

Cyberbullying has progressively increased due to the massive use of the internet and social networks. Bystanders constitute the largest group, occupying a key role in the evolution of the cyberbullying situation and its consequences for the victim. Research shows different ways in which bystanders behave, suggesting different types of sub-roles associated with different study variables. The objective of this literature review is to identify and characterize the roles of bystanders in cyberbullying situations that involve adolescent students. To achieve this objective, a systematic search was carried out in the Web of Science, PubMed, and Scopus databases for articles published between 2015 and 2020, resulting in 233 articles. Articles were then selected by relevant title and summary. Subsequently, the inclusion and exclusion criteria were applied, resulting in a total of nine articles. The findings of this review allowed us to identify two to five types of bystanders, the largest type representing outsiders and the smallest type representing assistants of the aggressor. The identified types of bystanders are characterized for variables such as sex, age, previous experience, and empathy. The results are discussed considering the available theoretical and empirical evidence.

Self-efficacy, the conviction in one’s ability to succeed in particular tasks, is crucial in academic performance and professional development, especially in higher education programs. Although it has been widely studied in STEM disciplines, research on gender differences in self-efficacy in business education is scarce, especially in the Chilean context. This study aims to fill this gap by examining self-efficacy beliefs and their association with academic performance among business students at a Chilean university. Using a quantitative, cross-sectional design, data were collected from 239 students via the validated Academic Self-Efficacy Scale (ESAA). Confirmatory factor analysis confirmed the scale’s psychometric robustness in measuring situational and personal efficacy beliefs. No significant associations were found between self-efficacy and academic performance. However, gender differences emerged in personal efficacy beliefs, with men reporting higher levels than women, while no differences were found in situational efficacy. These findings reinforce the multidimensional nature of academic self-efficacy and reveal persistent gender disparities in how students perceive their individual academic capacities. This asymmetry may limit women’s engagement, confidence, and long-term professional development in male-dominated fields such as business. The results point to the need for gender-sensitive educational strategies that intentionally foster personal efficacy beliefs among female students, thereby promoting more equitable academic experiences and professional trajectories.

The Teachers’ Sense of Efficacy Scale (TSES) has demonstrated suitable levels of reliability and validity for its use on the teacher population in several countries, and it is the most used scale to assess teachers’ beliefs in their efficacy. However, few psychometric studies exist on its applicability to elementary teachers in public schools. This study analyzed the psychometric properties of the TSES in teachers who work in elementary education. The sample comprised 1,406 Chilean teachers, mainly women (77.2%), from various Chilean public and subsidized schools. The results obtained from three confirmatory factor analyses demonstrated that the model that best fit the data was bifactor exploratory structural equation modeling (B-ESEM) for 24 items, one general factor, and three residual factors. The results of the factorial invariance analysis indicate that the TSES remains stable up to the strict level of invariance for the variable sex. These results imply that the TSES can be used on Chilean teachers. The results are discussed based on the theoretical and empirical evidence available.

(1) Background: In this study, we aimed to determine differences in the levels of motor competence according to biological factors (sex, age and weight status) and sociocultural factors (socioeconomic level and belonging to an indigenous people or not) in students of the La Araucanía Region, Chile. (2) Methods: A total of 552 students in 5th and 6th grade were evaluated (49.6% girls; age M = 11.3; SD = 0.8). To assess motor competence (domains of object control and self-movement), the MOBAK 5-6 test was applied. (3) Results: In the object control dimension, significant differences were found according to sex, with the boys performing higher than the girls. According to age, schoolchildren aged 11.0 to 11.9 performed higher than those aged 10.0 to 10.9, and according to socioeconomic status, schoolchildren from schools with a higher socioeconomic status showed a higher motor performance. No significant interaction effects were found between groups. With regard to the self-movement domain, statistically significant differences were only found according to weight status, where students of normal weight presented the highest performance. No significant effects were found between any of the groups. (4) Conclusions: This study shows the importance of considering the biological and sociocultural characteristics in the development of motor competence when interpreting data or planning interventions in different settings.
