Sexting is a common practice among young adults that consists of sending material with sexual content to other people. During the COVID-19 pandemic containment situation, the main means of exploring sexuality have been through digital devices. Therefore, the purpose of this paper is to analyze the practice of sexting before and during confinement due to COVID-19 amongst Spanish university students. A longitudinal design was adopted from the application of an online survey based on three standardized and internationally used instruments on a sample of university students (n = 499) before and during confinement. The results indicated that the practice of sexting was slightly higher during confinement. At the same time, the use of dating applications was a conditioning factor in sexting. Furthermore, it was noted that sexting had a significant influence on college students’ levels of self-control, depression, anxiety, and stress during confinement. Finally, the main conclusions of this study are discussed where the situation of confinement has had an impact on the lives of students and their habits of digital consumption and expression of sexuality.

Gamification is being implemented in university teaching as an innovative method in the teaching-learning process in line with 20th century society and the current type of student. The purpose of this chapter was to develop the experience of teaching innovation carried out with gamification, mobile learning, and flipped classroom resources and tools for trainee teachers at a Spanish university. Specifically, the experience was aimed at making classrooms more dynamic with mobile applications for self-assessment and reinforcement of learning using mobile devices. The results showed that students increased their autonomy, the acquisition of new knowledge, improved academic performance and content retention thanks to gamification. Finally, the use of mobile devices and applications brings students closer to the social and everyday reality outside the classroom.

The importance of structural design under fire conditions, together with the uncertainty in the behavior and resistance of reinforced concrete structures with fiber-reinforced polymer bars (FRP) at high temperatures, reveal the need for more research along these lines. Although there are studies evaluating the flexural and shear strength of elements exposed to fire, there are no standards nor regulations specifying the procedures thereto. This work proposes methods to calculate shear strength in FRP-reinforced concrete beams, with rectangular cross-section, based on the degradation of the properties of the materials and/or the reduced concrete cross-section, as recommended by Diab (2014), Eurocode 2 (EN-1992-1-2, 2004) and Saafi (2002). In accordance with the thermal analysis executed with the Super Tempcalc software, these procedures were applied to 13 beams of different dimensions and reinforcements, subjected to standard fire of the ISO-834 standard on three sides, thereby obtaining the shear capacity degradation curves for each case. The results show that the EN-1992-1-2 (2004) allows to adequately predict the shear strength of RC beams with FRP under fire conditions.

The scale was composed of 16 items configured in five factors: mobile devices, digital competence, knowledge construction, cooperative work and education. Finally, the scale presented good psychometric properties, gathering a unique and reliable instrument to evaluate good teaching practices with mobile devices at the University.

This study aims to analyze and determine the factors that have an impact on the intensive use of Instagram and its relationship with smartphone addiction and self-esteem. A total of 389 Instagram users aged between 18 and 57 (M = 23.98; SD = 5.37) completed an online survey based on three standardized scales. The findings of the study suggest that there are statistically significant differences in the intensive use of Instagram and smartphone addiction, according to the individual's employment status and the level of studies completed. Furthermore, the multiple linear regression analysis established age and time spent on the social network as predictors of the intensive use of Instagram and smartphone addiction. Finally, the structural equation model showed a positive correlation between making an intensive use of Instagram and smartphone addiction, and a negative correlation between smartphone addiction and self-esteem.

Cada vez es más común ver a personas practicando deporte mientras utiliza su dispositivo móvil para medir su rendimiento o simplemente por el hecho de estar usando una app lúdica que requiere el desplazamiento. Por tanto, debido a la relevancia de la temática, en este estudio se propuso como objetivo analizar el efecto de las aplicaciones móviles en la actividad física a partir de la revisión de las investigaciones indexadas en las bases de datos Scopus y PubMed (2013-2018). La metodología utilizada ha sido una revisión sistemática con meta-análisis, poniendo el foco de interés concretamente en cinco variables de análisis en base a estudios previos: muestra, aplicación móvil, diseño metodológico, instrumentos de recogida de datos y principales hallazgos. La muestra se compuso por investigaciones de carácter empírico con mínimo de un grupo experimental y otro control (n = 18). Entre los resultados, se constata la variabilidad de apps utilizadas en la actividad física, así como el efecto estadísticamente significativo a favor del grupo experimental. Finalmente, los dispositivos móviles son un potente recurso para la mejora y aumento de la práctica deportiva, al mismo tiempo que se establecen nuevos componentes motivacionales para realizar deporte y sus implicaciones en la enseñanza de la educación física.Abstract. The use of mobile applications (apps) in sports has become common practice. It is increasingly common to see people practicing sports while using their mobile device to measure their performance or simply because they are using a playful app that requires movement. Therefore, due to the relevance of the subject, this study aimed to analyse the effect of mobile applications on physical activity from the review of the research indexed in the Scopus and PubMed databases (2013-2018). The methodology used was a systematic review with meta-analysis, placing the focus of interest specifically on five analysis variables based on previous studies: sample, mobile application, methodological design, data collection instruments, and main findings. The sample was composed of empirical research papers with at least one experimental group and another control (n = 18). Among the results, the variability of apps used in physical activity is verified, as well as the statistically significant effect in favour of the experimental group. Finally, mobile devices are a powerful resource for the improvement and increase of sports practice, while establishing new motivational components for sports and their implications in the teaching of physical education.

Este trabajo ha sido financiado por el Proyecto I+D+I Oficina de Transferencia de Resultados de Investigación (OTRI) de la Universidad de Granada (Referencia: CNT4315)., El uso del dispositivo móvil se ha multiplicado en los últimos años, formando una parte esencial de nuestro día a día. En el ámbito de la educación superior se están empezando a introducir como una herramienta más para la mejora del proceso de enseñanza-aprendizaje, denominándose con el término mobile learning. En este trabajo se ha propuesto como objetivo analizar la influencia de los dispositivos móviles en el rendimiento académico y en la autorregulación del aprendizaje. Se utilizó un método cuantitativo basado en la aplicación de un cuestionario en línea a una muestra total de 420 estudiantes del Grado en Educación Primaria de la Universidad de Granada. Entre los resultados, se constata la influencia significativa del género en el uso de los dispositivos móviles y a su vez, del uso de los dispositivos móviles en la autorregulación del aprendizaje. Sin embargo, el uso del dispositivo móvil no influyó significativamente en el rendimiento académico. En suma, los estudiantes constatan que el dispositivo móvil ayuda en su proceso de aprendizaje, puesto que facilita el acceso a la información y a los contenidos. Finalmente, la influencia que presenta el dispositivo móvil en la educación es una cuestión clave para conocer los recursos tecnológicos que realmente tienen un efecto positivo en el aprendizaje, entre los que podría estar los Smartphones y las Tablets., The use of mobile devices has multiplied in recent years, forming an essential part of our daily lives. In the field of higher education, they are beginning to be introduced as another tool for improving the teaching-learning process, known by the term mobile learning. The aim of this paper is to analyse the influence of mobile devices on academic performance and self-regulation of learning. A quantitative method was used based on the application of an online questionnaire to a total sample of 420 students of the Degree in Primary Education of the University of Granada. Among the results, the significant influence of sex in the use of mobile devices and, in turn, of the use of mobile devices in the self-regulation of learning is noted. However, the use of the mobile device did not significantly influence academic performance. In short, students find that the mobile device helps in their learning process, since it facilitates access to information and content. Finally, the influence that the mobile device has on education is a key question to know the technological resources that really have a positive effect on learning, which could include Smartphones and Tablets., Universidad de Granada (Referencia: CNT4315)

This paper has been funded by the Ministry of Education, Culture and Sport of the Government of Spain (Reference FPU16/01762)., The use of mobile learning is becoming increasingly widespread among university teachers, thanks to its many benefits. Moreover, its application is associated with good teaching practices. The aim of this study is to analyse the development of good teaching practices in the use of m-learning by university teachers from the Department of Didactics of Language and Literature, as well as to identify the factors that influence the development of best practices. The research method developed is based on a transversal design. 110 teachers from the Department of Language and Literature Didactics participated in the study. The instrument used is the scale of Analysis of M-learning practices at the University (APMU). The results show that more than half of the teachers use the teaching method based on mobile learning. It can be concluded that in the development of best practices, gender is not influential, but age and teaching experience are. In addition, personal concern and experience in the use of mobile devices by teachers is a key factor in the appropriate development of the m-learning method., A utilização da aprendizagem móvel está a tornar-se cada vez mais generalizada entre os professores universitários, graças aos seus múltiplos benefícios. Além disso, a sua aplicação está associada a boas práticas de ensino. O objectivo deste estudo é analisar o desenvolvimento de boas práticas de ensino na utilização do m-learning por professores universitários do Departamento de Didáctica da Língua e Literatura, bem como identificar os factores que influenciam o desenvolvimento de boas práticas. O método de investigação desenvolvido é baseado num desenho transversal. O estudo envolveu 110 professores do Departamento de Didáctica da Língua e Literatura. O instrumento utilizado é a Análise das práticas de M-learning na escala da Universidade (APMU). Os resultados mostram que mais de metade dos professores fazem uso do método de ensino baseado na aprendizagem móvel. Pode-se concluir que, no desenvolvimento de boas práticas, o género não é influente, algo que ocorre com a idade e a experiência de ensino. Além disso, o interesse pessoal e a experiência na utilização de dispositivos móveis pelos professores é um factor chave para o desenvolvimento adequado do método m-learning., Ministerio de Educación, Cultura y Deporte FPU16/01762

We acknowledge the researchers of the research group AREA (HUM-672), which belongs to the Ministry of Education and Science of the Junta de Andalucía and is registered in the Department of Didactics and School Organization of the Faculty of Education Sciences of the University of Granada., Currently, the e-learning method, due to the period of confinement that is occurring due to COVID-19, has increased its use and application in the teaching and learning processes. The main objective of this research is to identify the effectiveness of the e-learning method in the teaching of mathematics with adults who are in high school, in contrast to the traditional expository method. The study developed is quantitative, descriptive and correlational. The research design is quasi-experimental, with a control group and an experimental group. The results show that the use of the e-learning method has a positive influence on motivation, autonomy, participation, mathematical concepts, results and grades. It can be concluded that the e-learning method leads to improvement in adult students who are studying the mathematical subject in the educational stage of high school, provided that it is compared with the expository method. Therefore, this method is considered effective for its implementation in adults., Corporacion Escuela Tecnologica del Oriente ISPRS-2017-720, Secretariat of Education of Santander ISPRS-2017-7202, AreA HUM/672 Research Group of the University of Granada ISPRS-2017-7202

Emerging technologies such as virtual reality and mixed reality are an educational resource that attracts students' attention and increases their interest in the content presented. The application of this technology to a MOOC course makes the proposal to motivate students really interesting. This paper presents the proposal and design of a MOOC course on social entrepreneurship that integrates virtual reality and open educational resources. Furthermore, the methodology used in the course is based on the Learning Environment Modeling Language (LEML). This makes it really attractive to the public, while improving the traditional content of a training course. Finally, the main findings and implications of the training course on competence in social entrepreneurship and its relation to the development of Sustainable Development Objectives are discussed.

Public speaking anxiety (PSA) is a common phobia in the student population. Traditionally, exposure therapy has been used as a treatment. However, the use of virtual reality (VR) is increasingly common to treat PSA. The purpose of this paper was to analyze the published scientific literature on VR as a treatment for PSA in students. The articles indexed in two databases (Web of Science and Scopus) were analyzed, with a time period from the beginning of the first publications until 2019 included. The systematic literature review was based on fixed inclusion and exclusion criteria. A total of 13 studies were identified which included 481 students. The results collected indicate that the duration of treatments to have positive effects was at least one week, where the number of sessions was between one and twelve. Furthermore, most VR treatments reported positive effects. Finally, this study showed evidence that VR treatment for PSA is effective while being less invasive than in vivo exposure., Ministry of Education, Culture and Sport of the Government of Spain (Project reference: FPU16/01762).

Although the value of information and communication technology (ICT) is positive and its use is widespread, its potential as a teaching tool in mathematics is not optimized and its methodological integration is rare. In addition, the availability of ICT resources in schools is positively associated with the academic success of students, and the availability of ICT resources at home is negatively associated with their success. To determine the relationships among academic performance, uses, and available ICT resources, a total of 2018 secondary school students participated in the present study. The uses and available ICT resources, and the learning of mathematics and ICT, were evaluated using a validated 11-item questionnaire. Statistical analysis reveals that, of the secondary education levels, the lowest results are observed in the third year. A total of 64% of students affirm that they use ICT at home to study mathematics. In addition, 33.61% of the students affirm that they use their mobile phones frequently while studying at home. However, it should be noted that between 23.80% and 28.44% affirm that they dedicate more than 4 h per day to phone calls. Educational level is a predictor of academic performance in mathematics associated with students&rsquo, uses of ICT. The scores indicate that the computer is generally used for Internet searches, thus, limiting the use of ICT for educational purposes. Furthermore, there is a difference regarding gender.

Mobile devices are a revolutionary element that offer many possibilities, although they can also cause problems for users. This is the case with the development of addictive behaviors that can affect personal well-being. The purpose of this paper has been to analyze the influence of smartphone addiction and Instagram use intensity on the self-esteem of Physical Education students. A cross-sectional research design was adopted by applying an online survey to a sample of undergraduate students (n = 385). The results showed that gender and age were factors that influenced the problematic use of the smartphone. In turn, there was a significant positive correlation between smartphone addiction and Instagram use intensity. The influence of smartphone addiction on students’ self-esteem was also highlighted. In contrast, Instagram use intensity did not affect self-esteem. Finally, the findings are discussed, and the main implications of the study are established, where physical education students take on a special role in order to avoid the improper use of smartphones and Instagram through sport., University of Granada (Spain) PPJIB2019-06
