The education sector is one of the sectors where technologies have had the greatest impact and many are the technological tools implemented in their teaching or teaching-learning process, where teachers are the most responsible for their implementation. For this reason and due to the rise of Cloud Computing in teaching, a bibliographic study is carried out through which the motivational factors that can affect teachers when accepting and deciding to insert Cloud Computing tools in teaching are obtained, and a causal study of university professors who are experts in educational technologies and technological implementation that allows confirming the relationship of these factors in this decision and classifying them by their relevance. The list obtained is made up of the following motivational factors: quality management, available information, external conditioning, trust, perceived compatibility, perceived usefulness, attitude and intention, and the most determining factor in this entire system is external conditioning, which is the influence that teachers receive from the environment to insert these tools in their teaching or teaching-learning process.

Teaching guides are mandatory for quality agencies to evaluate teaching programmes, just as institutions require teachers to comply with them. This teaching resource has been seen as a very effective tool for the information and orientation of students in university programmes. However, the reality may turn out to be different, as the current practices with these guides are often not the desirable ones, as they are not used, read and studied by students with the level of depth that teachers wish, and in some cases they may be a mere formality for students, thus losing all their potential and meaning. The communication we present aims to present the results of a teaching innovation project to break this problem by producing video guides as digital resources that are more motivating for students. In addition, to design and experiment with a new methodology for its application and analysis of these resources in teaching programmes of any kind (face-to-face, blended and online programmes) by means of multimedia annotation. In this work we present the objectives, methodologies and resources proposed in this project, as the main conclusions we have reached as it has been to check a greater participation in the understanding of the programmes by the students, as a more active and motivating methodology to work with these resources in the classroom for an online modality.

A proposal for the design of a distance learning activity on the pedagogical use of YouTube is described. For the training of 27 teachers from Mid High Education of the University of Guadalajara in collaboration with the Virtual University of Guadalajara, to deliver the course we used the Google Classroom platform and the social network Facebook. The course aims to train teachers to understand and make use of technological tools that enable distance education. The proposal describes and highlights the potential of video and pedagogical use of youtube in times of the COVID-19 pandemic as a means to strengthen distance learning. For the data analysis, the videos and final reflections of each participant were reviewed, to recognize, guidelines that emerge from the data that generate sense looking for themes that could give a clue to organize the data. The recurrent and the particular constituted elements of inquiry. When the teachers were developing the videos, they modeled the contents, taught and selected the most appropriate codes for their recipients to communicate the concepts, processes, and this somehow conditions the Learning of students. Recognizing the role of the audiovisual broadcaster has implications by recognizing them as a mediator because it is a teacher who has to appropriate the content and is in the process of appropriating the technological tools are used to communicate such content, but also, is appropriating a model of communicating the educational through audiovisual media.

This work discusses in-person to virtual teaching adaptation through an applied, collaborative learning strategy among engineering students. It details the face-to-face didactic sequence and how it adapted to online sessions. During implementation, the teacher gathered observations. Students answered a questionnaire on collaborative work, its arrangements, and the role of teacher as facilitator in the collaborative learning environment at the end of the session. The findings indicate a positive assessment of collaborative online learning and reveal the challenges that arose in adapting to this teacher-student environment.

The pandemic context in the world has implied a curricular change in higher education institutions globally, impacting the management and operationalization of teaching in an accelerated way. Given this, it’s relevant to consider the perception of university professors about the impact of the pandemic context on the didactic operation generated, because this can contribute to the understanding of the ways in which the curriculum is adapted in an artisanal way in this online modality that it has been necessary to carry out. For this study, a quantitative methodology is used, and the IOP20 questionnaire is used as a methodological data collection strategy, which establishes 4 dimensions, on which it is necessary to analyze the results. The method used to analyze the data is quantitative and descriptive, statistical methods and clustering techniques are used. With the results obtained, it is possible to clearly establish the perception of university professors in a very favorable way, about the importance of attending to what is related to didactic innovation in this teaching-learning process in the current situation.

Nowadays, Women are working in areas STEM (Science, Technology, Engineering and Mathematics), but areas as: engineering are perceived as male domains and scientist as predominantly male. The advancement of Industry 4.0 has made learning competencies in areas such as science, technology, engineering and mathematics (STEM) of great interest for technological development and innovation. Woman researchers wanting to find tools that support the teaching of programming for the female gender, the same female gender has been motivated to create different materials, from physical toys to frameworks. Therefore, the role of the woman who works in engineering is to motivate other girls to follow, to show them that any woman can access this set of competences. There is still a gender gap in learning. There are gender differences in learning and what motivates us to choose a career.

This article describes a gamified educational experience using different tools and techniques, including virtual reality and augmented reality in higher education. Gamification in education has demonstrated to be a good strategy to motivate students promoting their active participation. It is possible to introduce gamification techniques into virtual environments and in traditional classrooms. A current successful game in 2020 is Among Us, and one of the gamified activities was based on its mechanics. Besides, this work presents different gamification techniques combining different virtual environments during the remote adaptation teaching due to the pandemic.

Due to the 2020 scenario, the pandemic caused by the COVID-19 virus prompted a substantial change in the methods used by teachers when teaching and implementing their classes. As a support mechanism for teachers in the face of the radical change from physical presence to virtual presence, two courses were designed by the School of Pedagogy of the Universidad Panamericana: the first on Instructional Design and the second on didactic tools that enhance interaction and revitalization of classes. The summer of 2020 was the ideal time to train and prepare teachers in the instructional design of online classes because, although the educational model of the university is face-to-face, the circumstances and health limitations forced a strategic change to carry on with the quality that characterizes the institution. The preliminary results that we analyze with the SPSS software indicate that for 89.4% of the teachers the content of the course contributed to their professional development and that 87.9% have sufficient elements to redesign their subject for the following semester, which is executed in virtual mode.
