We are currently witnessing a moment in history in which sustainable education practices are being principally modified by the proliferation of technologies and their wider use in every level of society, which makes necessary their integration into education contexts. This is found in the crosshairs of different institutions, which propose a series of competency frameworks, such as DigCompEdu. This framework provides suggestions for the competences that educators should be trained on under pedagogic-didactic criteria. The present work intends to measure the reliability and validity of the questionnaire DigCompEdu Check-In with the participation of 2262 professors from different public Andalusian universities. The known-groups method was utilized to elucidate if the tool is able or not to discriminate different variables of interest between known groups. The study reveals that the instrument has high indices of reliability, globally, and in the different dimensions that comprise it. Furthermore, it verifies that the instrument is sufficiently robust to discriminate the subjects who are clearly differentiated by variables related with technology. Along this line, the recommendation is given to continue working on the creation of new instruments focused on the mastery of this competency.

The impact and benefit that information and communication technologies (ICT) have in the educational field require new teaching skills. This fact has been increased by the recent crisis caused by COVID-19. This study tries to investigate the level of digital teaching competence (DTC) of Higher Education teachers of Health Sciences, and its relationship with several variables. For this, it has the participation of 300 teachers from the 9 universities of Andalusia (Spain). The research is structured through a descriptive (RQ1) and inferential (RQ2) design. The answers given to the DigCompEdu Check-In questionnaire adapted to the Spanish context are analyzed. The results, which show high levels of reliability of the questionnaire (Cronbach and McDonald) and validity (CFA), indicate that the level of competence is basic-intermediate. In addition, the area in which teachers excel is digital resources. For this reason, it is proposed to structure personalized training plans and continue expanding the characteristics of this study at an international level.

“Augmented reality” (AR) is presented as technology that harmonizes, in real time and with user collaboration, digital information with physical information through different technological supports. Such are AR possibilities, that when it is incorporated into teaching, students show high satisfaction rates and positive attitudes for its use, but at the same time, a series of limitations and obstacles can be noticed. As an attempt to investigate the technical, curricular and organizational difficulties of AR incorporation in training contexts, an instrument “AR obstacle questionnaire” (CORA) was designed, which in turn was administered to a total of 264 subject experts for validation through the Delphi method, subsequently applying the “K coefficient” (K = ½ Kc (knowledge coefficient) + Ka (argumentation coefficient)), selecting those experts who obtained a ≥ 0,8 score in the coefficient. Among the results obtained in the study we manage to point out the main obstacles involving AR implementation into university education: the lack of teacher training and improvement, the few educational experiences found, lack of conceptual foundation, limited educational research and lack of institutional support.

ResumenBajo el objetivo de conocer las valoraciones que los estudiantes, que habían utilizado objetos de aprendizaje en realidad aumentada, realizaban de los mismos, se diseñó un estudio "expost-facto" en el que participaron 429 estudiantes, los cuales cursaban las asignaturas de "Tecnología Educativa" y "TIC aplicadas a la educación" del Grado de Educación Infantil y Educación Primaria de la Facultad de Ciencias de la Educación, de la Universidad de Sevilla. Para conocer las valoraciones de los sujetos, se diseñó un cuestionario "ad hoc" con construcción tipo Likert que perseguía recoger información sobre tres dimensiones: aspectos técnicos y estéticos del objeto producido en RA, facilidad de utilización, y guía elaborada para facilitar la comprensión del funcionamiento del objeto por los estudiantes. Las valoraciones positivas realizadas por parte de los estudiantes, entre otras, nos permiten señalar que estos recursos pueden ser válidos para su incorporación en los procesos de enseñanza-aprendizaje.

AbstractWith the objective of knowing the assessments that the students, who had used learning objects in augmented reality, made of them, an "ex-post-facto" study was designed in which 429 students participated in the subjects of "Educational Technology" and "ICT applied to Education" attended the Primary and Childhood Education of the Faculty of Education Sciences of the University of Seville. In order to know the assessments of the subjects, an "ad hoc" questionnaire was designed with a Likert type construction that sought to gather information on three dimensions: technical and aesthetic aspects of the object produced in RA, ease of use, and a guide developed to facilitate the understanding of the Performance of the object by students. The positive evaluations made by the students, among others, allow us to point out that these resources can be valid for their incorporation into the teaching-learning processes.
