Most online teaching institutions still do not offer complete remote teaching, requiring the physical presence of the student in the evaluation process (for supervisory reasons), which could aggravate the evaluation and certification in massive open online teaching. Although, there are already e-proctoring tools (electronic proctoring) that allow this process to be carried out remotely, without requiring that physical presence. For this reason, and in order for this complete remote teaching to be extended to institutions that do not yet believe in the success of its implementation, this study, through a bibliographic study and a causal study carried out by experts in online teaching, focuses on locating the determining motivational factors when accepting and implementing this evaluation system as a method of remote supervision and tries to encourage its use through them. The list obtained consists of the following motivational factors: Quality management, available information, external conditioning, trust, perceived compatibility, perceived usefulness, attitude and intention, and the most decisive factor in this whole process is trust (which would be the extent of security and privacy that institutions have in the use of this tool).

Se analizan las posibilidades que la metodología Delphi ofrece para la investigación educativa y de la comunicación al mismo tiempo se ofrece algunas referencias históricas, se presentan cuáles son sus características fundamentales, las posibilidades y limitaciones que tiene su aplicación, las diferentes versiones existentes para su incorporación en los procesos de evaluación en investigación, y las fases operativas para su aplicación. También se estudia una de las problemáticas fundamentales que presenta esta técnica y que se refiere al proceso de selección de los expertos, respecto al cual se ofrecen algunas sugerencias y aportaciones para su una correcta identificación. Al mismo tiempo se presenta una de las estrategias más novedosas que últimamente se están utilizado para la selección de los informadores: el denominado “coeficiente de conocimiento experto”.

The scope of blockchain technology, initially associated with the cryptocurrency Bitcoin, is greater due to the multiple applications in various disciplines. Its use in accounting lies mainly in the fact that it reduces risks and the eventuality of fraud, eliminates human error, promotes efficiency, and increases transparency and reliability. This means that different economic sectors assume it as a recording and management instrument. The aim is to examine current and emerging research lines at a global level on blockchain technology for secure accounting management. The evolution of the publication of the number of articles between 2016 and 2020 was analyzed. Statistical and mathematical techniques were applied to a sample of 1130 records from the Scopus database. The data uncovered a polynomial trend in this period. The seven main lines of work were identified: blockchain, network security, information management, digital storage, edge computing, commerce, and the Internet of Things. The ten most outstanding emerging research lines are detected. This study provides the past and future thematic axes on this incipient field of knowledge, which is a tool for decision-making by academics, researchers, and directors of research investment programs.

To date, the knowledge and use of ICT (Information and Communication Technologies) has become an almost essential requirement when someone wants to find employment in our society. For this reason, this study aims to analyze the importance that students of the Faculty of Business Studies and Tourism of the University of Huelva (Spain) give to the acquisition of ICT skills for their future professional performance and the domain they have over them (achieved throughout their years of learning). This research is developed through a questionnaire completed by 90 students of the Faculty and concludes that in general they give these ICT skills the importance that they deserve and that their domain goes in parallel (except for some skills that show formative need), even being able to observe that in the majority of cases the dominion of these skills is tied to the importance that they give them.

This study reviews published scientific literature on the use of tangible technologies in childhood education, in order to (a) identify the what tangible technologies have been used, (b) recognize the educational purposes and uses these technologies of, and (c) present a synthesis of the available empirical evidence on its educational effectiveness. After systematically searching in WoS, 288 relevant articles were located and analyzed using the Science Mapping Analysis Software Tool from 1968 to 2018. Then, 29 relevant papers of the last five years were included in the review study. For each article, we analyze the purpose of the study, the type of tangible technology used, the research method applied, the sample characteristics and the main results observed. The articles reviewed suggest that the main tangible technology used in childhood education is the tablet and literacy (basic and emergent) is the area most studied with promising results.

Computational thinking and coding are key competencies in the 21st century. People with Down syndrome need to be part of this new literacy. For this reason, in this work, we present an exploratory study carried out with students with Down syndrome with cognitive ages of 3–6 years old using a tangible robot We applied the observational method during the sessions to analyze the participants’ emotional states, engagement, and comprehension of the programming sequences. Results show that people with cognitive disabilities can acquire basic programming and computational skills using tangible robots such as KIBO.
