In 2020, the COVID-19 pandemic led to the closure or shutdown of in-person activities in schools, universities, and research institutes worldwide. This process is analyzed and reflected upon using the complex thinking approach and the theoretical-conceptual and methodological contributions of Carlos Scolari. The results suggest the compatibility of complexity fundamentals and the adaptation of digital interfaces based on a socio-historical context and moment. This approach allows for an understanding of what occurred during the pandemic and prepares for future challenges in higher education and possible lockdowns due to the uncertainties facing contemporary society.

Many European governments, including Norway, have ambitious educational policies regarding digitalisation. Many businesses and policymakers pay great attention to the use of digital technologies in education in order to meet the future demands for a competent and qualified workforce. Among researchers and policymakers, there is a general consensus that the professional teacher is a key figure for the successful implementation of digital technologies in schools. Many expectations have been placed upon professional teachers regarding the implementation and use of digital technologies. The professional teacher is, to a certain degree, supposed to independently decide how digital technologies should be used in the classroom. This paper discusses what the concept of a 'professional digitally competent teacher' may mean in the context of schools. It also argues the need for a greater understanding of professional digital competence, one which takes into consideration various social and cultural aspects with regard to technology, schools and the teaching profession. In unpacking the social and cultural conditions for implementing technology in a professional teaching context, I will draw on concepts from the constructivist understanding of technology, namely, the 'domestication of technology'.

Introduction. Online education has grown exponentially in recent years worldwide, and Colombia has not been an exception. Objective. Describe the perceptions of students about the factors that affect the acceptance of online learning tools in Medellín. Materials and methods. A quantitative design by the use of self-managed questionnaires for 1032 students was used. Results. New information and communications technologies, faster transactions and exchanges and many other conditions have affected massification and flexibility strategies in some higher education institutions. Conclusions. The conclusion was that, even though online platforms help students feel more efficient in their learning processes, there are still many challenges to be faced concerning the implementation of new technologies as strategies to mediate in the teaching-learning process.

Wastewater treatment systems are essential in the control of environmental pollution. Developments in this regard have been directed towards an optimization technology which emulates processes that occur daily in nature. Within these systems are digesters that treat wastewater from anaerobic organic degradation processes of various kinds, making possible to achieve a complete stabilization of waste material, a degree of consolidation in the treated water and the generation of products such as fuel bio-gas and fertilizers. Having recorded the construction of a "Chinese" type biodigester in a community located at Kilometer 49 of the Municipality of Alberto Adriani in Merida State, Venezuela, a standardized model for a rural digester called "COPROCTOR" was developed. This latter increases the efficiency of these systems in terms of fabrication, installation and operation, propounding the industrialization of this kind of technologies. Addressing the development of the product as a system and stemming from a comparison of existing solutions and the use of a PVC commercial profile suitable for this purpose, "COPROCTOR" with all its components was designed, including a bio-filter to increase its efficiency. This new bio-digester was tested through experiments. [ABSTRACT FROM AUTHOR]
