ABSTRACT
To contain the COVID-19 pandemic, governments all over the world implemented strong lockdown measures to a large part of the population, including the closing of educational centres. Teachers were urged to transform their teaching methodology, moving from a face-to-face model to an emergency remote education (ERE) model, characterised by the use of technologies to continue with lectures and maintain the physical distance with the students. The aim of the present study was to analyse the existence of socio-digital inequalities and the educational challenges posed by the development of an ERE model, hence, contributing to the literature by proposing a systematic and holistic approach on this phenomenon. Based on the characteristics of the research problem and the objectives set, a qualitative methodology was applied. On the one hand, a semi-structured interview was conducted with 136 active teachers as the main data gathering technique. On the other hand, grounded theory was key in interpreting the results, with the aim of generating the theory in a systematic and holistic manner. It can be asserted that ERE was very useful during the lockdown of schools, and its potential to transform education was demonstrated. However, it was also shown that the development of an ERE model can cause socio-digital inequalities among students, due to the lack of access to digital devices and Internet connection, mainly due to factors, such as the socio-educational level of the family and the rural or urban context of the centre.
