This research aimed to evaluate the development of mental calculation in Primary Education students promoting the use of the Calculus app in a mobile learning environment. It was observed that children have and use several portable devices with internet connection demonstrating that they are familiarized with technology. Therefore, the immanent pedagogical potential in technology should be used by educational actors towards educational success promoting immersive, contextualized, and centred student learning. Action research was elected as our methodology with planned classroom sessions for the development of mental calculation. It was found that the use of technological resources served educational intentions presenting advantages regarding motivation, feedback, time, concentration, pedagogical differentiation, evaluation, and productivity. This initiative, although not without difficulties, demonstrates that the School must assume its role of mediation of the use of technological resources for the development of school skills.

Neste artigo propomo-nos descrever a metodologia usada na análise de comunidades virtuais na rede. Dada a existência de Grupos, Redes, Coletivos e Comunidades que povoam a Rede global, importa refletir acerca do quadro metodológico a aplicar sempre que se persiga a intenção de investigar em particular uma destas entidades. Com o objetivo de analisar e caraterizar sete comunidades online, procurando evidenciar os traços que tipificam eventuais comunidades virtuais de prática, foi realizado um estudo de casos múltiplos, de natureza predominantemente qualitativa. Metodologicamente privilegiou-se a observação continuada da realidade vivida nessas comunidades, a realização de entrevistas online semiestruturadas aos moderadores, a análise de redes sociais, procurando analisar as dinâmicas interrelacionais, tendo-se complementado o estudo com o recurso à aplicação de questionários online aos respetivos participantes. Este artigo, para além de procurar dar conta da metodologia usada, apresenta uma matriz de análise dos dados que permite identificar, em face de estruturas localizadas na rede, a existência de comunidades virtuais de prática e a abrangência dos traços que as tipificam.

In this article, we propose to describe the methodology used in the analysis of virtual communities on the Internet. Given the existence of the Groups, Networks, Collectives and Communities that populate the Web, it is important to reflect on the methodological framework to be applied when pursuing the investigation of one of these particular entities. With the objective of analyzing and characterizing seven online communities and in seeking to show the traits that typify possible virtual communities of practice, a predominantly qualitative study of multiple cases was conducted. The methodology favored the continued observation of the lived reality in these communities, the conducting of moderated semi-structured online interviews, the analysis of social networks and the attempt to analyze inter-personal dynamics; while the study was supplemented by the application of online questionnaires to the respective participants.This article does not only intend to determine the methodology used, but it also presents a data analysis matrix which allows to identify, in the face of structures located in the network, the existence of virtual communities of practice and the reach of the features that typify them.Keywords: methodology; evaluation matrix; case studies; online investigation; virtual communities of practice.

This investigation relates to the professional development of in-service teachers on online teaching in K-12/P-12 schools during the COVID-19 pandemic. The main questions concerned the autonomy and support from/in schools, alternatives found and implemented. A model was developed and applied in different institutions. This article will focus on analysing the results of one Portuguese school.The study follows a Design-Based-Research methodology. The results revealed teachers have knowledge gaps regarding intermediate/advanced digital skills. Through the training course, teachers’ awareness was raised about the distinction between Remote Education and Distance Learning and some skills inherent to online teaching were developed.
