At 21st century Computational Thinking (CT) is considered a fundamental skill that anyone should possess and develop from a young age. Serious games and more specifically educational games (EGs) are a promising means of introducing algorithmic thinking and programming concepts and engaging students through the process of learning. In this article,…

This paper focuses on the rapidly expanding field of largescale international assessment surveys and their impact on the field of adult education and learning. I take the case of OECD's survey assessing adult skills (PIAAC) and situate it within the wider context of the datification of educational policy and practice. The claims made for the…

Although there is strong evidence that massively multiplayer online games (MMOGs) constitute environments of social interactions and effective learning, we currently lack the tools for investigating the effectiveness of the social networks emerging as well as the cognitive aspects and knowledge acquisition such environments involve. Within this…

The present paper examines the difficulties Greek senior high school students identify in learning Statistics and how these difficulties are related to the course's level of difficulty. Also it examines the difficulties students identify that teachers face while teaching Statistics, their suggestions for changes and how these difficulties and…

Based on the notions of social and socio-mathematical norms we investigate how these are established during the interactions of pre-service teachers who solve mathematical problems. Norms identified in relevant studies are found in our case too; moreover, we have found norms related to particular aspects of the problems posed. Our results show…

The analysis of interaction among students is becoming very important in mathematics education, especially among the scholars who view knowledge as socially constructed and negotiated. One of the features of human interaction is the roles that people perform while interacting. Using a symbolic interactionist perspective, we analyzed the evolution…

In contrast to the traditional top-down approach, a bottom-up approach is proposed by current reform in mathematics education. According to this alternative proposal, algorithmizing is the activity in which students should be involved. What can we do when we want to enact such an algorithmizing approach in a classroom and our students have already…

Research in goal theory has often relied on the general linear model, ignoring some central assumptions of the theoretical framework under investigation. The purpose of the two studies reported here was to illustrate how the Rasch model can supplement traditional statistical analyses when evaluating the effects of goal orientations on persistence.…

The various difficulties and cognitive obstacles that students face when they are introduced to algebra are well documented and described in the relevant bibliography. If it is possible, in order to avoid these difficulties, we have adopted the functional approach widening the meaning of algebraic thinking. In this paper, which is part of wider…

This study investigates the role of basic elements of a learning context namely: the given tasks, the nature of the provided tools, and the pupils' gender in their choice of tools provided by an open problem-solving computer environment. Pupils' choice of tools is discussed through the description of an experiment involving the interaction of (30)…
