Article
In this paper, we present the first meta-analysis of the effectiveness of game-based interventions in reducing students’ levels of maths anxiety. After searching for randomised studies relevant to game-based intervention for maths anxiety, 22 effect sizes with 913 participants described in 15 peer-review articles met the selection criteria. A rando...
Article
Several studies suggest the need to develop technology skills from a young age. The development of computational thinking enhances multidisciplinary abilities, such as abstracting and decomposing a problem into smaller parts to find a solution. Among various tools, educational games can be implemented to efficiently stimulate the development of tec...

In this paper we introduce a novel family of semantics called weakly complete semantics. Differently from Dung's complete semantics, weakly complete semantics employs a mechanism called undecidedness blocking by which the label undecided of an attacking argument is not always propagated to an otherwise accepted attacked argument. The new semantics...

Now at the forefront of automated reasoning, argumentation has become a key research topic within Artificial Intelligence. It involves the investigation of those activities for the production and exchange of arguments, where arguments are attempts to persuade someone of something by giving reasons for accepting a particular conclusion or claim as e...
Article
In Dung’s abstract semantics, the label undecided is always propagated from the attacker to the attacked argument, unless the latter is also attacked by an accepted argument. In this work we propose undecidedness blocking abstract argumentation semantics where the undecided label is confined to the strong connected component where it was generated...

The use of video games to support learning in the classroom became popular over the last two decades. Even though games have proved to be successful not only to improve the learning outcomes but also skills such as critical thinking and problem solving, it is still a challenge to adapt them to the classroom routine. Issues such as the lack of video...

In the last few decades several fields have made use of the construct of human mental workload (MWL) for system and task design as well as for assessing human performance. Despite this interest, MWL remains a nebulous concept with multiple definitions and measurement techniques. State-of-the-art models of MWL are usually ad-hoc, considering differe...

Conference Paper
In this paper we explore how the seminal Dung’s abstract argumentation framework can be extended to handle arguments containing gradual concepts. We allow arguments to have a degree of truth associated with them and we investigate the degree of truth to which each argument can be considered accepted, rejected and undecided by an abstract argumentat...

This study describes and evaluates a novel trust model for a range of collaborative applications. The model assumes that humans routinely chose to trust their peers by relying on few recurrent presumptions, which are domain independent and that form a recognisable trust expertise. We refer to these presumptions as trust schemes, the specialised ver...

Questions

Question (1)
Question
Micheal Staton said that "Stack Overflow is the new Computer Science department, where people go to learn together"
If we replace "Computer Science" with the more practical "Computer Programming", what is your opinion on this quote?
On one side, The Stack Overflow dataset has great potential for education, being the largest dataset of solved exercises, with a relatively good content and with a strong problem-based approach.
However, Stack Overflow, as it is, has clear limitations from an educational point of view: lack of structure, content too fragmented, potential problem of reliability of the content and there is little to support a learner (indeed, there is a lot more to support a professional). Stack Overflow has been criticized often for only encouraging "cut&paste" habits and quick answers.
My question is: Can we turn Stack Overflow ( and similar CoP) into a tool for teaching Computer Programming?
Maybe yes, maybe yes as a supplemental material for quizzes or exercises, or maybe no.
I am developing a research project to investigate the potential of such online communities in a teaching&learning context.
I'll be grateful if you can help me with your opinion.
If you want to go the extra mile, I have a 5-minute survey on the topic:

The crucial role of technology and serious games in teaching and learning scientific subjects, such as Mathematics, has been widely praised. However, there is a lack of information about how kids learn and what they think about digital learning games considering design, usability and fun. A recent survey of more than 300 academic papers revealed how the efficacy of serious games for scientific subjects is not yet proven and in this field science is far behind other subject areas like reading, writing and languages. The goal of this project is to understand how kids use digital web based games to learn and to develop a set of learning games and applications to teach mathematics concepts. The research has therefore a first explorative part, aiming to understand how digital games are perceived by stakeholders such as pupils, teachers, parents and education policy-makers; and a second experimental part where the efficacy of existing, modified and new developed games will be tested.
