About assessing the learning of students with dyscalculia
García Planas, María Isabel; García-Camba Vives, María Victoria
Dyscalculia is a neurodevelopmental disorder that affects to the capacity for calculation, interfering with the academic performance, the level of social inclusion, the access to the working world, and especially in the realization, both personal and professional of the people who suffer it. This learning disability is nearly as common as dyslexia, nevertheless, it is studied much less, and it is worse understood, and so many times it is diagnosed inconsistently. With regard to academic performance, efforts are being made to improve learning, both at the level of the emerging scientific field of educational neuroscience and from the point of view of education. However, to date, scientists have only been studying how to help children affected by dyscalculia to develop new brain strategies that aim to improve their learning without taking into account the way to evaluate these learning. Through the exploration of subjacent neurocognitive processes inherent to practice and educational theory, the main objective of this work is to analyse the possible difference in the brain function of affected individuals with dyscalculia in the performance of evaluation tests in order to find the best way to be evaluated, to intervene in the strengthening of arithmetic processing and to improve their performance and self-esteem. The methodology used to achieve the desired goal is to analyse the activity of the brain during computation and answering test questions by using evoked potentials and to check with the dyscalculic students as they reasoned during the performing tests comparing them with students who do not have this learning difficulty. After the analysis carried out, we concluded that to evaluate students with dyscalculia, the test type should be avoided and must use alternative evaluation methods such as the oral examination, while at the same time allowing certain actions that can help them. Due to the difficulty of learning about the people who suffer this difficulty, the probability of them responding poorly in this kind of evaluation, regardless of the knowledge of the subject it is very high, so the result of the test is not valid to assess your learning, which is the final objective of the test

The emerging scientific field of educational neuroscience is playing a significant role in the exploration of the subjacent neurocognitive processes underlying the practice and educational theory. Nevertheless, it can do not lose sight of the fact that the relationship between education and neuroscience research is complicated because education is not only based on neuronal relations but also have external factors such as the family environment and social interactions of teachers and students in a classroom. In a study about the analysis of the neuropsychological process of dyscalculia, it was highlighted that this is done through a circuit of specialised neurons. Considering that a fundamental characteristic of these neural networks is that they work automatically, receiving information in a certain «format» transforming it into a different one thanks to the «neuronal plasticity». So it seems, by means of training the neuroplasticity, it can be possible to rebuild deteriorated brain functions and help children who are affected on dyscalculia to develop new brain strategies which are aimed to improve the difficulties associated with dyscalculia efficiently. The main goal of this work is to analyse the possible difference in brain function on affected dyscalculia individuals in order to intervene in the strengthening of arithmetic processing leading to an efficient education based on evidence for students affected by dyscalculia.

Multi-agent linear systems with noise. Solving decoupling problem
García Planas, María Isabel
Dynamical multi-agent systems are being extensively studied by researchers in the field of control theory. It is due to the multi-agents appear in different study subjects as for example in the consensus problem of communication networks, formation control of mobile robots or cooperative control of unmanned aerial vehicles.
The disturbance decoupling problem for linear dynamical systems with noise was the starting point for the development of a geometric approach to systems theory. The problem consists in that the disturbance not interfere with the solution of the linear dynamical system; in other words, to find a compensator such that the closed loop transfer matrix from disturbance to output is 0.
Several multiagents linear systems are affected by noises, nevertheless almost all the existing results in consensus problem, do not take into account the effects of these noises. The goal of this paper is to advance in the study of the consensus problems under noise disturbances using linear algebra techniques.

In the last years, the dynamic control of switched systems have attracted considerable interest, because these systems arise in many engineering fields. Controllability and observability of such systems, which are fundamental qualitative properties, have been studied by various researchers. In this work we focus on structural controllability/observability, using geometrical techniques as miniversal deformations.
