Diagnóstico y tratamiento de los retrasos en lectoescritura: Descripción psicométrica de un grupo de niños desde la práctica clínica

Mientras los grandes principios sobre el origen de los retrasos en la adquisición de la lengua escrita siguen siendo hoy objeto de múltiples debates entre investigadores de diversas procedencias teóricas, la escuela continúa sin resolver el reto de la alfabetización de la población infantil en un porcentaje de casos relativamente elevado. Esos niños, que sin duda requieren una dedicación altamente individualizada por parte de especialistas, acuden por iniciativa de sus padres o a instancias de la propia escuela a consultas privadas o a servicios de apoyo psicopedagógicos de diversa índole, pero la dinámica de este tipo de consultas (sobrecarga de trabajo, falta de presupuesto, etc.) no permite habitualmente realizar una tarea de caracterización, control y seguimiento de la población tratada. Ese es precisamente el objetivo de este artículo, donde, en base a un respetable numero de expedientes clínicos, se ha realizado una caracterización diagnóstica y evolutiva de un grupo de niños con retraso lector, proponiendo vías de aproximación terapeutica.     

Building inclusion and resilience in students with and without SEN through the implementation of narrative speech,role play and creative writing in the mainstream classroom of primary education

ABSTRACT

Based on the theory of inclusion, the present 3-year pilot program (2013–2016) deals with narrative speech, role play and creative writing as a useful tool to build resilience in primary school students with and without Special Educational Needs (SEN) in the mainstream classroom. The specific aim of the program was to help students develop a series of fundamental psychosocial skills, such as a positive sense of inner self and the ability to cooperate and relate to others by familiarising with them in recognising and expressing the basic emotions of joy, sadness, fear and anger. Under the systematic cooperation among the general education teacher, the special education teacher and the rest of the teaching staff, the concept was to involve the maximum of the school teachers in order to create a Community of Practice, Collaboration, Sharing Learning and Action. Using an action-based research approach, the data from the present work allowed the participating students to demonstrate a range of socio-emotional skills, including those necessary for self-awareness. Similarly, the teachers involved in the project in each class built positive relations with their students and the rest of the teachers as well, whom they encouraged to participate in various collaborative tasks through similar programs.     

Critical thinking as the ability to sort and qualify the information available,to form one's own judgement

In an era marked by an excessive exposure to information and disinformation, this article explores how the public in France engages with critical thinking on the topics of scientific information and knowledge, as well as associated debates. First, a panel survey was carried out in 2022 by the science education centre Universcience in Paris in collaboration with the survey institute GECE. A total of 3,218 respondents participated in the survey in France. The survey questions focused on three themes: (1) the substantial relationship between respondents' scientific reasoning and critical thinking; (2) sources that respondents used for information, particularly on scientific subjects, to form an understanding of current events; (3) respondent relationships to discourses in the sciences and otherness in reasoning. In this study, critical thinking was defined as the ability to sort and make sense of available information and to question one's opinions. Also, the ability to discern trustworthy sources and information. In this approach, critical thinking is a condition for correctly assessing information on science topics. This is understood to include knowledge about science, its processes of knowledge production, and quality sources of information in the natural sciences. In this study, a Barometer of Critical Thinking was developed, and a survey was carried out. Survey results and the development of the barometer are described. Finally, we discuss how developing scientific literacy (knowledge about scientific facts, methods, practices and sources) is crucial in order to foster critical thinking on scientific information, knowledge, debates, and beyond.

Motion analysis of front crawl swimming applying CAST technique by means of automatic tracking

Abstract

Kinematic analysis of swimming is of interest to improve swimming performances. Although the video recordings of underwater swimmers are commonly used, the available methodologies are rarely precise enough to adequately estimate the three dimensional (3D) joint kinematics. This is mainly due to difficulties in obtaining the required kinematic parameters (anatomical landmarks, joint centres and reference frames) in the swimming environment. In this paper we propose a procedure to investigate the right upper limb’s 3D kinematics during front crawl swimming in terms of all elbow and shoulder degrees of freedom (three rotations of the shoulder, two of the elbow). The method is based upon the Calibrated Anatomical Systems Technique (CAST), a technique widely used in clinics, which allows estimation of anatomical landmarks of interest even when they are not directly visible. An automatic tracking technique was adopted. The intra-operator repeatability of the manual tracking was also assessed. The root mean squared difference of three anatomical landmarks, processed five times, is always lower than 8 mm. The mean of the root mean squared difference between trajectories obtained with the different methodologies was found to be lower than 20 mm. Results showed that complete 3D kinematics of at least twice as many frames than without CAST can be reconstructed faster and more precisely.     

An evaluation of an adaptive learning system based on multimodal affect recognition for learners with intellectual disabilities

Artificial intelligence tools for education (AIEd) have been used to automate the provision of learning support to mainstream learners. One of the most innovative approaches in this field is the use of data and machine learning for the detection of a student’s affective state, to move them out of negative states that inhibit learning, into positive states such as engagement. In spite of their obvious potential to provide the personalisation that would give extra support for learners with intellectual disabilities, little work on AIEd systems that utilise affect recognition currently addresses this group. Our system used multimodal sensor data and machine learning to first identify three affective states linked to learning (engagement, frustration, boredom) and second determine the presentation of learning content so that the learner is maintained in an optimal affective state and rate of learning is maximised. To evaluate this adaptive learning system, 67 participants aged between 6 and 18 years acting as their own control took part in a series of sessions using the system. Sessions alternated between using the system with both affect detection and learning achievement to drive the selection of learning content (intervention) and using learning achievement alone (control) to drive the selection of learning content. Lack of boredom was the state with the strongest link to achievement, with both frustration and engagement positively related to achievement. There was significantly more engagement and less boredom in intervention than control sessions, but no significant difference in achievement. These results suggest that engagement does increase when activities are tailored to the personal needs and emotional state of the learner and that the system was promoting affective states that in turn promote learning. However, longer exposure is necessary to determine the effect on learning.     

An Audio-Visual Approach to the Spanish Transition

Tele-revista was a biweekly Swiss television broadcast for Spanish immigrants living in Switzerland. It dealt with labour and migration-related issues in Switzerland, information about Spanish cultural manifestations, political rights and interviews with committed immigrants and key figures of Spanish politics in transit on Swiss soil. First aired in 1973, in the final years of General Franco's authoritarian regime, the TV magazine, initially broadcast on the three Swiss TV channels, is an unique source of the Spanish transition to democracy, seen through the eyes of Swiss TV-makers with the collaboration of some Spanish journalists. Tele-revista was aimed for a better integration of Spaniards within Swiss society, who were considered worse integrated than the Italians. The paper pursues to present a general portrayal of the broadcast with a special attention to the years of the Spanish transition to democracy by means of focussing on the information about social, cultural and political issues.     

Microfluidic-driven viral infection on cell cultures: Theoretical and experimental study

Advanced cell culture systems creating a controlled and predictable microenvironment together with computational modeling may be useful tools to optimize the efficiency of cell infections. In this paper, we will present a phenomenological study of a virus-host infection system, and the development of a multilayered microfluidic platform used to accurately tune the virus delivery from a diffusive-limited regime to a convective-dominated regime. Mathematical models predicted the convective-diffusive regimes developed within the system itself and determined the dominating mass transport phenomena. Adenoviral vectors carrying the enhanced green fluorescent protein (EGFP) transgene were used at different multiplicities of infection (MOI) to infect multiple cell types, both in standard static and in perfused conditions. Our results validate the mathematical models and demonstrate how the infection processes through perfusion via microfluidic platform led to an enhancement of adenoviral infection efficiency even at low MOIs. This was particularly evident at the longer time points, since the establishment of steady-state condition guaranteed a constant viral concentration close to cells, thus strengthening the efficiency of infection. Finally, we introduced the concept of effective MOI, a more appropriate variable for microfluidic infections that considers the number of adenoviruses in solution per cell at a certain time.
