Perception of teacher trainees about the potential of information technology in education: from expectation to reality

Se presenta una investigación sobre el uso de las nuevas tecnologías por parte de estudiantes de magisterio (N = 158) del CES Cardenal Spínola CEU (centro adscrito a la Universidad de Sevilla) con una media de edad de 22 años y la percepción que tienen, como futuros docentes, sobre su potencial didáctico. Se ha utilizado como instrumento para la recogida de datos, un cuestionario que incluye algunos ítems en los que hay que indicar el posible uso de ciertos recursos y otros, tipo Likert, en los que se debe mostrar el grado de acuerdo con algunas afirmaciones. Los resultados indican que los estudiantes mantienen una actitud general favorable hacia las TIC, resultando usuarios habituales y confiados y mostrando una visión positiva, un tanto idealizada y, en cierto modo, alejada de lo que podría constituir un modelo crítico, y muy en la línea de ciertas corrientes de pensamiento en el campo de la tecnología educativa en los 80 y 90. Esta visión, sin embargo, no se plasma en sus actividades de programación didáctica, evidenciando una disonancia entre uso personal de las TIC y creencia sobre su valor en educación, por un lado, y su práctica pedagógica en formación por otro. El trabajo concluye con una propuesta de orientaciones sobre las actuales asignaturas de los planes de estudios de Grado.We present research on the use of new technologies by teacher trainees (N = 158) whose average age is 22 and who are studying at “Cardenal Spínola” Teacher Training College (attached to the University of Seville). We investigate their perception, as future teachers, about the didactic potential of ICT. As an instrument to collect data, we have used a questionnaire which includes some items in which they have to indicate the possible use of certain resources and others, of the Likert type, in which they must show their degree of agreement with some affirmations. The results indicate that students maintain a general favorable attitude towards Information Technology, they are regular users, confident and show a positive view, a little idealized, and somewhat distant from what could be established as a critical model, and very much the same as certain lines of thinking in the field of educational technology in the 80s and 90s. This view, however, is not reflected in their activities on didactic programing, demonstrating disagreement between personal use of information technology and beliefs about its value in education, on the one hand, and its pedagogical practice in training on the other. The paper ends with a proposal of guidelines for the present subjects on the degree course

Reaction time on fencing and karate high level athletes

The great speed of the actions in combat sports makes very difficult to react quickJy without mistakes. If the fighter had longer time to react, their reaction would be more accurate. This fact gives relevance to choice lime reaction (CRT) studies on these kinds of sports. The importance of the athletes1 physical or psychological abilities varies depending on the sporl played. According to the requirements of the speciality, players who reach Ihe maximum level will be those who have the characteristics requested to compete on it. These abilities could be innate or "life-long" acquired by training. Previous studies have not confirmed yet in which sports reaction time is more important, in addition, previous measurements should be considered with caution because some of Ihem included movement time in the reaction time results (Martmez de Quel, 2003). An approach to gel further knowledge about this subject, it is comparing the results of e\perts in two or more disciplines with unspecific tests, in which previous sport experience is not required in order to perform the lest

El alumnado con TDAH (hiperactividad) como colectivo en riesgo de exclusión social: propuestas de acción y de mejora

La hiperactividad es algo más que un trastorno simple, negativo y defectuoso. Las personas con TDAH tienen un potencial latente del que nadie habla (como la creatividad, el ingenio, la hiperconcentración, la sensibilidad, entre otros). Ser hiperactivo es positivo si tenemos la habilidad de comprender y tratar el trastorno desde una perspectiva educativa diferente ya que el alumnado con TDAH es uno de los colectivos que suman más amonestaciones, sanciones y expulsiones en los centros educativos de nuestro país. Sin embargo, estos niños pueden tener éxito académico y, posteriormente, en su vida laboral y afectiva, si previamente hemos sabido comprenderlos y actuar con un proceso educativo adecuado a su idiosincrasia y si hemos sabido otorgar cierto grado de organización y reencauzamiento en sus mentes a veces infravaloradas. Para ello, las administraciones públicas educativas deben desarrollar estrategias de formación eficientes para formar a un profesorado que, muchas veces, asiste desorientado e impotente a un comportamiento caótico, desordenado e impulsivo que puede provocar serios conflictos no sólo en la enseñanza sino en el mismo clima de convivencia escolar.Hyperactivity is more than a simple, negative and defective disorder. People with ADAH have a latent potential which nobody talks about (like the creativity, wit, hyperconcentration, sensitivity, etc.) To be a hyperactive is positive if we have the ability of understanding and treating the disorder from a different educational perspective, because the students with ADAH is one of the collectives which adds more punishments, sanctions and expulsions in the educational centres of our country. However, these children can succeed academically and later in their job and affective life, if we have previously been able to understand them and act with an appropriate educational process to their idiosyncratic aspects and if we have given certain organizational level and guidance in their minds sometimes underestimated. For these reasons, the public educational administrations must develop sufficient formative strategies to train a teaching staff that sometimes is disoriented and impotent towards a chaotic, disordered and impulsive behaviour which can provoke serious conflicts not only in the teaching but in the same climate of school living.Fil: Guerrero López, José Francisco.

The newcomer takes it all: the invader Texas citrus mite, Eutetranychus banksi (Acari: Tetranychidae), displaces the resident relatives in citrus agrosystems

[EN] Many studies have emphasized the importance of interspecific competition in shaping natural ecosystem communities. In contrast, few investigations have explored the role of competition in agricultural environments after the arrival of an invasive pest species. We evaluated the ecological impact produced by the invasive Texas citrus mite, Eutetranychus banksi (McGregor), on the resident spider mites Panonychus citri (McGregor) and Eutetranychus orientalis (Klein) on the main citrus crop area in Eastern Spain. Since its arrival in 2013, E. banksi has become the most common and abundant spider mite on citrus, apparently leading to a reduction in the presence and geographic range of the other related species. Competitive relationships were detected between E. banksi-E. orientalis and E. banksi-P. citri pairs using co-occurrence analysis. Furthermore, generalized linear model analysis showed that the probability of finding E. orientalis or P. citri decreases with increasing E. banksi density and vice versa. Principal component analysis and permutational multivariate analysis of variance found competition between these two pairs, and also between the E. orientalis-P. citri pair. Redundancy and variation partitioning analysis revealed how the geographic distribution of the three spider mites is not caused by the environmental conditions, but it is strongly influenced by their colonization history and competitive relationships, since the areas with the highest density of the three species are related to their place of first detection, and do not coincide geographically. Finally, the mechanisms that may be involved in the competitive displacement and the possible future scenarios are discussed.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

A Role for DPPX Modulating External TEA Sensitivity of Kv4 Channels

Shal-type (Kv4) channels are expressed in a large variety of tissues, where they contribute to transient voltage-dependent K+ currents. Kv4 are the molecular correlate of the A-type current of neurons (ISA), the fast component of ITO current in the heart, and also of the oxygen-sensitive K+ current (KO2) in rabbit carotid body (CB) chemoreceptor cells. The enormous degree of variability in the physiological properties of Kv4-mediated currents can be attributable to the complexity of their regulation together with the large number of ancillary subunits and scaffolding proteins that associate with Kv4 proteins to modify their trafficking and their kinetic properties. Among those, KChIPs and DPPX proteins have been demonstrated to be integral components of ISA and ITO currents, as their coexpression with Kv4 subunits recapitulates the kinetics of native currents. Here, we explore the presence and functional contribution of DPPX to KO2 currents in rabbit CB chemoreceptor cells by using DPPX functional knockdown with siRNA. Additionally, we investigate if the presence of DPPX endows Kv4 channels with new pharmacological properties, as we have observed anomalous tetraethylammonium (TEA) sensitivity in the native KO2 currents. DPPX association with Kv4 channels induced an increased TEA sensitivity both in heterologous expression systems and in CB chemoreceptor cells. Moreover, TEA application to Kv4-DPPX heteromultimers leads to marked kinetic effects that could be explained by an augmented closed-state inactivation. Our data suggest that DPPX proteins are integral components of KO2 currents, and that their association with Kv4 subunits modulate the pharmacological profile of the heteromultimers
