    Improving university argumentative writing through online training

    Full text link
    Writing an argumentation about a controversial issue from contradictory sources is a challenging task. It involves understanding, managing, and generating arguments and counterarguments from different sources to support a final position, conveyed in a formal structure. Despite its difficulty, argumentative writing is not often taught in higher education in Spain. Furthermore, online interventions regarding this type of task are scarce. For this reason, we designed and evaluated virtual training aimed at writing integrative and wellstructured arguments in a distance learning university. Sixty-eight undergraduates participated in this pre-post with a control group design. The training included explicit instruction through video lectures and practice exercises with immediate feedback using open online resources (e.g., Moodle). The results show that after the instruction the participants' written products improved both in their structure, the number of arguments for the against-position, and the degree of integration of the two perspectives. However, those products that presented medium or maximum integration were still limited. These results illustrate how online instruction of argumentative writing can be implemented in higher education with positive results. However, students still need more support to expand their skills for generating integrative synthesis. Considering these results, we propose further improvements in the designed training. : Earli | This article is published under Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 Unported license

    Análisis observacional de la conducta de los entrenadores de voleibol de diferentes niveles de formación y años de experiencia = Observational analysis of the behaviour of volleyball coaches in different levels of training and years of experience

    El comportamiento de los entrenadores en competición es uno de los aspectos más importantes desde el punto de vista de la dirección de equipo (Díaz, 1992), destacando su capacidad de comunicación, la cual marca la diferencia entre un entrenador exitoso o no. Se han observado las conductas de 36 entrenadores de Voleibol de diferentes niveles de formación y experiencias, durante la dirección de 130 sets en la temporada 2015/2016. Para ello se ha utilizado el método de observación deportiva Coaching Behavior Assesment System (CBAS) de Smith, Smoll y Hunt (1977) y un sistema propio adaptado a las categorías más importantes en la dirección de equipo. Los datos fueron recogidos por observación directa. El fin de este estudio es comparar los resultados de las conductas observadas de los entrenadores en función de su titulación y años de experiencia. Se procedió a un análisis de las conductas observadas y las conclusiones indicaron que los entrenadores con menos nivel y experiencia interaccionan menos con sus jugadores y con mayores acciones positivas que los de mayor nivel y experiencia ya que sus interacciones son más abundantes y con mayor exigenci

    Non-homogeneous Fabry-Pérot Antenna Design at Ku-band

    Get PDF
    A novel technique to design Fabry-Pérot antennas with non-homogeneous PRS is described. It takes advantage of a transmission line circuit model to efficiently obtain all necessary unit cell designs that satisfy the cavity resonance condition. This approach allows an increase in directivity for a given footprint without decreasing the bandwidth. Some design examples are presented, showing the evolution from a simple single-layer PRS to a non-homogeneous two-layers one. Through electromagnetic simulations, the latter one achieves an increase of about 3 dB in directivity while maintaining the bandwidth. This way, the gain-bandwidth product is improved from a value of 5 to almost 9, effectively raising the antenna efficiency.This work has been supported by the Spanish Ministerio de Ciencia, Innovación y Universidades (MCIU) (Contrato Juan de la Cierva-Incorporación) under Grant IJC2018-038440-I and by the MCIU/AEI/FEDER (Programa Estatal de I+D+i Orientada a los Retos de la Sociedad) under grant RTI2018-097098-J-I00.

    Non-homogeneous Fabry-Pérot antenna design process to improve aperture efficiency

    A novel technique to design Fabry-Pérot antennas with non-homogeneous partially reflective surfaces (PRSs) is described. It uses a transmission line circuit model to efficiently obtain all necessary unit cell designs that satisfy the cavity resonance condition. This method allows an increase in directivity without reducing the bandwidth for a given footprint. Some design examples in the Ku-band are presented, showing the evolution from a simple single-layer PRS to a non-homogeneous two-layer one. The latter achieves an increase of about 3 dB in directivity while maintaining the bandwidth in electromagnetic simulations. This way, the gain-bandwidth product is improved from a value of 5 to almost 9, effectively raising the antenna efficiency.This work was supported by the Spanish Ministerio de Universidades (Programa para la Formación del Profesorado Universitario) under grant FPU20/03240, by MCIU/AEI/FEDER (Programa Estatal de I+D+i Orientada a los Retos de la Sociedad) under grant RTI2018-097098-J-I00, and by the regional government (Junta de Andalucía) PAIDI 2020 under grant PY20 00452.
