Estudio de la dimensión subjetiva de la toma de decisiones en estudiantes de bachillerato mediante el cuestionario de estilo de decisión en el deporte (CETD)

[ES] Ruiz y Graupera (2005) desarrollaron y validaron el Cuestionario de Estilo de Decisión en el Deporte (CETD), que permite estudiar la dimensión subjetiva de la toma de decisiones de los jugadores. Los objetivos del presente estudio fueron: analizar el perfil decisional en deportes colectivos de estudiantes de Bachillerato mediante el CETD y comparar los resultados obtenidos en el cuestionario en función de la experiencia y el sexo. Ruiz and Graupera (2005) developed and validated the

A toolbox with DERIVE: calculus on several variables, Applications of Computer Algebra

A toolbox is a set of procedures taking advantage of the computing power and graphical capacities of a CAS. With these procedures the students can solve math problems, apply mathematics to engineering or simply reinforce the learning of certain mathematical concepts. From the point of view of their construction, we can consider two types of toolboxes: (i) the closed box, built by the teacher, in which the utility files are provided to the students together with the respective tutorials and several worksheets with proposed exercises and problems,

Algunas aportaciones sobre la enseñanza y divulgación de la ciencia

Se aportan una serie de ideas y consideraciones sobre temas variados relacionados tanto con el ámbito de la enseñanza como con el de la divulgación de las ciencias experimentales y, de forma específica, la química y la física. Las ideas expuestas en este artículo son, en buena medida, fruto del trabajo asociado a la preparación y celebración de una Jornada en Madrid, en 2012, sobre "Enseñanza y divulgación de la química y la física". Los trabajos presentados en dicho evento se recopilaron en un libro (escrito por 132 autores de distintos niveles educativos y países), con el mismo título y de libre acceso en Internet. Se aboga por favorecer: (i) una divulgación científica rigurosa, con objetivos claros y acordes al público al que va destinada, (ii) una enseñanza con metodologías variadas, e (iii) la imbricación de actividades divulgativas (museos, certámenes, páginas web...) y educativas. We discuss different topics related to science teaching and science outreach, focused especially on chemistry and physics. These ideas were most ly obtained from a 2012 symposium in Madrid about “Teaching and Outreach of Chemistry and Physics.” The papers presented in this symposium, written by 132 authors from different countries and working at di fferent educational levels, were published in a book with the same symposium title and with free access by internet. We emphasize: (i) rigorous science outreach with clear objectives that are well-focuse d on the intended audience; (ii) teaching based on a variety of methodologies, and; (iii) the interconnect ion of several outreach and educational activities (museums, contests, web pages).

Difference schemes for time-dependent heat conduction models with delay

Different non-Fourier models of heat conduction, that incorporate time lags in the heat flux and/or the temperature gradient, have been increasingly considered in the last years to model microscale heat transfer problems in engineering. Numerical schemes to obtain approximate solutions of constant coefficients lagging models of heat conduction have already been proposed. In this work, an explicit finite difference scheme for a model with coefficients variable in time is developed, and their properties of convergence and stability are studied. Numerical computations showing examples of applications of the scheme are presented.

A compact difference scheme for numerical solutions of second order dual-phase-lagging models of microscale heat transfer

Dual-phase-lagging (DPL) models constitute a family of non-Fourier models of heat conduction that allow for the presence of time lags in the heat flux and the temperature gradient. These lags may need to be considered when modeling microscale heat transfer, and thus DPL models have found application in the last years in a wide range of theoretical and technical heat transfer problems. Consequently, analytical solutions and methods for computing numerical approximations have been proposed for particular DPL models in different settings. In this work, a compact difference scheme for second order DPL models is developed, providing higher order precision than a previously proposed method. The scheme is shown to be unconditionally stable and convergent, and its accuracy is illustrated with numerical examples.

Communication in the Seventh Grade Classroom

Reflections on communication in the learning process at the level of the seventh year of secondary education based on the methodological and pedagogical approaches, considered in research of a multidisciplinary team of the CIDE of UNA (National University), with the aim of building the “teaching performance profile for the seventh year of Costa Rican education”. It demonstrates the role of teachers to ensure favorable communication links to the learning process, not only to capture the attention and interest of students through varied and systematic motivations, but also by the honesty, openness, personal example and involvement in the task, problems and aspirations of students.
