An eMath Teacher TOOL for ACTIVE LEARNING FLEURY'S ALGORITHM

An eMathTeacher [Sánchez-Torrubia 2007a] is an eLearning on line self assessment tool that help students to active learning math algorithms by themselves, correcting their mistakes and providing them with clues to find the right solution. The tool presented in this paper is an example of this new concept on Computer Aided Instruction (CAI) resources and has been implemented as a Java applet and designed as an auxiliary instrument for both classroom teaching and individual practicing of Fleury’s algorithm. This tool, included within a set of eMathTeacher tools, has been designed as educational complement of Graph Algorithm active learning for first course students. Its characteristics of visualization, simplicity and interactivity, make this tutorial a great value pedagogical instrument

Parenting style: influence on gifted children psychological adjustment

Este trabajo se centra en las influencias positivas y negativas de la práctica educativa que los padres ejercen sobre el desarrollo de los niños con altas capacidades. El resultado de este estudio teórico muestra que las familias cuyas características esenciales están basadas en una dinámica de funcionamiento en la que priman la armonía y la coherencia se asocian tanto al desarrollo óptimo intelectual y de la autoestima como al adecuado funcionamiento emocional e intelectual. En contraste, las familias en las que la falta de coherencia y la existencia de una dinámica de funcionamiento caracterizada por bajos niveles de comunicación, afecto y control del comportamiento se asocian a la aparición de comportamientos de riesgo. De acuerdo con la literatura existente, las prácticas educativas más efectivas para el ajuste y bienestar de niños y adolescentes son las autoritativas. En el caso de los niños con altas capacidades, la mayoría de los padres se muestran acordes con estas prácticas de crianza aunque en algunos casos se han encontrado diferencias en las pautas de actuación de madres y padres. Los determinantes parentales que potencian el ajuste positivo de los hijos con altas capacidades son: nivel intelectual, nivel educativo y rendimiento académico alto, y en ausencia de estas características, interés de los padres hacia la educación y el aprendizaje.This paper focused on influence of parenting practice on gifted children´s development. The result of this study showed that harmony and coherent families are associated both to self-stem, effective intellectual development and social and emotional functioning. In contrast, family discord relates to risk behaviour. According to literature, the most effective parenting practice for children development is authoritative, In gifted children case, most of the parents showed educative patterns framed in the authoritative parenting style although in some cases it was found differences between mother and father. Parents determinants making possible positive adjustement in their gifted children are: high intellectual level, high school achievement and high level of school performance. In absence of this, parent´s high interest on education and learning act as a substitute of these last cognitive and educational characteristics.peerReviewe

La topología en la formación de profesores

En la Facultad de Ingeniería de la Universidad Autónoma de Querétaro, en México, existe y funciona desde hace varios años la Maestría en Docencia de las Matemáticas. Este posgrado está dirigido primordialmente a maestros de Matemáticas en ejercicio, principalmente de los niveles medio y medio superior, cuya característica común es que no son matemáticos de profesión, es decir, no son egresados de una licenciatura en matemáticas. En este contexto, en dicha maestría se ofrece la materia de Topología como curso optativo de los últimos semestres. Como encargados de impartirla, hemos observado que los libros existentes de este tema están diseñados fundamentalmente para los estudiantes de las licenciaturas de matemáticas, con un rigor bien establecido, o bien son trabajos a nivel de divulgación que presentan solo ciertos aspectos geométricos del tema. De cualquier modo, estos dos extremos no nos parecen apropiados para los fines que se persiguen en esta maestría y en general en la formación de profesores

Vocabulary acquisition through playful activities in the English classroom

Treball final de Màster Universitari en Professor/a d'Educació Secundària Obligatòria i Batxillerat, Formació Professional i Ensenyaments d'Idiomes. Codi: SAP419. Curs acadèmic 2014-2015This didactic unit is intended to improve and expand vocabulary acquisition for first grade students of secondary level, through the use of playful activities in the classroom. An interesting point in order to motivate and engage students is the use of games in the English classroom. In this way, they feel comfortable and have a good opportunity to speak in the foreign language without paying much attention to their pronunciation or grammar mistakes as it occurs in a spontaneous way. Vocabulary acquisition is the basis for learning any language so that, throughout this paper, there will be considered aspects that ensure the assimilation of the contents raised when implementing theoretical framework such as guidelines to develop a playful activity or the cognitive development of learners in the first grade of the secondary level

A Concurrency-Agnostic Protocol for Multi-Paradigm Concurrent Debugging Tools

Today's complex software systems combine high-level concurrency models. Each model is used to solve a specific set of problems. Unfortunately, debuggers support only the low-level notions of threads and shared memory, forcing developers to reason about these notions instead of the high-level concurrency models they chose. This paper proposes a concurrency-agnostic debugger protocol that decouples the debugger from the concurrency models employed by the target application. As a result, the underlying language runtime can define custom breakpoints, stepping operations, and execution events for each concurrency model it supports, and a debugger can expose them without having to be specifically adapted. We evaluated the generality of the protocol by applying it to SOMns, a Newspeak implementation, which supports a diversity of concurrency models including communicating sequential processes, communicating event loops, threads and locks, fork/join parallelism, and software transactional memory. We implemented 21 breakpoints and 20 stepping operations for these concurrency models. For none of these, the debugger needed to be changed. Furthermore, we visualize all concurrent interactions independently of a specific concurrency model. To show that tooling for a specific concurrency model is possible, we visualize actor turns and message sends separately.Comment: International Symposium on Dynamic Language

Species Delimitation, Phylogenetics, and Biogeography of the Catfish Genus \u3ci\u3eRhamdia\u3c/i\u3e Bleeker (Heptapteridae) of Central America and the Trans-Andean Region of Colombia

A recent taxonomic revision of the Neotropical catfish genus Rhamdia (Pisces: Siluriformes: Heptapteridae) reduced a number of described species to synonymy, especially under a broadly circumscribed R. quelen. Evidence is presented here from DNA sequence data, external and internal morphology, and morphometrics that argues for the recognition of R. guatemalensis in Central and northern South America and R. saijaensis and R. cinerascens in the Pacific drainages of Colombia and Ecuador, respectively. The DNA data indicate that all trans-Andean samples form a monophyletic group, within which there are separate clades corresponding to R. laticauda and the synonymized R. guatemalensis, R. saijaensis, and R. cinerascens. The morphometric data substantiate the phylogenetic groupings, and in external morphology, each putative species has diagnostic characters. The external and internal morphological differences and phylogenetic relationships indicate that these groups are both recognizable and represent independent lineages, which argue for their recognition as species

Hydrogenation of furfural over supported Pd catalysts

Lignocellulosic biomass is the most abundant and economical non-fossil carbon source. Furthermore, it is not competitive with the food chain, coming from lignocellulosic wastes including agricultural and food processing, local urban solid and forestry wastes. However, these are made up of complex carbohydrates (mainly, cellulose and hemicellulose), which require to be broken down in their respective monomers. The hemicellulose is mainly composed of pentosans, which, after an initial hydrolysis step, are dehydrated to furfural. Furfural is an important platform molecule, since it has a wide range of applications, being considered the main chemical, aside from bioethanol, obtained from the sugar platform for the synthesis of chemicals, for plastics, agrochemical and pharmaceutical industries. In the present work, the hydrogenation of furfural in gas phase has been studied by using Pd as active phase, and different metal oxides as support, in order to elucidate the influence of the support on the catalytic performance. Furfural can be converted into chemicals with important applications in many different industrial fields. Thus, reduction of furfural can proceed through different pathways depending on the experimental conditions, where the nature of the catalysts plays a key role. In the case of Pd-based catalysts, the main products come from the decarbonylation of furfural.The catalytic results reveals that the nature of the support exerts an important influence on furfural conversion and yield. The highest conversion (92% after 5 h of TOS at 463 K) was attained with a Pd-SiO2 catalyst, with a furan yield of 70 mol%. This catalyst is the most selective to furan and a moderate deactivation is only observed after 5 h reaction. The catalytic performance demonstrates that decarbonylation reaction was the main pathway, although the formation of furfuryl alcohol and 2-methylfuran also suggests that the hydrogenation of the carbonyl group of furfural takes place.Universidad de Málaga.
