Analizando los resultados académicos en la Educación Superior en España

The development of the European Higher Education Area has been a process of modernization in many universities. Teaching methodologies have undergone a process of continuous change to meet the demands for high quality leading to a need for enhancement in the learning assessment methodologies as well. The objective of this study is to analyse student´s academic performance measured through coursework vs. final exam and to ascertain the factors that could explain the difference. Regression and variance analysis are carried out over the grades and responses to a questionnaire on a sample of 298 students of different subjects in a Spanish university. The results show that there are differences between continuous assessment and the final examination marks.Ministerio de Economía y Competitividad FFI2013-41235-

Active seminars: A pedagogical resource to motivate students

La Facultad de Ciencias Económicas y Empresariales de la Universidad Complutense de Madrid, para llevar a cabo la adaptación al Espacio Europeo de Educación Superior, además de rediseñar los planes de estudio ha reestructurado la docencia añadiendo una hora adicional para los seminarios. En la asignatura de contabilidad se han planteado y realizado los denominados “seminarios activos”. El objetivo de los mismos es doble: por un lado, que el profesor pueda aplicar una metodología de enseñanza activa y, por otro, integrar los contenidos teóricos del programa a la práctica de la realidad empresarial. Además la enseñanza impartida en los seminarios se ha apoyado en un entorno virtual de aprendizaje. El objetivo de este trabajo es presentar un nuevo recurso para la docencia: los “seminarios activos” a través de la experiencia docente de tres profesores de la asignatura de Contabilidad Financiera de primer curso en los Grados de Economía y de ADE para los seminarios. Posteriormente, se ha realizado una encuesta a los alumnos para la medir su percepción y motivación en estos seminarios. Los resultados obtenidos de los seminarios activos se pueden resumir en un aprendizaje más profundo de la asignatura y una mayor motivación hacia los contenidos teóricos. No obstante, el alumno ha percibido una carga de trabajo mayor en esta asignatura que en el restoThe Faculty of Economics and Business Administration from the Complutense University of Madrid in order to adapt to the European Higher Education Area (EHEA) has redesigned the study plan and teaching has been restructured adding an extra hour for seminars. For the accounting subject, active seminars have been proposed. The aim of these seminars is twofold: first, for the teacher to implement an active teaching methodology and, second, to integrate the theoretical content of the subject to the real world business. Additionally teaching has been supported in a virtual learning environment. This paper presents the experience of three teachers teaching the subject of Financial Accounting in the first-year of the Economics and Business Administration Degrees for the seminars. A survey has been designed to measure the students’ perception and motivation towards these seminars. The results of the active seminars can be summarized in a deeper understanding of the subject and greater motivation to the theoretical concepts. However, the student has received an increased workload in this subject comparing to the others

Are the new EHEA assessment methods appropriate to evaluate the academic performance of students? An experience in Financial Accounting

La Facultad de Ciencias Económicas y Empresariales de la Universidad Complutense de Madrid ha puesto en marcha durante el curso 2009-2010 la implantación de los nuevos Grados en Administración y Dirección de Empresas y en Economía, ajustándose a los nuevos criterios recogidos en el marco del Espacio Europeo de Educación Superior (EEES). Una de las novedades es la evaluación acumulativa por actividades frente a la evaluación tradicional. Profesores de Contabilidad Financiera de primer curso han aplicado la metodología de enseñanza activa y su consecuente método de evaluación. Los resultados obtenidos en este trabajo empírico cuestionan este método de evaluación y promueve mejoras alternativas para implementar otros tipos de evaluación, además de que podría ser extrapolable a otras materias. Todo ello promueve una mejora continua en la docencia universitaria y un aprendizaje significativo del alumno.The Economics and Business Administration School of the Complutense University of Madrid has launched during the 2009-2010 academic year the new degrees in Economics and in Business Administration. These degrees have adjusted to the new criteria established in the European High Education Area (EHEA) framework. A new characteristic is the student cumulative activities assessment opposite to the traditional way of assessment. Three Financial Accounting lecturers have designed and applied, in the first year degree, active teaching methodologies and its consequent evaluation. The results of this empirical experiment show it is not the optimal assessment method and suggests other alternative methodologies could suit best. All of this together motivates a continuous improvement in the university teaching process and a deep learning for the students

Single hadron response measurement and calorimeter jet energy scale uncertainty with the ATLAS detector at the LHC

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of sqrt(s) = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of K_s and Lambda particles, the calorimeter response to specific types of particles (positively and negatively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral particles to jets. The response uncertainty is 2-5% for central isolated hadrons and 1-3% for the final calorimeter jet energy scale.Comment: 24 pages plus author list (36 pages total), 23 figures, 1 table, submitted to European Physical Journal

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Measurement of χ c1 and χ c2 production with s√ = 7 TeV pp collisions at ATLAS

The prompt and non-prompt production cross-sections for the χ c1 and χ c2 charmonium states are measured in pp collisions at s√ = 7 TeV with the ATLAS detector at the LHC using 4.5 fb−1 of integrated luminosity. The χ c states are reconstructed through the radiative decay χ c → J/ψγ (with J/ψ → μ + μ −) where photons are reconstructed from γ → e + e − conversions. The production rate of the χ c2 state relative to the χ c1 state is measured for prompt and non-prompt χ c as a function of J/ψ transverse momentum. The prompt χ c cross-sections are combined with existing measurements of prompt J/ψ production to derive the fraction of prompt J/ψ produced in feed-down from χ c decays. The fractions of χ c1 and χ c2 produced in b-hadron decays are also measured

Measurement of the flavour composition of dijet events in pp collisions at root s=7 TeV with the ATLAS detector

This paper describes a measurement of the flavour composition of dijet events produced in pp collisions at √s=7 TeV using the ATLAS detector. The measurement uses the full 2010 data sample, corresponding to an integrated luminosity of 39 pb−1. Six possible combinations of light, charm and bottom jets are identified in the dijet events, where the jet flavour is defined by the presence of bottom, charm or solely light flavour hadrons in the jet. Kinematic variables, based on the properties of displaced decay vertices and optimised for jet flavour identification, are used in a multidimensional template fit to measure the fractions of these dijet flavour states as functions of the leading jet transverse momentum in the range 40 GeV to 500 GeV and jet rapidity |y|<2.1. The fit results agree with the predictions of leading- and next-to-leading-order calculations, with the exception of the dijet fraction composed of bottom and light flavour jets, which is underestimated by all models at large transverse jet momenta. The ability to identify jets containing two b-hadrons, originating from e.g. gluon splitting, is demonstrated. The difference between bottom jet production rates in leading and subleading jets is consistent with the next-to-leading-order predictions

Measurement of the production of a W boson in association with a charm quark in pp collisions at √s = 7 TeV with the ATLAS detector

The production of a W boson in association with a single charm quark is studied using 4.6 fb−1 of pp collision data at s√ = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. In events in which a W boson decays to an electron or muon, the charm quark is tagged either by its semileptonic decay to a muon or by the presence of a charmed meson. The integrated and differential cross sections as a function of the pseudorapidity of the lepton from the W-boson decay are measured. Results are compared to the predictions of next-to-leading-order QCD calculations obtained from various parton distribution function parameterisations. The ratio of the strange-to-down sea-quark distributions is determined to be 0.96+0.26−0.30 at Q 2 = 1.9 GeV2, which supports the hypothesis of an SU(3)-symmetric composition of the light-quark sea. Additionally, the cross-section ratio σ(W + +c¯¯)/σ(W − + c) is compared to the predictions obtained using parton distribution function parameterisations with different assumptions about the s−s¯¯¯ quark asymmetry

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 8 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three leptons and missing transverse momentum is presented. The analysis is based on 20.3 fb−1 of s√ = 8 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with the Standard Model expectations and limits are set in R-parity-conserving phenomenological Minimal Supersymmetric Standard Models and in simplified supersymmetric models, significantly extending previous results. For simplified supersymmetric models of direct chargino (χ˜±1) and next-to-lightest neutralino (χ˜02) production with decays to lightest neutralino (χ˜01) via either all three generations of sleptons, staus only, gauge bosons, or Higgs bosons, (χ˜±1) and (χ˜02) masses are excluded up to 700 GeV, 380 GeV, 345 GeV, or 148 GeV respectively, for a massless (χ˜01
