Assessment of problem solving in computing studies

The assessment of learning outcomes is a key concept in the European Credit Transfer and Accumulation System (ECTS) since credits are awarded when the assessment shows the competences which were aimed at have been developed at an appropriate level. This paper describes a study which was first part of the Bologna Experts Team-Spain project and then developed as an independent study. It was carried out with the overall goal to gain experience in the assessment of learning outcomes. More specifically it aimed at 1) designing procedures for the assessment of learning outcomes related to these compulsory generic competences; 2) testing some basic psychometric features that an assessment device with some consequences for the subjects being evaluated needs to prove; 3) testing different procedures of standard setting, and 4) using assessment results as orienting feedback to students and their tutors. The process of development of tests to carry out the assessment of learning outcomes is described as well as some basic features regarding their reliability and validity. First conclusions on the comparison of the results achieved at two academic levels are also presented.

Caracterización de ambientes sonoros en recintos universitarios: influencia del ruido sobre procesos cognitivos básicos

El interés por el estudio de la problemática del ruido en las escuelas y sus efectos sobre los estudiantes a nivel universitarios, es un tema que no ha sido estudiado debidamente. Desgraciadamente, en el ámbito educativo universitario, no existen regulaciones específicas que permitan determinar parámetros preventivos, ni procedimientos de evaluación de ruido dentro de este tipo de instalaciones educativas. Debido a la importancia de los efectos que el ruido tiene sobre la salud y la calidad de vida de los estudiantes universitarios, y consecuentemente en el rendimiento académico; es de suma importancia desarrollar mecanismos que estudien y planteen soluciones que ayuden a garantizar la mejora de la calidad de vida de la población estudiantil. En este trabajo se ha presentado un extenso trabajo que incluye el estudio de los ambientes sonoros a los que los estudiantes universitarios se ven expuestos día a día y se proponen acciones que ayudan a mejorar la calidad acústica en instalaciones educativas. Así mismo se evidencian los efectos que tiene este contaminante sobre la salud psicológica y por consecuencia en el desarrollo intelectual de los estudiantes. Por un lado, se incluye una propuesta de metodología que ayuda a la correcta caracterización de los ambientes sonoros en los cuales se desarrollan los estudiantes a nivel universitario. Esta se realizó haciendo un completo registro de los niveles sonoros durante sus actividades diarias. Así mismo, una encuesta fue aplicada a estudiantes para conocer la percepción que se tiene sobre las condiciones sonoras en ambientes universitarios. Así mismo, se realizó un estudio de la calidad sonora en instalaciones universitarias, el cual deriva la valoración de la molestia al ruido. Se propone una escala de valoración de molestia al ruido, la cual deriva el diseño de una propuesta con acciones de bajo coste frente al ruido. Por otro lado, se evidencian los trastornos que ocasiona este contaminante sobre la salud psicológica de los estudiantes y que afectan el desarrollo académico de estos. Se realizó primeramente la valoración de la atención y la memoria por medio de test psicométricos estandarizados y otros diseñados para este estudio en particular. Por último, con la finalidad de obtener datos objetivos y confiables que permitieron relacionar la influencia negativa del ruido de fondo sobre procesos cognitivos básicos como la atención y la memoria, se llevó a cabo un estudio de la actividad cerebral. Para llevar a cabo esta evaluación se utilizó como principal herramienta el electroencefalograma (EEG), enfocándose en los cambios producidos con y sin exposición a ruido de fondo, específicamente en las bandas de frecuencia relacionadas con procesos cognitivos básicos como los son la atención y la memoria, en este caso la banda theta (4-7 Hz) y la banda beta (13-30 Hz). ABSTRACT The interest in the study of the problem of noise in schools and its impact on students at university level is a topic that has not been properly studied. Unfortunately, there are no specific regulations for determining preventive parameters or noise assessment procedures in university facilities. Due to the importance of the effects that noise has on health and on the quality of life of university students, and consequently on academic performance; is very important to develop mechanisms to evaluate and design solutions that help ensure an improvement in the quality of life of the student population. This thesis has presented an extensive work, which includes the study of the state of the art on the problem of noise in the sound environments to which university students are exposed every day, and the effects on students mainly on attention aspects. On one hand, a general study of the common noise environments of life of university students was carried out, where a methodological proposal is included and that helps in the correct characterization of the sound environments in which university students grow. This proposal includes the assessment of noise exposure, noise dose and a recording of the characteristic sound levels during their daily activities in and out spaces dedicated to their education. Also, a survey was conducted to know the perception that students have on noise conditions in university environments. Also, a method for evaluation of the noise annoyance is proposed, this is through the correlation of two known methods of evaluation. The first method is based on psychoacoustic parameters that allow the evaluation of the sound quality. These parameters were related, obtaining as a result the parameter known as psychoacoustics annoyance. The second method is based on a questionnaire in conjunction with listening tests in specific sound environments. Derived from the correlation of these two methods, a series of indicators of noise annoyance are proposed, which entails the design of a noise annoyance indicator. Furthermore, the effects of this pollutant on psychological health and therefore in the intellectual development of students has been shown. First, an evaluation of attention and memory using standardized psychometric tests were performed and others designed for this particular study. Because it has been evidenced that the use of these psychometric tests are not very reliable, we sought to obtain another objective and reliable data to show the relationship between the negative influence of background noise on basic cognitive processes such as attention and memory. This was achieved by carrying out a study of the brain activity. To carry out this evaluation the electroencephalogram (EEG) was used as the main tool, focusing on the changes produced with and without exposure to background noise, specifically in the frequency bands related to basic cognitive processes such as attention and are memory. In this case the band theta (4-7 Hz) and beta band (13-30 Hz) were studied. The purpose of this thesis is to establish the bases for future studies that allow go deep in the study of the sound conditions in school environments, and enable the design of strategies and measures against noise and the correct evaluation of the effects of noise on aspects for improving the psychological quality of life and academic performance of students.
