3. Experience in the Use of Social Software to Support Student Learning in University Courses of Science and Engineering Degrees

Author

Díez-Pascual, Ana María, García-Díaz, Pilar, and Peña-Capilla, Rafael

Abstract

A "wiki" is an easy-to-use online tool for teachers and students, as it is a collaborative website that provides the opportunity to develop and modify its content to every member in an interactive and fast way. This paper comparatively describes experiences in the implementation of "wikis" as voluntary activities in first-year courses in a degree in Chemistry and third-year courses in a degree in Telecommunication System Engineering. The main goal of using the wikis was to achieve collaboration among students to generate knowledge. The developed methodology was applied to the resolution of exercises, problems, and test questions, as well as to the elaboration of class notes and a bilingual glossary. The approach turned the students into active learners, increasing their interest in the course contents, promoting knowledge exchange among students and encouraging the self-management of their learning process. The role of the teacher was to provide feedback to the students in order to ensure the accuracy of the contents. Four different patterns were distinguished among the students according to their participation level in the wiki. The students who were most committed to the courses were also the most involved in the "wikis", and the combination resulted in the students' success. The results obtained for the degree in Chemistry were better than those of the degree in Telecommunication System Engineering, which was ascribed to the increased connection among the first-year students. The didactic strategy was very positive, although the percentage of participation in the "wikis" was somewhat low, in particular for the third-year students, who were more independent and self-organized. Initially, the number of wiki visits increased suddenly, and then moved to a long period of lower activity in the degree of Chemistry and lethargy in the degree of Telecommunication System Engineering. Therefore, it is desirable to introduce modifications in the approach, such as flexible and consensual planning with the students in order to ensure their full engagement.

Abstract

[EN] A learning experience carried out in the first course of Engineering Degrees at the University of Alcalá is presented. The objective is to mentor, reinforce and assist in the learning process of a subject that the student should study for an extraordinary call exam when the teaching of that subject has already finished. Students usually work alone in the preparation of this evaluation and it has been demonstrated that the academic scores are on average are worse than in the ordinary call, the latter one being closer to the teaching received. A working plan has been established with pseudo-weekly supervision of a group of 70 students. All of them were volunteers. The results show a correlation between participation in the supervised group and the highest grades achieved in the evaluation, grades of "B" and "A". The coexistence of two tendencies is suggested: on the one hand, the student more committed to the subject is more likely to enroll in the mentoring group, and on the other hand, the teacher's support contributes to improve the academic achivements., [ES] Se presenta una experiencia de aprendizaje realizada en el primer curso de Grados en Ingeniería en la Universidad de Alcalá. El objetivo es guiar, reforzar y acompañar en el proceso de aprendizaje de una asignatura que el estudiante debiera prepararse para un examen de convocatoria extraordinaria cuando la docencia de dicha asignatura haya finalizado. Habitualmente los estudiantes caminan solos hacia la evaluación y los resultados académicos son peores que en la convocatoria ordinaria, próxima en el tiempo a la docencia recibida. Se ha establecido un plan de trabajo con seguimiento cuasi-semanal sobre un grupo de 70 estudiantes que participaron voluntariamente. Los resultados muestran correlación entre la participación en el grupo de seguimiento y las calificaciones más altas obtenidas en la evaluación: notable y sobresaliente. Se sugiere la coexistencia de dos tendencias: por un lado, el estudiante con mayor motivación hacia la asignatura es más proclive a incorporarse al grupo tutelado; por otro, el apoyo del docente contribuye a mejorar los logros académicos., Los autores expresan su agradecimiento al proyecto de innovación docente UAH/EV1248 de la Universidad de Alcalá, implementado por el grupo de innovación docente ABRECI (Aprendizaje Basado en Retos en Ciencias e Ingeniería, UAH-GI21-168).

Abstract

[EN] A wiki is a collaborative website that provides development and modification of its content and structure to every member in an interactive, easy and fast way. It is a simple and valuable tool for the teaching-learning process that allows both teachers and students to collaborate in the generation of knowledge. This paper describes the teaching experience in the implementation of a wiki as a voluntary activity in a practical subject of the first course of the degree in Chemistry. This methodology has been used for the elaboration of a bilingual glossary with the conceptual terms learned during the classes. The didactic strategy has been positive, although the percentage of participation in the wiki has been scarce. Only the students most committed with the subject were involved in the construction of the wiki. Therefore, it is necessary to introduce modifications in the approach of the activity in order to obtain more satisfactory results., [ES] Una wiki es un sitio web colaborativo donde sus miembros pueden crear y modificar los contenidos y su estructura de forma interactiva, fácil y rápida. Es una herramienta sencilla y valiosa para el proceso de enseñanza-aprendizaje que permite tanto a los docentes como a los alumnos colaborar en la generación de conocimiento. Este trabajo recoge la experiencia docente en la implementación de una wiki como actividad voluntaria en una asignatura práctica del primer curso del Grado en Química. Esta metodología se ha utilizado para la elaboración de un glosario bilingüe con los términos conceptuales aprendidos durante las clases presenciales. La estrategia didáctica ha resultado positiva, si bien el porcentaje de participación en la misma ha sido escaso. Solo los alumnos más comprometidos con la asignatura se involucraron en la construcción de la wiki. Por tanto, se requiere introducir modificaciones en el planteamiento de la actividad para conseguir resultados más satisfactorios.

22. A genetic algorithm for solving the first price sealed bid auction in communication networks

Subjects
Communication networks, QoS provision, Resource assignment, Auctions mechanisms, BGP protocol
Abstract

This paper shows the first result obtained in the application of economic mechanisms for the efficient assignment of resources in communication networks. The final objective is to determine which Service Provider will carry their traffic over the network of a Network Provider, which will be the most profitable route and which price the ISPs will pay for it to the Network provider. As the price is a key driver a good approach to select the ISP may be an auction mechanism. The implementation of these kind of auction mechanisms becomes a NP complete problem which is solved in this paper using novel metaheuristics, specifically a genetic algorithm.

23. Simulation of the behavior of bidders in first-price sealed-bid auctions on communication networks

Abstract

Auction mechanisms have arisen as very efficient methods for scarce resource allocations. For this reason there is a current research topic based on the application of these economics mechanisms to the design of communication networks, mainly in the provision of QoS to new multimedia services. The main research works are oriented to the assignment and pricing rules, that is, the network resource assigned to the user (the bandwidth on a link, or the route of a traffic demand) and the amount of money it is going to cost to him respectively. However, as far as we know, there is a little research focused in the analysis of the behaviour of the user. Note that an auction is in fact a competition where the user will behave selfishly in order to obtain the greater profit. In this paper we present the first results of a simulator which analyzes the behaviour of the user in an auction over a communication link. They obtain the revenue of the auctioneer that is the network provider, and the resource allocation under different schemes of user behaviour, from a very conservative character up to most risky behaviours.

Abstract

This paper presents an agent system for bandwidth allocation in reservation-based networks, using Vickrey auctions and an evolutionary algorithm. Our evolutionary approach performs the bandwidth allocation to agents which bid for networks resources by means of willingness-to-pay functions. It also calculates in a parallel way the price to be paid to the network's owner. We tackle the case of one-link, and its extension to a network. Simulations performed have shown the main advantages and problems inherent to this model [ABSTRACT FROM AUTHOR]
