An Empirical Study on Faculty Perceptions and Teaching Practices of Wikipedia

Some faculty members from different universities around the world have begun to use Wikipedia as a teaching tool in recent years. These experiences show, in most cases, very satisfactory results and a substantial improvement in various basic skills, as well as a positive influence on the students' motivation. Nevertheless and despite the growing importance of e-learning methodologies based on the use of the Internet for higher education, the use of Wikipedia as a teaching resource remains scarce among university faculty.Our investigation tries to identify which are the main factors that determine acceptance or resistance to that use. We approach the decision to use Wikipedia as a teaching tool by analyzing both the individual attributes of faculty members and the characteristics of the environment where they develop their teaching activity. From a specific survey sent to all faculty of the Universitat Oberta de Catalunya (UOC), pioneer and leader in online education in Spain, we have tried to infer the influence of these internal and external elements. The questionnaire was designed to measure different constructs: perceived quality of Wikipedia, teaching practices involving Wikipedia, use experience, perceived usefulness and use of 2.0 tools. Control items were also included for gathering information on gender, age, teaching experience, academic rank, and area of expertise.Our results reveal that academic rank, teaching experience, age or gender, are not decisive factors in explaining the educational use of Wikipedia. Instead, the decision to use it is closely linked to the perception of Wikipedia's quality, the use of other collaborative learning tools, an active attitude towards web 2.0 applications, and connections with the professional non-academic world. Situational context is also very important, since the use is higher when faculty members have got reference models in their close environment and when they perceive it is positively valued by their colleagues. As far as these attitudes, practices and cultural norms diverge in different scientific disciplines, we have also detected clear differences in the use of Wikipedia among areas of academic expertise. As a consequence, a greater application of Wikipedia both as a teaching resource and as a driver for teaching innovation would require much more active institutional policies and some changes in the dominant academic culture among faculty members.

Research and teaching: a holy or an unholy alliance?

Much of the self-image of the Western university hangs on the idea that research and teaching are intimately connected. The central axiom here is that research and teaching are mutually supportive of each other. An institution lacking such a set of relationships between research and teaching falls short of what it means to be a university. This set of beliefs raises certain questions: Is it the case that the presence of such a mutually supportive set of relationships between research and teaching is a necessary condition of the fulfilment of the idea of the university? (A conceptual question). And is it true that, in practice today, such a mutually supportive set of relationships between research and teaching characterises universities? (An empirical question). In my talk, I want to explore these matters in a critical vein. I shall suggest that: a) In practice today, such a mutually supportive set of relationships between research and teaching is in jeopardy. Far from supporting each other, very often research and teaching contend against each other. Research and teaching are becoming two separate ideologies, with their own interest structures. b) Historically, the supposed tight link between research and teaching is both of recent origin and far from universally achieved in universities. Institutional separateness between research and teaching is and has been evident, both across institutions and even across departments in the same institution. c) Conceptually, research and teaching are different activities: each is complex and neither is reducible to the other. In theory, therefore, research and teaching may be said to constitute a holy alliance but in practice, we see more of an unholy alliance. If, then, in an ideal world, a positive relationship between research and teaching is still a worthwhile goal, how might it be construed and worked for? Seeing research and teaching as two discrete and unified sets of activity is now inadequate. Much better is a construal of research and teaching as themselves complexes, as intermingling pools of activity helping to form the liquid university that is emerging today. On this view, research and teaching are fluid spaces, ever on the move, taking up new shapes, and themselves dividing and reforming, as the university reworks its own destiny in modern society. On such a perspective, working out a productive relationship between research and teaching is a complex project. This is an alliance that is neither holy nor unholy. It is an uneasy alliance, with temporary accommodations and continuous new possibilities.

Correcció d'exercicis de lògica per l'ACME

La Universitat de Girona, i més concretament el Departament d’Informàtica i Matemàtica Aplicada, ja fa uns anys que ha posat en marxa el Projecte Avaluació Continuada i Millora de l’Ensenyament, també anomenat ACME. Aquest projecte és una plataforma d'e-learning, és a dir, un sistema d’aprenentatge a través de la xarxa que potencia la col•laboració digital i el bescanvi d’informació entre alumne i professor. El creixement que ha experimentat la plataforma, ha estat possible gràcies al disseny modular de l’aplicació, on cada nova funcionalitat que estava essent desenvolupada evolucionava de manera independent a la resta de la plataforma i sense comprometre’n el funcionament. Per afegir un nou mòdul a l’ACME, s’utilitzen els mòduls de base que confereixen l'estructura a la plataforma i les eines per incorporar nous mòduls, amb el que la implantació d’aquests a la plataforma és d’elevada senzillesa. Actualment, la majoria de les assignatures de primer del Grau d’Informàtica ja disposen d’exercicis adaptats a la plataforma, el que dóna una uniformitat en les eines i plataformes que utilitzen els alumnes en la seva formació. Però no hi són totes les assignatures, falta incloure l’assignatura de Lògica a la plataforma. D’aquesta manera, tant els alumnes com els professors de l’assignatura, podran treure profit dels beneficis esmentats que aporta l’ACME. Concretament, a l’assignatura de Lògica es disposava d’uns aplicatius a la plataforma Moodle de la Universitat de Girona on es guiava a l’alumne en la resolució dels exercicis. Aquest mètode és molt interessant com a mètode pedagògic per a l’aprenentatge inicial de l’assignatura, però no representa un repte real on els alumnes hagin d’aplicar els seus coneixements per a la seva realització. Els alumnes també disposaven d’un dossier on se’ls proposava uns exercicis molt complets, i a les pàgines finals d’aquest se’ls donava la solució. Aleshores, de manera voluntària els alumnes realitzaven els exercicis i comprovaven amb la solució si havien aprés a resoldre’ls. Per tant, tant els responsables de l'assignatura de Lògica com els responsables de la plataforma ACME van veure que es podrien desenvolupar eines a l'ACME per tal de corregir de forma automàtica els exercicis de l'assignatura. Incorporar l’assignatura de Lògica a l’ACME permet que els alumnes es vegin més involucrats a fer exercicis durant els curs de manera continuada, gràcies als terminis d’entrega, i facilita als professors la seva tasca deslliurant-los de les correccions i oferint-los-hi eines de seguiment

A Variant of Higher-Order Anti-Unification

We present a rule-based Huet’s style anti-unification algorithm for simply-typed lambda-terms in ɳ long β normal form, which computes a least general higher-order pattern generalization. For a pair of arbitrary terms of the same type, such a generalization always exists and is unique modulo α equivalence and variable renaming. The algorithm computes it in cubic time within linear space. It has been implemented and the code is freely available

An Efficient Nominal Unification Algorithm

Nominal Unification is an extension of first-order unification where terms can contain binders and unification is performed modulo α equivalence. Here we prove that the existence of nominal unifiers can be decided in quadratic time. First, we linearly-reduce nominal unification problems to a sequence of freshness and equalities between atoms, modulo a permutation, using ideas as Paterson and Wegman for first-order unification. Second, we prove that solvability of these reduced problems may be checked in quadràtic time. Finally, we point out how using ideas of Brown and Tarjan for unbalanced merging, we could solve these reduced problems more efficiently

A Write-Based Solver for SAT Modulo the Theory of Arrays

The extensional theory of arrays is one of the most important ones for applications of SAT Modulo Theories (SMT) to hardware and software verification. Here we present a new T-solver for arrays in the context of the DPLL(T) approach to SMT. The main characteristics of our solver are: (i) no translation of writes into reads is needed, (ii) there is no axiom instantiation, and (iii) the T-solver interacts with the Boolean engine by asking to split on equality literals between indices. As far as we know, this is the first accurate description of an array solver integrated in a state-of-the-art SMT solver and, unlike most state-of-the-art solvers, it is not based on a lazy instantiation of the array axioms. Moreover, it is very competitive in practice, specially on problems that require heavy reasoning on array literals

Marketing education, distance learning and hypermedia : teaching 'current issues in marketing' in a virtual campus

This article reports on a project at the Universitat Oberta de Catalunya (UOC: The Open University of Catalonia, Barcelona) to develop an innovative package of hypermedia-based learning materials for a new course entitled 'Current Issues in Marketing'. The UOC is a distance university entirely based on a virtual campus. The learning materials project was undertaken in order to benefit from the advantages which new communication technologies offer to the teaching of marketing in distance education. The article reviews the main issues involved in incorporating new technologies in learning materials, the development of the learning materials, and their functioning within the hypermedia based virtual campus of the UOC. An empirical study is then carried out in order to evaluate the attitudes of students to the project. Finally, suggestions for improving similar projects in the future are put forward.

Early Childhood Mathematics Education: Research, Curriculum and Educational Practice

This article reviews data obtained through research into early childhood mathematics education in Spain. It analyses the current curricular directions in mathematics education with early learners. It also provides an overview of mathematical practices in early childhood education classrooms to analyse the commonalities and differences between research, curriculum and educational practice. A review of the research presented at SEIEM symposia from 1997 until 2012 demonstrates: a) very little research has been done, a trend that is repeated in other areas, such as the JCR-Social Sciences Edition or the PME; b) the first steps have been taken to create a more and more cohesive body of research, although until now there has not been enough data to outline the curricular directions; and c) some discrepancies still exist between the mathematical practices in early childhood education classrooms and the official guidelines

We offer a didactic proposal about conflict and explain the results of its application intwo Secondary Education classrooms

Schooling in the Network Society : Internet in Primary and Secondary Education. Research report (synthesis document)

Aquest projecte té la intenció d'identificar i analitzar els efectes de la introducció d'Internet a les escoles catalanes (educació primària i secundària). L'objectiu és posar de manifest la manera com s'utilitza la xarxa en aquest àmbit i en quina mesura contribueix a l'aparició, en els centres educatius, d'una nova cultura adaptada a les necessitats de la societat xarxa. Amb aquest propòsit, aquest projecte desplega les seves línies d'anàlisi per a fer atenció al procés d'incorporació d'Internet, principalment, en tres direccions: la pràctica pedagògica, les formes d'organització i gestió dels centres educatius i la seva vinculació amb la comunitat i el territori. Aquesta investigació ha estat desenvolupada pel grup de recerca ENS (Education and Network Society). Amb una perspectiva comparativa, el treball d'aquest grup vol contribuir, sobre la base de dades empíriques, a interpretar la transformació de l'àmbit educatiu no universitari en els paràmetres que estableix, avui dia, la nostra societat.

Engaging students in an e-learning experience : how to manage information resources through wikis and web blogs

The purpose of this paper is to describe the collaboration between librarians and scholars, from a virtual university, in order to facilitate collaborative learning on how to manage information resources. The personal information behaviour of e-learning students when managing information resources for academic, professional and daily life purposes was studied from 24 semi-structured face-to-face interviews. The results of the content analysis of the interview' transcriptions, highlighted that in the workplace and daily life contexts, competent information behaviour is always linked to a proactive attitude, that is to say, that participants seek for information without some extrinsic reward or avoiding punishment. In the academic context, it was observed a low level of information literacy and it seems to be related with a prevalent uninvolved attitude.

Teaching, research and service: Experience and opinions of accounting Spanish academics

Research, teaching and service are the main activities carried out in almost all European universities. Previous research, which has been mainlycentred in North-American universities, has found solid results indicatingthat research and teaching are not equally valued when deciding on facultypromotion. This conclusion creates a potential conflict for accountingacademics on how to distribute working time in order to accomplish personalcareer objectives. This paper presents the results of a survey realisedin two European countries: Spain and the United Kingdom, which intendedto explore the opinions and personal experience of accounting academicsworking in these countries. Specifically, we focus on the following issues:(i) The impact of teaching and service on time available for research;(ii) The integration of teaching and research; (iii) The perceived valueof teaching and research for career success and (iv) The interaction betweenprofessional accounting and accounting research. The results show thatboth in Spain and in the United Kingdom there is a conflict between teachingand research, which has its origin in the importance attached to researchactivities on promotion decisions. It also seems evident that so far, theconflict is being solved in favour of research in prejudice of teaching.

Using Songs in Primary Education: Advantages and Challenges

Aquesta recerca està basada en l’observació de les cançons per aprendre i ensenyar la llengua anglesa en l’etapa d’Educació Primària. S’analitza la cançó com un recurs eficaç per aprendre aquesta llengua, així com també s’observen els avantatges i desavantatges que es poden trobar en l’ús de les cançons a les aules de Primària. A partir d’una aplicació pràctica també s’estudia la validesa d’aquest recurs en el primer i darrer curs de la Primària. A més a més, es mesura la motivació que mostren els alumnes davant d’aquesta eina d’aprenentatge. Finalment, es presenten els resultats obtinguts en l’aplicació pràctica que s’ha portat a terme en una escola i les conclusions que s’extreuen a partir de la justificació teòrica i els resultats obtinguts a partir de les sessions pràctiques.
