Hyvää yhteisöllistä verkko-oppimista jäljittämässä. Neljän virtuaalisen kirjallisuuskeskustelun sisällönanalyysi

Tutkimuksessa etsittiin hyvää yhteisöllistä verkko-oppimista (Computer Supported Collaborative Learning, CSCL) lukiolaisten kirjallisuuskeskusteluista. Tavoitteena oli hankkia tietoa virtuaalisista kirjallisuuskeskusteluista yhteisöllisenä, vuorovaikutuksellisena oppimisen muotona. Tutkimus sijoittuu osaksi kansainvälistä Tutkivan yhteisön (Community of Inquiry, CoI) tutkimusperinnettä ja se käyttää Neil Mercerin kielen ja ajattelun yhdistävää ajatteluyhteisön (thinking community) perinnettä. Uutta oli kaikkien CoI-malliin liittyvien kolmen oppimiseen liittyvän näkökulman, kognitiivisen, sosiaalisen ja ohjauksellisen arvioiminen kaunokirjallisuusaiheisessa verkkokeskustelussa ja kielellisen tarkastelun yhdistäminen siihen. Lähestymistapa oli sosiokulttuurinen ja sosiokonstruktivistinen. Tutkimusaineistona oli vuosina 2003 ja 2004 keskisuuren kaupungin kolmen lukion 16 oppilaan, yhden opettajan ja yhden kirjastonhoitajan käymät neljä keskimäärin 5 hengen kirjallisuuspiirikeskustelua. Tutkimusmenetelminä käytettiin sekä laadullista että määrällistä sisällönanalyysia. Tuloksena oli, että osallistujat kirjoittivat keskimäärin 5,2 dialogivuoroa. Yhteen keskusteluun otti aktiivisesti osaa kolme osallistujaa. Sosiaalinen läsnäolo oli vahvaa kaikissa keskusteluissa. Tunnepitoisia ilmauksia käytettiin keskustelun kohteesta, kirjasta. Keskusteluille oli tyypillistä viestinnän avoimuus, ja keskinäistä tietoisuutta ilmennettiin paljon. Erityisen runsasta sosiaalinen läsnäolo oli toisensa tuntevien tyttöjen vertaiskeskustelussa. Pojat toimivat keskusteluissa keskustelun kyseenalaistajina, mutta samalla terävöittivät keskustelua tehtävän suuntaisesti. Sosiaalista läsnäolon osatekijöistä erityisesti itsekunnioitus ja ryhmäyhtenäisyys yhdistyivät kognitiivisen läsnäolon näkymiseen. Kognitiivinen läsnäolo oli vahvempaa niissä keskusteluissa, joissa ohjaaja oli mukana, kuin oppilaiden vertaiskeskusteluissa. Kirjallisuustieteen näkökulmasta tietoa rakennettiin parhaiten keskustelussa, jossa ohjauksellista läsnäoloa loi äidinkielenopettaja ja jossa luettu kaunokirjallinen teos oli sopivan arvoituksellinen. Tuloksena oli myös, että ohjaajan kannattaa välttää liian aikaista keskusteluun mukaan tuloa. Silloin oppilasryhmä pyrkii mahdollisimman kauan itse älyllisiin päättelyihin. Tutkimuksessa käytettyjen keskustelun arvioimisen tapojen avulla voidaan tulevaisuudessa kouluissa arvioida, miten hyvä ja yhteisöllinen oma verkkokeskustelu on ollut.

Knowledge Building in Landscape Architecture

The objective of this study was to develop an internet-based seminar framework applicable for landscape architecture education. This process was accompanied by various aims. The basic expectation was to keep the main characteristics of landscape architecture education also in the online format. On top of that, four further objectives were anticipated: (1) training of competences for virtual team work, (2) fostering intercultural competence, (3) creation of equal opportunities for education through internet-based open access and (4) synergy effects and learning processes across institutional boundaries. This work started with the hypothesis that these four expected advantages would compensate for additional organisational efforts caused by the online delivery of the seminars and thus lead to a sustainable integration of this new learning mode into landscape architecture curricula. This rationale was followed by a presentation of four areas of knowledge to which the seminar development was directly related (1) landscape architecture as a subject and its pedagogy, (2) general learning theories, (3) developments in the ICT sector and (4) wider societal driving forces such as global citizenship and the increase of open educational resources. The research design took the shape of a pedagogical action research cycle. This approach was constructive: The author herself is teaching international landscape architecture students so that the model could directly be applied in practice. Seven online seminars were implemented in the period from 2008 to 2013 and this experience represents the core of this study. The seminars were conducted with varying themes while its pedagogy, organisation and the technological tools remained widely identical. The research design is further based on three levels of observation: (1) the seminar design on the basis of theory and methods from the learning sciences, in particular educational constructivism, (2) the seminar evaluation and (3) the evaluation of the seminars’ long term impact. The seminar model itself basically consists of four elements: (1) the taxonomy of learning objectives, (2) ICT tools and their application and pedagogy, (3) process models and (4) the case study framework. The seminar framework was followed by the presentation of the evaluation findings. The major findings of this study can be summed up as follows: Implementing online seminars across educational and national boundaries was possible both in term of organisation and technology. In particular, a high level of cultural diversity among the seminar participants has definitively been achieved. However, there were also obvious obstacles. These were primarily competing study commitments and incompatible schedules among the students attending from different academic programmes, partly even in different time zones. Both factors had negative impact on the individual and working group performances. With respect to the technical framework it can be concluded that the majority of the participants were able to use the tools either directly without any problem or after overcoming some smaller problems. Also the seminar wiki was intensively used for completing the seminar assignments. However, too less truly collaborative text production was observed which could be improved by changing the requirements for the collaborative task. Two different process models have been applied for guiding the collaboration of the small groups and both were in general successful. However, it needs to be said that even if the students were able to follow the collaborative task and to co-construct and compare case studies, most of them were not able to synthesize the knowledge they had compiled. This means that the area of consideration often remained on the level of the case and further reflections, generalisations and critique were largely missing. This shows that the seminar model needs to find better ways for triggering knowledge building and critical reflection. It was also suggested to have a more differentiated group building strategy in future seminars. A comparison of pre- and post seminar concept maps showed that an increase of factual and conceptual knowledge on the individual level was widely recognizable. Also the evaluation of the case studies (the major seminar output) revealed that the students have undergone developments of both the factual and the conceptual knowledge domain. Also their self-assessment with respect to individual learning development showed that the highest consensus was achieved in the field of subject-specific knowledge. The participants were much more doubtful with regard to the progress of generic competences such as analysis, communication and organisation. However, 50% of the participants confirmed that they perceived individual development on all competence areas the survey had asked for. Have the additional four targets been met? Concerning the competences for working in a virtual team it can be concluded that the vast majority was able to use the internet-based tools and to work with them in a target-oriented way. However, there were obvious differences regarding the intensity and activity of participation, both because of external and personal factors. A very positive aspect is the achievement of a high cultural diversity supporting the participants’ intercultural competence. Learning from group members was obviously a success factor for the working groups. Regarding the possibilities for better accessibility of educational opportunities it became clear that a significant number of participants were not able to go abroad during their studies because of financial or personal reasons. They confirmed that the online seminar was to some extent a compensation for not having been abroad for studying. Inter-institutional learning and synergy was achieved in so far that many teachers from different countries contributed with individual lectures. However, those teachers hardly ever followed more than one session. Therefore, the learning effect remained largely within the seminar learning group. Looking back at the research design it can be said that the pedagogical action research cycle was an appropriate and valuable approach allowing for strong interaction between theory and practice. However, some more external evaluation from peers in particular regarding the participants’ products would have been valuable.

Profundizar en el estudio y desarrollo de modelos de soporte para el aprendizaje colaborativo a distancia, que permite proponer una arquitectura fundamentada en los principios del paradigma CSCL (Computer Supported Collaborative Learning). La arquitectura propuesta aborda un tipo de problema concreto que requiere el uso de técnicas derivadas del trabajo colaborativo, la inteligencia artificial, interfaces de usuario así como ideas tomadas de la Pedagogía y la Psicología. Se diseña una solución completa, abierta y genérica. La arquitectura aprovecha las nuevas tecnologías para lograr un sistema efectivo de apoyo a la educación a distancia. Se organiza en cuatro niveles: el de Configuración, el de Experiencia, el de Organización y el de Análisis. A partir de ella se implementa un sistema llamado Degree. En Degree, cada uno de los niveles de la arquitectura da lugar a un subsistema independiente pero relacionado con los otros. La aplicación saca partido del uso de espacios de trabajo estructurados. El subsistema Configurador de Experiencias permite definir los elementos de un espacio de trabajo y una experiencia y adaptarlos a cada tipo de usuario. El subsistema Manejador de Experiencias recoge las contribuciones de los usuarios para construir una solución conjunta de un problema. Las intervenciones de los alumnos se estructuran basándose en un grafo conversacional genérico.

SAACI : sistema de apoio à aprendizagem colaborativa na internet

O atual contexto social tem sido marcado pelo constante avanço tecnológico e científico, pela rápida defasagem dos conhecimentos e pela demanda por profissionais mais qualificadas e capazes de aprender e resolver problemas colaborativamente. A fim de atender esta demanda, o ensino tradicional tem que mudar, de forma que as pessoas possam desenvolver habilidades de “aprender a aprender” e “aprender colaborativamente”. A Aprendizagem Colaborativa tem sido apontada como uma alternativa a este problema, possibilitando uma aprendizagem flexível, ativa e centrada no aluno. Os alunos aprendem em colaboração com outros alunos, o que possibilita uma aprendizagem mais profunda, através de trocas de idéias, dúvidas e pontos de vista. Por outro lado, o advento da rede Internet e a consolidação desta como um importante meio de comunicação mundial têm introduzido novas possibilidades à Aprendizagem Colaborativa Apoiada por Computador (Computer Supported Collaborative Learning – CSCL). Uma atenção especial tem sido dada ao WWW, serviço que possui grande potencial como meio ativo de aprendizagem, embora seja amplamente utilizado como meio passivo de transmissão de informações pela Internet. Este cenário tem viabilizado a utilização da infra-estrutura da Internet para a criação de um sistema de CSCL de grande alcance e a um custo relativamente baixo. O objetivo principal do presente trabalho é propor e implementar um modelo de CSCL baseado na Internet que forneça, de forma integrada, o suporte necessário para o desenvolvimento efetivo de atividades colaborativas de aprendizagem. O trabalho realizado pode ser dividido em três etapas principais: (1) o levantamento teórico, que consistiu no estudo das principais áreas relacionadas com o trabalho desenvolvido, o que foi fundamental para a definição do modelo de sistema de aprendizagem colaborativa proposto; (2) a definição do modelo, que consistiu no levantamento das atividades básicas que devem ser apoiadas por um ambiente de CSCL e na proposição do modelo de um sistema de CSCL baseado na Internet com suporte às atividades levantadas; (3) a implementação do modelo, que possibilitou a verificação da viabilidade da utilização do serviço WWW como base para um ambiente de CSCL, através da utilização de recursos de programação para web e da integração de ferramentas já existentes na Internet.

Logger : agente de colaboração em um ambiente de aprendizagem utilizando software livre no apoio à educação a distância

O Ensino Colaborativo suportado por Computador, conhecido por CSCL (Computer Supported Collaborative Learning), utiliza-se de uma metodologia de ensino em que os alunos trocam idéias sobre assuntos que foram previamente pesquisados. O professor tem a função de moderador onde incentiva e orienta os alunos no processo de aprendizagem através da criação de cenários para motivação dos mesmos, sugerindo artigos e direcionando-os para os pontos mais importantes de cada assunto. Entretanto, para que se possa buscar uma interação apropriada entre o aluno e o ambiente de aprendizagem, se faz necessária à utilização de ferramentas que propiciem um maior controle sobre o sistema, permitindo assim, a monitoração das tarefas executadas pelo usuário, podendo direcioná-lo de forma correta na busca do aprendizado interativo. Busca-se, através deste trabalho, subsidiar o estudo de Lachi, permitindo a monitoração das ações através de um agente de colaboração, nos horários de aulas prédeterminados e fora destes horários, mantendo informações sobre a freqüência das interações realizadas e permitindo uma melhor orientação pelo responsável das atividades a serem executadas pelos alunos, através da captura das conversações realizadas num ambiente de Educação a Distância que utiliza Software Livre, o qual como resultado final proporcionará a análise das conversações com aplicação de um algoritmo de best search pelo professor, das ações dos participantes, no qual foi proposto por Lachi e agora implementamos parcialmente.

The proposed architecture addresses a specific problem: coordinating groups of students to perform collaborative distance learning activities. Our approach uses Cooperative Work, Artificial Intelligence and Human-Computer Interaction techniques as well as some ideas from the fields of Pedagogy and Psychology. We have designed a complete, open and generic solution. Our architecture exploits the new information technologies to achieve an effective system for education purposes. It is organised into four levels: Configuration, Experience, Organisation and Reflection. This model has been implemented into a system called DEGREE. In DEGREE, each level of the architecture gives rise to an independent subsystem related to the other ones. The application benefits from the use of shared structured workspaces. The configuration subsystem allows customising the elements that define an experience and a workspace. The experience subsystem gathers the users' contributions to build joint solutions to a given problem. The students' interventions build up a structure based on a generic conversation graph. Moreover, all user actions are registered in order to represent explicitly the complete process for reaching the group solution. Those data are also stored into a common memory, which constitutes the organisation subsystem. The user interventions are studied by the reflection subsystem. This analysis allows us inferring conclusions about the way in which the group works and its attitudes towards collaboration. The inference process takes into account the observer's subjective knowledge. The process of developing both the architecture and the system in parallel has run through a five-pass cycle involving successive stages of prototyping and formative evaluation. At each stage of that process, we have considered the users' feedback for improving the architecture's functionalities as well as the system interface. This approach has allowed us to prove the usability and validity of our proposal.

ReaderBench goes Online: A Comprehension-Centered Framework for Educational Purposes

In this paper we introduce the online version of our ReaderBench framework, which includes multi-lingual comprehension-centered web services designed to address a wide range of individual and collaborative learning scenarios, as follows. First, students can be engaged in reading a course material, then eliciting their understanding of it; the reading strategies component provides an in-depth perspective of comprehension processes. Second, students can write an essay or a summary; the automated essay grading component provides them access to more than 200 textual complexity indices covering lexical, syntax, semantics and discourse structure measurements. Third, students can start discussing in a chat or a forum; the Computer Supported Collaborative Learning (CSCL) component provides indepth conversation analysis in terms of evaluating each member’s involvement in the CSCL environments. Eventually, the sentiment analysis, as well as the semantic models and topic mining components enable a clearer perspective in terms of learner’s points of view and of underlying interests.

Discovering the campus together: a mobile and computer-based learning experience

One of the most relevant difficulties faced by first-year undergraduate students is to settle into the educational environment of universities. This paper presents a case study that proposes a computer-assisted collaborative experience designed to help students in their transition from high school to university. This is done by facilitating their first contact with the campus and its services, the university community, methodologies and activities. The experience combines individual and collaborative activities, conducted in and out of the classroom, structured following the Jigsaw Collaborative Learning Flow Pattern. A specific environment including portable technologies with network and computer applications has been developed to support and facilitate the orchestration of a flow of learning activities into a single integrated learning setting. The result is a Computer-Supported Collaborative Blended Learning scenario, which has been evaluated with first-year university students of the degrees of Software and Audiovisual Engineering within the subject Introduction to Information and Communications Technologies. The findings reveal that the scenario improves significantly students’ interest in their studies and their understanding about the campus and services provided. The environment is also an innovative approach to successfully support the heterogeneous activities conducted by both teachers and students during the scenario. This paper introduces the goals and context of the case study, describes how the technology was employed to conduct the learning scenario, the evaluation methods and the main results of the experience.

Collaborative learning in a qeb-accessible workbench

Web-based course management and delivery is regarded by many institutions as a key factor in an increasingly competitive education and training world, but the systems currently available are largely unsatisfactory in terms of supporting collaborative work and access to practical science facilities. These limitations are less important in areas where “pen-and-paper” courseware is the mainstream, but become unacceptably restrictive when student assignments require real-time teamwork and access to laboratory equipment. This paper presents a web-accessible workbench for electronics design and test, which was developed in the scope of an European IST project entitled PEARL, with the aim of supporting two main features: full web access and collaborative learning facilities.
