Blended learning approach to include the innovative use of vodcasts (video-podcasts) to enrich students learning experience in structures laboratory

Students may have difficulty in understanding some of the complex concepts which they have been taught in the general areas of science and engineering. Whilst practical work such as a laboratory based examination of the performance of structures has an important role in knowledge construction this does have some limitations. Blended learning supports different learning styles, hence further benefits knowledge building. This research involves the empirical studies of how an innovative use of vodcasts (video-podcasts) can enrich learning experience in the structural properties of materials laboratory of an undergraduate course. Students were given the opportunity of downloading and viewing the vodcasts on the theory before and after the experimental work. It is the choice of the students when (before or after, before and after) and how many times they would like to view the vodcasts. In blended learning, the combination of face-to-face teaching, vodcasts, printed materials, practical experiments, writing reports and instructors’ feedbacks benefits different learning styles of the learners. For the preparation of the practical laboratory work, the students were informed about the availability of the vodcasts prior to the practical session. After the practical work, students submit an individual laboratory report for the assessment of the structures laboratory. The data collection consists of a questionnaire completed by the students, and the practical reports submitted by them for assessment. The results from the questionnaire were analysed quantitatively, whilst the data from the assessment reports were analysed qualitatively. The analysis shows that students who have not fully grasped the theory after the practical were successful in gaining the required knowledge by viewing the vodcasts. Some students who have understood the theory may choose to view it once or not at all. Their understanding was demonstrated by the quality of their explanations in their reports. This is illustrated by the approach they took to explicate the results of their experimental work, for example, they can explain how to calculate the Young’s Modulus properly and provided the correct value for it. The research findings are valuable to instructors who design, develop and deliver different types of blended learning, and beneficial to learners who try different blended approaches. Recommendations were made on the role of the innovative application of vodcasts in the knowledge construction for structures laboratory and to guide future work in this area of research.

Effective e-learning integration with traditional learning in a blended learning environment

E-Learning is an emerging tool that uses advanced technology to provide training and development in higher education and within industry. Its rapid growth has been facilitated by the Internet and the massive opportunities in global education. The aim of this study is to consider how effective and efficient e-learning is when integrated with traditional learning in a blended learning environment. The study will provide a comparison between purist ELearning and Blended learning environment. The paper will also provide directions for the blended learning environment which can be used by all the three main stakeholder student, tutors and institution to make strategic decision about the learning and teaching initiatives. The paper concludes that blended learning approaches offer the most flexible and scalable route to E-Learning.

Model-based groupware solution for distributed real-time collaborative 4D planning via teamwork

Construction planning plays a fundamental role in construction project management that requires team working among planners from a diverse range of disciplines and in geographically dispersed working situations. Model-based four-dimensional (4D) computer-aided design (CAD) groupware, though considered a possible approach to supporting collaborative planning, is still short of effective collaborative mechanisms for teamwork due to methodological, technological and social challenges. Targeting this problem, this paper proposes a model-based groupware solution to enable a group of multidisciplinary planners to perform real-time collaborative 4D planning across the Internet. In the light of the interactive definition method, and its computer-supported collaborative work (CSCW) design analysis, the paper discusses the realization of interactive collaborative mechanisms from software architecture, application mode, and data exchange protocol. These mechanisms have been integrated into a groupware solution, which was validated by a planning team in a truly geographically dispersed condition. Analysis of the validation results revealed that the proposed solution is feasible for real-time collaborative 4D planning to gain a robust construction plan through collaborative teamwork. The realization of this solution triggers further considerations about its enhancement for wider groupware applications.

The impacts of learning styles, learning patterns and demographic factors on learners’ performance in a blended learning environment

Many studies have widely accepted the assumption that learning processes can be promoted when teaching styles and learning styles are well matched. In this study, the synergy between learning styles, learning patterns, and gender as a selected demographic feature and learners’ performance were quantitatively investigated in a blended learning setting. This environment adopts a traditional teaching approach of ‘one-sizefits-all’ without considering individual user’s preferences and attitudes. Hence, evidence can be provided about the value of taking such factors into account in Adaptive Educational Hypermedia Systems (AEHSs). Felder and Soloman’s Index of Learning Styles (ILS) was used to identify the learning styles of 59 undergraduate students at the University of Babylon. Five hypotheses were investigated in the experiment. Our findings show that there is no statistical significance in some of the assessed factors. However, processing dimension, the total number of hits on course website and gender indicated a statistical significance on learners’ performance. This finding needs more investigation in order to identify the effective factors on students’ achievement to be considered in Adaptive Educational Hypermedia Systems (AEHSs).

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.

Collaborative language learning in Teletandem: a resource for pre-service teacher education

This article presents some of the results of a qualitative research project about the influences of the pedagogic strategies used by a mediator (graduate student in applied linguistics) in the supervision process of a Teletandem partner (undergraduate student in languages) on her pedagogical practice. It was done within the project Teletandem Brazil: foreign language for all. Based on the reflective teaching paradigm and collaborative language learning, with special emphasis on tandem learning, we analyzed the contributions of the collaborative relationship established between the graduate student and the student-teacher in her first teaching experience. The results bring about implications for the field of language teacher education in a perspective of education within practice, evidencing the experience of collaborative learning in teletandem as an opportunity for reflective teacher education of pre-service teachers.
