Mobile and web tools for participative learning

Dissertação apresentada na Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa, para a obtenção do grau de Mestre em Engenharia InformáticaThe combination of different media formats has been a crucial aspect on teaching and learning processes. The recent developments of multimedia technologies over the Internet and using mobile devices can improve the communication between professors and students, and allow students to study anywhere and anytime, allowing each student progress at its own pace. The usage of these new platforms and the increase of multimedia sharing applied to educational environments allow a more participative learning, and make the study of interfaces a relevant aspect of existing multimedia learning systems. The work done in this dissertation explores interfaces and tools for participative learning,using multimedia educational systems over Internet broadband and mobile devices. In this work, aWeb-based learning system was developed, which enables to store, transmit, search and share the contents of courses captured in video and its extension to support Tablet PCs. The Web system, developed as part of the VideoStore project, explores video interfaces and video annotations, which encourage the participative work. The usage of Tablet PCs, through the mEmLearn project, has the aim to encourage the participative work, allowing the students to augment the course materials and to share them with other students or instructors

Automatic Lecture Recording

Lecture recording has become a very common tool to provide students with additional media for their examination preparations. While its effort has to stay reasonable, only a very basic way of recording is done in many cases. Therefore, watching the resulting videos can get very boring completely independent of how interesting the original topic or session was. This thesis proposes a new approach to lecture recordings by letting distributed computers emulate the work of a human camera team, which is the natural way of creating attractive recordings. This thesis is structured in six chapters, starting with the examination of the current situation, and taking its constraints into account. The first chapter concludes with a reflection on related work. Chapter two is about the design of our prototype system. It is deduced from a human camera team in the real world which gets transferred into the virtual world. Finally, a detailed overview about all parts necessary for our prototype and their planned functionality is given. In chapter three, the implementation of all parts and tasks and the incidents occurring during implementation are described in detail. Chapter four describes the technical experiences made with the different parts during development, testing and evaluation with a view to functionality, performance, and an proposal towards future work. The evaluation of the whole system with students is presented and discussed in the fifth chapter. Chapter six concludes this thesis by summing up the facts and gives an outlook on future work

Attributes for Australian mechanical engineers through proximal and distance education

The 1996 Johnson stakeholder review of Australian engineering education recommended the development of a number of broadly defined attributes in all engineering graduates. The Institution of Engineers, Australia (now Engineers Australia) responded swiftly by switching the focus of its engineering course accreditation requirements from course content to graduate attribute outcomes. To maximise the effectiveness of this approach to the mechanical engineering discipline a clear understanding of the relative significance of a more detailed range of attributes to Australian industry is essential, yet the scope of the mechanical engineering profession is broad and views of individual practitioners contributing to debate on attribute requirements are largely influenced by their own often unique professional formation. The research presented in this thesis is unique in using a role based analysis of the relative significance of an extensive range of attributes considered relevant to Australian mechanical engineers. The study covers the six industries found to employ the greatest number of Australian mechanical engineers. The significance of these attributes in the core mechanical engineering roles of each industry are weighted according to the numbers of mechanical engineers employed in those roles. These attribute significance profiles are considered in the context of a study of the formative development of the profession under the extensive influence of 19th and 20th century UK and US practices and recent momentous changes in engineering employment and formation. A wide range of appropriate teaching strategies to develop the most significant attributes through proximal and distance learning are explored and a brief account of the candidate’s work in developing and assessing the use of technology to enhance flexible learning in the field of engineering education is also included in this thesis. Whilst major areas of the mechanical engineers knowledge base are considered as part of the main study, further case study based research is presented to assess in more detail the knowledge base requirements for Australia’s best performing manufacturing industry by ‘industry value added’ - Food, Beverage and Pharmaceuticals and as such provides an indication of the relevance of the content base of Australian mechanical (as well as chemical and electrical) engineering degree programs to an Australian industry sector
