The aim of this thesis is to provide academic support to the oldest discipline of Mechanical Engineering, namely "Machine Design". The rapid pace of technological development drives every individual, especially students. The industrial revolution in the first half of the 19th century contributed greatly to the advancement of Mechanical Engineering. The theories and experimental data from that time, some developed almost a hundred years ago are still in use in the original form while others have evolved to keep up with the times. This thesis attempts to bring some of that classical machine design theory into a modern user-friendly form that is portable across the Internet. Here the user will be presented with an interactive menu of topics of Machine Design where each is split sub-categorically as Theory and Application. According to the choice made, short excerpts of theory are presented on the chosen matter. The theory will include but not be limited to the important relationships relevant to the design of the particular machine element. After the review of the Theory, the user will be able to navigate to the application where the relationships from the theory will be awaiting user input in the form of solvers. Since the primary emphasis of the thesis is about cultivating knowledge of the underlying theory, the applications will not be self-correcting or self-assuming. The user will need to understand the relationships sufficiently well prior to using the applications to solve homework or design assignments. The created Toolbox is available to all registered users through a login access. The user can then choose to review theory or directly access the applications of the described theory. The thesis successfully demonstrates the use of the Internet as the media for education. / Master of Science

The purpose of this study is to determine the impact on student use of electronic information systems when teachers have been given instruction on their use. By providing teachers with a solid introduction to the technology, a handy reference book, and an easy-to-use evaluation tool, it is expected that they will incorporate information found on the internet into their lessons at least twice a month. In addition, teachers will allow students to access information on their own, provided computers and Internet access are available, at least once a month.

Essa arquitetura suporta os processos de criação e conversão do conhecimento, com ênfase na identificação de conhecimentos tácitos de seus usuários. Além disso, discute-se como um sistema de suporte ao GC, desenvolvido com base na arquitetura proposta, pode ser aplicado a fins educacionais. O trabalho descreve os passos seguidos para a definição da arquitetura, detalhando as etapas de modelagem e projeto. Ao final, apresenta-se como exemplo um sistema que segue as especificações da arquitetura e discutem-se os resultados obtidos através da utilização do mesmo em um laboratório de pesquisas acadêmicas / Abstract: This work proposes an architecture of knowledge management (KM) support, that can serve as a base to build systems for this type of application. This architecture supports the processes of knowledge creation and conversion, with emphasis in the identification of tacit knowledge of its users. Moreover, it is discussed how a knowledge management support system, developed according to the proposed architecture, can be used for educational applications. The work describes the steps followed for the definition of the architecture, detailing the stages of modeling and design. At the end, an example system is presented, following the specifications of the architecture, and its use in a laboratory of academic research is discussed. / Mestrado / Engenharia de Computação / Mestre em Engenharia Elétrica

The poor performance by South African pupils in The Third International Mathematics and Science Study highlighted the importance of and need for Continuing Professional Development (CPD) for South African mathematics teachers. For these teachers, the sudden, rapid and dramatic advent of the World Wide Web (WWW) and its communication conduit, the Internet, with its multimedia capabilities, interactive tools and telecommunication facilities, seems full of potential as a catalyst for significant and sustained online CPD activities. However, the Internet's usefulness for mathematics and spontaneous mathematical interaction is severely limited. Against this background, the motivation for this study was born out of two beliefs - a belief that context needs to be considered in online endeavours, particularly given the disparities that exist between disadvantaged and advantaged teachers in the South African context; and the belief that a bottoms-up approach to community formation allows space for a self-organizing system whose continual health and functioning is dependent upon local ownership and member identification. Having developed a mathematics-friendly online forum environment (ODEM) that allows teachers to include mathematical expressions in their posts, this study investigated the personal and situational tensions impacting on the use and value of this appropriate forum environment as a reflective tool in pursuit of CPD. Two groups of disadvantaged and advantaged mathematics teachers were separately provided with Personal Computers and home Internet access, thereby creating opportunities for reflection, communication with colleagues and the exchange of knowledge and ideas. Little evidence of community growth was found, while disadvantaged teachers faced more tensions than advantaged teachers in using the ODEM. Despite these differences, both groups' tensions pointed to their real (and thus forum) needs not being addressed. These forum needs are related to issues arising from their practice and the need for a channel of communication to a Subject Advisor that should actively manage these needs. A vertical relationship with the Subject Advisor is preferred over collegial interaction, over the needs to include expressions in their posts, or to reflect on their practice. Until teachers' needs are resolved, the ODEM is thus perceived to have potential value. The results furthermore informed a model that can be used by a Subject Advisor to determine teachers' tensions and needs in context, thereby ensuring appropriate online CPD strategies. / Mathematics, Science and Technology-Education / Ph.

This dissertation is studying e-learning – electronic form of education. At once it is analysing in details the advantages and disadvantages of this new form of education approach and is describing possibilities of some chosen e-learning systems and their basic structures. In the second part of this dissertation are said basic principles and possibilities of programming language Java in which language is designed it's own concept of system, that should make possible for users to manage and control the e-learning. In this part is described progress of communication between server and client, method of sending off the SQL (query) and receiving result too. In last part is viewed resulting application as a whole, is explained basic controlling, possibilities of administration and methods of entering data. Application itself is tested on local testing server.
