  • the aida approach to Educational Software portability
    Journal of research on computing in education, 1995
    Co-Authors: Antonio Jose Mendes, Teresa Mendes
    Abstract:

    AbstractSeveral research and development projects have attempted to make Educational Software more portable. However, in most cases, packages are developed with a particular target group in mind. It is uncommon during a Software package’s development for the developers to introduce characteristics that facilitate the Software’s use in different settings and, eventually, in other countries. Educational Software portability is usually seen as a desirable characteristic, but in many cases no special development strategies, techniques, or tools are used to achieve that characteristic. Consequently, if someone wants to use the package in situations other than those for which it was intended, he or she must go through a difficult and expensive process of adaptation and translation. In this article, motivations for portability and some limiting factors of portability are analyzed. This article also describes the approach used in the AIDA authoring environment to facilitate translation and cultural adaptation.

  • Educational Software for stress analysis of non-idealized closed thin-walled sections
    Blue Eyes Intelligence Engineering and Sciences Publication, 2019
    Co-Authors: Mohamed Ali, Jaffar Syed, Mir Owais, Ali Ibrahim, Miah Mohammed Riyadh
    Abstract:

    Aerospace structures such as fuselage and wings are made of typical thin-walled closed sections and the detailed stress analysis of such closed thin-walled structures can be tedious and time consuming due to its statically indeterminate nature of the problem. In the present work, an Educational Software for the stress analysis of such non-idealized thin-walled closed sections has been developed that complements tradi-tional methods of teaching and learning. The Software developed is able to generate any given closed cross section which are subjected to bending, shear, and torsional loads and compute the resulting stresses on the cross section. Results from literature have been used to validate the results from the Software. The Software has been developed using Graphical User Interface (GUI) in MATLAB which makes the soft-ware very user friendly. The Software is expected to be an effective teaching and learning tool of courses on thin-walled structures and air-craft/automotive structures

  • Educational Software for stress analysis of idealized closed thin walled sections
    2018
    Co-Authors: Syed Mohamed Ali Jaffar, Nur Fadhila Hasna, Makame Burhani, Riyadh, Miah Mohammed
    Abstract:

    Aerospace structures are typical semi-monocoque structures that are made up of thin-walled closed section reinforced with stiffeners. Stress analysis of such closed thin-walled structures which are statically indeterminate is tedious and time consuming. An Educational Software which can aid students in stress analysis of such idealized thin-walled closed sections has been developed. The Software enables students to select different types of wing torsion box sections with stiffeners, which may be subjected to bending, shear or torsional loads and evaluate the resulting stresses on it. The Software allows the student to idealize a selected twin spar unsymmetrical wing section with multiple booms under multiple loads. Results from this Software have been validated against the results in the literature. The Software has been developed using MATLAB with graphical user interface (GUI) which is very user friendly. The Software is expected to be a very useful tool for effec-tive teaching learning of courses on thin-walled structures and automotive/aircraft structures

  • environmental detectives the development of an augmented reality platform for environmental simulations
    Educational Technology Research and Development, 2008
    Co-Authors: Eric Klopfer, Kurt Squire
    Abstract:

    The form factors of handheld computers make them increasingly popular among K-12 educators. Although some compelling examples of Educational Software for handhelds exist, we believe that the potential of this platform are just being discovered. This paper reviews innovative applications for mobile computing for both education and entertainment purposes, and then proposes a framework for approaching handheld applications we call “augmented reality Educational gaming.” We then describe our development process in creating a development platform for augmented reality games that draws from rapid prototyping, learner-centered Software, and contemporary game design methodologies. We provide a narrative case study of our development activities spread across five case studies with classrooms, and provide a design narrative explaining this development process and articulate an approach to designing Educational Software on emerging technology platforms. Pedagogical, design, and technical conclusions and implications are discussed.

  • an Educational Software suite for teaching design strategies for multistage axial flow compressors
    Journal of Turbomachinery-transactions of The Asme, 2012
    Co-Authors: Dario Bruna, Carlo Cravero, Mark G Turner, Ali Merchant
    Abstract:

    The T-AXI turbomachinery design system, an axisymmetric methodology recently developed with an Educational purpose, has shown great capabilities in the redesign of existing axial flow gas turbine components. Different turbomachines, single or multistage configurations, have been already reproduced with excellent overall performance results: examples are the NASA/GE E3 HP compressor and LP turbine. In this paper, the authors present a detailed analysis of the results of a “case-study” application of the code as a complementary tool to be used during a turbomachinery design course. The NASA/GE E3 HP compressor has been chosen as the test case. Starting from the data available in open literature the different steps of the redesign have been reported: from the flowpath generation through the thermodynamic properties distributions to the overall turbomachine performance analysis. Particular attention has been given to some critical aero design parameters. The links to some interesting and useful literature sources are reported. The free-vortex, the only vortex law included in the first version of the code has been used for a first EEE compressor redesign. Different design vortex methodologies have been implemented in the new release of the code and their effects on the angular momentum are reported. The corresponding geometries can also be interfaced to a mesh generator and then the turbomachinery configurations analyzed by a 3D Navier-Stokes solver. In this way the flow field can be carefully analyzed and the fluid-dynamic physics better understood. With the above Software structure the student has the opportunity to test the effects of different design strategies on the turbomachinery performance and to understand the need of a hierarchy of tools that give complete information for the multistage turbomachinery design. Finally, in the last section of the paper, the authors present how a project such as T-AXI, developed from their research activity in turbomachinery, numerical methods and CFD, can be included in the education tool CompEdu.
