Emerging technologies in physics education

Three emerging technologies in physics education are evaluated from the interdisciplinary perspective of cognitive science and physics education research. The technologies - Physlet Physics, the Andes Intelligent Tutoring System (ITS), and Microcomputer-Based Laboratory (MBL) Tools - are assessed particularly in terms of their potential at promoting conceptual change, developing expert-like problem-solving skills, and achieving the goals of the traditional physics laboratory. Pedagogical methods to maximize the potential of each educational technology are suggested.Comment: Accepted for publication in the Journal of Science Education and Technology; 20 page

A Framework for Datatype Transformation

We study one dimension in program evolution, namely the evolution of the datatype declarations in a program. To this end, a suite of basic transformation operators is designed. We cover structure-preserving refactorings, but also structure-extending and -reducing adaptations. Both the object programs that are subject to datatype transformations, and the meta programs that encode datatype transformations are functional programs.Comment: Minor revision; now accepted at LDTA 200

Turning an Idea into a Valuable Teaching Resource and Research Output

This paper describes the journey of a teacher who became an author in Higher Education. The journey began with a simple idea about a fundamental resource book, designed to improve teaching in design and illustration classes with ever increasing numbers of novice fashion students, back in 1991. This resource was a taxonomy of fashion, designed to increase the awareness of garment shapes, context, proportion, terminology, construction, production and finish with a view to improving student knowledge, design and visual communication skills. The paper reflects upon the subsequent publications that built on the previous resource, as outputs of rigour, significance and integrity in shaping the author‘s approaches to teaching and research in fashion and other disciplines. It describes the development of the original idea and the subsequent acceptance of this for publication and illustrates how this one idea allowed for further opportunities for publications in a partnership with a global publisher. There are resource issues around gathering content for publications of rigour and originality and there have been challenges around communicating in the publications themselves due to technological and economical constraints. There are also practical resource issues around creating and designing the publications as well as the need for the development of personal skills when keeping up with changes in technology and the fashion industry. Each publication requires careful planning and needs to have unique reasons for being‘ that make it different to the competition. It describes the positive aspects of working with a colleague who brings similar skills and understanding, but a different handwriting and point of view to the publications. It looks at the impact of updating original editions and keeping the works contemporary. It also looks at personal and practical insights learned across almost 20 years of being an author with the same publisher

Situational awareness and safety

This paper considers the applicability of situation awareness concepts to safety in the control of complex systems. Much of the research to date has been conducted in aviation, which has obvious safety implications. It is argued that the concepts could be extended to other safety critical domains. The paper presents three theories of situational awareness: the three-level model, the interactive sub-systems approach, and the perceptual cycle. The difference between these theories is the extent to which they emphasise process or product as indicative of situational awareness. Some data from other studies are discussed to consider the negative effects of losing situational awareness, as this has serious safety implications. Finally, the application of situational awareness to system design, and training are presented

Simulation and Visualization of Thermal Metaphor in a Virtual Environment for Thermal Building Assessment

La référence est présente sur HAL mais est incomplète (il manque les co-auteurs et le fichier pdf).The current application of the design process through energy efficiency in virtual reality (VR) systems is limited mostly to building performance predictions, as the issue of the data formats and the workflow used for 3D modeling, thermal calculation and VR visualization. The importance of energy efficiency and integration of advances in building design and VR technology have lead this research to focus on thermal simulation results visualized in a virtual environment to optimize building design, particularly concerning heritage buildings. The emphasis is on the representation of thermal data of a room simulated in a virtual environment (VE) in order to improve the ways in which thermal analysis data are presented to the building stakeholder, with the aim of increasing accuracy and efficiency. The approach is to present more immersive thermal simulation and to project the calculation results in projective displays particularly in Immersion room (CAVE-like). The main idea concerning the experiment is to provide an instrument of visualization and interaction concerning the thermal conditions in a virtual building. Thus the user can immerge, interact, and perceive the impact of the modifications generated by the system, regarding the thermal simulation results. The research has demonstrated it is possible to improve the representation and interpretation of building performance data, particularly for thermal results using visualization techniques.Direktorat Riset dan Pengabdian Masyarakat (DRPM) Universitas Indonesia Research Grant No. 2191/H2.R12/HKP.05.00/201
