The way by which ancient Greek philosophers came to the concept of atom is presented. The concept of atom, a great creation of the human mind, gave a direct, modern-like explanation of the world, at times in which the huge amount of experimental and theoretical information of today was not available. This lack proved not an impossible obstacle for ancient Greek atomistic philosophers. The continuous regeneration, which makes Nature seem eternal, the physiology of nourishment, the orderly growth and decay of humans, animals and plants, the spreading of a sent, the evaporation and condensation of water, the wearing out of a pavement by the steps of passers-by etc., led philosophers to the concept of atoms. Similar experiences can be appealed to in teaching the concept today. Nevertheless, the concept of atom was not conceived in the same way in all ancient philosophical schools. The struggle to understand Nature, brought forth brilliant ideas and intuitions, which are directly connected to modern aspects of atomic theory, like the atomicity of time and the symmetries of the world of elementary particles. Teachers today can, with benefit to their students, retrace the ancient steps to atomic theory. 相似文献

In this paper we present the distance-learning (DL) environment of the Aristotle University of Thessaloniki, Greece. The technical
infrastructure is based on synchronous DL facilities. DL classrooms have been used successfully over the last decade. We present
a generic data model for DL service provision. Supplementary services have also been developed in order to provide support
for the DL service provision. The use cases of the DL service are described. The pedagogical issues regarding both students
and teachers have been investigated using statistical surveys. The findings are presented in this paper. Finally, the conclusion
and future work is discussed. 相似文献

This paper describes the use of a customized algorithm for the colorization of historical black and white photographs documenting earlier states of paintings. This study specifically focuses on Pablo Picasso's mid-century Mediterranean masterpiece La Joie de Vivre, 1946 (Musée Picasso, Antibes, France). The custom-designed algorithm allows computer-controlled spreading of color information on a digital image of black and white historical photographs to obtain accurate color renditions. Expert observation of the present state of the painting, coupled with stratigraphic information from cross sections allows the attribution of color information to selected pixels in the digitized images. The algorithm uses the localized color information and the grayscale intensities of the black and white historical photographs to formulate a set of equations for the missing color values of the remaining pixels. The computational resolution of such equations allows an accurate colorization that preserves brushwork and shading. This new method is proposed as a valuable alternative to the use of commercial software to apply flat areas of color, which is currently the most common practice for colorization efforts in the conservation community. Availability of such colorized images enhances the art-historical understanding of the works and might lead to better-informed treatment. 相似文献

This work investigates the effect a Web 2.0 learning environment may have in higher education in adding value to the students’ existing competencies. The major issues that this work examines are whether the incorporation of a Web 2.0 environment in higher education has an effect on the students’ performance and what are the significant factors that should be taken into account in the deployment of these technologies to achieve the maximum possible benefits and whether and how they correlate to each other. These factors are derived from the students’ views on the use of technology in a university course deployment and from the students’ personal opinions about a pilot course in a Web 2.0 learning environment. Although the results indicate no direct effect on the students’ performance, significant factors have been revealed via a thorough assessment, which has been performed in the context of a semester–long course, utilizing statistical process control techniques. The derived factors are namely: “Technology as an educational reinforcement”, “Technology as a tool to enhance comprehension” and “Enhancement of student interest and experience”, while in the second one “Completeness of the educational approach”, “Satisfaction from the educational approach” and “Course demands”. These factors can then form the basis for a feedback processes and a monitoring mechanism for a continuously updated educational process. 相似文献
