The photoelectric effect in the production and transformation of light is animportant phenomenon in quantum physics. The theory was initially presented by Albert Einstein and allows us to explain several technological applications in engineering. The use of computer simulations in the process, as they have already been proven to yield in science teaching, can provide excellent conceptual learning results, and that includes the teaching of the photoelectric effect. Ten simulations available on the internet were classified by criteria established based on bibliographic research developed within the framework of the historicity, concept, and context triad, and then four were selected and used in a classroom with engineering undergraduate sophomores. The Predict-Observe-Explain (P.O.E.) methodology was used to guide students in carrying out the experiments. The results of the analysis of the simulations and the elaboration of a laboratory instruction guide and experimental intervention, with the methodology, demonstrated the effectiveness of using computer simulations for the learning of scientific concepts in the context of engineering education.

The discipline of software engineering has been gaining increasing significance in computer science and engineering education. In this chapter, the goal is to describe a systematic approach toward integrating information technologies in software engineering education (SEE), both inside and outside the classroom. A methodology for integrating IT is proposed and explored in the context of SEE, particularly related to the Internet and the Web; in this context, SEE supports a heterogeneous combination of objectivism and constructivism, and aims to be feasibility sensitive. In doing so, the prospects and concerns of incorporating IT in SEE are presented. The potential of integrating IT in SEE is illustrated by examples.

Education Process

Engineering education process is heavily relying on the practical hands-on experimentation. However, todayâ??s education is involving more and more e-learning aspects and learners expect to get most of the content and activity available over the Internet. Practical experiments is not trivial to carry out over the Internet, but using novel ICT technologies and integrated solution, it is possible to offer real experimentation over the Internet. This paper describes and presents the remote practical experiment system in robotic and embedded system domain.

Gantry Cranes

Abstract Knowledge of vibrations and controls has increased significantly by utilizing emerging computer capabilities. Engineering education should embrace this technology through computer simulations that predict and display the dynamic response of interesting systems. For example, manipulating payloads with an overhead gantry crane can be challenging due to the oscillations induced by the crane motion. The problem gets increasingly difficult when the work environment is cluttered with obstacles. This paper describes a simple input shaping solution to the vibration problem and shows how this problem and concept were integrated into the curriculum of an undergraduate system dynamics and controls course at the Georgia Institute of Technology. Furthermore, an educational tool is used to gather data on how crane operators attempt to navigate around obstacles. The results show that input shaping reduces the likelihood of collisions between the payload and obstacles, while at the same time allowing operators to be more aggressive in selecting navigation paths.

Online Web

The power of the World Wide Web, it is commonly believed, lies in the vast information it makes available; "Content is king," the mantra runs. This image creates the conception of the Internet as most of us envision it: a vast, horizontal labyrinth of pages which connect almost arbitrarily to each other, creating a system believed to be "democratic" in which anyone can publish Web pages. I am proposing a new, vertical and hierarchical conception of the Web, observing the fact that almost everyone searching for information on the Web has to go through filter Web sites of some sort, such as search engines, to find it. The Albert Einstein Online Web site provides a paradigm for this re-conceptualization of the Web, based on a distinction between the wealth of information and that which organizes it and frames the viewers' conceptions of the information. This emphasis on organization implies that we need a new metaphor for the Internet; the hierarchical "Tree" would be more appropriate organizationally than a chaotic "Web." This metaphor needs to be changed because the current one implies an anarchic and random nature to the Web, and this implication may turn off potential Netizens, who can be scared off by such overwhelming anarchy and the difficulty of finding information.

Long Eighteenth Century

This Handbook traces the history of physics, bringing together chapters on major advances in the field from the seventeenth century to the present day. It is organized into four sections, following a broadly chronological structure. Part I explores the place of reason, mathematics, and experiment in the age of what we know as the scientific revolution of the seventeenth century. The contributions of Galileo, René Descartes, and Isaac Newton are central to this section, as is the multiplicity of paths to the common goal of understanding. Some of these paths reflected the turn to Thomas Kuhn’s category of ‘Baconian’ sciences — newer, more empirical investigations focused on heat, electricity, magnetism, optics, and chemistry. Part II looks at the ‘long’ eighteenth century — a period that covers developments relating to the physics of imponderable fluids, mechanics, electricity, and magnetism. Part III is broadly concerned with the nineteenth century and covers topics ranging from optics and thermal physics to thermodynamics, electromagnetism and field physics, electrodynamics, the evolution of the instrument-making industry between 1850 and 1930, and the applications of physics in medicine and metrology. Part IV takes us into the age of ‘modern physics’ and considers canonical landmarks such as the discovery of the photoelectric effect in 1887, Max Planck’s work on the quanta of radiation, Albert Einstein’s special theory of relativity of 1905, and the elaboration of the various facets of quantum physics between 1900 and 1930.

Way Of Thinking

When we look at todays Physics, we can only be impressed by an enormous amount of knowledge and a complete New World of technical applications that has never been in the world before. We now live in the century of the impressive victory of the new science and the new technology over the old-fashioned world and the old-fashioned way of thinking. Great changings in the way of thinking and the technological achievements are mostly characterized by an important scientific publication in a century that changes everything in that century. We can recognize the century of Isaac Newton who triggered in 1687 the large changings in thinking with his famous publication “Philisophiae Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy).We recognize the century of James Clerk Maxwell who triggered in 1865 the large changings in thinking with his famous publication “A Dynamical Theory of the Electromagnetic Field”.We recognize the century of Albert Einstein who triggered in 1905 the large changings in thinking with his famous theory of Special Relativity represented in his publication “On the Electrodynamics of Moving Bodies”. Manifesting a “New Theory” and a “New Way of Thinking” with important contributions of Hendrik Lorentz, Henri Poincaré and Hermann Minkowski.It is recognizable that with the suddenly changing in thinking in a new period, a new kind of mutual common sense and a general agreement by many scientists of the the new theory and the new way of thinking rises. The new theory becomes like a medieval town with a large high wall around it. The New Theory will be protected by common sense and mutual agreement. This new way of thinking settles down in the scientific society and become immovable. Other options disappear and simply do not exist anymore.

Resumo: Discutimos percepções sobre adolescência de um grupo de professores de ciências que frequentaram um curso de extensão. Para tanto, realizamos uma pesquisa qualitativa em educação com foco no cotidiano escolar que incluiu como instrumentos de pesquisa: material proveniente de videogravação, produções dos professores e anotações da pesquisadora. Na análise, usamos algumas ideias de Moscovici para representações sociais. Constatamos percepções pouco divergentes em relação aos estereótipos de adolescentes difundidos socialmente, ainda que tenham ocorridos avanços (como o reconhecimento de características dos adolescentes, das referências etc.) em direção aos conceitos científicos trabalhados no curso. Esperamos maior atenção sobre adolescência na formação de professores de ciências, posto que, possivelmente, essas percepções estão presentes na forma com que os professores exercem seu trabalho.Palavras-chave: Adolescência; Ensino de Ciências; Formação Continuada de Professores de Ciências Perceptions about adolescence by science teachersAbstract: We discussed perceptions about adolescence of a Science teachers group who attended an extension course. Although, we conducted a qualitative research in education with a focus on school routine, which included as research tools: video recording material, teachers productions and the researcher`s notes. In this analysis, we used some of Moscovici`s ideas for social representations. We found slightly divergent perceptions in relation to adolescents stereotypes that are socially disseminated. Even though advances have occurred (such as the recognition of adolescents characteristics, references and etc.) towards the scientific concepts worked on that course. We expect greater attention on adolescence in the training of Science teachers, since these perceptions are present in the way that teachers exercise their work.Keywords: Adolescence; Science Teaching; Continuing Education of Science Teachers.
