Previous issue date: 2011-05-20 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / This study aimed to identify and review of the conceptual differences presented by authors of books, focusing on the theme of electronic configuration. It shows the changing concepts of electronic configuration, its implications for the cognitive development of students and their relations with the contemporary world. We identified possible obstacles in books generated in the search for simplifications, situations of
different concepts of energy in the electron configuration for sublevels. For this analysis was carried out in several books, and some other general chemistry and inorganic chemistry without distinguishing between level of education, whether secondary or
higher. It was found that some books for school books corroborated with higher education, others do not. To check the consistency of what was discussed, it was a survey of 30 teachers, it was found divergent points of responses, particularly with respect to the energy sublevels and authorship of the diagram which facilitated the electron configuration. It was found that the total 22professores, ie, 73,33% answered
correctly on the energy sublevel more calcium (Ca) and 80%, ie, 24 teachers responded incorrectly on the iron. As for the authorship of the diagram used to facilitate the
electronic configuration, we obtained 93, 33% of teachers indicated that they followed a diagram, and this was called "Diagram of Linus Pauling," teacher 01, 3,33%, indicated
that the diagram was authored by Madelung and 01, 3,33%, did not respond to question. Was observed that it is necessary a more detailed assessment of ancient writings, as the search for simplifications and generalizations, not so plausible, lead to
errors and consequences negative for understanding the properties of many substances. It was found that quantum mechanics combined with spectroscopic data should be part of a more thorough analysis, especially when it extends situations atoms monoelectronicpolieletr?nicos to describe atoms, because factors such as effective nuclear charge and shielding factor must be taken into consideration, because interactions there is inside an atom, described by a set ofquantum numbers, sometimes not taken into account / Este trabalho teve como objetivo a identifica??o e coment?rio das diferen?as conceituais apresentadas por autores de livros, enfocando o tema configura??o eletr?nica. Essa an?lise mostra as mudan?as de conceitos sobre configura??o eletr?nica, suas implica??es no desenvolvimento cognitivo de alunos e as suas
rela??es com o mundo contempor?neo. Identificou-se em livros poss?veis entraves gerados na busca de simplifica??es, situa??es de diferentes conceitos de energia na configura??o eletr?nica por subn?veis. Para tanto foi realizada uma an?lise em v?rios
livros, sendo alguns de qu?mica geral e outros de qu?mica inorg?nica sem distin??o entre n?vel de ensino, se m?dio ou superior. Verificou-se que alguns livros de ensino m?dio corroboravam com livros de ensino superior, outros n?o. Para verificar a consist?ncia do que se estava analisado, fez-se uma pesquisa com 30 professores, em que foi encontrado pontos divergentes de respostas, com rela??o principalmente ?
energia de subn?veis e autoria do diagrama que facilitava a configura??o eletr?nica. Constatou-se que do total, 22 professores, ou seja, 73,33% responderam corretamente
sobre o subn?vel mais energ?tico do c?lcio (Ca) e 80%, ou seja, 24 professores responderam incorretamente sobre o ferro. J? quanto a autoria do diagrama usado para facilitar a configura??o eletr?nica, obteve-se93,33% de professores que indicaram
que seguiam um diagrama, e este era denominado de diagrama de Linus Pauling , 01 professor, 3,33%, indicou que o diagrama era de autoria de Madelung e 01, 3,33%, n?o respondeu a pergunta.Foi observado que ? necess?rio uma avalia??o mais minuciosa de escritos antigos, pois a busca de simplifica??es e generaliza??es, n?o t?o plaus?veis, levam a erros e consequ?ncias negativas para a compreens?o das propriedades de muitas subst?ncias. Verificou-se que a mec?nica qu?ntica aliada a dados espectrosc?picos deve fazer parte de uma an?lise mais minuciosa, principalmente quando se estende situa??es de ?tomos monoeletr?nicos para descrever ?tomos polieletr?nicos, pois fatores como carga nuclear efetiva e fator de blindagem devem ser levados em considera??o, devido a intera??es que h?
internamente num ?tomo, descrito por um conjunto de n?meros qu?nticos, ?s vezes n?o levados em considera??o

Mens en natuur - 'n bronnestudie oor die Bybelse en na-Bybelse perspektiewe (Afrikaans)Smit, Gerrit Daniel Stephanus 10 March 2004 (has links)
White (1967:1203-1207) places the blame for the current raping of our environment on the Christians’ interpretation of Genesis 1:28 (“God blessed them and said to them: ‘Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground”). White believes that the Christian interpretation of this verse teaches man to be arrogant toward nature and that God gives man the green light to exploit nature as man pleases. White has leveled serious accusations against the early Christians. This study interprets the Old Testament, New Testament and ancient theologians’ attitude towards creation and God. It deals with the accusations in accordance with the relevant Biblical and post-Biblical writers, to find the basis for the environmental crisis not in Christianity, but in animism. It is true that the ancient Christian writers were indeed more concerned about the hereafter than about the world as it is now. Yet, when one scrutinizes ancient writings, one soon realizes that in ancient biblical- and post-biblical time, earth stewardship has a profundity undreamed of by even the most speculative ecological philosophers. / Dissertation (MA (Greek))--University of Pretoria, 2005. / Ancient Languages / unrestricted
