Published Article / Mathematics teachers need an uncomplicated yet effective programme that they can use to type documents that contain mathematical symbols and notation. Many such programmes exist on the market, but are costly and in most cases, difficult to use. Microsoft Word's Equation Editor provides a solution to this problem in that it is easy to use and readily available in the Microsoft package. An investigation into how third-year education students respond to the presentation and use of this programme was made. The research was executed in the form of a case study, as only third-year mathematics students from the School of Teacher Education at the Central University of Technology, Free State, participated. It was found that these students grasped the concepts needed to use the Equation Editor quite easily, although the level of application by the academically stronger group of students was much higher than the level reached by the weaker academic group.

A hipótese do trabalho é a de que a participação do Brasil nas Exposições Universais fez parte dos esforços para recuperar e incrementar a atividade mineral no Brasil. Com três fases distintas, a representação do Brasil nestes eventos sofreu mudanças significativas nos primeiros certames ocorridos no Império; nas Exposições ocorridas na transição do Brasil Império para o período Republicano; e, por fim, nas Exposições ocorridas entre 1901 e 1911. Destacaremos os trabalhos desempenhados pelos comissários das seções de minerais que representaram o Brasil, inicialmente realizado por indivíduos ligados ao regime Imperial e que em seguida passou a ser feito por engenheiros de minas da Escola de Minas de Ouro Preto. Outro aspecto a ser abordado são os diferentes tipos de catálogos com informações sobre os minerais organizados para as Exposições Universais e o trabalho que as revistas especializadas em mineração como a Revista Industrial de Minas Geraes e a Brazilian Engineering and Mining Review realizaram na preparação e cobertura do Brasil para estes eventos. Por fim destacaremos as redes que envolviam instituições de ensino, museus comerciais, sociedades de geografia e as publicações sobre o Brasil que figuraram nas Exposições Universais elaboradas por brasileiros ou estrangeiros. / Abstract: This dissertation studies the sending of mineral samples to the World's Fair between the London Fair in 1862 and the Turim Fair in 1911. Our hypothesis is that the participation at the World's was part of the efforts to recuperate and develop the mining sector in Brazil. With three different phases, the Brazilian participation at the World's Fair passed by expressive changes since the first participations during the Empire Gouvernement; at the Fairs that happened during the transition of the Empire to Republic; and finally at the Fairs between 1901 and 1911. We will emphasize the services developed by the Brazilian commissaries of mining sections that represented the Brazil, realized at the beginning by individuals with relations with Imperial Gouvernement. At the next World's Fair this job was developed by mining engineers of the Mining School of Ouro Preto. Other aspect to be approached are the different types of catalogues with informations about the samples of minerals organized to the World's Fair and the services of mining periodicals like Revista Industrial de Minas Geraes and Brazilian Engineering and Mining Review since the Brazilian preparation for this events. Finally, we will emphasize the networks that involved faculties and universities, commercial museums, geographical societies, and the publications about the Brazil elaborated by Brazilians or foreigner that figured at the World's Fair. / Mestrado / Mestre em Ensino e Historia de Ciencias da Terra
