inclusion of people with special needs in the school environment is one of the current challenges of Brazilian education. Knowing how people in this environment perceive inclusion can contribute to the construction of solutions that make it complete. Thus, this work presents a study that investigated the conceptions that future teachers, undergraduates in science, have regarding the construction of scientific knowledge by congenitally blind people, in particular, regarding the understanding of the concept of light. The collected opinions were treated from a statistical point of view, through the Correspondence Analysis method. The results show there is no definitive consensus regarding the understanding and construction of the concept of light by congenitally blind individuals, showing the need to develop more adequate educational interventions in the teacher training process, with a view to the formation of educators capable of consolidating school inclusion.
Fluctuations in population density of planorbid hosts of S. mansoni are influenced by climatic factors. The knowledge about interference from changes in water temperature in these populations is an important aspect of the epidemiology of schistosomiasis. In this experiment, it is explored the influence of different temperatures on the development of Schistosoma mansoni in Biomphalaria glabrata melanic and albino variants. The results indicated an intrinsic relationship between temperature and development of the parasite in the intramollusc phase, independent of the pigmentation of the mantle of the molluscs. The higher the temperature, the shorter the period necessary for the development of the parasite was while the higher the mortality of infected mollusks. It is concluded that, in the presence of climate change, the increasement of temperature in cold and flooded regions may encourage the establishment of new foci of transmission of schistosomiasis by changing the geographic extent and extending the epidemiological transmission potential. In warm climates, higher temperatures, however, could compromise the transmission of the disease because of biological stress suffered by parasite and host. Under these conditions, it can result in the death of the parasite or a change in their ability to infect new host species of molluscs in new areas. Mantle pigmentation patterns in molluscs have not shown significant interference in the development of the parasite.
O estudo da Parasitologia embasa a construção de conhecimentos e propicia o reconhecimento de determinantes sociais e ambientais na transmissão das doenças parasitárias. Práticas de ensino mediadas por procedimentos significativos podem impactar positivamente o aprendizado dos graduandos. Objetivou-se com esta pesquisa compartilhar metodologias que favoreçam a aprendizagem através da utilização de práticas investigativas e reflexivas. Nos procedimentos metodológicos, além das aulas teóricas e práticas, foram desenvolvidas atividades que envolveram visitas a laboratórios de análises clínicas e curso de capacitação em ambiente virtual de aprendizagem. Os resultados demonstraram que as práticas docentes utilizadas atualmente se distanciam da abordagem contextualizada e problematizadora que a disciplina impõe. Esta pesquisa aponta a necessidade de (re)pensar o ensino de parasitologia sob o ponto de vista de uma aprendizagem bem-sucedida e oferece aos docentes pressupostos de uma educação contemporânea.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
