This work presents a partial analysis of the implementation of a didactic sequence aimed at undergraduate students of quantum chemistry. The sequence develops on some fundamental concepts to understand the behavior of the objects particles and waves in the doubleslit experiment. The analysis is based on the didactic transposition theory, proposed by Yves Chevallard, which allows reflection upon the scientific knowledge reorganized to be used in teaching contexts. Our interest in this study lays on the dynamics of transposition of knowledge-to-be-taught into knowledge-taught, particularly the importance of making concepts more comprehensible. Results showed that the communication of knowledge by the students is presented with interruptions, gaps and colloquial language. The analysis allowed the identification of needs and possibilities of learning, as well as a turn in the teacher practice, through a dynamic process of action and reflection.

The investigative practice as science teaching activity is recognized as an alternative to the learning improvement of science, becoming a perspective of work for teachers. This article arose from a study about the teachers formation process in the scope of investigative practices, conducted with trainee teachers of the Science Club of the Federal University of Pará - UFPA and students of basic education in public schools in Belém city, in order to discuss the theoretical-practical relationship in the planning of an investigative activity. In this process, some episodes indicate the necessity of such relationship, because in its absence the planning process shows itself to be questionable. Our analysis shows the importance of considering the theoretical context to conceive the planning and decisions regarding the conduction of the investigative practices, and oriented to a theoretical or practical goal.

A Mineração de Aspectos visa a identificar potenciais interesses transversais em código fonte de programa e a Refatoração para Aspectos visa a encapsulá-los em aspectos. A Mineração de Aspectos é um processo não-automático, pois o usuário precisa analisar e compreender os resultados gerados por técnicas/ferramentas e confirmar interesses transversais para refatorá-los em aspectos. Neste trabalho é proposta uma abordagem visual que lida com resultados gerados por duas técnicas de mineração de aspectos propostas na literatura. Por meio de múltiplas visões coordenadas, diferentes níveis de detalhe para explorar sistemas de software apóiam a análise e a compreensão de tais resultados para futura refatoração. O modelo de coordenação, implementado na ferramenta SoftVis4CA, é apresentado neste trabalho, juntamente com as visualizações e com os resultados preliminares obtidos.

The genus Mycteria (Ciconiidae) is composed of species with controversial phylogenetic hypotheses of relationships. This study sought to describe the cranial osteology of the four species included in the genus Mycteria, comparing with representative species from other genera of the family. The monophyly of Mycteria coud be hypothesized based on the following cranial characters: 1) medial process of the mandible medially oriented and 2) pseudo temporal tubercle developed when compared to other species Ciconiidae. Mycteria ibis and M. leucocephala are sister groups supported by: 1) deep temporal fossa, 2) reduced “T” tubercle and 3) expansion of the caudal fossa coanalis relative to other species of Ciconiidae. Among the species studied, the most basal was M. cinerea and the taxon formed by M. ibis and M. leucocephala is sister group of M. americana, sustained by the presence of total fusion of lacrimal and frontal bones, whereas in remaining species of Ciconiidae the suture between these bones is visible.
