[ Method ] Nosema bombycis was used to feed wild type and mutant drosophila, and the morphological observation of Nosema bombycis in drosophila body fluid was also analyzed by calcofluor white M2R fluorescent staining. [ Result] Nosema bombycis could infect drosophila, and the number of Nosema bombycis in the infected mutant drosophila was higher than that in wild type drosophila. [ Conclusion ] Nosema bombycis can infect drosophila, which provides primary reference for studies on the infectivity of Nosema bombycis to other hosts and also lays a foundation for further study on the infection mechanism of Nosema bombycis.展开更多

So we draw primary and secondary school teachers and normal students to arrive at the current status quo of educational technology ability and analyzes the strengths and weaknesses of the ability of its parts.

Led by that, the authors came up with the idea to examine the possibilities of the application of this principle within the courses of mathematics and music. This paper examines the relationship of correlation-integration-co-ordination, or linking-conjoining-harmonizing. The sample consists of the students at the fourth and fifth year of the Pedagogical Faculty in Sarajevo. The research topic is the correlation between mathematics and music. The research problem is the possibility to successfully realize a class in which mathematical and musical activities correlate. The aim of the research is to come up with some guidelines that would lead to a more successful application of the aforementioned correlation in practice. The conclusion is that we should work more on the possibilities of applying various forms of intercorrelation between subjects, to make the class content even more appropriate to the natural environment in which the child learns in a relaxed manner.展开更多

The social constructivist view of teacher education values teachers' agency in constructing and shaping personalized knowledge as a socially constructed experiential process in context. So, the researcher as an EFL educator in an Iranian teacher education university investi- gates the professional development of an EFL teacher during a three-year-time span both as a student and then as a teacher. Teacher journals, observation, and interview as three appropriate data gathering tools were used to obtain triangulated data. Student teacher professional change during the time span, multidimensionality of professional development, and discursively shaped personal beliefs and knowledge and their influence on teaching actions and practices were the emerged themes of data analysis based on Strauss (Qualitative analysis for social scientists. Cambridge University Press, Cambridge, 1998) constant comparative method, including three steps of open coding, axial coding, and selective coding. The findings of this research challenge the transmission nature of teacher education which assumes student teachers as the conduits, requiring to be filled with skills, input, and knowledge lectured by educators as authority figures.展开更多
