SANCHEZ, Germán Hugo; QUINTERO, Teresa  and  LORENZO, María Gabriela. The caractheristics of teachers explanations in university classes of chemistry. Educ. quím [online]. 2021, vol.32, n.2, pp.109-119.  Epub Oct 11, 2021. ISSN 0187-893X.

The university classes usually have the characteristic of being master classes, nevertheless, the attributes that are proper to the explanations of specific chemistry topics remain to be described with the complexity inherent to teaching at this level. Consequently, analyzing the resources in the teachers' discourse is a key issue to review the university teaching of chemistry. A descriptive research with qualitative approach of the explanations in class of two Argentine university professors using elements of discourse analysis is presented. Diverse teaching resources, scientific language and representational levels of chemistry were considered. Both of the professors used a written material and varied discursive resources with high density of technical language in which the imaginary experiences were outstanding. The language was settled to the macroscopic level in permanent relation with the symbolic one. A subdivision of the macroscopic level is proposed. Finally, a reflection on the importance of the didactic training of university teachers is presented.

Keywords : University teaching; chemistry language; discourse analysis; macrochemistry; imaginary experiences.
