DE QUADROS, Ana Luiza et al. The knowledge of chemistry in secondary education: difficulties from the teachers' viewpoint. Educ. quím [online]. 2011, vol.22, n.3, pp.232-239. ISSN 0187-893X.

The present work sought to investigate the chemistry content that high school Brazilian teachers find difficult to work with in the classroom, the strategies, and the pedagogical resources they use to teach such content, and how students view this content. The interviews with 79 chemistry teachers from Minas Gerais State of high schools revealed an overemphasis on calculations to the detriment of content comprehension.
