Abstract

With the first issue of 2016, we published five articles dealing with different perspective of science education.
The first article from Brazil; Valéria Campos SANTOS and Dr Agnaldo ARROIO made a comprehensive literature review on the representational levels (macroscopic, microscopic, and symbolic) that involve models of thinking in chemistry. They reported the outcomes of theoretical and empirical studies about the representative levels in chemistry, science, and teacher education.
