Resumen
The aim of this study is to investigate the similarities and differences regarding the
methodological approach found in USA and Brazilian textbooks dealing with
logarithms. For this purpose we researched on twenty-two textbooks of Mathematics
that addressed such content. At first we carried out a historical overview about
logarithms since its invention by Napier in 1614 through his work Mirifici
Logarithmorum Canonis Descriptio, also considering the collaboration by other great
mathematicians like Bürgi and Briggs. After, we carried on an analysis of textbooks
research by means of a bibliographical search, qualitative and descriptive according to
Gil (2002), and on a second moment, the principles of Bardin content analysis (2011).
As a result of the analysis we concluded that USA books are more well founded and
focused on learning, especially from 1980 onward, having a much larger number of
examples and exercise, by direct application, settings, properties, or contextualized in
some way. However, the Brazilian books are geared toward classical education without
many examples, being quite direct.
