MAGINA, Sandra; CAZORLA, Irene; GITIRANA, Verônica  and  GUIMARAES, Gilda. Concepções e concepções alternativas de média: um estudo comparativo entre professores e alunos do ensino fundamental. Educ. Rev. [online]. 2010, n.numeroespecial02, pp.59-71. ISSN 0104-4060.

The present study aims to analyze students and teachers conceptions and misconceptions of average. A paper and pencil test, comprised of three questions, was designed. 287 Brazilian students and teachers undertook the test. They were: 54 pupils from 4th grade, 47 from 5th grade, 61 students beginning undergraduation on Pedagogy, 82 students finishing their undergraduation on Pedagogy and 43 elementary school teachers. The test was undertaken in a collective way. Excepting to the teachers group, all the groups tend to confuse average to addition of the values, or to the maximum value. The result points that, in spite of an evolution on the understanding of the concept of average according to the educational level of the groups, some misconceptions are found within the teachers’ group.
