ORTIGAO, Maria Isabel Ramalho. An analysis of the practices of mathematics teachers in basic education. Est. Aval. Educ. [online]. 2011, vol.22, n.48, pp.29-52. ISSN 0103-6831.

The study aims to describe teaching practices in Mathematics based on the information obtained by applying a self-administered questionnaire. This was submitted to a sample of 169 Mathematics teachers who teach at the elementary level in public and private schools in the city of Rio de Janeiro. In order to obtain a characterization of the schools where these teachers work, a second questionnaire was submitted to a sample of students, producing an average socio-economic and cultural profile of the students at these schools. Likert scales were constructed and validated to entice teachers to take a stand in relation to didactic approaches implemented, the organization of classes and procedures used to formally assess the students. These were asked to provide information on property ownership, study habits, family education. The quantitative analysis was performed using the theory of nonparametric item response. The measurement model supported in the responses to items about educational practices in Mathematics identified five scales with good statistical properties.
