GONZATO, Margherita; DIAZ GODINO, Juan  y  NETO, Teresa. Assessment of learning and mathematical knowledge on viewing three dimensional objects. Educ. mat [online]. 2011, vol.23, n.3, pp.5-37. ISSN 1665-5826.

In this paper we consider the problem of assessing didactic and mathematic pre-service teachers' knowledge about visualization of three dimensional objects and we describe the development of a test for this purpose. From the analysis of researches on the subject, the contents found in textbooks and the objectives described in the curricular design, we describe the selection of five kinds of task. The structure of each item and the formulation of the instructions take into account some specific aspects of the different components of the didactics and mathematics teachers' knowledge that we want to measure. The analysis both of a test' item and a pre-service teacher's answers brings clarity to the different evaluated kinds of knowledge and show the usefulness of the test to guide the teachers' training in the field of spatial visualization.

Palabras llave : didactics and mathematics teachers' knowledge; geometry; spatial visualization; assessment; pre-service teachers.
