Procedimientos Rituales en la Resolución de Ejercicios en Contexto Algebraico en Estudiantes de Profesorado de Matemática

AbstractIn a research about symbol sense (ARCAVI, 1994, 2007) in Pre-Service Mathematics Teachers that were studying the last year to become Mathematics Teachers, we detected the presence of ritual procedures (VINNER, 2000) while solving algebraic tasks. During the analysis of the answers to the applied questionnaire, we observed that some of the students solved the same exercise using two different procedures. After obtaining the same answer by the second method as the one obtained by the first method, they were ready to give an answer. We will show some examples of this phenomenon and notice...
