Representaciones de la generalización de una relación funcional y el vínculo con la mediación del entrevistador

The ability to generalize and represent the generalization exhibited by eight fourth-grade students was analyzed in this descriptive study, designed around a semi-structured interview involving a task based on the linear functional relationship y=x+2. The relation of the interviewer’s mediation on students’ representations of generalization was determined on the grounds of students’ interaction with her. Four forms to represent the generalization of a functional relationship were defined. The findings confirm the importance of mediation in helping students strengthen their ability to recognize, represent and generalize functional relationshipsThis work is part of the doctoral studies of the first author supported by Universidad de Costa Rica.
