    abstract     = {The presented study sought to determine what types of verbal interactions between a professor and four students of $3^\circ$ of ESO (14 years of age) are more effective for solving algebraic problems, working in a cooperative group. As a result of this analysis we identified six types of models of interaction that offer an improvement in learning opportunities to the members of the group. (Author's abstract)},
