We will focus on a group of Portuguese prospective mathematics teachers’ perspectives about some of alfamat’ s characteristics as well as on its usage and consequent implications for their learning. Some special features stand out: interaction as a mediator of students’ reflection and sharing of ideas about subject matters; interaction as a catalyst of students’ performance; interaction as a means for rethinking and reformulating individual ideas based upon others’ ideas and experiences.engLearning environmentDiscussion forumsStudentsInteractionsconference paper
