SOCIOMATHEMATICAL NORMS, ARGUMENTATION, AND AUTONOMY IN MATHEMATICS
By Erna Yackel And Paul Cobb
In order to make sense of mathematics learning and teaching, the authors put forward a framework to interpret students’ learning from the perspective of sociomathematical norms. Sociomathematical norms, described by the authors, are unique to mathematics, in contrast with social norms which are general across all subject areas. “For example, the understanding that students are expected to explain their solutions and their ways of thinking is a social norm, whereas the understanding of what counts as an acceptable mathematical explanation is a sociomathematical norm” (p. 461). In this paper, the sociomathematical norms of mathematical difference and mathematical sophistication are established. The central idea of sociomathematical norms is that the normative aspect of mathematics discussion in classrooms is co-constructed by the teacher and students, which opposes the notion that mathematics learning is context-free. The author argues that what becomes mathematically normative in a classroom is shaped by the teaching goals, understanding of constraints, and negotiation among the classroom participants.
Further, the author illustrated how different sociomathematical norms regulate mathematical argumentation and provide extensive learning opportunities for both the students and the teacher. Whiles students consistently contribute to the classroom discussion by explaining their solutions, the teacher is offered opportunities in turn to develop notions of what is sophisticated and efficient for the children. The paper also discussed the link between sociomathematics norms and being autonomous learners. The author explained that autonomy takes place when students take responsibility to an extent beyond “being a student”. Such a transition requires awareness of sociomathematical aspects created by students and teachers. This is also noticed in many inquiry-based approach classes I have observed.
The authors argued that “initially, students' explanations may have a social rather than a mathematical basis.” (p. 467) While I had a very vague conception of the mentioned process, I experienced an enjoyable enlightenment reading this paragraph. One particular example was used for clarifying how the teacher and students interactively constitute what counts as an acceptable explanation and justification. In example 4, a student changed her answers and challenged the mathematical basis for explanations. The teacher explicitly acknowledged that “she changed her answers on the basis of her interpretation of the social situation rather than on mathematical reasoning, the teacher invents a scenario to clarify his expectations for this class.” (p. 468). I sense that this practice of the teacher was surprisingly effective and powerful since it created a concrete case that every student can comprehend and refer to.
Question:
The author distinguishes sociomathematical norms from social norms. How do you think norms in math classrooms differ from norms in other subjects?
