A long-term shift to include students’ first language in the mathematics teaching practice: socialization events and learning opportunities

The notion of multilingual students’ first language has been advocated as a resource in mathematics learning for some time. However, few studies have investigated how implementing students’ L1 in the teaching practice impacts multilingual students’ mathematics learning opportunities. Based on a 9-month-long ethnographic study conducted in Iran, we investigate what a long-term shift from mathematics teaching in the language of instruction (Persian) to mathematics teaching that includes students’ first language (Turkish) may mean in terms of learning opportunities. In language positive classrooms, students’ socialization into mathematics and language includes using students’ first languages and paying explicit attention to different aspects of language use in mathematics. Among other things, socialization events provide possibilities to share explanations of mathematical thinking. The results of this study suggest that using students’ first languages may reinforce other language positive socialization events and provide mathematics learning opportunities during individual assignment activities. Furthermore, the results suggest that the conceived value of mathematics education in the local communities changed with the introduction of students’ L1 in the teaching practice. Consequently, this study indicates that using students’ first languages in mathematics classrooms may be a key issue in multilingual contexts.
