Frequency, significance and clarity : factors supporting the learning of mathematical vocabulary in bilingual classrooms

Abstract

A crucial part of mathematics education is the teaching and learning of mathematical language, which includes subject-specific vocabulary. In a study carried out in two Maltese primary classrooms wherein mathematics was taught through the students’ L2 (English), and a teacher-directed ‘whole-class’ approach was used, it was noted that three conditions for vocabulary use – frequency, significance and clarity - appeared to be necessary for teaching new topic-related vocabulary. In this paper, I explain these conditions as they emerged from my empirical data and then conjecture on their relevance to other classrooms wherein both Maltese and English might be used, since code-switching is the most common approach used in Malta for teaching mathematics. I suggest that while frequency of use of words is likely to depend on the teaching methods employed, code-switching might further promote the significance of mathematical words; furthermore, I suggest that using both languages might actually support clarity of the meaning of the topic-related words. Finally, if we wish to make a shift away from traditional whole-class teaching, we will need to equip students with the language necessary to engage differently with mathematics, irrespective of the medium of instruction used.
