Summary
Teacher Code Switching Consistency and Precision in a Multilingual Mathematics Classroom
By Clemence Chikiwa & Marc Schäfer
This document is a study that investigated teacher code switching consistency and precision in multilingual secondary school mathematics classrooms in South Africa. Methods used for data collection were interviewing and observing five lessons of each of three mathematics teachers purposively selected from three township schools in the Eastern Cape Province.
This study drew from the work of Dowling(1998) to understand and analyse teachers’ language(isiXhosa) use in the classroom and the mathematical contents of the meanings communicated in the classroom activities. This study has used the four domains proposed by Dowling.
· * Esoteric - use of highly specialised, formal and abstract mathematical language and
content.
· *Public - referring to forms of expressions and content expressed in entirely everyday
terms.
· * Descriptive - uses specialised mathematical language imposed on non-mathematical
content.
· *Expressive - non-mathematical language to refer to mathematical content.
In the data analysis two dominant teacher code switching practises emerged. These were referred to as borrowing code switching (BCS) and transparent code switching (TCS).
· Borrowing Code-Switching (BCS): Teachers borrowed English words and added isiXhosa prefixes (e.g., "ku-Cosine," "ngu-ABC").
· Transparent Code-Switching (TCS): Teachers used clear isiXhosa equivalents (e.g., "krwela umgca" for "draw a line").
Teachers used BCS in more common than TCS and they used same word in different concept. For example, “Bala” was sometimes used for ‘calculate’, other times for ‘write’ and ‘count’.
This study recommend that mathematics teachers in multilingual classrooms need to be made aware of and encouraged to use available multilingual mathematics resources to aid their teaching and learning of mathematics. In addition to this, study concludes that best practices for code switching need to be established to promote transparent code switching that is precise, consistent and beneficial to increasing access to mathematical understanding in multilingual secondary school classes.
Stop 1
Consistency and precision in teacher language during the teaching of mathematics multilingual classes is crucial for enhancing access to mathematical concepts.(p.g.246)
This quote highlights the importance of code-switching in class, especially for a multilingual class. I can use this quote on our recent class discussion on how to define odd and even in different languages. We observed that, in the math language, odd and even have clear-cut definitions but in other languages they can have different meanings.
Similarly, in this study we see how the word "Bala" is used by teachers in different contexts with different meanings which confuse children. I can compare it to the word "Gunam" in Malayalam; when used in mathematics, it is multiplication, but generally refers to quality or virtue.
These inconsistencies in math vocabulary underscore the need for instructors to utilize concise and precise language to facilitate higher understanding for multilingual students.
Stop 2 Promoting conceptual understanding of mathematics intertwined with good language practices that support thinking are key to meaningful teaching of the subject.(p.g.252)
I stopped on this quote because it highlights something so important in teaching math—both good explanations and good language support are required for students to have full access to mathematical ideas. As a math teacher, I have seen students struggle when they are unable to grasp the meaning of a word or concept because of language limitations. For instance, when I am teaching fractions, there are some students who do not comprehend the terms "denominator" and "equivalent," and it makes problem-solving harder for them. But when I define these terms in a manner that relates to their daily vocabulary and lives, they grasp the concepts so much better. Putting it in simple terms, using examples from everyday life, and even alternating between languages when required assist students in thinking critically about math and not memorizing procedures. This is the reason why it is so critical to combine strong language practices with clear math instruction—by doing this, learning with meaning and building students' confidence in problem-solving becomes possible.
