Mathematical Meanings of Korean and USA Mathematics Teachers for Mathematical Ideas They Teach


"There are many studies of teachers' mathematical knowledge for teaching mathematics, mostly at pre-high school levels. In my presentation I will give an overview of the MMTsm and comparative results from the USA and Korea. In this brief summary I discuss one item as an example of items on the MMTsm, and present comparative results on it. The item focuses on one aspect of teachers' meanings for function notation--the use of letters to represent the function's argument. Additional items in the MMTsm on function notation suggest that Korean teachers' meanings for function notation are more nuanced than this one item reveals. My conference presentation will address general results and comparisons, as well as comparisons between Korean high school and middle school teachers."
