Dr. Erlina R. Ronda poses with her poster
 at ICME
Dr. Erlina R. Ronda presented a poster titled Algebraic-Thinking-Focused Approach for Teaching Subtraction of Integers at the 12th International Congress on Mathematical Education (ICME) held in Seoul, South Korea on 9-15 July 2012. In the poster, Dr. Ronda presented a research-in-progress report of her study of a teaching sequence developed by Grade 7 teachers of Sta. Lucia High School in Pasig. The study seeks to identify a typical learning trajectory for teaching addition and subtraction of integers and determine some design principles for tasks that will facilitate students’ understanding of, and computational fluency in, adding and subtracting negative numbers.
