465 students, comprising students in Year 9 classes in Thailand, Year 10 students in Brunei Darussalam, and secondyear university students in the United States, attempted to solve the same quadratic equations. Most of the school students and many of the university students were confused about the concept of a variable and the meaning of 'solution to a quadratic equation'. Most of the students in the three subsamples acquired neither instrumental nor relational understanding of elementary quadratic equations. (orig.)
