Data consisted of students' written work, videotapes of students working on various activities during class time, and clinical interviews conducted during the semester following the teaching experiment. Data was analyzed using the principles of qualitative data analysis along with a preliminary framework developed by the author. The framework was used for initial coding, and then patterns and relationships between the categories were evaluated.Sowder et al. found that teachers often could not distinguish between word problems that required an additive solution or a multiplicative solution. Conceptually, multiplicative solutions are more difficult because the aquot;unitaquot; can change.
