Abstract: | This study explored the problem-solving schemas developed by 7th-grade pre-algebra students as they participated in a teaching
experiment that was designed to help students develop effective schemas for solving algebraic problem situations involving
contexts of (1) growth and change and (2) size and shape. This article describes the qualities and types of schemas that students
developed through examples of problems used to develop schemas, examples of students' reasoning and writing, and excerpts
from student interviews. Findings from the study indicated that there is a link between the type of generalizations students
construct and the schemas they are forming. By using these schemas students recognize, extend, and generalize patterns and
quantitative relationships both verbally and symbolically.
