Results of Using Algebra Tiles as Meaningful Representations of Algebra Concepts.
Sharp, Janet M.
Mathematical meanings can be developed when individuals construct translations between algebra symbol systems and physical systems that represent one another. Previous research studies indicated (1) few high school students connect whole number manipulations to algebraic manipulations and (2) students who encounter algebraic ideas through manipulating physical models gain conceptual knowledge of algebra. Five high school algebra classes used algebra tiles to study operations with algebraic expressions. Results suggested no differences between groups who used or did not use manipulatives when tested with traditional chapter tests. Results of diary narrative data indicated that the majority of students stated that the tiles added a mental imagery that made learning "easier." They indicated that they found it easy to think about algebraic manipulations when they visualized the tiles. (Author)
