The purpose of this study was to assess the effectiveness of manipulatives on chemistry concepts. Manipulative activities were designed for four chemistry topics: Dimensional Analysis, Ionic Formulas, Molecular Shapes, and Stoichiometry. Seventy-five high school students were divided into a control or experimental group. The control group solved problems in small groups, while the experimental group used manipulatives to complete a guided activity. Students in the control group scored significantly higher on the posttest for the Dimensional Analysis and Ionic Formulas activities. There was no significant difference in the posttest scores for the Molecular Shapes and Stoichiometry posttest. While manipulatives can be an effective learning strategy to increase student achievement, it does not have the same effectiveness of peer collaboration in small groups.
