This study investigated the development of students' abilities to see connections between algebraic equations and life-situated relationships during an extended problem solving experience. The design problem required students to analyze some aspect of their socio-physical environment for cause and effect and to generate a dynamic model using the MicroWorlds Project Builder programming environment. Eighth grade students (n=49) participated as subjects in a posttest only, intervention/control group design. Students randomly placed in the instructional intervention group participated in a simulation building experience over nine class periods. The posttest measured students' abilities to relate algebraic equations to real life situations and model real life situations in terms of algebraic equations. Control group and intervention group student performances were then compared for differences in representation translation abilities. Results suggest that the simulation building activities developed learners' abilities to make connections between algebraic expressions and life-situated relationships. Appendices contain classroom exams and computer commands. (Author/MKR)
