The role of the Singapore bar model in reducing students' errors on algebra word problems

This study investigated the role of the bar model method, a significant aspect of the Singapore mathematics curriculum, in the remediation of seventh-grade students' errors on algebra word problems. To accomplish this purpose, we first assessed students' errors on a written test involving algebra problems and identified ten students based on the errors they demonstrated. These students were then offered instruction on how to use the bar model method. Following the instruction, we did clinical interviews and observed that the Singapore bar model method helped students understand the problem and transform words into mathematical expressions. Hence, the bar model served as an assistive tool for the remediation of students' errors in algebra word problems by facilitating students' comprehension and transformation
