How Keywords Impact Word-Problem Performance: When “More” Does Not Mean to Add

Although students are often taught to look for keywords when solving word problems, this strategy is erroneous. It is especially problematic when students solve inconsistent word problems that include a relational term, such as more but are not solved with the assumed operation (e.g., addition). In this study, we analyzed constructed equations on four word problems that included the word more for 112 Grade 3 students from a U.S. southwest school district. We compared students with and without mathematics difficulty and disaggregated based on dual-language status. Most students constructed accurate equations for the two consistent word problems, but fewer constructed accurate equations for the two inconsistent word problems. Students with mathematics difficulty, particularly those who were also dual-language learners, had the lowest rates of accurate equations on the inconsistent word problems. This analysis reinforces previous calls by researchers to avoid the ineffective keywords strategy.
