The present study used the mixed item response theory (IRT) model to identify qualitatively distinct subgroups of sixth-grade students with respect to their performance on word problems on speed. A total of 345 Singaporean students and 361 Chinese students took a problem-solving test on speed. The mixed IRT analysis revealed two latent classes — the algebra proficient group and the algebra novice group. The algebra proficient group was more likely to use traditional algebraic and arithmetic strategies to solve the problems, whereas the algebra novice group was more likely to use model drawing, unitary, and guess-and-check strategies, in addition to …
