Pretreatment and posttest measurement models. Panel one shows the base pretreatment measurement model, which incorporated each of the six dimensions of pretreatment ability measured in September and October: language ability, attentive behavior, nonverbal reasoning, calculations skill, word-problem skill, and DA. Panel 2 shows the two dimensions of posttreatment word-problem outcome measured in March: near-transfer word problems (Algorithmic Word Problems and Complex Word Problems) and far-transfer word problems (Real-World Problem Solving, the Iowa, and WJ Applied Problems).
