As Table 1 shows, for the MR group, the source included two Mathematical word problems, solution Reminding and line graphs of solutions. For the SR group, the source included two Science problems, solution Reminding and line graphs of solutions. Children can apply the basic ratio knowledge learned from source to solve target problems. Meanwhile, after learning the source problems subjects were requested to identify the fields of source problems that they have learned before and then induce schema from source materials. The inferential thinking question is a multiple-choice test.
Subjects have to generalize a correct statement that was induced from target problems solving.
In the NR group, a story of magic leaves was given as a source material. Subjects were divided into four groups according to what kind of source materials they learned. Four kinds of source materials given to children were MR, SR, NR, as well as Science problems and Pictures Reminding, and then they were requested to solve target problems which included two science problems. The SPR group was provided with pictures that represented the science problems contents, solution reminding and line graphs of solutions. Subjects were also requested to identify the fields of source problems they have learned before and then induce schema from source materials in the MR, SR, and SPR groups.
