In this research, the SOLO (Structure of the Observed Learning Outcome) Taxonomy presented by Australian scholars Biggs and Collis (1982) was adopted, and students studying the fifth and sixth grades in Taipei area were chosen as research targets.This study was primarily implemented with a quantitative analysis and supported by a qualitative analysis. In order to carry out the research, a questionnaire had been designed with criteria suggested by Jones et al.(2000), including "describing data","organizing and reducing data","representing data" and "analyzing and interpreting data." This questionnaire consisted of open-ended questions, and after analyzed with qualitative methods, the responses were classified and scored based on standards set in SOLO Taxonomy. Then the quantitative method "Partial Credit Analysis" from Rasch model was adopted in examining the reliability, validity and consistency of outcomes from the qualitative analysis.

In reaction-injection moldinga mixture of two or more reactive fluids is forced under high pressure into the mold cavity.Chemical reactions take place in the mold rapidly and the polymer solidifies.Various fibers such as glass,graphite,or boron may also be used to reinforce the materials.Structural foams are also produced by a similar methodusing an inert gasand resin mixture.The product consists of a rigid cellular(closed-cell)structure with a continuous solid skin as muchas 0.080 in.(2mm)in thickness.There are several methods for forming structural foams with density reductions as much as 40% from the solid structure.Because stiffness is proportional to the third power of the thickness of a part,for the same weight of material used,cellular structures are stiffer than solid plastics or metals.
