The data included thirteen students’ (10 males and 3 females) pre and post modeling abilities test, and pre and post interviews. We designed and analyzed the interviews according to a coding scheme developed for an expert-novice study (Hsu et al., 2007). The results showed that students’ modeling abilities in designing a research to explore air quality have been improved, particularly in the reasoning process of anticipated conclusion and determine research variables of planning, and different performing students made a different improving pattern. The scaffolded modeling curriculums designed by the researchers shorten the gap between expert and novice in modeling air quality.
