Appendix III: context-based modeling tests
Context-based modeling test I
Following the serious problems generated by global warming, many researchers start investigating the factors that may influence the raise of global temperature. The data shown in the table below are researchers’ results. Please answer the questions as follows.

Q1. Please draw a diagram (like curve, column, pie diagrams, and so on) to represent the relationship of the three compositions above (CO2, CH4 and Temp. of South Pole).
Q2. According to the diagram you drew in Q1, please explain the relationship of the three compositions above (CO2, CH4 and Temp. of South Pole).
Q3. According to the data shown in the table above, please provide other points of view, which need to be considered more or improved while dealing with this research.
Q4. According to the relationship of the three compositions (CO2, CH4 and Temp. of South Pole), please provide another similar pattern of relation from your life and explain it in detail.
Context-based modeling test II
Following the serious problems generated by global warming, many researchers have started investigating the factors that may influence the raise of global temperature. According to the current results, we know that global warming is caused by green house gases. The data shown in the table below are the different industry-level countries and the gases they produced in 2005. Please answer the questions as follows.

Q1. Please draw a diagram ( a curve, column, pie diagrams, and so on) to represent the relationship between the industry-level (high, middle and low) and four gases the three compositions (A, B, C and D).
Q2. According to the diagram you drew in Q1, please explain the relationship between the industry-level (high, middle and low) and four gases the three compositions (A, B, C and D).
Q3. According to the data shown in the table above, please provide other points of view that need to be considered or improved while dealing with this research.
Q4. According to the relationship between the industry-level (high, middle and low) and four gases the three compositions (A, B, C and D), please provide another similar pattern of the relation from your life and explain it in detail.
