Table 4 The overall coding process
Phase | Coding approach | Example | Coding result |
|---|---|---|---|
Step 1 | Item coding | Investigate the conditions of combustion (2022 CECCS, page 27) | - |
Step 2 | CCM analysis | Recognize that substance changes accompany the process of energy change, and the transformation of substances can be achieved through chemical reactions under certain conditions; Recognize quantitative correlations exist between substances in chemical reactions and develop an initial cognition of transformation (2022 CECCS, page 26) | NSC 1 |
Step 3 | Aligning each coding unit with the OECD competencies | Design and develop computer programs that can be used to investigate combustion conditions and quantitative relations of chemical relations (2022 CECCS, page 30) | Computational thinking/Coding/Programming |
Step 4 | Developing the heat map | Design and develop computer programs that can be used to investigate combustion conditions and quantitative relations of chemical relations (2022 CECCS, page 30) | Level 4 |
