Abstract
This study aimed to: (a) understand practicing teachers’ knowledge of model functions and modeling processes, (b) compare the similarities and differences between the knowledge of science and non-science major teachers, and (c) explore the possible reasons for the similarities and differences between the knowledge of these 2 groups. A 4-point Likert scale questionnaire was developed and used to measure the knowledge of 187 practicing elementary school teachers (94 science majors and 93 non-science majors) on model functions and modeling processes. The author selected 10 target teachers to conduct think-aloud interview and to explore their ranking. One month after completing the questionnaire, 28 volunteer teachers were selected for a follow-up interview to better understand the reasons for their responses. The results show that these teachers tend to agree or strongly agree with the items about model functions and modeling processes. The only significant difference between science and non-science majors was for the item “generating new ideas.” Qualitative analyses of the follow-up interviews and think-aloud results showed that teacher education and professional development did not focus on understanding and using models. Science-major teachers tended to formulate their responses with reference to specific models, while the non-science major teachers’ responses contained acquiescence bias. Finally, implications for science education are discussed.

Items of the Four-Point Likert Scale Questionnaire of Model Functions and Modeling Processes
Please answer the following questions about a scientific model from your viewpoint:
Item | Strongly agree | Agree | Disagree | Strongly disagree |
|---|---|---|---|---|
1. I think model functions can be for describing specific objects or phenomena. | ||||
2. I think model functions can offer one picture of vision and show specific objects and phenomena. | ||||
3. I think model functions can be used for explaining the relations of specific objects or phenomena. | ||||
4. I think model functions can offer a standard reference for me to follow. | ||||
5. I think model functions can be used for reasoning. | ||||
6. I think model functions can be used for solving problems. | ||||
7. I think model functions can be used for communicating ideas. | ||||
8. I think model functions can be used for predicting the future development of objects or phenomena. | ||||
9. I think model functions can be used for simulating or executing the actual operation of phenomena. | ||||
10. I think model functions can be used for generating new ideas. | ||||
11. For the same object or phenomenon, I think I will select different models for different purposes. | ||||
12. I think that building a model should include the components and structure of objects or phenomena. | ||||
13. I think we could use different methods to examine models. However, I must revise models when descriptions or explanations produce inconsistent results. | ||||
14. I think I can refer to a generally accepted model as the standard to help me judge whether other types of problem solutions are appropriate. | ||||
15. I think I can look for inspiration for solving problems from the existing models when facing new problem situations. | ||||
16. I think a model can be used for solving a problem effectively, but it still has limitations in its applications and needs further consideration. |
