Teachers, pre-service teachers, and students understanding about the heat conduction

摘要

The purpose of this study is to analyze teachers, pre-service teachers, and students conceptual understandings related to heat conduction in macroscopic and sub-microscopic (verbal and visual). This description research involves 15 teachers, 33 pre-service teachers, and 39 students. Data were collected by using a conceptual understanding diagnostic test. The result shows that almost the participants know about the macroscopic level. However, most of them have a few understanding at the sub-microscopic level in verbally and no one of them can draw or represent the scientific conception about the sub-microscopic level. This study suggested that the sub-microscopic level of the science concepts must be learned and taught to students to make science more easy to understand and explained.
