Abstract
The aims of this study are to analyze and compare the two-level representation (macroscopic and microscopic) about the heat convection. This research involves 15 teachers, 33 pre-service teachers, and 39 elementary students. Data gathered using the diagnostic test to explore the two-level representation through verbal and drawing tests. The result shows that in macroscopic and microscopic level teacher and pre-service teachers have a better understanding than a student. At the macroscopic level, many respondents have a correct answer but decreased in microscopic level even more at the drawings test, just a few respondents can give a correct drawing. This research found that all participant is well known about the macroscopic level but they have a lack knowledge about the microscopic level. This research suggests that to make students more understand about science the learning must give multiple representations to make they understand about scientific phenomena.
