Analysis of two-level representation about the heat convection between teachers and pre-service teachers

Abstract

Abstract The aims of this study are to analyse and compare the two-level representation (macroscopic and microscopic) about the heat convection concepts. This research involves 15 teachers and 33 pre-service teachers. Data gathered using the diagnostic test to explore the two-level representation through verbal and drawing tests. The result shows that at the macroscopic level many respondents have a correct answer but decreased in microscopic level even more at the visualization test, just a few respondents can give a correct visualization according to scientific conception. This research found that all participant is well known about the macroscopic level but they have a lack of 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.
