Abstract
To reveal students' conceptual understanding of gas laws, this study focused on the understanding and application of scientific concepts in practical situations instead of the use of mathematical calculations in theoretical situations. One hundred and nineteen 11th grade students and 36 high school chemistry teachers participated in this study. We found that even very capable students possess alternative conceptions that are resistant to change. Moreover, analysis of the teachers' problem responses revealed that teachers and students held similar alternative conceptions of gases. These results indicated that not only chemistry teachers but also science educators should be encouraged to pay more attention to concept-based pedagogy.

Guy Ashkenazi , James S. Gordon , Jason D. HofsteinJournal of Chemical Education2008 85 (1), 72Previous research has documented a gap in students' understanding of gas behavior between the algorithmic–macroscopic level and the conceptual–microscopic level. A coherent understanding of both levels is needed to appreciate the difference in properties ...

Vicente TalanquerJournal of Chemical Education2006 83 (1), 127An equation of state expresses the characteristic relationship between state variables for a particular thermodynamic system. Knowledge of the equations of state for a given system can be used to derive all its thermodynamic properties. Despite their ...
