Cím:	Using particulate drawings to study 13-17 year olds' understanding of physical and chemical composition of matter as well as the state of matter / Zoltán Tóth, Edina Kiss

Megjegyzések:	Using Sanger's particulate drawings [J. Chem. Educ. 2000, 77, 762- 766.] a study was made of the understanding of the physical and chemical composition, and of the state, of matter, among Hungarian students aged 13-17. The evaluation of data at three levels (statistical analysis, content analysis of responses and structural analysis using knowledge-space theory) provided clearer and more reliable information about the conceptualization and cognitive organization of students' knowledge. The results show that Hungarian students have serious problems in distinguishing between homogeneous and heterogeneous mixtures, as well as the physical and chemical composition of matter. Among the classification strategies of unsuccessful students, both visual methods, including formal inspection of drawings, and conceptual methods, could be identified. According to the structural analysis (knowledge-space theory) only slight and temporary changes in the students' cognitive structure could be observed. A slight development in understanding of these basic concepts could be observed in grades 8 and 10 when Hungarian students study inorganic and organic chemistry.
