| Dorothy Gabel pioneered the use of particulate level explanations in high school chemistry with her contributions to the textbook “Chemistry: The Study of Matter” in 1989. This work using particulate level explanations in the teaching of chemistry was continued with the development of the Symbolic-Application- Particulate (SAP) Test to evaluate students' understanding of matter on all three levels. The use of particulate level teaching and the subsequent evaluation of student understanding were combined in a study of student achievement at ten different high schools comparing the effect of teaching on both a particulate and nonparticulate level. Although no statistically significant effect for the teaching on a particulate level was found when the treatment groups were compared, a significant gender effect was found showing that particulate level teaching significantly improved the achievement of high school female students. This presentation will present the results of that study and describe the use of the SAP test to determine students' understanding of chemistry topics on three levels of matter. |
