This classroom research project used modeling activities to determine the effects on student achievement, engagement, and higher-order thinking skills. Test scores and student engagement observation data from the treatment and non-treatment portions of the study were compared. A rubric was also used to evaluate student-created models. The research project did not show significant improvement in test scores, but student engagement did increase. Students also showed improvement in higher-order thinking in the treatment phase of this study.enChemistry--Study and teachingHigh school studentsModelingThought and thinkingMotivation in educationNext Generation Science Standards (Education)Professional PaperCopyright 2019 by Deborah Sue Price
