Abstract
The purpose of this research study was to examine students’representations on Chemical Bonding at the 10th grade students issue of their post instructional inventory activities, which according to constructivist theory. Administer with a sample size of 34 secondary students at the 10th grade in Borabue Wittayakhan School, Borabue District in Maha Sarakham Province. Using the 14-Innovative Instructional Constructivist Theory Lesson Plans in 20 hours, mental representation test,and semi-structured interview. Statistics data analyzingwas descriptive statistics. The results of this research have found that: students’ responses of their understanding to their representations at the 5th level or reflective rhetorical use of representation in the properties and reactions of ionic compounds, formulations and nomenclatures of ionic compounds, and toward their energy with the formation of ionic compounds. It also found that the covalent bonding and bond length and energy, students’ responses of their abilities in representations at the 2nd level.
