Abstract: The main purpose of this research was to investigate eleventh grade students’ conceptual understanding in chemical equilibrium from learning by using inquiry incorporated with predict-observe-explain learning technique for 10 hours. The data collecting tools consisted of 2-tier diagnostic conceptual test and mental model test. The dependent samples t-test analysis of students’ conceptual test scores indicated that the post-conceptual test score (mean 19.32, S.D. 6.09) was significantly higher than the pre-conceptual test score (mean 8.06, S.D. 3.21) at the 95% confidence level. After the implementation, the total percentages of students in no- and mis-conceptual understanding (NU+MU) categories decreased by 29.01, while the total percentage of students in the sound and partial conceptual understanding (SU+PU) categories increased by 32.72. The mental model analysis revealed that the total percentage of students’ mental model in no- and mis-conceptual understanding (NU+MU) categories was 15.55 and the total percentage of students in the sound and partial conceptual understanding (SU+PU) categories was 68.89. This verified that this implementation was effective to develop students’ conceptual understanding of chemical equilibrium.
