This research is quasi experimental research with a nonequivalent control group. The population in the research is class X SMA Negeri 1 Kampar Timur. The samples in the research was X MIPA 2 as an experimental class and class X MIPA 5 as a control class which was determined randomly. The experimental class was treated with the implementation of CORE learning model while the control class with a scientific approach. Data was collected using essay test instruments. The data obtained from test were analyzed descriptively and statistically by the test-t right side. The results of data analysis obtained tcount = 5,63 and ttable = 1,66 with α = 0,05, dk = 74. Tcount > ttable is 5,63 > 1,66 meaning that the implementation of CORE learning model can improve students concept understanding on the subject of atomic structure in the class X MIPA SMA Negeri 1 Kampar Timur. Criteria students concept understanding in the experimental class with an average N-gain of 0,80 while the average N-gain in the control class is 0,69.
