The purpose of this study is to acquire depiction of cognitive ability enhancement which the laboratory activities based inquiry implanted argumentation activities was conducted as a main process in the classroom activities. A quasi experiment method with non-equivalent control group pretest-post-test was carried out to implement this treatment. The participants of this study were students grade XI in one of public senior high schools in Indonesia. They were divided into two groups, experimental and control group, using purposive sampling. Experimental group was provided great opportunities to conduct laboratory activities based inquiry implanted argumentation activities while control group uses laboratory activities based inquiry. In order to recognize the cognitive ability of students, an instrument was developed in form of multiple choices. This study revealed that the mean difference of two groups was significantly different in which students' cognitive ability of experimental group was higher than this control group and was in medium criteria from normalized gain perspective. From this findings, implanting argumentation activities on inquiry lab played prominent role in constructing model and theory of knowledge for students in enhancing their cognitive abilities. © 2019 IOP Publishing Ltd.
