This study included quasi-experimental research with the research design to be used, namely Pretest-Post Control-Group Design, which aims to determine the effect of inquiry learning models internalized Qur'anic verse verses on Islamic character and understanding the participants' chemical concepts students of class XI MIA MAN 2 Barru. The research subjects were the XI MIA 2 class as an experimental class which was taught by the model of internalized inquiry of the verses of the Qur'an and the XI MIA 1 class as a control class that was taught by the inquiry model without internalizing the verses of the Qur'an. Data were analyzed descriptively and inferentially. The results showed that; 1) The average value of the Islamic character of the experimental class aspects of gratitude, honesty, courtesy, and humility in the experimental class does not have very few criteria while in the control class has less and less criteria, 2) Percentage of understanding the concept of reaction rate in the class being taught with the inquiry model internalized the verses of the Qur'an is 78 in the good category while for the class taught by the inquiry model without internalizing the verses of the Qur'an the reaction rate is 69 in the sufficient category, 3) The test results The hypothesis for Islamic characters α = 0.05 obtained a value of tcount 6.067 > ttable 2.003 and significance (0.000 < 0.05) indicating that H0 was rejected and H1 was accepted, while testing the hypothesis for understanding the concept with t-test at a significant level, α = 0.05 obtained the value of tcount 2.117 > ttable 2.003 and significance (0.034 < 0.05), indicating H0 is rejected and H1 is accepted. From the results of this study it can be concluded that the use of inquiry learning models internalized by the verses of Al'qur'an influences Islamic character and understanding of students' concepts.

Problem based learning is a learning model that can improve students' attitudes. This article aims to review the results of the problem based learning model in improving the scientific attitudes of students in chemistry subjects. Problem based learning is a series of learning activities that emphasize the process of solving a problem faced scientifically. The method of writing in this article uses meta-analysis, by comparing information in the form of the pretest and pottest values in several similar articles. Based on the results of the analysis of several articles collected, the problem based learning model is able to improve scientific attitudes in chemistry subjects. The results of the comparison of the average increase of the 18 articles that were observed obtained a value of 18.27%. The paired sample test results obtained an average pretest of 56.03 while the average posttest of 74.29. Another result of the effect size test is that it is 1.390 in the strong category. The results of this article indicate that problem-based learning can effectively improve students' scientific attitudes in chemistry subjects.
