This study is a development research, which aims at developing learning tools using Schoology to enhance learning motivation of students on chemical equilibrium subject which is valid, practical and effective to be applied. The development model used in this study referred to Hannafin & Peck’s development model which consisted of need assessment, design, development and implementation. The learning tools using Schoology which had been developed; then, it was validated by two experts. After the validation, the tryout of the learning tools using Schoology was conducted at SMA Negeri 1 Polewali Mandar in grade XI MIPA 4 with the total of 30 students. The result of the study reveals that the learning tools using Schoology development which had been validated shows the mean score of 3.40 which is in valid criteria. The learning tools using Schoology is stated as practical and effective because the practical test which related to: (1) the implementation of learning tools using Schoology is in M = 1.85 in the category of (1.5 ≤ M ≤ 2.0) meaning that the aspect and criteria observed in the implementation of learning tools using Schoology is in entirely implemented category, (2) teachers gave a very positive response on the learning tools using Schoology by 100%, and (3) the students gave a very positive response on the learning tools using Schoology by 85.49%. The learning tools has met effective criteria with the following result: (1) the enhancement of learning motivation of students is from 72.89% to 84.28%, (2) the learning activity of students with the mean score 91.33 is in very active category, and (3) the learning result of students has met effective criteria (≥80%) with the mean percentage of 85.60% which overall is stated as it has met the minimal completeness criteria of the subject.

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.
