The research stage begins with formulating research problems, the next stage is continued by analyzing research data in accordance with the inquiry learning model. In the process of data collection apply non-test techniques wheresearching for articles contained in electronic journals using the Google Scholar site. 25 scientific articles were obtained from various articles both national and international found based on the inquiry model. In accordance with the results of data analysis, it was obtained that in applying the inquiry learning model in the learning process, there was an increase in student academic achievement. This is evidenced by the lowest value data obtained with a percentage of 3.05% to the highest value with a percentage of 50.99% so that an average of 17.66% is obtained.
