Summary: 
Mathematical modeling in teaching is getting more and more attention. That is reflected in the new General Education program, which considers mathematical modeling one of the core mathematical competencies. Many researchers around the world have given their views on mathematical modeling and the mathematical modeling process. Our research aims to build a teaching process to resolve practical problems on exponential and logarithmic inequalities to develop mathematical modeling competence for students in Vietnam. By the method of theoretical research, survey, and descriptive statistics method, the results showed that mathematical modeling of practical problems under exponential and logarithmic inequalities has a positive impact on students. By surveying 82 students, it is found that students showed more interest in class and actively participated in lessons. Students would rather solve problems on their own than constantly ask for help from the teacher. Students, through practical activities, showed remarkable progress. Students know how to come up with solutions to a real-world problem involving exponential and logarithmic inequalities. These facts demonstrate the importance of teaching modeling of actual issues on exponential and logarithmic inequalities for students.
