The article is devoted to the method of studying isoprocesses in gases in physics classes using the example of studying the Boyle-Marriott law. It compares two approaches: the traditional one, which uses analog instruments, and the innovative one, which uses digital sensors and computer programs. Traditional tools are easy to use, visual, develop students' practical skills, at the same time, they have low measurement accuracy, time-consuming processing of results, limited possibilities for visualization and data analysis. To study the isothermal process, a glass tube 600 mm long and 8-10 mm in diameter, welded at one end, a cylindrical vessel 600 mm long and 40-50 mm in diameter, an aneroid barometer, and a ruler are used. We measure the length of the tube (l1) and atmospheric pressure (p1). Then we immerse the tube in a vessel with water, measure the length of the air column (l2) and the difference in water levels (h). We calculate the pressure p2, p1l1, p2l2, ε1, ε2, Δ1, Δ2. We compare p1l1 and p2l2. Innovative tools are considered on the example of LabQuest Vernier and have high measurement accuracy, speed and ease of processing results, extensive opportunities for visualization and data analysis, modeling and experimentation opportunities, but have a higher cost, complexity of use at the initial stage, less visibility , may require additional knowledge and skills. The technique consists in using a pressure sensor for LabQuest, setting the data collection mode. Set the syringe plunger to 10 ml, connect the syringe to the sensor. Collect pressure and volume data by varying the volume of the syringe by 5; 10; 12.5; 15; 17.5 and 20 ml. Draw a graph of the dependence of pressure on volume. Determine the mathematical relationship between pressure and volume using curve fitting. As a result, an inverse relationship between pressure and gas volume is established in the form of a regression equation: y = AxB, where A is the constant of proportionality, B is the exponent. The authors propose a promising approach that combines components of traditional and innovative research settings. For example, Vernier pressure and temperature sensors can be used with traditional gas law equipment. This will make it possible to increase the accuracy of measurements, make the research process faster and more efficient, preserve the visibility and practical component of the research, and expand the possibilities for data visualization and analysis. Both approaches to the study of isoprocesses in gases have their pros and cons. The combination of traditional an
