The research was a quasiâ€“experimental design (control group pretest-posttest design). The sample of this study included 74 of Mathayomsuksa 4 students from 2 classes in the first semester of 2020 academic year. They were selected to take part in the experiment as the control group and the experimental group through cluster random sampling. The duration of the research was 18 periods. The instruments employed in the study consisted of the lesson plans of active learning, the lesson plans of conventional method, mathematics learning achievement test, and mathematics problem solving abilities test. The data were statistically analyzed using mean, standard deviation, a <em>t</em>-test for independent samples, and a <em>t</em>-test for dependent samples. The findings of this study were as follows: 1) mathematics learning achievement and mathematics problem solving abilities on conic section of Mathayomsuksa 4 students after learning through active learning were higher than the conventional method statistically significant at a level of .01. 2<strong>) </strong>mathematics learning achievement and mathematics problem solving abilities on conic section of Mathayomsuksa 4 students after learning through active learning were higher than before learning statistically significant at a level of .01.</p>}, number={5}, journal={Journal of MCU Nakhondhat}, author={Auttayajirakul, Thanakrit and Sumirattana, Sunisa}, year={2022}, month={May}, pages={161â€“173} }
