            The results showed that: 1. Academic achievement in literature, Phra Aphai Mani, namely, “Phra Aphai Mani Ni Nang Phisuea”  Matthayomsuksa 3 students’ achievements in their literature class before and after problem-Based learning  found that the post-test scores were significantly higher than the pre-test scores at a level of .05, with the pre test scores being 27.29 percent and the post test scores being 81.67 percent, with a progress score of 54.38 percent. This indicates that Matthayomsuksa 3 students’ have the ability to learn by learning management using problem-based teaching methods. (Problem-Based Learning : PBL) after learning, which is 54.38 percent higher than before learning. 2. Opinions of Mathayomsuksa 3 students regarding learning management using problem-based teaching methods. (Problem-Based Learning: PBL) Overall, the mean was at the very agree level ( = 3.73, S.D.=0.56) and when considering each aspect, it was found that the mean was at the very agree level in every aspect.
