<![CDATA[The learning model used can be improved through development in accordance with the desired achievement. because, it cannot be said with certainty that the use of a forced model will be able to make students interested in activities even though it does not rule out the possibility of learning interactions not going well. Based on the description of the data analysis table and the results of the standard deviation, it can be seen that the implementation of the problem based learning model in the specialization class of SMA Negeri 3 Jambi City is quite good. This is because, students already have sufficient knowledge related to the subject in question, although they are still constrained by the limited understanding of the theoretical language used from the subject matter received. In addition, students also tend to use the same case study to provide an example or an illustration related to the question asked. It can be concluded that the efficiency and effectiveness of developing learning models in accordance with learning conditions is able to direct students to the right flow of learning activities, although it is possible that learning success will be more optimal if learning time is not limited to school hours. With case study-based learning and the use of problemsolving-based models, it is expected to stimulate students' understanding of something new that can be found in their daily learning activities in class.The learning model used can be improved through development in accordance with the desired achievement. because, it cannot be said with certainty that the use of a forced model will be able to make students interested in activities even though it does not rule out the possibility of learning interactions not going well.
