The problem in this study is related to the low ability of students' mathematical connections. Therefore, the purpose of this study was to determine the effect of the Jigsaw Cooperative learning model on the mathematical connection abilities of class VIII students in the even semester of SMP Negeri 3 Bandar Lampung in the 2020/2021 school year. This study uses experimental methods, as well as data analysis using parametric statistical formulas. The population in this study were all students of class VIII SMP Negeri 3 Bandar Lampung which consisted of 10 classes with a total of 314 students, while the sample was taken 2 classes, namely class VIII B as the experimental class which amounted to 35, and class VIII A as the control class which amounted to 33 The sample was taken using the Cluster Random Sampling technique. To determine the students' mathematical connection ability, it was measured using a test in the form of an essay as many as 5 questions which had been tested for validity and reliability. Hypothesis testing in this study used the t-test formula. From the results of hypothesis testing using the t-test statistical formula, the value of t hit = 2.47 is obtained. From the t distribution table at a significant level of 5%, it is known that t daf = ????(1−????)= 1.67, which means that t hit > t daf is 2.47 > 1.67, so it can be concluded that there is an effect of the Jigsaw learning model on the mathematical connection abilities of class VIII students in the even semester of SMP Negeri 3 Bandar Lampung in the 2020/2021 school year. This situation can also be seen from the average value of students' mathematical connection abilities where theexperimental class has an average value of 77.37 and the control class has an average value of 68.67.

The problem in this study is the low ability of students' mathematical problemsolving in learning mathematics. The purpose of this study was to determine the effectof applying the contextual teaching and learning approach to the mathematicalproblem solving abilities of Grade VIII students in odd semesters of SMP Negeri 34Bandar Lampung in the 2022/2023 academic year. This study used an experimentalmethod with the population in this study, namely all students of class VIII Odd SemesterSMP Negeri 34 Bandar Lampung, while two classes were taken as samples, namelyclass VIII B which used a contextual teaching and learning approach, and class VIII Awhich used a conventional approach. Samples were taken using the Cluster RandomSampling technique. To find out students' mathematical problem solving abilities, a testwas carried out in the form of an essay of five questions which had previously beentested for validity and reliability. Hypothesis testing in this study uses the t-hit formula.From the results of testing the hypothesis using the t-hit statistical formula, the valueof t hit = 2.60 is obtained. From the t distribution table at a significant level of 5% it isknown that t daf = 1.67, then t hit > t daf , which means that the average mathematicalproblem solving ability of students using the contextual teaching and learningapproach is higher than the average mathematical problem solving ability of studentsusing the conventional.
