This study aims to determine the effect of using student worksheet (LKPD) based on the Problem Based Learning model on the mathematical problem solving abilities of students of class VIII SMP Negeri 2 Pangean. This type of research was a quasi-experimental study with a pretest – posttest control group design. The population was all students of SMP Negeri 2 Pangean Indonesia in the 2019/2020 school year. Sampling method was using random sampling technique. Based on the results of data analysis, the posttest mean score in the experimental class was 85.45 and the average value in the control class was 54.5, meaning that the average value of the experimental class was higher than the control class. The two-mean difference test using the t test was significant (2-tailed) 0.000 <α = 0.05, which means that the posttest score of students 'mathematical problem solving abilities was different from the average posttest score of students' mathematical problem solving abilities. which uses scientific learning. So it can be concluded that there is an effect of the Problem Based Learning model on students' mathematical problem solving abilities.

The purpose of this research are: (1) to know the influence of Think Talk Write (TTW) model of learning ability to solve mathematical problems of learners; (2) to know the effect of learning habit on students' mathematical problem solving ability; (3) to know the interaction between learning model and study habit to students' mathematical problem solving ability. The type of research used is quasi experiment with 3 × 3 factorial research design. The hypothesis test used is a parametric test with data analysis technique using Anova test. The result of the research for the prerequisite test is based on normality test which can be known by using Liliefors test and homogeneity test can be known by using Barlett test, it is obtained that the test result data from both groups are normal and homogeneous, so it can be continued for parametric test by using anava test two paths with unequal cells. Based on data processing, it is found that: (1) there is influence of Think Talk Write (TTW) learning model to students' mathematical problem-solving ability; (2) there is the influence of learning habit on the ability of mathematical problem of learners; (3) there is no interaction between the learning model and the learning habits of the mathematical problems of the learners. This means that the learning model Think Talk Write (TTW) is more effective than the conventional model so that Think Talk Write (TTW) model more influence on the problem-solving ability of learners.

The study began with observations at VIII Rengat Barat Middle School students of class VIII. This study aims to determine students' mathematical problem solving abilities using the Learnig Starts With A Question model. This type of research is experimental research (experimental research) with a quasi-experimental design research design. The research design used was The Randomized posttest-only control design. The sampling technique uses Simple Random Sampling. In this study the instrument used was a test of students' mathematical problem solving abilities. Data obtained on the problem-solving ability test were analyzed using the Independent Samples T-Test based on the results of the hypothesis test, the value of tcount = 2.014 and ttable = -1.999 with (df) n-2 and significance <0.05 (0.048 <0.05). As for the Independent Samples T-Test testing criteria, reject H0 if t> t table. Based on that, H0 is rejected because tcount = 2,014> ttable = -1,999. So it can be concluded that the students 'mathematical problem solving ability using the Learning Starts With A Question learning model is better than the students' mathematical problem solving ability using the conventional model in class VIII of SMP Negeri 4 Rengat Barat.

Students' mathematical problem solving ability is very important. But the results of the observation and supported by several studies of students' mathematical problem solving abilities are still very low. It is suspected that reciprocal teaching learning model with the help of tripships can improve students' mathematical problem solving abilities. This study aims to determine the effect of using reciprocal teaching models with fieldtrips on students' mathematical problem solving abilities. The sampling technique used was cluster random sampling with 2 classes, namely experimental class (the class was treated with reciprocal teaching learning model with fieldtrip), and the control class (the class was treated by conventional models). The hypothesis test used is the t-test. The results of the study found that there were differences in students 'mathematical problem solving abilities using reciprocal eaching learning models with fieldtrips on students' mathematical problem solving abilities. Furthermore, the mathematical problem solving ability of students with reciprocal teaching learning model is better than the students' mathematical problem solving abilities using conventional learning models. The conclusion of this study is that there is influence in improving students' mathematical problem solving ability by using reciprocal teaching learning model with fieldtrip to.
