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.

ABSTRACT RIZKY PRATAMA. The influence of Cooperative Learning Model Type Cooperative Integrated Reading and Composition (CIRC) against an increase in the ability of the Mathematical problem solving of students in SMP Negeri 3 Kota Tangerang. Thesis. Jakarta: Mathematics Education Courses. Faculty of mathematics and natural sciences. State University of Jakarta. 2019. The research was distributed by the student's mathematical problem solving ability are low caused still present the implementation of learning mathematics based on teachers and the lack of teachers in the conditioning provide the capability of solving mathematical problems. One of the attempts to fix it is to implement cooperative learning model type CIRC. this research aims to know the influence of cooperative learning model type CIRC against an increase in the ability of the mathematical problem solving of students in SMP Negeri 3 Kota Tangerang. This research was conducted on grade VIII in SMP Negeri 3 Kota Tangerang 2018/2019 school year. Sampling techniques using cluster random sampling by specifying a class experiment in class VIII-4 (cooperative learning model type CIRC.) and one control class in class VIII-5 (model learning conventional) of four classes randomly selected between VIII4-VIII7 class. Data analysis techniques using a t-test with a test of normality test analysis prerequisite test using the Kolmogorov-Smirnov test and its homogeneity by using Fisher test. The first hypothesis to be tested, namely an increase in the ability of mathematical problem solving of students with the influence of cooperative learning model type CIRC in class experiments. The test results showed tcalculate = 33.3147 ttable = 1.9949 and then accept H1 tcalculate > ttable criteria, meaning that there is an increase in the ability of the mathematical problem solving of students in classes that use cooperative learning model type CIRC. The second hypothesis to be tested, namely an increase in the ability of the mathematical problem solving of students with the influence of conventional learning model in the control class. The test results indicate tcalculate = 31.7777 and ttable = 1.9949 then accept H1 tcalculate > ttable criteria, meaning that there is an increase in the ability of the mathematical problem solving of students in classes that use conventional learning. The third hypothesis will be tested i.e. mathematical problem solving ability improvement is higher between the two classes. The test results indicate tcalculate = 6.0357 and ttable = 1.9949, then accept H1 tcalculate > ttable criteria on a 5% significance level, meaning there is an increased ability of the mathematical problem solving of students in classes that use the model cooperative learning type CIRC higher than those using conventional learning. The results of hypothesis testing gives the conclusion that there is an influence of the application of the cooperative learning model type CIRC against an increase in the ability of the mathematical problem solving of students in SMP Negeri 3 Kota Tangerang

Pandemic Covid-19 has a big influence on various sectors, including the education sector. This makes educators make an innovation in the learning model, which combines a model of PBL-based google meet. The purpose of this study is to analyze the presence or absence of the influence of the PBL models based on google meets on the ability of mathematical problem-solving in grade IV during distance learning. The type of research used by researchers, namely quantitative. With research design a quasi-experiment with posttest only group design. Subjects in this study were students of class IV as many as 64 students. Data collection techniques interviews and tests. While the research instrument is in the form of a posttest. Data analysis used is descriptive analysis, a test of homogeneity, normality test, hypothesis test (t-test), and test the effect size. The results showed that the average value of the posttest experimental class of 76,25 higher than the control class that is 62,18. In hypothesis testing via t-test obtained the value of sig 0.47 that where the value is smaller than α=0.05 so that H0 is rejected and H1 is accepted. This means that there is an influence of the use of PBL models based on google meet on the ability of mathematical problem-solving in grade IV. So, the use of PBL models based on google meet can be applied to learning online.

Abstract. This study aims to determine whether there are differences in mathematical problem solving abilities of students who are taught through an investigative approach and with conventional approaches in class VIII SMP 9 of Pematangsiantar. This type of research is experimental research. The population in this study were all eighth grade students of SMP 9 of Pematangsiantar as many as 8 classes. The problem solving abilities of students taught with an investigative approach to the average pretest of 57.73 and post-test of 85.42, the level of change in problem solving abilities was 27.69. Higher than the problem solving abilities of students who are taught with conventional learning the average pretest is 56.67 and posttest is 72.67. Hypothesis testing, from the calculation of student pretest data obtained at dk = 64 and the real level α = 0.05 and 𝑡(1−12∝)=𝑡0,975 obtained ttable = 1.669 and tcount = 1.172. Because tcount < ttable = (1.172 <1.669) it can be concluded that the initial ability of students is the same. While based on the calculation of student posttest data obtained at dk = 64 and the real level α = 0.05 obtained ttable = 1.669 and t count = 4.212. Because tcount> ttable (4.212 > 1.669) then Ho is rejected and Ha is accepted. Then it was concluded that there were significant differences between problem solving abilities taught by an investigative approach and conventional approaches.Keywords: Problem Solving Ability, Investigative Approach, Conventional Approach.
