      This study aims to determine the effect of the Type STAD Cooperative Learning model on mathematical problem solving abilities. The data collection technique was obtained by means of a test in the form of description questions and documentation in the form of a list of student names. The research instrument used was 3 pre-test and post-test questions. The data analysis technique used is the normality test, homogeneity, t test with the technique of paired samples t-test and independent t-test.      The results showed that, the paired sample t-test on the problem solving ability before and after treatment with STAD obtained an average value of 50.29 to 83.71 with a significance of 0.000 <0.05. This means that the students' scores before and after STAD learning have differences in the average mathematical problem solving abilities. Based on the results of the paired sample t-test on the ability to solve mathematical problems before and after treatment using conventional learning models, the average value was 44.57 to 75.79 with a significance of 0.000 <0.05. This means that there is a significant increase before and after conventional learning. Based on the results of the independent samples t-test, the mean values were 83.71 and 75.79 with a significance value of 0.009 <0.05. This means that there is a difference in the average problem-solving ability of students in STAD learning with students in conventional learning. It can be concluded that the STAD type of cooperative learning model has an effect on students' problem solving abilities in mathematics.

The Difference

Problem-solving ability is a characteristic of mathematical activities and a major ability in developing mathematical understanding. Mathematical problem-solving ability can be seen from several dimensions, one of which is cognitive style. Cognitive style is a unique way for each individual to acquire, process, store, use the information to respond to tasks or situations, and build knowledge. FD and FI cognitive styles are one type of cognitive style that are categorized by general ways of thinking, solving problems, learning, and dealing with other people so that they have a relationship with problem-solving abilities. The subjects in this study involved 72 students (around the age of 13-14 years), namely 33 students with FD cognitive style and 39 students with FI cognitive style. The problem-solving ability test instrument in this study was a mathematical problem-solving ability test that had been validated by experts and tested for reliability. The cognitive style test instrument is the Group Embedded Figure Test (GEFT) item developed by Witkin. The problem-solving ability of junior high school students with FI cognitive style is better than FD students even though the difference is not much different.

Problem Solving Skills

Difficulties of primary school students in solving mathematical problems that require problem solving or reasoning abilities indicate the existence of problems in the process of learning mathematics, because one of the purposes of learning mathematics in primary school is to develop the students’ mathematical problem-solving skills. As a solution to overcome the problems, this research aims at understanding how the implementation of the guided discovery learning model influences mathematical problem-solving skills. This research employs a quasi-experimental design by involving all fifth-grade students at one of primary schools in Tebo Regency, Jambi. The simple random sample was conducted to obtain class VB as experimental class, and class VA as control class. Based on the results of the final score, experiential class obtained an average score of 86.00, and control class obtained an average score of 76.93.  The results of hypothesis test using t-test obtained tcount = 2,203 > ttable = 2,020, which indicated that H0 was rejected, and H1 was accepted. Therefore, the guided discovery learning model influenced the fifth-grade students’ mathematical problem-solving skills, thus it is recommended for teachers to be able to use the guided discovery learning model in the mathematics learning process.

The purpose of this study was to study and analyze students' problems in problem-solving skills seen from their mathematical disposition level of the students on 12th grade class of  SMA IT Fithrah Insani. Method of this study is descriptive- qualitative research. From 35 students, there were three students taken as samples, consisting of a student with high disposition mathematical ability (T), a student with medium disposition mathematical ability (S), and a student with low disposition mathematical ability (R). The result of the study shows that there is a difference in the average score of students in each level of the mathematical disposition towards the conclusion of the students’ mathematical problem-solving ability test (ANOVA Test-One way). Following up on these differences, researchers identified student achievement and misconceptions on each mathematical problem-solving indicators. The results of the study show that all the student with high and medium disposition mathematical ability could not fulfill the indicators of the ability of mathematical problem solving, such as (1) understand the problem, (2) recheck the answer while all the student with low disposition mathematical ability could not fulfill all indicator of the ability of mathematical problem solving.

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.

This classroom action research was aimed at describing the improvement of students' mathematical problem solving (MPS) ability through Realistic Mathematics Education (RME). Nineteen students of VIII grade in SMP Laboratorium Undiksha in the first semester of the academic year of 2019/2020 were taken part as the research subject. This research data was collected by observation sheet and essay-test then it analyzed descriptively using simple statistics. The result of the research showed that the average score of students’ MPS ability on the first cycle equals 71,92, the second cycle equals 73,2, and the third cycle equals 75. As demonstrated, the implementation of RME could increase students’ MPS ability. Hence, the implementation of RME made students more motivated, more active on discussion and learning process, solved problems more easily, and more trained to communicate their understanding.
