This study is a quasi-experimental research using factorial design. This study aimed at finding the facts that had been resulted from the different influence caused by the use of Open-Ended method and that of STAD method on the students’ mathematical problem-solving skills in terms of learning achievement. The learning achievement was categorized into two types namely the high achievement and the low achievement. The population in this study was Grade V students from SD Negeri Serayu. The data were analyzed by ANAVA univariate test. The results of the study were as follows. First, there have been differences in the mathematical problem-solving skills of the students who had been taught using Open-Ended method and those who had been taught using the STAD method. Second, there were also differences on the students’ score. For the students who had been taught using the Open-Ended method, the highest posttest average score of their learning achievement was 95.71 while the lowest post-test average score of their learning achievement was 63.92. These students’ total average score of learning achievement was 81.04. On the other hand, for the students who had been taught using STAD the highest posttest average score of their learning achievement was 95.50 while the lowest posttest average score of their learning achievement was 70.00. These students’ total average score of learning achievement was 89.13. Third, there has not been any differences between the Open-Ended method and the STAD method.

The purpose of this study was to find out that Think Pair Share with mathematical comics is more effective than Think Pair Share learning without using comics. The research method used is an experiment with the design of Post-test-Only Control Design. The sample size was 64 students taken using cluster random sampling technique. The instrument used in this study is the Mathematical Problem Solving Test. Data analysis techniques were used using the Wilcoxon Signed Rank Test non-parametric statistical test. The results of the study showed that the learning of Think Pair Share models by using mathematical comics was no more effective than learning Think Pair Share without using comics. Although this study shows the opposite results from existing theoretical studies, in general, the use of learning media such as mathematical comics collaborated with any model can make mathematics learning more effective.

<p>This study aimed to examine the effectiveness of mobile blended compared to conventional problem-based learning on mathematical problem-solving skills and look for students' responses about the use of online learning. The study was conducted using a pretest-posttest quasi-experimental research design supported with descriptive qualitative responses involving 188 students taken by applying cluster random sampling as subjects of research distributed from vocational high schools in <em>Bojonegoro</em> City, East Java, Indonesia. Research findings revealed that mathematical problem-solving skills for students treated with mobile blended problem-based learning were higher than those who have been treated with purely problem-based learning. In addition, students have responded positively to the usage of mobile blended problem-based learning that was applicable and acceptable for effectively improving mathematical problem-solving skills.</p>

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 mathematics problem-solving ability of students in Indonesia is not high yet. The students found it difficult to do the mathematics problems that lead to solving a problem. This study aims to improve students' mathematical problem-solving skills using the Edmodo platform. The study used a quasi-experimental design to find out whether the enhancement of students' mathematical problem-solving abilities that obtain using the Edmodo Platform with a scientific approach is significantly higher than the students who obtain scientific approach learning models. The sample of the research was students in two classes X grade student Negeri 1 Parongpong, West Bandung 2019/2020. The first-class students obtained an using the Edmodo Platform with a scientific approach, while the students in the second class obtained a scientific approach learning with a scientific approach. The results showed that the enhancement of the students' mathematical problem-solving abilities in both classes was included in the moderate category. Based on the statistical tests, the students in the first class have a significant enhancement in mathematical problem-solving abilities compared with the students in the second class. Furthermore, student responses to use the Edmodo Platform with a scientific approach are categorized as "very like" and student responses to a scientific approach are categorized as "very like".
