The aim of this study was to describe and to test the effect of problem solving learning model oriented toward Balinese local wisdom (PSBLW) and type of mathematics problems (open and closed problems) on the ability to solve mathematics problem of the fifth grade students of elementary in Singaraja. This quasi-experimental research used non-equivalent control group design with pretest and posttest. The data were analyzed with factorial 2x2 analysis of covariance (Anacova). The sample consisted of the fifth grade students of Elementary School with the total of 152 students spread into 4 classes. The sample was selected by cluster random sampling. The data were collected using mathematics problem solving ability test at the 5% significance level (α = 0.05). The statistical analysis was done with the aid of SPSS 16.0 for Windows. The results showed that (1) the ability, may to solve mathematics problems of the students who learned through PSBLW is higher than those who learned through direct instructional model; (2) the students’ability to solve problems facilitated with open mathematics problems was higher than that with closed mathematics problems. The conclusion is local wisdom-oriented problem solving learning model efective to improve mathematical problem solving ability.

Introduction: Mathematical problem solving ability is very important in mathematic learning, because is can help students to solve daily life problems better. But the students mathematical problem solve ability is not high yet, one of the factor is because many students only know the standard procedures of solving mathematics problems, and when the given problem are different from the examples they tend to give up easily. This comparative design study aims to find out the improvement of students mathematical problem solving ability using Missouri Mathematics Project (MMP) learning model with individual assignments and small group assignments, and to find out whether there are differences between those two. Method: The sample in this study was VII grade students at SMP Advent Cimindi and SMP Advent II Bandung, Bandung. The instruments used in the study are mathematical problem solving test and questionnaire for response toward the Missouri Mathematics Project (MMP) learning model as the non-test instrument. Result: The results showed that the improvement of mathematical problem solving abilities of students who obtained the Missouri Mathematics Project (MMP) learning model with individual assignments and students who obtained the Missouri Mathematics Project (MMP) learning model by assigning small groups was categorized as high. Statistically, there is a significant difference in the students mathematical problem solving improvement after being taught using Missouri Mathematics Project (MMP) learning model, between students who get individual assignments and small group assignments. The response questionnaire result shows that students who acquire individual assignments like the Missouri Mathematics Project (MMP) learning model, more further the students who acquire group assignments really like the Missouri Mathematics Project (MMP) learning model.

This research was aimed to find the relationship between the fifth-grade students’ number sense and mathematical problem-solving. The participants of this study were 73 fifth grade students from a private Islamic school in Pekanbaru, Indonesia. This study applied a quantitative research method, namely a simple correlation. Instruments for measuring students’ number sense consist of 5 indicators; number concepts, multiple representations, effects of operations, equivalent expressions, and computing and counting strategies. While, the instruments to measure students’ problem-solving consist of 4 domains; numbers, fractions, geometry, and measurements. The results showed that there was a significant correlation between students’ number sense and mathematical problem-solving. After that, a correlation test was also conducted between each number sense indicator and each mathematical problem-solving domain. The indicator of computing and counting strategies has the highest correlation with measurement.

This study aimed at determining whether the PBL model and learning styles could influence the students' mathematical problem-solving and self-esteem abilities. This study was a quasi-experimental study, in which in include of two classes namely X MIPA 1 class (Mathematics and Natural Sciences); moreover, there were 24 students who used the PBL learning model as an experimental class and X MIPA 2 (Mathematics and Natural Sciences) that consisted of 22 students used a scientific learning model as a control class at SMAN 17 Pandeglang on the academic year of 2019/2020. In addition to the learning model, the students were also categorized based on visual, auditory, and kinesthetic learning styles. The data were collected by means of learning style questionnaires, problem-solving ability test, and self-esteem questionnaires. The data analysis was performed statistically both descriptive and inferential. The validity of mathematical problems was based on the expert assessment and validity test while the reliability was tested using product moment correlation. Pre-test and post-test data had been tested and both of them were homogeneous and normally distributed. The homogeneity test used Lavene test and the normality test used Chi Square. The influence test was performed using statistics, the average difference test, the two-way ANOVA test, and the Post Hoc follow-up test with Scheffe. All data were processed using SPSS. This study indicated the success by obtaining a significant value of 0.00 <α. Hence, it can be concluded that there is an effect of the implementation of PBL models and learning styles on mathematical problem-solving and self-esteem abilities.
